Problems solved by technology

Although chemical pesticides have obvious effects and quick results, the long-term and large-scale use of pesticides will inevitably lead to the resistance of Lygus bugs, forcing farmers to continuously increase the amount of pesticides used to control pests, resulting in a vicious cycle of drug resistance and increased dosage, with very serious consequences.

Abstract

The invention discloses lygus pratensis linnaeus attractant and applications thereof. The lygus pratensis linnaeus attractant comprises components in parts by weight as follows: 45-79 parts of hexyl butyrate, 10-20 parts of 4-carbonyl-trans-2-hexenal, 10-20 parts of trans-2-hexenyl butyrate, 1-5 parts of trans-2-hexenyl acetate, 0.8-4 parts of methyl myristate, 0.2-2 parts of 4-methyl pentyl butanoic acid and 0.2-2 parts of (Z)-3-hexenol butanoic acid. The lygus pratensis linnaeus attractant can be accurately applied to insect situation prediction, mass entrapment and mating disruption of lygus pratensis linnaeus and has significance on comprehensive treatment of lygus pratensis linnaeus.

Description

technical field [0001] The invention relates to the technical field of preparation of insect sex pheromones, in particular to an attractant of Lygus bug and its application. Background technique [0002] Lygus pratensis Linnaeus belongs to Hemiptera, Lygus pratensis family. It mainly occurs in Xinjiang in my country. The main harmful crops are cotton, alfalfa, potato, fragrant pear, jujube, etc., which bring huge economic losses to agricultural production. For a long time, forage ligud bugs have mainly been controlled by chemical means, such as pyrethroids, carbamates, organophosphorus, and neonicotinoids. Although chemical pesticides have obvious effects and quick results, the long-term and large-scale use of pesticides will inevitably lead to the resistance of Lygus bugs, forcing farmers to continuously increase the amount of pesticides used to control pests, resulting in a vicious cycle of drug resistance and increased dosage, with very serious consequences. .
