Monochamus alternatus imago attractant

Abstract

The invention relates to a monochamus alternatus imago attractant which belongs to the technical field of pest control. The monochamus alternatus imago attractant contains the following components according to volume percent: 60-80 percent of turpentine oil, 16-24 percent of ethanol, 2-10 percent of phenethyl alcohol and 2-6 percent of terpilenol. The monochamus alternatus imago attractant contains the following ingredients according to volume percent: 24.64-32.86 percent of Alpha-pinene, 22.91-30.55 percent of Beta-pinene, 6.51-8.68 percent of 3-carene, 2.97-3.96 percent of Beta-phellandrene, 0.74-0.99 percent of terpinolene, 0.62-0.83 percent of laurene, 1.60-2.13 percent of others, 16-24 percent of ethanol, 2-10 percent of phenethyl alcohol and 2-6 percent of terpilenol. The monochamus alternatus imago attractant has remarkable attracting effect to both monochamus alternatus female worms and male worms, and stronger attracting effect to the male worms; and also has certain attracting effect to other coleopteran forestry pests. The invention has the advantages of high efficiency, environmental protection, simple and convenient preparation, low cost and good durability, can be used for prediction and control in monochamus alternatus forest with the control effect up to 53.59-67.30 percent and can effectively control the population density in the monochamus alternatus forest and restrains the spread and the extension of pine wood nematode disease.

Description

Technical field: [0001] The invention relates to an adult attractant for Monochamus alternatus Hope, which belongs to the technical field of pest control. Background technique: [0002] Monochamus alternatus, also known as monochamus alternatus, is an important borer pest on pine trees. The direct damage caused to pine trees by the pine monochamus is that its larvae harm the phloem and xylem of weak pine trees and pine trees that are on the verge of weakening, destroy and cut off the transporting tissue, affect the transportation of water and nutrients, and affect the growth of pine trees, resulting in pine tree flakes. and die; adults form wounds on young shoots of healthy pine trees during the nutritional supplementation period, causing them to die. The indirect harm is the spread of pine wood nematode. Pine wood nematode (Bursaphe lenchus xylophilus) is a global invasive alien organism, and is currently an internationally recognized quarantine object. It is one of the m...

Problems solved by technology

Due to the interference of natural diseased trees, especially in the moderately and severely damaged forests, the control effect is relatively poor, so it can only be used as a forecast of insects.

In addition, there are large differences in the attractant effects of these attractants on Monochamus alternatus on different geographical populations and different host tree species.
