Description
Technical field
The present invention relates to pesticide field, more specifically relate to a kind of preparation method of fruit fly sexual attraction slow-release formulation.
Background technology
The trypetid class pest belongs to diptera (Diptera), Tephritidae (Tephritidae), is the one type of important pests that fruits and vegetables class crop is caused heavy losses.Tephritidae known up to now about 500 belongs to; Kind surplus in the of 4500, wherein, the monoid of the harmful trypetid of fruits and vegetables class reaches 15 genus, 22 subgenus, kind surplus in the of 150; China is with dacus dorsalis; Melon trypetid, citrus fruit fly etc. are comparatively common, mainly are distributed in 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 plant and amounts to 24 sections, 42 genus: greengrocery plant 4 sections, 16 belong to (wild host plant not included).Trypetid class pest fertility is strong, harmfulness is big.Distribute or popular district trypetid, host's fruit rate of damage average out to 25-45%, when serious up to 80%, even total crop failure.Compare with chemical pesticide, insect sex pheromone has selectivity strong, nontoxic, not killed natural enemies, advantage such as free from environmental pollution, both at home and abroad to the research of insect sex pheromone for a long time.Adopting lure trapping adult is a kind of trypetid control mode of environment-friendly and green; For citrus fruit fly and melon trypetid; Mainly be to add a certain amount of poisonous substance, be contained in to lure and trap and kill male worm in the bottle with sex attractant methyl eugenol (Methyl eugenol) or cue-lure (Cuelure).
There are problems such as volatilization is fast, the lasting period is short, medication is frequent again in sex attractant in practical application, does not reach the purpose of preventing and treating of control borer fruit rate.And compare with the conventional pesticide formulation, sustained release agent have the lasting period long, pesticide efficacy is high, stable characteristics such as rate of release are run off, have in the decomposition that can reduce or avoid agricultural chemicals to cause because of external environment.
Summary of the invention
The object of the invention is in order to overcome problem and the shortcoming that above-mentioned conventional pesticide formulation exists; Utilize the advantage of sustained release agent; And a kind of preparation method of fruit fly sexual attraction slow-release formulation is provided; The present invention is wrapped in fruit fly pheromones and toxic component in the polymeric membrane of polyalcohol and the generation of isocyanates polymerisation, has reached the effect that sex pheromone and toxic component slowly discharge, and in field trial, shows very long lasting period and good trapping effect.
Technical scheme of the present invention is:
A kind of preparation method of fruit fly sexual attraction slow-release formulation; By weight; Carry out according to the following steps: (1), be dissolved in 100 parts of organic solvents methyl eugenol of 1-50 part or the toxic component of cue-lure and 0.1-20 part subsequent use; Organic solvent is the conventional organic solvent that uses, and wherein toxic component is chlorophos, AVM, Affirm (Merck Co.) or chlopyrifos; (2), with 1000 parts of polyalcohols of molecular weight＜3000 be-stirred 15-100 minute under the 0.1MPa condition at 35 ℃-75 ℃, vacuum; (3), the stock solution with step (1) joins in the polyalcohol of step (2); And continue to stir until evenly; Add 3000-10000 part isocyanates again; And at 35 ℃-75 ℃, vacuum be-continue to stir 120 minutes under the 0.1MPa, stop to vacuumize, obtain the fruit fly sexual attraction slow-release formulation of paste.
Described polyalcohol is polybutadiene, end hydroxy polyether resin or hydroxyl telechelic polyester resin.
Described isocyanates is toluene di-isocyanate(TDI), hexamethylene vulcabond or polymeric rings hexamethylene diisocyanate.
Polyalcohol of the present invention and isocyanates react and generate a kind of polymeric membrane; The sex pheromone and the toxic component of methyl eugenol or cue-lure are wrapped in having in the infiltrative polymeric membrane of polyalcohol and isocyanate reaction gained; Reached the effect that sex pheromone and toxic component slowly discharge, in field trial, shown the very long lasting period and well lure the collection effect.The fruit fly sexual attraction slow-release formulation of the present invention's preparation is mainly used in monitoring fruit fly population density or the anti-governance of large-area fruit fly insect system.
