Embodiment 1

[0029] Example 1: cis-7-hexadecenal (sex pheromone component 1, referred to as component 1) and the organic solvent n-hexane in a weight ratio of 1:6548 were prepared as a sex attractant for the double-appointed moth to be tested;

Embodiment 2

[0030] Example 2: cis-9-tetradecenol (sex pheromone component 2, referred to as component 2) and the organic solvent n-hexane in a weight ratio of 1:6548 were prepared as a sex attractant for the double-headed moth to be tested;

Embodiment 3

[0031] Example 3: cis-11-tetradecene acetate (sex pheromone component 3, referred to as component 3) and the organic solvent n-hexane in a weight ratio of 1:6548 were prepared as a sex attractant for the double-headed moth to be tested;

Abstract

The invention relates to the field of biotechnology, in particular to a sex attractant for the bicamerid moth and its preparation method and application. Contains sex pheromone components and solvents of Spodoptera females. The female sex pheromone components of Spodoptera include cis-7-hexadecenal, cis-9-tetradecenol and cis-11-tetradecenyl acetate. Whether the sex attractant of Spodoptera exigua according to the present invention is used to predict the situation of insects or to trap Spodoptera exigua, the effect is remarkable, and it is harmless to natural enemies, humans, animals and the environment, and it can also reduce the amount of Spodoptera exigua. The use of chemical pesticides in moth control is conducive to the protection of the ecological environment and the realization of the goal of zero growth in the use of pesticides in pest control, and has good ecological, social and economic benefits.

Description

technical field [0001] The invention relates to the field of biotechnology, in particular to a sex attractant for the bicamerid moth and its preparation method and application. Background technique [0002] Spodoptera bicameralis Athetis dissimilis (Hampson) is an important lepidopteran pest that has occurred in summer corn fields after the reform of crop farming methods in my country in recent years. . Since it was first discovered in Shandong Province of my country in 2012, its damage range has expanded year by year, and it is currently found in Henan, Shaanxi, Anhui and other places in my country. When damaging corn, the larvae of Spodoptera spp. mainly hide in the field litter, under spontaneous wheat seedlings or weeds to feed on the stem base of corn seedlings. In severe cases, corn seedlings are missing and ridges are broken, and replanting is required. Compared with the corn pest that occurred in the past few years - Spodoptera exigua, its larvae eat more food and ...
