Thrips attractant

Abstract

The invention discloses a thrips attractant containing, by weight, 50-70% of a plant extract, 5-10% of nerol, 5-10% of carvacrol and the balanced being ethanol. The plant extract, the nerol, the carvacrol and the ethanol are mixed according to certain ratio, so that the thrips attractant has good attractive effect on the thrips and can significantly improve prevention and treatment effect of agricultural compounds on the thrips. The thrips attractant has huge application potential in prevention and treatment of the thrips for crops.

Description

Technical field [0001] The thrips attractant of the present invention contains plant extracts, nerol, ethanol and carvacrol. The plant extracts are extracted from the mixture of young mango inflorescences, cowpea flowers, and banana inflorescences. The plant extracts and nerol, The mixture of ethanol and carvacrol in a certain proportion has a good attracting effect on thrips, significantly improves the effect of agricultural compounds in preventing and controlling thrips, and has a wide application potential in the prevention and control of thrips in crops. Background technique [0002] Thrips are insects of the Insecta Thysanoptera, which are distributed throughout our country and have been damaged for a long time, and the phenomenon of overlapping generations is prominent. Thrips host a wide range, mainly damage cucurbit crops, leguminous crops, gramineous crops, solanaceous crops, lily crops, bananas, mangoes, etc. Almost all vegetables are harmed by them, and without control...

AI Technical Summary

Problems solved by technology

[0003] Chemical control of thrips in crops usually has a very good effect, but the application of pesticides cannot be completely uniform, and the systemic conductivity of some compounds is not good enough. Uneven application of pesticides and the defects of the compounds themselves often lead to ineffective chemical control of thrips. Ideally, some crops such as leguminous plants are severely damaged by thrips during flowering. Many leguminous crops such as cowpea have the habit of closing flowers. The opening time is mainly concentrated at 7-9 in the morning. It is harmful in flowers, and it is difficult to achieve the ideal control effect with medication during the clestasis period. Tang Deliang et al. published in the "China Plant Protection Guide" No. 3, 2016, the research on the effect of spraying before and after clestasis of cowpea on the control effect of thrips shows that, Control effect of cowpea thrips before cleistoanthesis on cowpea is significantly better than that on cowpea thrips after cleistosome
