Snails mature at around 5 to 15 months, depending on the temperature (with cold winter temperatures inducing hibernation and delaying sexual maturity). Application of Furadan 3G @ 20 gms or Phorate 10g @ 12 gms or neem cake @ 1/2 Kg. are important predators of the banana weevil. Bunches, pseudostem and the suckers should be sprayed chlorpyriphos, Soil application with Fipronil and Bifenthrin, Nymph and adult suck the plant sap and inject toxic saliva in the tissue. Treat the cut end of the leaf petiole with Chlorpyriphos (2.5ml/lit) + 1 ml sticking agent, After harvesting of banana bunch cut the tree at base and treat it with 100ml Carbaryl (2g/lit) or apply 10g Beauveria bassiana, Swab the cut surface of the longitudinal split traps with 20g of Beauveria bassiana fungus or Heterorhabditis indica nematode and the weevils die on their own due to infection. When a cross-section is cut, the discolouration appears in a circular pattern around the centre of the rhizome where the infection concentrates due to the arrangement of the vessels. Lecture 18 - Banana: Lecture 19 - Guava: Lecture 20 - Apple: Lecture 21 - Brinjal: Lecture 22 - Chillies: Lecture 23 - Cucurbits: Lecture 24 - Cruciferous Vegs. Banana Pest and Disease Management Tamil. Virus is disseminated by suckers and Aphis gossypi. Egg period is 4 to 36 days depending on temperature conditions. Before planting, the suckers should be dipped in 0.1 per cent quinalphos emulsion. The spread of the disease is by air-borne conidia and numerous insects which frequently visit banana flowers also spread the diseaseÂ, The disease is favoured by high atmospheric temperature and humidity, wounds and brusies caused in the fruit and susceptibility of the variety, Practice crop rotation with paddy or sugarcane, Keep the field free of weeds and provide good drainage, Fruit should be free from infection and as possible before it is transported, stored and ripened. Application of bio control agents like Trichoderma viride @ 25 g for 4 times once at the time of planting in the planting pit and remaining doses at third, fifth and seventh month after planting, Application of T.harzianum Th-10, as dried banana leaf formulation @ 10g/platn in basal + top dressing on 2,4,and 6 months after planting, Dipping the planting materials in spore suspension of P.fluorescens at 10g per plant at 3,5 and 7 months after planting, Machinery and equipment should be treated with a  sanitary solution such as Farmcleanse®. Nymphs – are yellow colour, occur in under surface, Adult – yellow colour with minute fringed wings, seen in under surface of leaves, Collect and destroy the damaged leaves, flowers and fruits along with life stages, Spraying with dimethoate 30 EC - 850 ml/ha or phosphamidon 85 WSC - 300 ml/ha, Spray methyl demeton 25 EC 2ml/lit or monocrotophos 36 WSC 1ml/lit. The formic acid, with a pH of 2-3, burns the tender skins of the young fingers, leaving irregularly shaped, blackened areas on the fruits that expand as the fruits expand. Grub: creamy white legless grubs, stout and distinctly curved and swollen in the middle of the body. Destruction of weeds and alternate hosts. A. Pests of National Signifi cance ... Banana and plantains are grown in about 120 countries. The infestation of termite is more in rabbi season. The virus is isometic, linear positive sense and single stranded RNA. The nematode enters the roots as well as corms and causes usually induce reddish brown cortical lesions which are characteristic feature of the disease. Bio-control: Pathogenic nematode infecting white grub. Young bunches should be opened up to the light and air and the bracts which remain attached to the bunch should be removed especially during wet weather, The plantations should have enough aeration by avoiding overcrowding of plants, Improved sanitation helps in the reduction of the disesase, By placing polythene sleeves over the stems before hands emerge, The bunches may be sprayed with Copper oxychloride 0.25 per cent solution along with a wetting agent @ 0.5 to 1.0 ml per litre of spray fluid, Spraying of the peduncle with Carbendazim at 0.1% or Dithane M-45 at 0.1% after shoot emergence. Use certified suckers free from nematodes. Some ant species associated with banana bunches can cause significant damage to young fruits, especially when colonies of the ants on bunches are disturbed or agitated by bunch spraying or by bumping into plants and causing vibration disturbance to the ants. They appear to be “bunched” at the top of the plant, the symptom for which this disease is named. Conidia are narrow and multiseptateÂ, Perithecia are dark brown to balck, amphiceous, erumpent, ostiolate, Asci are oblong, clavate. The fungus attacks the young banana fruits usually at the distal end, At the initial stage, small, circular, black spots develop on the affected fruits. Spray soapy water or insecticidal soap  on plants thoroughly on petioles, furled leaves, whorls or on young suckers, Spray Dimethoate (75ml/100lit) or Diazinon (1.5ml/lit) or Acephate (1.3g/lit) on infested plants and suckers, Spray Methyl Demeton 25 EC 0.05% or Monocrotophos 36 SL 0.072%, Inject Monocrotophos 36 SL 1 ml/plant (1ml diluted in 4 ml of water). per pit at planting. They have six segmented antennae and prominent dark veins Banana Production Technology Tamil. The upper portion of the peduncle is exposed to the hot sun, when the bunch emergence occurs during summer months and due to reduced functional leaves reducedÂ. The disturbed ants eject formic acid from their abdomens as a defense reaction. Traditional pest and disease identifica - Since scale insects may occur on all plant parts, every part of the plant must be checked. Nymph and adult infest leaves, pseudostem and fruits. Puthunagaram, Kodumbu, Peruvembu, Mundur, Puthuppariyaram, Marutha Road, Kannadi, Koduvayur, Chittur-Thathamangalam, Mathur, Pirayiri, Vadavannur and Thenkurissi are some of the vulnerable areas in the district, Giant East African Snail has a narrow, conical shell, which is twice as long as it is wide and contains 7 to 9 whorls when fully grown. Pupa: white and about 12 mm long. They live partially or completely within roots, feeding on the outer cortical cells. Proper fertilization prevents the infection, Protective spraying when the fruit is still young with Bordeaux mixture 1%, Pre-harvest spray with Prochloroz 0.2% or Carbendazim 0.1% or Chlorothalonil 0.2% four times at fortnightly interval is highly effective, Post harvest dipping of fruits in mycostatin 440 ppm or Aureofunginsol 100 ppm or Carbendazim 400 ppm or Benomyl 1000 ppm, The distal bud should be removed when all the hands opened to prevent infection. Infested plant shows yellowing and withering of leaves, slowed plant growth, root destruction, reduced fruit production. Grub period is 20 to 25 days Seen in … Banana aphid populations are often tended by ant species. Do not produce bunches. , 1996; Elay abalan et al. The larval period lasts about 8-10 days. View full-text. Pistils should be removed 8 to 11 days after bunch emergence. The Indo-Malayan region is believed to be the place of origin. In the advanced stages of disease, affected plants may have a spiky appearance due to prominent upright apical leaves in contrast to the skirt of dead lower leaves. The incubation period ranges from  3 to 8 days.Â. The infection, which occurs in perianth, spreads to fingers causing blackening of the skin, shrinkage and folding of the tissues. Collect and destroy the affected plant parts, Spray application of monocrotophos 36 WSC 0.04%. Areas with untreated garbage and places of water logging are their favourite spots, Crop rotation, enhancement of soil quality, choice of resistant varieities, water management, providing mechanical barriers, post harvest treatment. The nymphs and adults congregate under the outer base of the pseudostem, Aphids always accompanied by ants, which act as dispersing agents of nymph, Honey dew secretion appears on the plants which attracts the ants, The aphids suck the sap of the plant and reduce the growth and vigour, They also act as a vector of Banana Bunchy Top Virus (BBTV).             Scales, especially armored scales are very difficult to control when mature. Any number of banana pests and diseases can derail a successful plantation, however, not to mention environmental banana plant problems such as cool weather and high winds. FAO Code of Conduct on the Distribution and Use of Pesticides (1982, … During the advanced stages of infestation,  when split open the stem, exhibits extensive tunnelling both in the leaf sheath and in the pseudostem, Rotting occurs due to secondary infection of pathogens and a foul odour is emitted.Â. Remove plant residues after harvest. Crop Nematode Pest. Suckers were trimmed and dipped in slurry solution and sprinkled with carbofuran @ 15 g per sucker. Affected plant parts - Article: AI-powered banana diseases and pest detection A recent paper has been published and examines the use of Artificial Intelligence in 'just-in-time' crop disease detection in banana. For a complete list of exotic pests of banana, contact Australian Banana Growers’ Council for a copy of the industry biosecurity plan. Such traps are laid randomly in the field @ 25 traps per acre. Fact sheet on rugose spiralling whitefly, a recent invasive pest of coconut, banana and several other host plants in South India . Adult : Small to medium sized aphids, shiny, reddish to dark brown or almost black. Eggs are laid just below the fruit or pseudostem surface. Identification of pest: Larva - Pale greenish brown with dark marking. Many students always searches about TNAU study material and TNAU agriculture notes but they didn't get it because of some misleading sites. Castor hairy caterpillar, Pericallia riciniÂ, Home | About Us | Success Stories | Farmers Association | Publications | Contact Us, Grubs bore into the rhizome and cause death of the plant. Palakkad has been identified as the most vulnerable district with the study predicting attack in 22 locations. Grubs bore into the rhizome and cause death of the plant. The RNA is surrounded by a protein coat consisting of 32 copies  of single structural protein which form isometric particles, The primary transmission is through use of infected daughter suckers from diseased palnts and the secondary spread of the disease is through melon aphid, Aphis gossypii  and Aphids maidis, Infected suckers should not be used for planting, Growing pumpkin, cucumber and other cucurbits between the rows of banana crop should be avoided, Dry heat treatment of suckers at 40 degree C for one day inactivated the virus, Early detection by regular inspection of planting and eradication of diseased plants from the field as soon as they are noticed, Use of high input crop management of system comprising of 10 kg farm yard manure at the time of planting and subsequently at an interval of 3 months. Pupal period is 5 to 7 days  Insects That Eat Banana Leaves. Apply castor cake 250g or carbaryl 50g dust or phorate 10g per pit before planting also prevents infestation. Dry rot also occurs in the pulp and the affected tissues become dry and fibrous. Sun hemp and chrysanthemum should be grown 45 DAP of Banana and incorporated into the soil one month later. Footwear, which may have contacted banana plants or soil around banana plants elsewhere, should not be worn on the farm. Initially, dark green streaks appears in the veins of lower portion of the leaf midrib and the leaf stem. Though occasionally large populations are seen, economic damage is negligible. Seed treatment with Chlorpyriphos 20 EC @ 6 ml/kg seed or acephate 75SP @ 4 gm / kg seed. Faculty TNAU kat@tnau.ac.in: Download: 4 Breeding of Field & Horticultural Crops Faculty TNAU kat@tnau.ac.in: Download: 5 Comprehension & Developing Comm. The disease is known to occur in all banana-growing states. Later the disease spreads and affects the whole bunch. The infested fruits get spotted and their flavour is affected. The abdomen is often darker than the head and thorax. Disc-on-stump traps consist of corm slices placed on top of harvested plants cut at the rhizome. Destroy all the volunteer plants and that could act as a source of thrips to spread to other plantings. Pre-sowing soil treatment with Phorate 10G or Quinalphos 5G or Carbofuran 3G @ 300 gm / gunta and treatment of planting materials with Chlorpyriphos @15-20 ml/kg of sukers. Disc-on-stump traps can be used for trapping weevils. ... Standard Operating Procedure for Integrated Pest Management . The planting tools should be cleaned before being used in the field, Well decomposed manure should be used, Grow marigold in the inter space which serves as repellent and trap crop, Covering the field for 6 to 8 weeks with plastic after tilling and watering raises the soil temperature. Pests and diseases that affect the banana industry are listed below. Banana should not be grown along with onion and other vegetables.Â. Soil incorporation at the time of planting: carbofuran 3 G 10g, phorate 10 G 5 g/plant, lindane 1.3 D 20 g/plant. 1 kg neem cake, 200 gm nitrogen, 40 gm phosphorus, 200 gm potassium per plant, 4 weeding at 2 months interval up to 8 months stage, Spraying Methyl Demeton 0.03 per cent (0.3 ml/lit of water) at 3 to 4 weeks interval controls the vector and reduces the spread of the disease, Foliar spray of micronutrient (0.2% CuSo4(2ml/lit), 0.2% FeSo4(2ml/lit), 0.5% ZnSo4(5 ml/lit) and 0.1% H3Bo3(1 ml/lit of water) at 3,5 and 7th month after planting and spraying Glyphosate 2Kg per hectare to control weeds, Control of insect vector by spraying Phosphomidon at 1 ml per litre or methyl demeton at 2 ml per litre or monocrtophos at 1ml per litre. Later on, the centre of these spots turns to light grey colour surrounded by yellow halo, The spots often coalesce to form large irregular patches of dried tissue, Rapid drying and defoliation of leaves are the characteristic feature of this disease, Normally 15-18 leaves are necessary at the time of shooting for bunch development, but due to Sigatoka leaf spot it is difficult to maintain 15 leaves, In severe cases, immature bunches fail to fill outÂ, The fingers of bunch in affected plants tend to remain undersized and angular but pulp starts ripening, This disease is caused by Mycospharella musicola fungus by the characteristics of the conidia and conidiophores, The conidiophores are bottle shaped and bear conidia. Pupation takes place in holes bored by the grubs. The central core of the pseudostem is used as a vegetable. The infested fruits fetch low market value in case of severe scarring of the fruit skin. Heavily infested plants appear unhealthy and produce little new growth. Inspect plants closely at weekly intervals, especially plants where scale problems have occurred in the past. Marigold (Tagetes spp) grown as an intercrop cum trap crop in Banana field resulted in significant reduction of root lesion nematode population and increased the yield. Natural enemies - Predatory ants such as the bigheaded ant (Pheidole megacephala) and Tetramorium spp  feed the eggs, grubs and pupae of weevils. They are not toxic to humans and animals (In organic culture, consult your certification body before use), Feeding injury on young banana bunches and fingers. In case of severe infestation spray as in case of stem borer. All these problems contributed to a new way of thinking concerning pest control practices, i.e. Internally, symptoms first become obvious in the xylem (water conducting) vessels of the roots and the rhizome. per pit at planting. Such plants do not produce bunches but as a virus reservoir, The casual agent of this disease is Cucumber mosaic virus(CMV). Without its natural predators it has assumed major pest status. Their eggs are laid in batches of 100-400 and are spherical to oval in shape, approximately 5 mm in diameter and cream to yellow in colour. Heavily infested plants soon develop a black sooty appearance from mould growing on the sugary secretions that the whitefly immatures excrete. The shell is generally reddish-brown in colour with weak yellowish vertical markings. Banana (Musa spp.) Banana is otherwise called ‘Apple of Paradise’. Control. Symptoms of damage. Scales cannot fly; therefore they do not readily infest plants as do most other insects. Remove and destroy infested plant material after harvest. Banana aphid; Banana flower thrips; Banana fruit caterpillar; Banana rust thrips; Banana scab moth; Banana weevil borer; Banana-silvering thrips; Banana-spotting and fruit-spotting bugs; Cluster caterpillar; Fruit piercing moths; Queensland fruit fly; Spider mite; Two-spotted mite; Sugarcane bud moth; Diseases. Avoid injection of Monocrotophos after flowering, Introduction braconid wasps, Lysiphlebius testaceipes as parasitoid to parasitize the aphids, Release predators such as lady bird beetles and lace wings in the field which are very active aphid feeders, Apply bio control agents like entomopathognic fungus, Beauveria bassiana in the banana fields, Newly planted banana fields are easily susceptible to infestation. Banana is otherwise called ‘Apple of Paradise’. Adult - Female circular, semi transparent and pale brown. It is widely used as a fresh fruit. Sucker selection from disease infested field should be avoided. Disc-on-stump traps consist of corn slices placed on top of harvested plants cut at the rhizome. Banana trees (Musa spp.) Such affected plants easily collapse. The banana … The emerging larvae are fleshy, yellowish  white and apodous.  The larvae feed on tissues of the succulent sheath by tunnelling extensively and may reach as far as the true stem Yellow and purplish spots in the sub marginal areas.Â. The banana plant, Musa paradisiaca, is the world's largest herbaceous perennial plant and belongs to the family Musaceae.It is grown for it's fleshy, curved banana fruit. This disease is more pronounced on young suckers leading to rotting and emitting of foul odour, Roting of collar region is a commonest symptom followed by epinasty of leaves, which dry out suddenly, If affected plants are pulled out it comes out from the collar region leaving the corm with their roots in the soil, Splitting of pseudostem is common in late stage of infection in cultivars Robusta, Grand Naine and Thella Chakkerakeli, When affected plants are cut open at collar region yellowish to reddish ooze is seen, In early stage of infection dark brown or yellow water soaked areas are more in the cortex area, In advance stage the interiror lesions may decay to such extent that cavities surrounded by dark spongy tissues are formed, This soft rotting may spread radially towards growing point through the cortical tissues. Use mechanical barriers in the field. This insect sometimes live in the heart of the pseudostem within the roll of the central leaf. Anthracnose; … Are sedentary endoparasites. Regular checking of fruit under the bunch covers is essential to ensure that damage is not occurring. Use of salt to kill the pest as it alters the soil pH, The application of salt will become untenable during rainy days, The meat of the snails thus killed will rot with foul smell, Release predators  like predatory snail (Euglandina rosea), flatworms (Platydemus manokwari) and  pathogens in the field,  Metal salt-based molluscicides as snail baits and snail pellets. Fore wing - Stout moth with wavy white markings on the brown. The efficiency of the traps depends on their numbers and frequency of trapping. The development of feeder roots is affected in case of high population of nematodes in the soil. Such plants are readily blown over and the roots are exposed. The use of nematode-free planting material on uninfested land, Trim the corm  tissue  until   all  black or discolored spots have been removed, leaving only clean white tissues, Wash corms in running water, and allow them to dry before planting. The incidence is high in acid alluvial soils. Banana stumps kept in the field after harvest must be removed and destroyed as they serve as weevil refuges and breeding sites, Blackened mass coming out from pseudostem, Pale yellow streaks on the upper surface of leaves, Centre of the spots turns to grey colour, Microscopic view of Mycospharella musicola, Apply mud slurry mixed with neem oil 5% on the pseudostem five month after planting in heavily infested areas to prevent oviposition, Closely monitor the plants for the detection of oviposition punctureszxzsxz, Spray chlorpyriphos 20 EC or quinalphos 25 EC 2ml/lit. Collect and destroy egg masses and caterpillars, Use burning torch to kill the congregating larvae, Use light trap to attract and kill the adults, Spray chlorpyriphos 20 EC or quinalphos 25 EC 2ml/lit, Young larvae feed by scrapping the leaves from ventral surface. The pared sets should be dipped in a Bordeaux mixture – DBCP paste (made by mixing 20 kg hydrated lime, 20 kg copper sulphate, 1288 ml 70% DBCP and 455 litres of water). Light yellow streaks run parallel to leaf veins giving the leaf a striped appearance. A single sac contains several hundred eggs. It is widely used as a fresh fruit. Identification of pest. Bunch covers (which cover the full length of the bunch) protection applied very early. Root and rhizome necrosis is manifested by the retarded growth, leaf yellowing and falling of mature plants. It is widely seen in groundnut crop and chilies of sandy loam soil. Apply Chlorpyriphos 20EC @ 400 ml / gunta with irrigation water. Banana scale moth caterpillars feed on young leaves, which show scale like scars and refuse of larvae. The banana aphid is a significant pest of banana and acts as vector for virus causing banana bunchy top virus (Hu et al. Submerge trimmed suckers for 20-25 minutes in hot water at 53-54°C. Skills in Eng Faculty TNAU kat@tnau.ac.in: Download: 6 Crop Pests & Stored Grain Pests & their Mgmt Faculty TNAU kat@tnau.ac.in: Download: 7 Crop Physiology Faculty TNAU Spray 0.0 % Carbaryl on the host plants. Infestation begins at the base of the outermost leaf-sheath and in injured tissues at the lower part of the pseudostem. Caterpillar scraping the chlorophyll content and windowing in unfurled leaves. Later on feed voraciously at night on the foliage. These are derived from iron phosphate, copper sulphate and aluminium sulphate. Use Longitudinal Split Pseudostem Traps (LPST) – This traps (45cm long) are made from the pseudostem pieces cut longitudinally in two halves. The casual organism is Fusarium oxysporum f.sp.cubense. The Indo-Malayan region is believed to be the place of origin. Nymph - Oval translucent, Yellowish brown with waxy coating. Novel and rapid methods for the timely detection of pests and diseases will allow to surveil and develop control measures with greater efficiency. Drench with Methoxy Ethyl Mercuric Chloride (Emisan-6) 0.1 / or Sodium hypochlorite 10% or Bleaching powder 20g /litre/tree. About 60 mg of Pseudomonas (in a capsule) can be applied in a 10 cm deep hole made in the corm. TNAU Agritech Portal :: Crop Protection. Collect and destroy the damaged plant parts, Spray application of azinphosethyl, chlorphyriphos and monocrotophos, Severe infestation – spot application of Bt, Foliar spray with avanthe 1 ml in 100 ml of water, Field release of entomopathogenic fungus,Â. MApps C-DAC Hyderabad. It is an obligate-outcrossing hermaphrodite, which means that one externally fertilised snail can establish a population . Planting of infested suckers do not establish and delay growth. White Grub is a polyphagus pest  and feed on almost all kharif season crops. If the scales are not controlled, leaves will drop prematurely, sometimes killing portions of twigs and branches. 5 images. Avoid mattacking (leaving the plant after bunch harvest for recycling of nutrients) in weevil endemic areas. These turn a reddish-brown to maroon colour as the fungus grows through the tissues. CO-PI: 68: Standardization of mat system of cultivation for continous harvest of banana Cv.Grand Naine: TNAU-NADP-Precision farming One year. Field release coccinelid predators such as lacewings and ladybird beetles exert some control over rust thrips on the plant, and ants may be effective in removing some of the pupae in the soil.            The beetles feed on the young leaves and skin of young fruits. Before planting, neem cake and pungam cake @ 200 g should be applied per pit. Yellowing of leaves and rusty growth over fruit. In case of only serious damage caused by the beetles spray the plants with Aldrex 30 EC @ 0.25% ai or dust with Malathion dust. When the true stem and peduncle are tunnelled after flowering, the fruits do not develop properly, presenting a dehydrated condition with premature ripening of the bunch itself. This is a monomorphic species; workers are similar in appearance regardless of their duty within the colony. Meloidogyne spp. Hind wings - white having a brown patch along the margin. Use healthy and pest free suckers to check the incidence, Do not dump infested materials into manure pit. After harvest, the bunches should be transported to the store house without causing any bruises to them.  The transported bunches should be stored carefully at 7 to 10 degree c. Avoid contamination in collecting places, during transport and in ripening rooms, The disease is characterized by the presence of spindle shaped pinkish to reddish streaks on pseudostem, midrib and peduncle, Typical mosaic and spindle shaped mild mosaic streaks on bracts, peduncle and fingers also observed, Suckers exhibit unusual reddish brown streaks at emergence and separation of leaf sheath from central axis, Clustering of leaves at crown with a travelers palm appearance, elongated peduncle and half filled hands are its characteristic symptom, The disease is caused by a virus belonging to potyvirus group. They cause rotting of the corms and act as a vector to the fungus Fusarium oxysporum. They are borne at the ends of tapering phialides, aggregated into rounded, mucilaginous translucent heads. Second stage juveniles emerge from the eggs, move towards the roots and penetrate the roots either at the root tip or in regions of previous penetration or where minor wounds are present.The eggs are laid within a gelatinous matrix to form an external egg sac or egg mass. After harvesting the bunch remove and destroy the pseudostem from ground level so as to avoid it serving as a breeding site for the pest. Spray Copper oxychloride or Zineb with gas oil or mobile oil or white oil. Remove infected plants immediately. Attacks by nematodes, combined with the effects of secondary rot organisms, destroy or weaken much of the root system. BORERS Complete life cycle within four to six weeks, Burrowing nematode – eggs are laid in the corms and roots.2 weeks are required for the life cycle to be completed. It is known from India (Gujarat and Tamil Nadu) and Indonesia (Bogor). They often confine themselves within the pseudostem and in the decomposing tissues of harvested pseudostems. Scales also feed on trunks and stems of plants. The disease is soil borne and the fungus enters the roots through the fine laterals. Before planting, the suckers should be dipped in 0.1 per cent quinalphos emulsion. Egg: elongate-oval, about 2 to 3 mm long and white in colour. Conidiophores are cylindrical, tapered towards the apex, hyaline, septate, branched and sub-hyaline towards the base, each with a single terminal phialidic aperture. Symptoms of damage. India leads the world in banana production with an annual output of about 14.2 million tonnes. Cut the banana plant after harvest at the ground level and treat it with carbaryl (1g/liter) or chlorpyriphos (2.5 ml/lit) at the cut surface. Plants are easily blown down by mild to strong winds. The pseudostem weevil O. longicollis is a specific pest of banana and reported as a major pest from India, Bangladesh, Burma, SriLanka and Indonesia (Dutt and Maiti, 1970). The adults over-winter on citrus or non-crop native or exotic ornamentals, and start to move into lychee and longan orchards in spring when the trees flower.
