Active composition based on linalool and caryophyllene, argyrogramma agnata attractant, lure and application thereof

Abstract

The invention relates to the technical field of pest control, and provides an active composition based on linalool and caryophyllene, an argyrogramma agnata attractant, a lure and application thereof.The active composition provided by the invention comprises the following components in parts by weight: 20-45 parts of linalool, 1-15 parts of the caryophyllene, 15-35 parts of phenylacetaldehyde, 2-20 parts of benzyl acetate and 10-30 parts of salicylaldehyde. The active composition provided by the invention can lure female moths and male moths at the same time, can be used for trapping and killing a large number of moths, can significantly reduce the number of adult argyrogramma agnata in the field, and reduces the population density of offspring insects. The argyrogramma agnata attractantprovided by the invention is strong in specificity, does not generate resistance, does not harm natural enemies, is non-toxic to human and livestock, and is environment-friendly; the argyrogramma agnata attractant is high in stress resistance, resistant to wind, rain and sunlight and long in lasting period. The argyrogramma agnata attractant and the lure provided by the invention can be applied toargyrogramma agnata prediction and forecast, and the insect trapping amount can accurately predict the population occurrence dynamics of the argyrogramma agnata.

Description

technical field [0001] The invention relates to the technical field of pest control, in particular to an active composition based on linalool and caryophyllene, an attractant for silver-leaved armyworm, a lure core and applications thereof. Background technique [0002] Silver print moth is an insect of Lepidoptera and Noctuidae. It is a polyphagous pest and hosts cruciferous vegetables such as rapeseed, cabbage, cauliflower, cabbage, radish, bean crops, kaba, eggplant and other crops. Silver leaf moth has 1 to 5 generations a year, survives the winter as pupae, and emerges at night as adults. It has strong phototaxis and weak chemotaxis, so it is difficult to control. Traditionally, chemical pesticides are used for prevention and control, but chemical pesticides will pollute the environment, cause pesticide residues, cause pest resistance, kill natural enemies and many other problems.

AI Technical Summary

Problems solved by technology

Silver leaf moth produces 1 to 5 generations a year, overwinters as pupae, and emerges at night as adults, with strong phototaxis and weak chemotaxis, so it is difficult to control

Traditionally, chemical pesticides are mostly used for control, but chemical pesticides will pollute the environment, cause pesticide residues, cause pest resistance, kill natural enemies and many other problems

[0003] The sex lure is an attractant made from the sex pheromone of the silver leaf moth, which has the advantages of strong selectivity, trace efficiency, and environmental friendliness, but it can only trap and kill male individuals of the same species, and the population density of wild female moths is relatively high. can not achieve the desired effect

[0004] Floral-scented attractants are made by utilizing moths' selective tendency to floral scents and using a variety of active ingredients. short
