Embodiment 1

[0020] The headspace extraction method was used to extract the release of the female Lygus meridian, and it was found that the crude extract had an attractive effect on the adult male Lygus meridianus. We analyzed the crude extract by GC-MS and GC-EAD, and found that the female Lygus meridian There are three main components of the mirid bug release: hexyl butyrate, 4-carbonyl-trans-2-hexenal, and phyllyl hexanoate. See the results in figure 1 .

[0021] Using various ratios, through repeated field trapping experiments, the specific components of the sex lure of Lygus chinensis were finally determined as follows:

[0022] Hexyl Butyrate 80-90%

[0023] 4-Carbonyl-trans-2-hexenal 9-19%

[0024] Folate caproate 0.1-1%.

[0025] Provide 4 specific formulas in table 1:

Abstract

The invention discloses an adelphocoris suturalis sex attractant which comprises the following ingredients in weight percentage: 80-90% of hexyl butyrate, 9-19% of 4-carbonyl-trans-2-hexenal and 0.1-1% of cis-3-Hexenyl caproate. The invention also discloses an application of the adelphocoris suturalis sex attractant in trapping adelphocoris suturalis. The adelphocoris suturalis sex attractant and the application thereof have a good attractive effect on the adelphocoris suturalis, particularly the male adults, has strong selectivity so as not to cause damage to beneficial insects and natural enemies of the adelphocoris suturalis, can not produce resistance, can be used for killing the male adults of the adelphocoris suturalis by attraction and disturbing mating, and has great significance in comprehensive treatment of the adelphocoris suturalis and cotton planting.

Description

technical field [0001] The invention relates to a sex attractant of Lygus melanogaster and its application. Background technique [0002] Lygus chinensis is a major pest on cotton in the Yangtze River Basin. It has a wide range of hosts, strong damage to transplants, and rapid population growth. Chemical control can achieve the effect of killing insects and reducing the density of pests in the short term, but if it is used for a long time, it will induce the resistance of Lygus chinensis, pollute the environment, kill natural enemies, and cause great harm to humans and animals. The sex attractant has strong selectivity, will not cause harm to beneficial insects and natural enemies, and will not produce resistance, and can accurately lure and eliminate pests, which is of great significance to integrated pest management. Contents of the invention [0003] The purpose of the present invention is to provide a sex attractant for Lygus melanogaster with good attracting effect. ...
