Embodiment 1

[0020] The collection of embodiment 1 plant volatile substances

[0021] Steam distillation: refers to the co-distillation of plants and water, so that the volatile products and water vapor are distilled together, and the synergist is separated by condensation.

Embodiment 2

[0022] Embodiment 2 field biological activity determination test

[0023] Lure preparation:

[0024] (1) The lure carrier adopts a cylindrical green concave rubber plug with a height of 14mm, an inner diameter of the opening end of 8mm, a wall thickness of the opening end of 1mm, and an opening depth of 5mm.

[0025] (2) The sex pheromone components of cutworm cis-7-dodecyl acetate (Z7-12:Ac), cis-9-tetradecyl acetate (Z9-14:Ac) and cis-11- Hexadecyl acetate (Z11-16:Ac) was mixed at a mass ratio of 3:1.3:0.8, and diluted with n-hexane to a solution with a concentration of 1 μg / μL.

[0026] (3) Dilute one or more synergists including 2-phenylethyl alcohol, ethyl benzoate and benzyl acetate with n-hexane to a solution with a concentration of 0.1 μg / μL.

[0027] Aspirate the solution and let the solvent evaporate.

[0028] Before the test, the lures were placed in a -20°C refrigerator for use.

Abstract

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.

Description

technical field [0001] The invention belongs to the technical field of biological control, and in particular relates to an attractant composition for preventing and controlling cutworms and an application thereof. Background technique [0002] Agrotis ypsilon (Rottemberg), belonging to Lepidoptera and Noctuidae, is the main underground pest of vegetable seedlings and one of the worldwide agricultural pests. It is mainly harmful to various crops, such as cruciferous, leguminous, solanaceous, cucurbitaceous, spinach and other vegetables, as well as more than 100 crops such as peanuts and tobacco. Its larvae can bite off the stems of crop seedlings close to the ground, causing the death of the whole plant, causing lack of seedlings, broken ridges, and even destruction of seeds. Adults are typical migratory pests, which can cause damage in various places along with wind fields and airflows. At present, the methods of its control mainly include spraying chemical agents, lamp lur...
