Problems solved by technology

[0003] At present, the main components of sex attractants for cabbage armyworm are cis-11-hexadecene acetate, cis-11-heptadecene acetate and hexadecene acetate, and the trapping effect is ideal, but Due to the low persistence, resulting in high replacement costs, it is difficult to popularize

Embodiment 1

[0025] Embodiment 1 The preparation of cabbage armyworm sex attractant composition lure core

[0026] Mix the sex pheromone of cabbage spodoptera and solvent (n-hexane) and drop it into the lure of the anti-mouth rubber head. In the lure, dichloromethane is added dropwise after the n-hexane volatilizes completely, and after the dichloromethane volatilizes completely, the cabbage spodoptera sex attractant composition lure is made. In order to ensure the release effect, 500-3500 μg of cabbage moth sex attractant was placed in each rubber lure core, and the average distance between traps was more than 10m. Select the contiguous cabbage field with the same cabbage variety, growth, fertilizer and water management conditions, an area of ​​more than 20 mu, and severe occurrence of cabbage armyworm as the experimental field. Set up 5 replicates for each treatment, and place the above-mentioned sex-attractant-containing barrels evenly and randomly. type trap. After placement, the num...

Abstract

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.

Description

technical field [0001] The invention belongs to the technical field of insect sex pheromone preparation, and in particular relates to a sex attractant composition of cabbage armyworm and its application. Background technique [0002] Cabbage moth (Mamestra brassicae Linnaeus) belongs to Lepidoptera Noctuidae and is a major vegetable pest with a wide distribution range. It mainly harms the leaves of crops with larvae, eats the leaves, pollutes the leaf balls, and brings huge economic losses to agricultural production in severe cases. Spodoptera cabbage has strong fecundity, and the chemical agents known to have good control effects on it are mostly organochlorine pesticides that are banned from production, and Spodoptera cabbage has developed resistance to many chemical agents to varying degrees. Long-term use of chemical agents to control cabbage armyworm may pollute the environment, destroy natural enemies and ecosystems, and the control effect is unstable. According to t...
