Description

A kind of microorganism trapping bait and application
Technical field
The invention belongs to agricultural science injurious insect control technical field, be specifically related to a kind of microorganism trapping bait, and the application in trapping male and female fruit fly, liriomyza bryoniae.
Background technology
Diptera (Diptera) is 1 order of Arthropoda (Arthropoda), Mandibulata (Mandibulata), Insecta (Insecta), Pterigota (Pterygota), is to be only second to coleoptera, Lepidoptera, hymenopteran the fourth-largest order in Insecta.Known 85000 kinds of the world, distribution on global.China known more than 4000 plants.Dipteral insect has a pair wing and a pair haltere, comprises mosquito, fly, horsefly.Some monoids of common diptera such as kind of a fly, leaf are dived the larva of fly, fruit fly, wheat cecidomyiia etc., are all the important pests of agricultural.Agromyzidae is caused harm multiple leguminous plant; The numerous species of Tephritidae is caused harm oranges and tangerines, pears, peach etc.
Fruit fly belongs to diptera Tephritidae (Tephritidae), is class important pests fruits and vegetables class crop being caused to heavy losses.Tephritidae is known about 500 genus up to now, more than 4500 plant, wherein, the monoid that fruits and vegetables class is harmful to trypetid reaches 15 genus, 22 subgenus, more than 150 kinds, [Bactroceradorsalis (Hendel)] is closed with dacus dorsalis in China, melon trypetid [Bactroceracucurbitae (CoqilLett)], citrus fruit flies [Bactroceraminax (Enderlein)] etc. are comparatively common, are mainly distributed in the provinces such as Hunan, Hubei, Sichuan, Chongqing, Guizhou, Fujian, Guangdong, Guangxi, Hainan, Yunnan, Taiwan.The host range of harmful trypetid is very wide, relates to economic fruit class plant and amounts to 24 sections, 42 genus: vegetable plants 4 section, 16 belongs to (wild host plant is not included).Fruit fly fertility is strong, harmfulness is large.In trypetid distribution or Endemic Area, host volatiles rate of damage average out to 25-45%, up to 80% time serious, even has no harvest, and brings heavy economic losses to fruits and vegetables class crop, has had a strong impact on peasant and has increased production extra earning.
At present, the method for preventing and treating Fruit fly mainly contains cultural control, chemical control, physical control and biological control etc.Wherein cultural control comprises band wormed fruit reality, fruit bagging and the pupa etc. that goes out of turning over winter regularly removed in plantation; Chemical control methods mainly sprays Bait on Killing trypetid; The technology that physical control measure adopts trypetid trapping bait and poison bait to combine, at present, for preventing and treating the trapping bait mainly chemosynthesis trapping bait of trypetid, as lured ketone (cuelure), methyl eugenol (methyleugenol) etc.Take a lot of work due to during cultural control measure expense, effect is bad; Chemical control not only easily makes trypetid develop immunity to drugs, and is harmful to people, animal, easily produces the problem of the environmental pollutions such as residue of pesticide; There is again the problems such as volatilization is fast, the lasting period is short, medication is frequent in property trapping bait in actual applications, and what do not reach control borer fruit rate prevents and treats object, and current most widely used general trapping bait methyl eugenol only lures male worm etc., and its application is restricted.
Sugar-vinegar liquid, female sex hormone, protein three major types lure is had both at home and abroad for trypetid.Sugar-vinegar liquid is time-consuming, effort, and cost is higher; Female sex hormone can only lure male worm, and due to the capable multiple mating of male worm energy, preventive effect is often not ideal; Protein-based trapping bait can lure female male worm, effective.But the protein lure at present on overseas market is pure animal protein, and production cost is high.
Americal rice leaf miner (LiriomyzasativaeBlanchard) also belongs to diptera Agromyzidae (Agromyzidae) Liriomyza (Liriomyza), being commonly called as vegetable leafminer, map worm, scrawly handwriting etc., is the dangerous pest that leaf mining is caused harm.China early than in December, 1993 at Sanya, Hainan Province Late Cambrian, Americal rice leaf miner northwards spreads gradually subsequently, 1994 at Kunming, Yunnan occurring and damage, nineteen ninety-five occurs on Shanghai and Nanjing and other places, 1996 in Shandong, Beijing population outbreak, 1997 in Henan, Shanxi occurs, 1998 northeastward, the Inner Mongol causes disaster, except Tibet, all there is distribution in the whole nation.Its host plant reaches more than 200 and plants, and wherein vegetables are injured the heaviest with solanaceous vegetables (except pimento, capsicum), beans, melon, Carrot family etc.
Adult of Liriomyza Sativae Blanchard is small-sized fly class, body black, and long 1.3 ~ 2.3 millimeters of body, in 8.7 ~ 12.6 days life-spans, every female all one's life lays eggs 70 ~ 125 pieces, and incubation rate is up to more than 90%.Larva milky is to faint yellow, and long 3 millimeter, year bred for 15 ~ 20 generations.Enter winter in greenhouse by solar heat, can endanger in the four seasons, mainly contain 2 hazard booms, appear at 5 ~ June and 9 ~ October respectively, year can reach 20 generations more than from generation to generation.Adult, larva all can endanger, female adult pest acanthopore on host's blade also takes food wherein and lays eggs, larva is potential food mesophyll or petiole after the subcutaneous hatching of blade table, produce irregular snakelike white gallery, destroy leaf chlorophyll, affect photosynthesis, time serious, the withered and yellow even whole strain that comes off of blade is withered; Cause seedling stage and ruin seedling.Endanger serious field to be injured strain 100%, blade is injured 70%.Abound with phase custard squash, after discovery harm, within about 7 days, suffer all mesophyll, destruction in about 15 days.Larva and adult also can propagate some virus disease by taking food.
At present; along with the change of cropping system; continue the continuous expansion of warm winter phenomenon and open country and vegetable at protected field area; Liriomyza has become and various vegetables has endangered one of especially big, disastrous insect preventing and treating exceptionally poverty-stricken difficulty; annual generation is many from generation to generation and overlap is chaotic; its spread in china is fast, and autumn land for growing field crops the end of spring and the beginning of summer, protecting field occurred especially serious the whole year.The Protectorate cultivation of vegetables is that vegetable leafminer provides good hibernacle.This worm not only can survive the winter in booth, and can in canopy occurrence injury, become the important worm source in outdoor vegetable field.Therefore, the control done well in booth can prevent this worm after taking off canopy effectively to outdoor vegetable diffusion harm.
Because this worm generation overlap phenomenon is serious, pesticide resistance is strong, more difficult control in production.At present, in production to the control of Americal rice leaf miner still mainly based on chemical control, in order to solve the food-safety problem that chemical pesticide for many years brings, bio-control method should be utilized to control insect pest, but biological prevention does not also have real application in production and performance benefit, and find with strong points, preventive effect is high, and to people, animal safety, do not have the new lure of the one of environmental pollution extremely urgent.
