The invention relates to a plutella xylostella attractant and a preparation method of the plutella xylostella attractant. The plutella xylostella attractant is prepared by the steps of: dissolving alpha-pinene, beta-pinene, geraniolene, cineole, cis-3-hexenyl acetate, isothiocyanate, cis-11-hexadecene aldehyde, cis-11-hexadecene acetate, cis-11-hexadecene alcohol and cis-9-tetradecene acetate in acetic ether and ethanol in formula ratio; and mixing the mixture with sodium dodecyl benzene sulfonate and water in formula ratio. The attractant which is efficient for plutella xylostella is researched and developed by combining the latest research result that the olfactory receptor system of plutella xylostella receives external information according to characteristics that plutella xylostella positions host plants by volatile substances derived from the host plants and positions heterosexual mates by sex pheromone. The attractant is put on the market, and a plutella xylostella preventing and treating product which is safe, environment-friendly and efficient can be provided for farmers.

The invention discloses a lygus pratensis linnaeus host plant volatile matter, which includes any mixture of one or more of nonanal, farnesene, ALPHA-pinene, 1-caryophyllene and cis-3-hexenyl acetate.The invention also discloses application of the lygus pratensis linnaeus host plant volatile matter in preparing a lygus pratensis linnaeus attractant and preventing and controlling the lygus pratensis linnaeus. The lygus pratensis linnaeus host plant volatile matter is studied from the aspects of electrophysiology and behaviors, and it is proved that the nonanal, the farnesene, the ALPHA-pinene,1-caryophyllene and the cis-3-hexenyl acetate have the attracting action to the lygus pratensis linnaeus, wherein the attracting ratio of the nonanal reaches up to 66.7 percent. The lygus pratensis linnaeus host plant volatile matter provided by the invention is a potential candidate component of an approaching-avoidance agent or the attractant, can be used for designing a lygus pratensis linnaeus approach behavior regulating agent to be used for forecasting, preventing and controlling the lygus pratensis linnaeus, and thus effectively preventing the lygus pratensis linnaeus from causing disasters to agriculture and animal husbandry in China.

The invention discloses a composition for attracting adult curculio chinensis. The composition comprises the following components in parts by volume: honeysuckle essential oil, andrographis essentialoil, cis-3-hexen-1-ol, cis-3-hexenyl acetate, 3-heptanone, hexanal and nonanal. The preparation method of the composition comprises the following steps: A, preparing an organic matter mixed solution;B, dissolving gelatin and gum arabic to prepare a coating solution; C, adding the coating solution into the organic matter mixed solution under the stirring condition, and uniformly mixing; D, coagulating and solidifying to prepare a slow-release composition; and under the stirring condition, adding acetic acid into the mixed solution prepared in the step C to adjust the pH value of the mixed solution to be 3.8-4, and coagulating the mixed solution to prepare a composition with a slow release effect. The adult curculio chinensis is attracted pertinently, and the damage of the curculio chinensis in an oil tea garden can be effectively prevented and controlled in cooperation with the corresponding insect catcher. Meanwhile, organic solvents and chemical pesticides are not used, and the negative influence on the ecology and the environment of the oil tea garden is small.
