Attractant for attracting ips typographus together

Abstract

An attractant for attracting ips typographus together belongs to the technical field of forest pest control. The attractant is made from the following raw materials with the following weight proportions: 0.6-4.5 parts of trans-2-hexenyl-1-ol, 0.6-4.5 parts of cis-verbenol and 0.6-4.5 parts of 2-methyl-3-butylene-2-ol. The attractant contains a non-host volatile composition replacing expensive ipsattribute pheromone (I) Ipsdienol in a foreign formula, which greatly lowers production cost, and used raw materials are free of pollution and environment friendly. After use of the attractant, attraction effect of the attractant is improved by more than 94% compared with that of the attractant with the best effect reported abroad and improved by more than 38% compared with that of the attractantdisclosed in a patent with an application No. 200810051469.2. Therefore, the ips typographus attractant has wide application prospect, is especially suitable for popularization and application for peasants, achieves targets of population monitoring and control, minimizes loss caused by damages of ips typographus of China, and has obvious economic, social and ecological benefits.

Description

technical field [0001] The invention relates to the technical field of forest pest control, in particular to an attractant for trapping the spruce bark beetle. Background technique [0002] The spruce bark beetle is one of the most harmful bark beetles in Europe. It is a secondary pest that harms natural spruce forests (generally mature and over-mature forests). It can directly harm Healthy standing trees, and together with other bark beetles, cause large areas of forest trees to die, causing huge losses to forestry production and ecological environment construction. In June 2003, EPPO announced that the spruce beetle is widely distributed in 52 countries and regions all over the world, and is extremely harmful in 12 low-latitude countries and regions. Historically, large-scale outbreaks of the spruce beetle have caused huge economic losses to Picea abies (L.) Karst. in the Norwegian spruce forest, and spread rapidly and widely through various channels. In China, the spruc...

Problems solved by technology

A large number of studies have shown that cV and MB are the basic components of the pheromone of the spruce beetle, and (-)-Ipsdienol can have a positive synergistic effect when mixed with the above two components at low concentrations, but (-97 %) - Ipsdienol is very expensive

[0004] The application document of application number 200810051469.2 discloses a spruce octopus beetle composed of cis-3-hexenyl-1-ol, cis-verbenaenol and 2-methyl-3-buten-2-ol Although its effect exceeds that of foreign attractants, the price is relatively high
