Description

A kind of microorganism trapping bait and application
Technical field
The invention belongs to agricultural sciences injurious insect control technical field, and in particular to a kind of microorganism trapping bait, and luring Catch the application in male and female fruit fly, liriomyza bryoniae.
Background technology
Diptera (Diptera) is Arthropoda (Arthropoda), Mandibulata (Mandibulata), Insecta (Insecta), 1 mesh of Pterigota (Pterygota), is that coleoptera, Lepidoptera, the 4th of Hymenoptera the are only second in Insecta Big mesh.85000 kinds known to the world, distribution on global.More than 4000 plant known to China.Dipteral insect has a pair of of wing and a pair of of balance Rod, including mosquito, fly, horsefly.Some monoids of common Diptera such as Hylemyia Platura Meigen, leaf are dived the larva of fly, fruit fly, wheat cecidomyiia etc., are all agricultures The important pests of industry.Agromyzidae is caused harm a variety of legumes;The numerous species of Tephritidae are caused harm citrus, pears, peach etc..
Fruit fly belongs to Diptera Tephritidae (Tephritidae), is to cause heavy losses to fruits and vegetables class crop A kind of important pests.Tephritidae hitherto known about 500 belongs to, and more than 4500 plant, wherein, fruits and vegetables class is harmful to the monoid of trypetid up to 15 Category, 22 subgenus, more than 150 are planted, and [Bactrocera dorsalis (Hendel)], melonfly are closed with dacus dorsalis in China [Bactrocera cucurbitae (Coqil Lett)], citrus fruit fly [Bactrocera minax (Enderlein)] etc. It is relatively conventional, it is distributed mainly on Hunan, Hubei, Sichuan, Chongqing, Guizhou, Fujian, Guangdong, Guangxi, Hainan, Yunnan, Taiwan etc. Save.The host range of harmful trypetid is very wide, is related to economic fruit class plant and amounts to 24 sections, 42 categories:4 section of vegetable plants, 16 Belong to (wild host plant is not included).Fruit fly reproductive capacity is strong, harmfulness is big.In trypetid distribution or Endemic Area, post Main fruit percentage of injury average out to 25-45%, up to 80% when serious, or even total crop failure, bring great economy to fruits and vegetables class crop Loss, has seriously affected peasant and has increased production extra earning.
At present, the method for preventing Fruit fly mainly has cultural control, chemical prevention, physical control and biological control Deng.Wherein cultural control turns over the pupa that goes out etc. including periodically removing the real band wormed fruit in plantation, fruit bagging and winter;Chemistry is anti- Control measure and mainly spray Bait on Killing trypetid;Physical control measure uses the technology that trypetid trapping bait and poison bait are combined, mesh Before, the trapping bait for preventing trypetid is mainly chemical synthesis trapping bait, such as lures ketone (cue lure), methyl eugenol (methyleugenol) etc..Since cultural control measure is time consuming, effect is bad;Chemical prevention not only easily produces trypetid The problem of giving birth to the resistance to the action of a drug, and people, animal be harmful to, are also easy to produce the environmental pollutions such as pesticide residue;Property trapping bait in practical applications There is the problems such as volatilization is fast, the lasting period is short, medication is frequent again, do not reach the prevention purpose of control borer fruit rate, and apply at present Most extensive trapping bait methyl eugenol only lures male worm etc., its application is restricted.
There are sugar-vinegar liquid, female hormone, protein three major types lure for trypetid both at home and abroad.Sugar-vinegar liquid is time-consuming, laborious, cost It is higher;Female hormone can only lure male worm, and since male worm energy manages it multiple mating, preventive effect is often not ideal;Protein-based trapping bait can To lure female male worm, effect is good.But the protein lure on current overseas market is pure animal protein, production cost is high.
Americal rice leaf miner (Liriomyza sativae Blanchard) falls within Diptera Agromyzidae (Agromyzidae) Liriomyza (Liriomyza), is commonly called as vegetable leafminer, map worm, scrawly handwriting etc., is that leaf mining is caused harm Dangerous pest.China finds most earlier than in December, 1993 first in Hainan Province Sanya, and subsequent Americal rice leaf miner is gradually northwards Diffusion, occurs, is broken out in Shandong, Beijing within 1996 in Kunming, Yunnan occurring and damage, nineteen ninety-five for 1994 on Shanghai and Nanjing and other places Cause disaster, occur in Henan, Shanxi within 1997, cause disaster in northeast, the Inner Mongol within 1998, in addition to Tibet, the whole nation is distributed.It Host plant up to more than 200 is planted, and wherein vegetables are aggrieved with solanaceous vegetables (except pimento, capsicum), beans, melon, Carrot family etc. It is most heavy.
Adult of Liriomyza Sativae Blanchard is small-sized flies, body black, and body grows 1.3~2.3 millimeters, 8.7~12.6 days service lifes, per female 70~125 pieces of all one's life oviposition, incubation rate is up to more than 90%.Larva milky is to faint yellow, long 3 millimeters, year breeding 15 ~20 generations.Winter enters in heliogreenhouse, can endanger in the four seasons, mainly there is 2 hazard booms, respectively appear in 5~June and 9~ In October, year is from generation to generation up to 20 more than generation.Adult, larva can endanger, female adult pest acanthopore and feeding wherein in host's blade And oviposition, larva potential food mesophyll or petiole after blade table is subcutaneously hatched, irregular snakelike white gallery is produced, destroys blade Chlorophyll, influences photosynthesis, and the withered and yellow even whole strain that comes off of blade is withered when serious;Seedling stage causes to ruin seedling.Endanger serious field Aggrieved strain 100%, blade aggrieved 70%.Phase cucurbita pepo is abounded with, after finding to endanger, mesophyll is suffered all within 7 days or so, ruins within 15 days or so Go out.Larva and adult can also propagate some virosis by feeding.
At present, with the change of cropping system, the continuous expansion of warm winter phenomenon and open country and vegetable at protected field area is continued, Liriomyza has become endangers one of especially big, exceptionally poverty-stricken difficult disastrous pest of prevention in various vegetables, whole year occurs more from generation to generation and weighs Folded confusion, its spread in china is fast, and the annual generation of crop field the end of spring and the beginning of summer autumn protecting field is especially serious.The Protectorate cultivation of vegetables is vegetable Dish liriomyza bryoniae provides good hibernacle.The worm not only can be overwintering in greenhouse, and can in canopy occurrence injury, become The important worm sources in outdoor vegetable field.Therefore, doing the prevention in greenhouse well can effectively prevent the worm after canopy is taken off to outdoor vegetable Diffusion harm.
Because the worm generation overlap phenomenon is serious, the resistance to the action of a drug is strong, more difficult prevention in production.At present, dive in production to America spot The prevention of fly is still mainly based on chemical prevention, in order to solve the food-safety problem that chemical pesticide for many years is brought, Ying Li Insect pest is controlled with bio-control method, but benefit is not also really applied and played to biological prevention in production, finds With strong points, preventive effect is high, and to people, animal safety, it is extremely urgent without a kind of new lure of environmental pollution.
