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) All are plant-derived substances: the main components are all derived from plants; 2) The attractant effect is not ideal
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.
The patent application number is 201010577064.X, an attractant for Monochamus alternatus adults, which is composed of 95% α-pinene and 40% acetaldehyde. The attractant has the following disadvantages: 1) All are plant-derived substances: the main ingredients are all derived from 2) The lure effect is not ideal

Abstract

The invention discloses an Monochamus alternatus adult attractant based on insect patient-oriented pheromone and applications thereof, belonging to the technical field of pest control. The Monochamus laternatus adult attractant based on insect patient-oriented pheromone is characterized in that a key component is 2-undecyloxy-1-ethanol; auxiliary components consist of alpha-pinene of purity 95% and acetaldehyde of purity 40%; and the volume ratio of the alpha-pinene of purity 95% to the acetaldehyde of purity 40% is 2-4:1. According to the monochamus alternatus adult attractant based on insect patient-oriented pheromone and the applications, the insect patient-oriented pheromone, namely 2-undecyloxy-1-ethanol, is screened successfully, the attractant is used together with a traditional botanical attractant, the inducing effect is improved by more than 5 times, especially in the later period (spawning period) of an adult, the trapping effect of the attractant is dozens of times of that of the botanical attractant. The attractant of the invention has the advantages of low cost, long effective duration, good safety, environmental friendliness and the like, can control the harm of Monochamus alternatus, has important significance on restraining the propagation and spreading of pine wood nematode disease, and fills the blank of home and abroad technology.

Description

technical field [0001] The invention belongs to the technical field of pest control, and specifically relates to an insect-derived pheromone-based attractant for monochamus alternatus adults, a preparation method and application. Background technique [0002] Pine xylophilus disease is called "cancer" of pine trees. Its pathogen, Pine xylophilus, is the largest foreign invasive species in forestry in my country, and Monochamus alternata is its main vector in China. At present, trapping and killing adults of Monochamus alternatus with plant-derived attractants is one of the most commonly used control methods, but the trapping and killing effect of plant-derived attractants is not very satisfactory, which has also become the main factor that limits the wider application of Monochamus alternatus attractants. reason. In agriculture, the development and application of moth sex pheromones have been very extensive, such as cotton bollworm and American white moth. However, the dev...
