Embodiment Construction

[0019] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0020] 1. Using a plant volatiles dynamic headspace collection device to collect volatile substances in kidney beans

[0021] Plant volatiles dynamic headspace collection device such as figure 1 shown. The device consists of an air pump 1, a flow meter 2, an ultrapure water washing cylinder 3, an activated carbon drying tower 4, an adsorption container (glass cylinder) 5, and an adsorption tube 6. The glass cylinder 5 consists of upper and lower parts with an inner diameter of 20cm , high 60cm, connect adsorption pipe 6 at the bottom of the lower half of glass cylinder 5, adsorption pipe 6 puts into internal diameter and is 0.1cm, is divided into air inlet and air outlet.

[0022] Select 5 host plants, kidney beans, and put them in a 2000ml beaker, add ultrapure water until the underground part of the plant is covered, and then put the beaker into a g...

Abstract

The invention discloses an application of a kidney bean volatile matter in expelling an invasive pest Frankliniella occidentalis. The kidney bean volatile matter is 2, 6-di-tert-butyl-p-cresol. The invention discloses application of 2, 6-di-tert-butyl-p-cresol in repelling an invasive pest Frankliniella occidentalis. The invention relates to a repelling agent capable of repelling the invasive pest Frankliniella occidentalis, and the effective component of the repelling agent is 2, 6-di-tert-butyl p-cresol. The substance which can be used as a source of the invasive pest Frankliniella occidentalis repellent can be bought on the market and can be extracted from a volatile matter of a Frankliniella occidentalis host plant kidney beans, and the 2, 6-di-tert-butyl p-cresol can be used for producing the Frankliniella occidentalis repellent, or a certain area of kidney beans are directly planted for repelling the Frankliniella occidentalis; and when the botanical repellent is used for repelling the Frankliniella occidentalis, the botanical repellent has the characteristics of no pollution, high efficiency and stable performance, is suitable for production of current organic vegetables and pollution-free vegetables, and is convenient to transport.

Description

technical field [0001] The invention belongs to the technical field of pest green prevention and control, and specifically relates to the application of existing materials in the aspect of avoiding the invasive pest western flower thrips, so as to develop corresponding preparations for preventing and controlling western flower thrips. Background technique [0002] Western flower thrips Frankliniella occidentalis (Pergande), which belongs to Thysanoptera Thripaceae flower thrips genus, also known as alfalfa thrips, is a worldwide quarantine pest, and it is also the first batch of invasive alien insects under key management in my country. The worm originated in the western part of the United States and Canada, and has now spread to countries and regions in Europe, Asia, Africa, Oceania, Central and South America. The range of host plants of Western flower thrips is very wide, as many as 66 families and more than 500 species, including a variety of important economic crops, veg...
