Background technology:
Poplar longicorn is the important trunk borer of seeds such as China poplar, willow, elm, maple, and the poplar longicorn of having reported in China reaches kind more than 100.Because the poplar longicorn life is hidden, the natural enemy kind 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 afforestation such as fast growing, cause poplar longicorn food resource abundance, in China's poplar longicorn harm seriously, year generation area is at 600,000 hm
2About.Over 10 years, yellow spotted star longicorn beetle, anoplophora glabripennis rapid spread, harm is serious, makes the development of willow be subjected to very big restriction, has had a strong impact on the forestry sound development.Because the life of poplar longicorn larva is hidden, brought very big difficulty to preventing and controlling, so the control of poplar longicorn is an instant task.
What the control of poplar longicorn was adopted at present is the strategy of integrated control.Concrete condition is as follows:
1. forest culture and management measure: 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 the worm seedbed, or the isolation strip of planting, build mixed forest; Mix with the seeds of longicorn apocleisis and willow collocation and to hand over afforestation, generally be mixed with suitablely with bulk, shelter belt can be adopted section gap to mix and be handed over.Adopt measures such as big cave, seedlings, big flood, duty are applied fertilizer, duty is loosened the soil, promote healthy quick growth of forest, the enhancing insect resistance capacity.
2. biological control measure: adopt controls such as longicorn natural enemy insect, longicorn causal organism, can control the longicorn insect population with woodpecker in the conditional region; New planting site can be had a liking for the moraceae plants etc. of food, trapping longicorn adult with longicorn.It mainly is to adopt the directly stifled longicorn defecation hole that is coated with of white muscardine fungi, green muscardine fungus, bacillus thuringiensis,Bt biologic products such as (Bt) that bio-control method at the longicorn individuality is also arranged.
3. physical measure: mulberry longicorn nocturnalism has stronger phototaxis, available black light lamp trapping.Anoplophora glabripennis is all movable round the clock, and phototaxis is not strong, can manually catch adult.Be coated with from avoiding with trunk and keep away the longicorn adult and lay eggs, can repair the deinsectization branch winter in conjunction with tending [after young plantation, cuts the generation trees that seriously are injured, and eradicates hidden danger.
4. chemical measure: 1. organophosphorus insecticide such as available zinc phosphide is made poison and is signed, and inserts worm channel, the smoked kill larva, and effect can reach 90%.2. with 50-300 times of organophosphorous pesticide dilution injection worm channel, kill larva.3. inject at butt or root punching with systemics agricultural chemicals such as nuvacron, flolimats, seal with wet soil the perfusion back, can prevent and treat tall and big trees larva.4. in adult stage and ovum phase, large tracts of land is sprayed the young urea 1000-2000 times glue suspension that goes out, and can kill adult and ovum.5. use novel contact insecticide " green prestige thunder " control longicorn adult.
More than a difficult problem that each method faced be biological control effect instability, control efficiency is subjected to the influence of factors such as weather, and poplar longicorn is as a kind of borer pest, the biological control medicament is difficult to arrive adult and the larva of longicorn; What still use in large tracts of land at present is chemical prevention and control method, as adopts that poison is signed, the boring injection, buries 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 find the hole of roundheaded borer and adult, and during large area control, workload is too big; Workload was too big when boring was injected at large area control, and injured the xylem of willow behind the brill sky, and the self-healing ability of willow is limited, and rotten random situation appears in very most of meeting, and the peasant has certain difficulty on reception the method; Dosage is big during spraying, and droplet can need be employed the high pressure spraying mechanical with wind drift, and medicament also is difficult to effectively arrive polypide, and the medicament availability is too low.
Summary of the invention
The object of the invention provides that a kind of lasting period is long, and environmental pollution is little, the ointment of the control woody plant insect that dispenser is easy.
The present invention realizes that the technical scheme of above-mentioned purpose is: by active ingredient Acetamiprid percentage by weight is 1.0-10%%, and carbosulfan or orthene percentage by weight are 1.0-50%, and all the other are that additive mixture forms.
Selected Acetamiprid, orthene and the carbosulfan of the present invention has good systemic action, synergistic effect was obvious after Acetamiprid and orthene or carbosulfan were mixed, the paste of being made is coated in the band girdle place of trunk, medicament has good translocation and reaches the position that insect is caused harm at phloem, the borer pest position of causing harm particularly, simultaneously trunk band girdle place coat have in the medicament of suction and tagging property, can stop insect from the creeping back and forth of trunk bottom and trunk top, significantly reduce the chance that causes harm.
Above-mentioned auxiliary agent is: solvent, sticker and filler, the auxiliary agent weight percentage is as follows in the paste: solvent 2.0-70.0%, sticker 1.0-20.0%, filler 10.0-80.0%.
Preparation paste solvent for use is selected from following one or more: benzene,toluene,xylene, methyl alcohol, ethanol, propyl alcohol, butanols, isobutanol, cyclohexanone, MEK, isophorone, pyrrolidones, N-Methyl pyrrolidone, dimethyl formamide, methyl-sulfoxide, 2-Pyrrolidone, cyclohexanone.
Preparation paste used sticker is selected from following one or more: poly-ethyl acetate, gelatin, polyvinyl alcohol, styrene-butadiene latex, gum Arabic, sodium alginate, xanthans, sodium carboxymethylcellulose, carboxy-propyl cellulose sodium, polyethylene glycol, polyethylene glycol oxide, polyvinylpyrrolidone, polyacrylamide, soluble starch, dextrin, polyvinyl acetate, coumarone resin, Petropols, naphthols-formaldehyde resin.
Preparation paste used filler is to be selected from following one or more: diatomite, Concave-convex clay rod, bentonite, sepiolite, kaolin, potter's clay, precipitated calcium carbonate, sawdust powder, rice husk, tobacco powder, walnut parting, lignin, white carbon.
Ointment of the present invention is made with conventional method, will have after absorption Acetamiprid and orthene or carbosulfan be mixed according to aforementioned proportion in good, adds solvent, sticker, filler in proportion, and canned moulding.Before use, utilize homemade band girdle cutter at willow trunk 0.3-1.8 rice from top to bottom around the about 2-20 of trunk spiral strip off one width centimetre groove, the phloem of only cutting open during cutting, and do not injure xylem, spill xylem (width of strip off bark and play up and down 2 vertical ranges change) because of the vary in diameter of tree, be coated with at strip off bark place and spread the ointment of being made, allow medicament be transmitted to the position that insect is caused harm by the phloem of tree, it is long that this medicament has the lasting period, environmental pollution is little, this is easy and simple to handle simultaneously, only need gently strip off bark once, made ointment is coated in strip off place by the extruding tanning device gets final product, strip off bark and coating can carry out continuously.Simultaneously the ointment that uses of strip off place has very strong action of contace poison, forms the obstruct of certain width up and down between back and forth at trunk, when insect creeps on trunk, can be killed behind the contact ointment, has significantly reduced insect the causing harm to plant of creeping.
