The invention discloses an attractant composition for preventing and controlling agrotis ypsilon and application thereof. The attractant composition comprises agrotis ypsilon sex pheromone and synergist in a mass ratio of 1:0.1, wherein the main ingredient of the agrotis ypsilon sex pheromone is cis-7-dodecenyl acetate, cis-9-tetradecyl acetate and cis-11-hexadecyl acetate, and the synergist is selected from one or more of 2-phenethyl alcohol, ethyl benzoate and benzyl acetate. The attractant composition can be used for effectively attracting and killing male worms of agrotis ypsilon, reducing the reproductive rate and gradually controlling extinction of pest population, so that the aim of preventing and controlling pests can be achieved. The attractant has small dosage, is environmentally friendly, can be accurately applied to insect condition prediction, mass trapping and mating disruption, and has an important meaning for comprehensive control of agrotis ypsilon.

The invention particularly relates to an indoor pest catching device realizing intelligent reminding. The indoor pest catching device comprises an arch-shaped pest adhering plate, a planar pest adhering plate and an attracting core; two rows of straight-tooth-shaped inserting blocks are arranged on the two straight sides of the arch-shaped pest adhering plate respectively, bevels used for clampingare arranged at the ends of the straight-tooth-shaped inserting blocks, two rows of rectangular inserting holes are formed in the two opposite sides of the planar pest adhering plate respectively, the straight-tooth-shaped inserting blocks are inserted into the rectangular inserting holes, and the arch-shaped pest adhering plate and the planar pest adhering plate are inserted and installed to from an arch-house-shaped attracting bin with opposite openings; the attracting core is arranged in the arch-house-shaped attracting bin. The indoor pest catching device realizing intelligent reminding has the advantages of being low in cost, scientific in design, simple in structure, easy and convenient to operate, convenient to use, good in adaptability and high in practicability.

The invention discloses a sex attractant for controlling mythimna separata and application thereof. A medicinal component of the sex attractant for controlling the mythimna separata comprises cis-11-hexadecenal and cis-11-hexadecene acetate according to a weight ratio of 96:4, and further comprises cis-9-hexadecenal, wherein the weight ratio of components of the cis-11-hexadecenal, the cis-11-hexadecene acetate and the cis-9-hexadecenal in the medicinal component is 96:4:(0.5-5). The sex attractant can be applied to dynamic monitoring and control of a mythimna separata population; by such a monitoring method, the nature of a migratory insect source can be clearly determined; the monitoring method has the superiority that cannot be achieved by other monitoring methods; during application tothe control, the using amount of a chemical pesticide can be saved, natural enemies are not killed, the environment is not polluted, the ecological balance is not destroyed, and promotion of sustainable control of the mythimna separata in China is facilitated.

The invention provides a sex pheromone for controlling phauda flammans walker and a preparation method of a sex pheromone lure. The sex pheromone for controlling the phauda flammans walker is preparedfrom cis-9-hexadecenal and (Z,Z,Z)-9,12,15-octadecatrienal in a mass ratio being 1:1. The preparation method of the sex pheromone lure comprises following steps: firstly, 10 microlitres of cis-9-hexadecenal and 10 microlitres of (Z,Z,Z)-9,12,15-octadecatrienal are blended in 980 microlitres of a hexane liquor at room temperature, and a mixed liquor with the mass ratio of the two sex pheromones being 1:1 is obtained; then the mixed liquor containing the sex pheromone for controlling the phauda flammans walker is dropwise added to a cotton sliver lure, and after n-hexane in the mixed liquor containing the sex pheromone for controlling the phauda flammans walker is volatilized, the lure containing a phauda flammans walker luring agent is prepared; finally, the prepared lure is sealed in aluminum foil and refrigerated at subzero 20 DEG C. The sex pheromone for controlling the phauda flammans walker is high in specificity, has obvious trapping effect on the phauda flammans walker outdoorsand is stable in effect.

The invention discloses a pheromone composition for Mamestra brassicae and application of the pheromone composition. The pheromone composition for the Mamestra brassicae comprises Mamestra brassicae sex pheromones and synergists, wherein the weight ratio of the Mamestra brassicae sex pheromones to the synergists is 1: (0.5 to 2.5), cis-11-hexadecene acetate, cis-11-heptadecene acetate and hexadecyl acetate serve as main ingredients of the Mamestra brassicae sex pheromones, and the synergists comprise one or more of terpinene, eudesmol, camphor and chrysanthenone. The pheromone composition for the Mamestra brassicae, provided by the invention, can be accurately applied to the insect pest situation measuring and reporting, mass trapping and mating interference of the Mamestra brassicae and has an important significance in the comprehensive treatment of the Mamestra brassicae.
