Description
Technical field
The present invention relates to a kind of ointment of preventing and treating poplar longicorn insect pest, belong to agricultural chemicals and formulation art thereof.
Background technology
Poplar longicorn is the important trunk borer of the seeds such as China poplar, willow, elm, maple, and the poplar longicorn of having reported in China reaches kind more than 100.Because poplar longicorn life is hidden, Natural Enemies is few, the history of life is complicated, and willow is China's afforestation, checks winds and fixes drifting sand and one of the first-selected seeds of the afforestation such as fast growing, cause poplar longicorn food resource sufficient, in China's poplar longicorn harm seriously, year generation area is at 600,000 hm
2left and right.Over 10 years, yellow spotted star longicorn beetle, anoplophora glabripennis rapid spread, harm is serious, and the development of willow is extremely restricted, and has had a strong impact on forestry sound development.Because the life of poplar longicorn larva is hidden, to preventing and controlling, brought very large difficulty, so the control of poplar longicorn is an instant task.What the control of poplar longicorn adopted at present is the strategy of integrated control.Concrete condition is as follows:
(1) Silvicultural Measures: select to have the improved seeds afforestation such as middle forest 46, middle forest No. 108 of pest-resistant performance, strict nursery stock quarantine, avoids being with worm nursery stock afforestation.Newly make poplar forest away from worm seedbed, or the isolation strip of planting, Mixed Forests; With seeds and mixed friendship of willow collocation of longicorn apocleisis, afforest, generally with Mixed in blocks, be advisable, shelter belt can adopt section gap to mix and hand over.Adopt the measures such as large cave, seedlings, flood, duty are applied fertilizer, duty is loosened the soil, promote the healthy Fast Growth of forest, strengthen insect resistance capacity.
(2) biological control measure: adopt the controls such as longicorn natural enemy insect, longicorn causal organism, can control longicorn insect population with woodpecker in conditional region; New planting site can be had a liking for longicorn the moraceae plants etc. of food, trapping longicorn adult.Also having the bio-control method for longicorn individuality is mainly to adopt the directly stifled longicorn defecation hole that is coated with of the biologic products such as white muscardine fungi, green muscardine fungus, bacillus thuringiensis,Bt.
(3) physical measure: mulberry longicorn nocturnalism, has stronger phototaxis, available black light lamps.Anoplophora glabripennis is all movable round the clock, and phototaxis is not strong, can artificial capture method adult.With trunk, be coated with from avoiding and keep away longicorn Adult worms producting eggs, can repair deinsectization branch winter in conjunction with tending [after young plantation, cuts for the trees that are seriously injured, and eradicates hidden danger.
(4) chemical measure: 1. the organophosphorus insecticide such as available zinc phosphide is made poison and signed, and inserts worm channel, smoked kill larva, effect can reach 90%.2. with 50～300 times of organophosphorous pesticide dilution injection worm channels, kill larva.3. with systemics agricultural chemicals such as nuvacron, flolimats, at butt or root punching, inject, after perfusion, with wet soil, seal, can prevent and treat tall and big trees larva.4. in adult stage and ovum phase, large area is sprayed 1000 ~ 2000 times of glue suspensions of young urea that go out, and can kill adult and ovum.5. use novel contact insecticide " green prestige thunder " control longicorn adult.
The difficult problem that each method faces is above that biological control effect is unstable, and control efficiency is subject to the impact of the factors such as weather, and poplar longicorn is as a kind of borer pest, and biological control medicament is difficult to arrive adult and the larva of longicorn; What still use in large area at present, be chemical prevention and control method, as adopted, poison is signed, boring injection, bury the methods such as medicine, spraying, but these methods run into very hang-up on control efficiency or concrete implementation and operation.Poison label method need to find the hole of roundheaded borer and adult, and during large area control, workload is too large; Boring while being injected at large area control workload too large, and bore the xylem that injures willow after sky, the self-healing ability of willow is limited, very major part there will be rotten random situation, peasant is accepting in the method, there is certain difficulty; During spraying, dosage is large, and droplet can need to be employed high pressure spraying mechanical with wind drift, and medicament is also difficult to effectively arrive polypide, and medicament availability is too low.
