A kind of termite-killing trapping medicament and preparation method
Technical field
The present invention relates to termite control field, be specifically related to a kind of attracticide and preparation method of control termites.
Background technology
Termite, as global insect, relates to the various aspects such as building construction, farm-forestry crop, reservoir dam, storage goods and materials, underground cables to the loss that national economy causes.All there is termite damage most province ,city and area of China, endangers more serious more southward.Along with the quickening of mankind's town and country construction, Material Transportation are more frequent and the impact of the factor such as climate warming, termite damage is day by day serious and extensively paid attention to by people, actively develops preventing and controlling and effectively can alleviate loss because termite damage causes.
For a long time, termite control uses high poison and the great insecticide of environmental pollution mostly, as Niran, mirex, aldrin, dieldrin, heptachlor etc.Although these medical treatment effects are very remarkable, the chemical substance long-term existence of a large amount of high malicious high residue, in environment, has great potential risk to people and animals, and termite swarming being entered to building is also helpless.Along with China fulfils " Convention of Stockholm " comprehensively, termite control is eliminated the medicament of high malicious high residue gradually and is actively found substitute products.
The termiticides that current China uses mainly contains chlopyrifos, sumicidin, decis, Biphenthrin, cypermethrin, permethrin, Imidacloprid, ethiprole, Hydramethylnon Bait, HEXAFLUMURON, vikane etc.Go out bait formulation, paste, the Er slice of controlling use of termite is input, and the former medicine of vikane is used for the airtight stifling of the stifling of odontoterme the ants main way and building ant evil, pulvis for spreading in building and timber.The application process of the formulation medicament such as suspending agent, missible oil, microemulsion, aqueous emulsion, water dispersible granules agent of termite prevention has the immersion of soil treatment (sprinkling), timber, sprays and smear etc.
Although toxicity is lower comparatively speaking, residual life is shorter for surrogate-data technique, long-term a large amount of use is still to environment and the human health particularly larger hidden danger of groundwater environment existence.Trapping system (Monitoring and Controlling technology) is because its low toxicity, dosage are few and can effectively control termite damage and be widely used gradually, its principle utilizes the material of termite eating to make bait, take after the worker ant of looking for food of some is lured dust spraying or throw in poison bait, after returning nest group with malicious termite, transmit mutually by trophallaxis and grooming behavior the effect finally reaching and kill whole nest termite.Trapping system greatly reduces the usage amount of chemical agent, meets the target of Ecological Civilization Construction, will promote the upgrading of China's termite control technology and theory.But in actual applications, still there is following problem:
(1) first lure collection termite to dust again, spray or throw in poison bait, need running check whether to lure to collect to arrive sufficient amount
Termite, can greatly increase cost of labor and cause interference to termite foraging activity, affect gathering effect;
