Attractant synergist at early stage of egg laying of monochamus alternatus hope and preparation method thereof

Abstract

The invention discloses an attractant synergist at the early stage of egg laying of monochamus alternatus hope and a preparation method thereof. The attractant synergist includes a pheromone mixture which has high-efficiency attraction activity for the monochamus alternatus hope and a synergist, wherein the pheromone mixture includes tepenes (C5H8)n, ethanol C2H6O, isopropyl alcohol, acetaldehyde C2H4O, acetone C3H4O3, benzoic acid C6H5COOH, eugenol C10H12O2, turpentine and turpentine oil and synergist S-ipsdienol, wherein n is equal to 2; and the substances are mixed in the ratio of 0.5:5:3:2:1:1:1:2:1:0.5. The attractant synergist has the advantages of high efficiency, safety, environmental friendliness, safety for human beings and animals, no drug resistance of pests and the like; and most importantly, average fecundity of adults trapped by the attractant is higher; and the attractant synergist has higher attraction activity for the monochamus alternatus hope at the early stage of egg laying and higher application value.

Description

technical field [0001] The invention relates to an attractant synergist for monochamus longicorn monochamus in the early oviposition period and a manufacturing method thereof, and belongs to the technical field of disease and insect pest control. Background technique [0002] Monochamus alternatus, also known as Monchamus alternatus Hope, is the main transmission medium of pine xylophilus. Its pesticides and its natural enemies are difficult to contact the insect body, and it has the characteristics of heavy harm, strong concealment, and difficult control. It is widely distributed in China, North Korea, Laos, Vietnam, Japan and other countries. In my country, it is mainly distributed in most areas south of the Yellow River Basin. The host range of the monochamus is quite wide, including pine, larch, cedar, fir and spruce, etc. Among them, it is most fond of masson pine, black pine and red pine, and its larvae harm the weaker pine trees, destroying Cutting off its dredging t...

AI Technical Summary

Problems solved by technology

[0007] 1. Due to the extensive production of the lure core, its volatilization rate has not been effectively controlled, the lure cycle is short, and the existing efficiency is low. The lure core needs to be replaced after 10-15 days to enhance the lure effect

Therefore, this attractant makes the cost increase and increases the difficulty to the actual operation in the forest

[0008] 2. The product has a good attracting effect on Monochamus alternatus during the spawning period, but has a low attracting activity on Monochamus alternatus in the early spawning period

The average fecundity of adults trapped by the attractant is low, which shows that this kind of attractant is beneficial to reduce the population of Monochamus alternatus, or as a method of forest population monitoring, but it cannot cut off the transmission route of B. xylophilus
