1, main prevention and control measure
Follow the theory of " environment protective plant protecting ", for Banana Growth 4 main period (take out flower bud early stage, take out flower bud and young fruit period, fruit expanding period and gather the later stage), selectively integrate variety adoption, host's isolation, cutting off male flower cluster bagging, Qing Yuan protect bud, Healthy culture, physics and chemistry lure the prophylactico-therapeutic measuress such as control, Biological control and emergent medication, give full play to their interaction, assemble the banana flowers thrips green prevention and control method being applicable to each trophophase, build a kind of sustainable control technology mode of green from the harm of source prevention and control banana flowers thrips.
(1) variety adoption
Before banana planting, the anti-thrips harm ability of kind should be taken into full account.As 3 kinds of Fructus Musaes such as ' Williams ' Fructus Musae that hot-zone, Fujian is planted, red any of several broadleaf plants and dwarf banana carry out field insect resistace qualification, it is shown that the ability of ' Williams ' Fructus Musae anti-banana flowers thrips harm is the strongest, red any of several broadleaf plants is the most weak.Therefore, should according to the banana flowers thrips of different regions Jiao Yuan, a situation arises, select to be suitable for the Fructus Musae pest-resistant cultivar of locality plantation, and cultivate healthy and strong group training any of several broadleaf plants Seedling.
(2) host's isolation
Banana flowers thrips is except harm Fructus Musae; also it is the common insect pests taken of the various plants such as Cruciferae, Cucurbitaceae, pulse family, Solanaceae, Rutaceae; therefore should avoid around Jiao Yuan planting this type of flowering plant as far as possible; or plantation one fixed width banana flowers thrips non-host plant make isolation strip; both the worm source quantity of periphery, any of several broadleaf plants garden banana flowers thrips can have been reduced, it is possible to play the effect attracted with Protect natural enemies.
(3) cutting off male flower cluster bagging
The elongation growth of alabastrum, not only can consume nutrient, and banana flowers thrips can be attracted to take food and lay eggs, increase the weight of the occurring and damage of banana flowers thrips.Therefore, when, after instaminate flower relieving accumulation of pathogens bundle, at the timely cutting off male flower cluster of fine day or afternoon, and blue film bagging being used after cutting off male flower cluster in 7-10 days in time, reduce worm source, alleviate the degree that causes harm.
(4) bud is protected in clear garden
After Fructus Musae is gathered, leave and take suitable bud of inhaling and be remarkably improved the yield of Banana tree of lower generation, generally leave and take " eight " word bud that ventilation and penetrating light condition is better and more sturdy, avoid staying the bud of water sucker, hole limit bud and fruit ear vertical position, after locate inclination at maternal plant overhead about 1.2m and break apart by chopping stem stalk and reject unnecessary suction bud；After staying bud, clear garden comprehensively, cut stem stalk and the leaf of broken maternal plant on the spot, every mu is spread fertilizer over the fields 35-70kg quick lime or sprays other soil sterilants and plough deeply afterwards, can kill the pupa of banana flowers thrips and worm source of surviving the winter in soil, reduce worm of lower generation source radix, again can partially acidic in sweetening of the soil, and the broken any of several broadleaf plants bar any of several broadleaf plants leaf in garden is all covered under soil, allow its abundant retting rot, increase the soil organism.
(5) Healthy culture
Performing on the basis of any of several broadleaf plants garden health, rational close planting and in good time intertillage, focusing on go out pupa, rich water quality management and immunity of soil and lure the work such as anti-.Before any of several broadleaf plants seed is planted, soil needs to soak, teds, sterilize (every mu is spread fertilizer over the fields 35-70kg quick lime or sprays other soil sterilants) and whole furrow etc. process, and can kill the pupa of banana flowers thrips in soil.During plantation, in good time watering, fertilizing, pass through soil measurement formula, reasonably combined nitrogen phosphoris and potassium fertilizer ratio, suitably feed micro-fertilizer, bacterial manure (is taking out flower bud and young fruit period respectively, fruit expanding period recommends to add bacterium solution 300-500 times of liquid irrigating root 1-2 time for flowers and fruits, every minor tick 10-15 days) and plant activation protein (take out flower bud early stage recommend with 3% 500-1000 times of pouring root of plant activation protein wettable powder or spray 2-3 time, every minor tick 25-30 days), promote robust plant growth, activate plant self-defensive system, while strengthening plant insect resistace, accelerate alabastrum bract to open, and divest useless bract in time.
(6) physics and chemistry lures control
1. colour table lures control
Utilize the banana flowers thrips sensitivity differences to different colours, taking out flower bud and young fruit period, recommending every strain Fructus Musae to be about 20cm place suspension 1 from alabastrum surface lures worm colour table to lure collection any of several broadleaf plants flower thrips adult, it is possible not only to monitor the occurrence dynamics of this worm, also can reduce it lay eggs and cause harm, efficiently reduce population number, reduce the consumption of chemical pesticide.Test shows, orange most sensitive in yellow of banana flowers thrips；Orange luring worm colour table suspension height to be advisable so that colour table bottom is concordant with alabastrum shoulder, hang is advisable with the long limit of colour table for bottom, and the field gathering effect of banana flowers thrips is best, can be used for the monitoring of this worm and preventing and treating.
2. pheromone lures control
Lure control in conjunction with colour table, lure worm colour table adds at every and 1 banana flowers thrips pheromone lure is installed, collect any of several broadleaf plants flower thrips adult with luring collaborative the luring of worm colour table, monitoring and control banana flowers thrips field insect population radix, reduce egg laying amount, reduce chemoprevention pressure, it is achieved green insect protected.
(7) Biological control
Biological control be a kind of safely, effectively, lasting pest controlling method, using of chemical pesticide can be greatly reduced, major measure includes release, Protect natural enemies and uses biological pesticide.
1. Predatory Mites is discharged
The hostile banana flowers thrips in Predatory Mites sky such as Si Shi amblyseius as predatory mite, Amblyseius barkeri, amblyseius cucumeris oudeman, the former amblyseius as predatory mite in river, the nearly blind peaceful demodicid mite of Fructus Citri Limoniae, the little blind Sui Manheluan garden of Switzerland very peaceful demodicid mite have search and predation preferably and commercialization at home；As 5≤every average population amount < 15 luring worm colour table, recommend the Predatory Mites products such as 1 bag of Si Shi amblyseius as predatory mite of every Fructus Musae rime, Amblyseius barkeri or amblyseius cucumeris oudeman, not only can effectively control the banana flowers thrips insect population radix outside alabastrum, the banana flowers thrips piercing alabastrum internal layer bract also be had and better controls effect.
2. conservation of nature natural enemy
Except Predatory Mites; the sky hostile banana flowers thrips such as minute pirate bugs (Similis, shoulder hair minute pirate bugs, Orius and Orius minutus etc.), parasitic wasp (chalcid fly etc. nibbles in Ji chalcid fly, clan), Chrysopa (Chinese green lacewing, chrysopa septempunctata etc.), ladybug (coccinella septempunctata, Propylaea japonica etc.) also have certain control action, also should be protected by utilizing.As in conjunction with host's quarantine measures, the SHENGCAO such as the Ageratum conyzoides in any of several broadleaf plants garden surrounding plantation one fixed width, both extraneous natural enemy can have been attracted to enter garden breeding, be alternatively natural enemy the transition period lacking prey provide deliver for foodstuff and perch, spawning place, again can as nutritive element contents such as the organic matter in the abundant soil of green manure and N, P and K；Meanwhile, use banana flowers thrips efficient, to natural enemy low toxicity or nontoxic biological or chemical pesticide, it is prevented that natural enemy populations is subject to catastrophic collapse in good time.
