Artificially synthesized phyllocnistis citrella stainton gyplure

Abstract

The invention discloses an artificially synthesized phyllocnistis citrella stainton gyplure. The gyplure is prepared by the following steps: mixing cis7 cis11-hexadecadienal, cis7 cis11 trans13- hexadecatrienal, cis7-hexedecanal and ethyl acetate in proportion by weight parts of 30:(1-30):(0.1-20):(0.1-20); adding 0.1 to 1 weight percent of vitamin E, TBHQ (tert-butyl hydroquinone), BHT (butylated hydroxytoluene) or BHA (butylated hydroxyanisole) as an antioxidant; and adding 0.1 to 1 weight percent of benzophenone, benzotriazole or hindered amine and mixture as an optical stabilizer. The artificially synthesized phyllocnistis citrella stainton gyplure has the following advantages: phyllocnistis citrella stainton diseases can be prevented and monitored, the trapping effect can be intensified and cost can be reduced, industrial efficiency improvement and orchard worker income increase can be facilitated, orange pesticide residue does not exist, the environment is not polluted, ecological balance is not destroyed, and sustainable development of orange industry is facilitated.

Description

technical field [0001] The invention discloses an insect sex attractant, in particular to an artificially synthesized citrus leafminer sex attractant. Background technique [0002] Citrus leafminer (Phyllocnistis citrella stainton) belongs to Lepidoptera and Lepidopteridae. After feeding, the insect will form irregular hollow tunnels on the surface of young leaves and shoots, so it is also known as drawing insect, ghost painting symbol, doodle The eggs of this insect are only laid on the young shoots and leaves of citrus, and the leaves will be rolled up and surrounded by the body to pupate near the leaf edge, and the larvae and pupae will be laid on the late autumn shoots, winter shoots or autumn shoots of citrus. Over the winter, the kill rate of autumn shoots is 100%. At the same time, a large number of wounds are caused by the young leaves and shoots of citrus being mothed, which often induces the occurrence of citrus canker. In addition, the citrus leafminer reproduce...

AI Technical Summary

Problems solved by technology

However, due to differences in populations of citrus leaf miners in different countries and regions, cis 7 cis 11 trans 13-hexadecatrienal, cis 7 cis 11-hexadecadienal, cis 7-hexadecadienal Whether the mixture of carbenals has attractant activity to citrus leaf miner populations in different geographic regions needs further study

Fujian is one of the main production areas of citrus, and the damage of citrus leaf miner is serious. In recent years, sex attractants have been widely used to control citrus leaf miner. 13-hexadecatrienal, cis-7-cis-11-hexadecadienal, and cis-7-hexadecenal are mixed as sex attractants.
