Embodiment 1

[0010] A conventional PVC capillary is used, and 6 mg of hexyl butyrate is loaded in the capillary, and then both ends of the capillary are sealed to form a slow-release device containing anti-pheromone.

[0011] The slow-release device is directly wound or fixed on the crop branch with a thin thread, and 500 release devices are arranged in each hectare field, and are collected after 100-150 days.

Embodiment 2

[0013] A conventional PVC capillary tube is used, and 8 mg of hexyl butyrate is loaded in the capillary tube, and then both ends of the capillary tube are sealed to make a slow-release device containing anti-pheromone.

[0014] The slow-release device is directly wound or fixed on the crop branch with a thin thread, and 500 release devices are arranged in each hectare field, and are collected after 100-150 days.

Embodiment 3

[0016] A conventional PVC capillary is used, and 10 mg of hexyl butyrate is loaded in the capillary, and then both ends of the capillary are sealed to make a slow-release device containing anti-pheromone.

[0017] The slow-release device is directly wound or fixed on the crop branch with a thin thread, and 500 release devices are arranged in each hectare field, and are collected after 100-150 days.

Abstract

The invention discloses a method for preventing and treating lygus lucorum by using adverse sex pheromone to interfere mating, belonging to the field of the bionic prevention and treatment technology. The method disclosed by the invention is suitable for integrated control of lygus lucorum; the pheromone interferes and stops the mating of lygus lucorum after being released by a pheromone slowly releasing device so as to reduce the mating rate by more than 60%, thus realizing the effect of reducing descendants of lygus lucorum. The method disclosed by the invention has high specifity, causes no influence to natural enemies, is nontoxic, free of residue and environment-friendly, causes no resistance to drugs, is easy to get raw materials of the releasing device, simple and operable, hardly influenced by natural conditions, and has high mating interference capability and long effectiveness duration time.

Description

technical field [0001] The invention belongs to the technical field of bionic prevention and control, and in particular relates to a method for preventing and curing Lygus japonica by using anti-sex pheromone to interfere with mating. Background technique [0002] Lygocoris lucorum belongs to Hemiptera, Lygocoris family. Also known as mosaic insects, small bedbugs, etc., they are distributed in various cotton regions in my country. They are the dominant species of various stinkbugs that harm cotton in the Yellow River Basin and Yangtze River Basin of my country. The green Lygus gnats and nymphs suck the sap from the terminal buds, young leaves, flower buds and young bolls of plants, and the damaged leaves form "broken leaf madness" with a large number of holes and shrinkage; the damaged axillary buds and growth points cause clusters of axillary buds, forming Broom seedlings; damage to flower buds will cause flower drop; damage to fruit to form deformed fruit and rough fruit...
