Problems solved by technology

[0004] For a long time, the large-scale and stable indoor reproduction of thrips is still a worldwide problem faced by researchers. Because thrips cannot be reproduced with feed, they can only be reared on fresh plants or leaves, such as beans and petals. Strong seasonality, and the commercially available hosts have serious pesticide residues, it is difficult to raise thrips with them, the population is difficult to continue, the source of insects is unstable, and the orderly development of the experiment cannot be guaranteed

Abstract

The invention provides a compound capable of increasing female thrips luring rate and indoor spawning quantity. The compound is prepared by mixing the solutions of octyl aldehyde, hexyl alcohol, geraniol, benzyl alcohol and cis-3-hexene acetate according to the mass ratio of (1-5):(1-20):(1-20):(5-25):(1-25), wherein the solution concentration of each component is 30microgram / ml. The compound is an active substance screened from various thrips host plant volatile substances and is evident in effect, harmless to thrips and the like. The reproduction behavior of the thrips can be stimulated whenthe compound exists, the thrips spawning quantity can be increased greatly, and female thrips luring rate can be evidently increased by more than 50% as compared with male thrips luring rate. The compound provides an important technical approach for indoor thrips population reproduction and provides a great number of stable insect sources for the researches of thrips invasion biological mechanismand drug resistance.

Description

technical field [0001] The invention relates to the fields of insect biology and ecology, in particular to a compound for improving the lure rate of thrips females and the amount of eggs laid indoors. Background technique [0002] Thrips is a general term for insects of the order Thysanoptera. The insects are tiny and often hide in flowers and young leaves to cause damage, so it is not easy to control. Currently, more than 7,700 species of thistles have been recorded in the world, and China accounts for more than 570 species [Majid et al., 2011; Mound et al., 2014]. So far, there are more than 2,000 species of Thrips family recorded in the world, belonging to about 276 genera in 4 subfamilies, and 315 species in 79 genera in China [Hu Qingling, 2013]. At present, thrips is an important carrier for the transmission of various viruses including spotted dwarf virus, and it is also an important invasive foreign pest that breaks out and is a typical small insect pest.
