Embodiment Construction
[0015] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with specific examples.
[0016] In recent years, with the strengthening of people's awareness of environmental protection and the requirements of agricultural sustainable development, the research on the control technology of Lygus three-spotted bug has entered a new period. The use of sex pheromones to trap and control male Lygus three-spotted bugs can directly reduce the damage of adults to crops, and on the other hand, greatly reduce their mating rate and the population of offspring, so as to achieve the goal of effectively controlling Lygus three-spotted bugs.
[0017] Through experiments, we found that the crude extract extracted from the sex glands of the female Lygus three-spotted bug has the same strong ability to attract males as live females. We carried out chemical analysis and instrum...

Abstract
The invention discloses a sex attractant for adelphocoris fasciaticollis reuters and application of the sex attractant. The sex attractant for the adelphocoris fasciaticollis reuters is composed of 4-carbonyl-trans-2-hexenal, hexyl butyrate and butyric acid-trans-2-hexene ester, and the mass ratio of the 4-carbonyl-trans-2-hexenal to the hexyl butyrate to the butyric acid-trans-2-hexene ester is 1:11:(0.005-0.03). The sex attractant for the adelphocoris fasciaticollis reuters is uniformly mixed with an organic solvent difficult to volatilize; then the mixed solution is put into a sealed plastic bottle; the plastic bottle is fixed on a sticky coloured card trap for trapping male adelphocoris fasciaticollis reuter adults. The sex attractant for the adelphocoris fasciaticollis reuters can be accurately used for observing and predicting insect pest situations of the adelphocoris fasciaticollis reuters, trapping a large number of the adelphocoris fasciaticollis reuters, and disturbing the mating of the adelphocoris fasciaticollis reuters and has significance in comprehensive treatment of the adelphocoris fasciaticollis reuters.
Description
technical field [0001] The invention relates to the technical field of insect sex pheromone preparation, in particular to a sex attractant for Lygus trispotae and its application. Background technique [0002] Miridae three-spotted bugs belong to the order Hemiptera and belong to the family Miridae. Distributed from Heilongjiang, Inner Mongolia, and Xinjiang in the north, slightly across the Yangtze River in the south, it also occurs in Jiangsu, Anhui, Jiangxi, Hubei, and Sichuan. Main harmful crops: cotton, sesame, soybean, corn, sorghum, wheat, tomato, alfalfa, potato, etc. [0003] For a long time, chemical control has been an important means to control Lygus three-spotted bug. The main pesticides are insecticides with strong contact, systemic and fumigating properties, such as carbamate pesticides such as cypermethrin and kung futhrin, organophosphorus pesticides such as phoxim, malathion and chlorpyrifos, imidacloprid, pyridine, etc. Neonicotinoid pesticides such as ...
