A kind of attractant for adult beetle beetle

Abstract

The invention discloses an attractant for adult beetle beetle. The attractant comprises (E)-β-Farnesene or contains six isomers (E)-β-Farnesene, (Z)-β-farnesene, (E,E )-α-Farnesene, (Z,Z)-α-Farnesene, (E,Z)-α-Farnesene and (Z,E)-α-Farnesene of Farnesene. The attractant can attract both female and male adult beetles. The attractant can be used to lure female and male adults in the wild, providing practical pollution-free monitoring and control technical means for monitoring the occurrence period and amount of adults in the forest or large-scale trapping and killing.

Description

technical field [0001] The invention relates to the field of forest pest control, in particular to an attractant for adult beetles. Background technique [0002] Anopolophora glabripennis (Motsch.) belongs to the order Coleoptera, the family Cerambycidae, the subfamily Lamiinae, and the genus Anoplophora[1]. The insect is an important borer pest of broad-leaved tree species such as poplar, willow, elm, and maple [2]. Beetle glabrata is widely distributed in my country, and it is rampant in some parts of northern my country. It has caused serious damage to the "Three North" shelterbelts in my country. Only 40% of the poplar forests in the first phase of the project have been destroyed by beetle glabrata. In recent years, the insect has been rampant in Hebei, Henan, Shandong, Anhui, Shaanxi, Gansu, Xinjiang, Inner Mongolia, Heilongjiang and other provinces. At the end of the last century, the bare-shouldered star beetle had spread to North America, which caused the panic of ...

Problems solved by technology

[0004] It is difficult to prevent and control long beetle beetle. Due to its long life history, its eggs, larvae and pupae all live in the trunk, and the individuals are scattered and live alone. It is rarely affected by external bad weather and natural enemies, so the natural control effect is relatively weak.

Because it is difficult to kill longhorn beetle larvae inside the tree with chemical or biological insecticides, and it is difficult to use chemical pesticides intensively for control because the adult eclosion period is irregular and takes a long time, so how to control its damage is always a big problem
