Attractant for batocera horsfieldi and application of attractant

Abstract

The invention belongs to the fields of forestry insect prevention and control, and particularly relates to an attractant for batocera horsfieldi and an application of the attractant. The attractant provided by the invention comprises 1,3-dihydroxyhexanediol, 3-hydroxyhexyl acetate, 1-hydroxyl-3-hexyl acetate and 1,3-dihexyl acetate. The attractant disclosed by the invention is utilized to attractand kill the batocera horsfieldi, female adult batocera horsfieldi can be efficiently and specially attracted, so that the purposes of concentrated attracting and killing can be achieved, an egg yieldof the batocera horsfieldi can be significantly reduced, a pest population density in a coming year can be reduced, and the purposes of prevention and control are achieved; experiments confirm that 99% or more of attracted and killed insect species are target insect species, a ratio of other insect species is very small, and most of attracted and killed insects are pests, such as scarabs; and theattractant has no attracting effect on beneficial insects and is suitable for large-scale promotion.

Description

technical field [0001] The invention belongs to the field of forestry insect control, and in particular relates to an attractant for longhorn beetle and its application. Background technique [0002] Beetle beetle is an important tree borer pest, which can harm nearly 100 kinds of broad-leaved trees such as poplar, walnut, chestnut, pear, white wax, etc. At present, beetle beetle is widely distributed in large areas of my country, especially for Central China, East China. The fast-growing and high-yielding poplar forests in Southwest China and other places are severely endangered. The poplar trees are damaged by the beetle, and the tree vigor is weakened, and the whole plant is dead. At the same time, the damage also caused damage to the material of the poplar, reducing the material grade. Make economic and ecological benefits suffer huge losses. [0003] Beetle is a holometabolous insect, and its larvae are mainly damaged by borers. The larval period reaches 12-14 months. ...

AI Technical Summary

Problems solved by technology

The adults eat the cortex of the twigs of pear trees, pomelo trees and other nutritional hosts during the period of supplementing nutrients, making the fruit trees unable to bear fruit, etc.

[0004] The eggs, larvae, and pupae of the beetle beetle are hidden in the trunk, and the larvae have complex boreholes, which disperse the damage. It is difficult and time-consuming to control the larval stage; the body wall and elytra of the adult are thick and hard, and the protection mechanism is relatively complete, and The eclosion period is relatively scattered, and general chemical control is also difficult to be effective
