Adult monochamus alternatus hope attractant

Abstract

The invention discloses an adult monochamus alternatus hope attractant, which belongs to the technical field of prevention and control of pests. The attractant is characterized by comprising 95 percent alpha-pinene and 40 percent aldehyde in the volume ratio of (1-5):1. In the adult monochamus alternatus hope attractant, the 95 percent alpha-pinene serving as an active ingredient and the 40 percent aldehyde serving as a synergistic substance are compounded, so that the attracting effect of the attractant is enhanced greatly and the trapping quantity of adult monochamus alternatus hopes in a feeding period accounts for 70 percent of the total trapping quantity; moreover, the attractant has the advantages of simple production process, low cost, environmental friendliness and the like, is safe, can effectively control the woodland population density of monochamus alternatus hopes and prevents the spreading and the transmission of pine wilt disease.

Description

technical field [0001] The invention belongs to the technical field of pest control, in particular to an attractant for Monochamus alternatus adults. Background technique [0002] Pine wood nematode is the largest foreign invasive species in my country's forestry industry. Monochamus alternatus is its main transmission medium in China. After pine trees are infected with pine wood nematode disease, it leads to the destruction and death of resin duct parenchyma cells and epithelial cells, causing plant damage. Loss of water, reduced transpiration, sharp reduction and cessation of resin secretion, which will cause huge economic losses to forestry resources. Therefore, to control the spread of pine wood nematode, the key is to control the population of Monochamus alternatus in the forest. The use of botanical attractants to trap and kill adults of Monochamus alternata is one of the most commonly used and most effective control methods, and it is of great significance for control...

AI Technical Summary

Problems solved by technology

The attractant has the following disadvantages: 1) The specific active ingredients are not clear, and the attractant ingredients are the crude extracts of the host plant, and no specific compound components have been studied; 2) The processing and production process is complicated, and the needles of the host plant or Bark extraction, felling and depletion of large pine trees

The attractant has the following disadvantages: 1) The composition is complex and the production cost is high, and the specific active ingredients of the attractant are very complicated, with as many as 7 kinds, resulting in high production cost; 2) The attracting effect is not ideal; The effect of attracting adults is poor. After many years of comparative experiments, the inventors have shown that the feeding stage adults attracted by this attractant account for about 50% of the total amount of adults trapped.
