Hylobitelus xiaoi Zhang adult attractant and trapping utilization method of Hylobitelus xiaoi Zhang adult attractant for disinsection in forest

Abstract

The invention discloses a hylobitelus xiaoi Zhang adult attractant and a trapping utilization method of the hylobitelus xiaoi Zhang adult attractant for disinsection in forest. The hylobitelus xiaoi Zhang adult attractant comprises the following components by weight percentage: 30-70% of alpha-pinene, 5-20% of beta-pinene, 0-20% of acetaldehyde, and 10-30% of ethanol. The invention also discloses a utilization method of the above attractant, which comprises trapping core production by using the attractant, trap making and field trapping. The prepared attractant can effectively attract the hylobitelus xiaoi Zhang adult to move, the hylobitelus xiaoi Zhang adult climes into the trap, and cannot escape from the trap due to design of a tunnel-type bottleneck, so that trapping can be completed, the making of the trap and the utilization operation of the trap in forest are easy, insect-catching effect is obvious, and the hylobitelus xiaoi Zhang adult attractant can realize ecological and rational control for hylobitelus xiaoi Zhang adult population.

Description

technical field [0001] The invention relates to the technical field of deworming in forest trees, in particular to an attractant for Pine weevil xiaoshii adults and its trapping and application method for deworming in forests. Background technique [0002] At present, the pine rhizome of Shaw ( Hylobitelus xiaoi Zhang) is a major forestry pest that has recently broken out in southern my country. Pinus xiaoshii is a highly concealed pest, and its eggs, larvae and pupae all live in the bark. The larvae invade the base of the trunk or the root neck to damage the phloem tissue. In severe cases, the transportation of organic nutrients is cut off, resulting in the death of the tree, and even causing a large amount of slash pine to shed resin, thereby reducing the production of turpentine. Since the pest was first discovered in Jiangxi Province in 1988, it has successively occurred in Hunan, Hubei, Guangdong, Guangxi, Guizhou and Fujian provinces, and the damage area has reached...

AI Technical Summary

Problems solved by technology

At present, artificial capture or chemical control methods are mainly used to reduce the density of insect population in the forest, or forest management measures are used to reduce the source of insects and inhibit the reproduction of pests. These methods are not only inefficient, but also have high labor costs or afforestation costs, which pollute the environment.
