A kind of sex attractant of silk borer

Abstract

The invention relates to a diaphania angustalis sex attractant which is characterized by comprising the following active ingredients: trans,trans-10,12-hexadecenal (E10E12-16:Ald) and trans,trans-10,12-hexadecenol (E10E12-16:OH). The diaphania angustalis sex attractant can be prepared into a lure, and a single lure contains an active ingredient of 50-1500 microg. The lure is put into an armyworm trap, can be used for monitoring the field occurrence dynamics of diaphania angustalis, predicting the harm extent, guiding other control measures to be timely taken, and simultaneously trapping and killing male diaphania angustalis, and has significant ecological, economical and social benefits.

Description

technical field [0001] The invention relates to a sexual attractant for the green-winged silk borer. Background technique [0002] Alstonia scholaris, also known as lampstand tree and sugar gum tree, is not only a medicinal plant with high economic value, but also has a majestic tree shape, rapid growth, and strong resistance to air pollution. It is also an excellent garden and greening tree species, but the The tree is vulnerable to pests such as the green-winged silk borer Diaphania angustalis (Snellen), and it is often seen in southern China that the leaves of the pots on the roadside or in the park are completely eaten by it. [0003] The green-winged silk borer belongs to Lepidoptera and Boreridae. It is mainly distributed in Guangdong, Guangxi, Sichuan, Yunnan, Fujian and other places. When the larvae are in danger, the larvae spin the silk and roll the leaves of the pot frame vertically, and feed on the mesophyll, leaving the veins And the lower epidermis, the leaves...

AI Technical Summary

Problems solved by technology

[0003] The green-winged silk borer belongs to Lepidoptera and Boreridae. It is mainly distributed in Guangdong, Guangxi, Sichuan, Yunnan, Fujian and other places. When the larvae are harmed, the larvae will spin the silk and roll the leaves of the pot frame vertically, and eat the mesophyll, leaving the veins And the lower epidermis, the leaves gradually dry up and become grayish white or withered yellow and then fall leaves, resulting in bare branches and light poles. In severe cases, the damage rate of plants reaches 90%, and the damage rate of leaves reaches 100%, which affects the photosynthesis of leaves, resulting in abnormal growth of plants and loss of landscape. Affect the ornamental value and growth of trees, and even cause death if the control is not timely

[0004] Insect sex pheromones have great application potential in pest monitoring and control, and more and more people pay more and more attention to them. At present, the research on the green leaf silkworm mainly involves biological characteristics and damage rules, and there is no information about its sex. prime research report
