Chemical inducing agent used for attracting dispersion type pinewood Nematoda

Abstract

A chemical attractant for the diffusion type pine nematode is composed of component A (alpha-pinene), component B (beta-pinene) and optional component C (longifdene) in weight ratio of (27-90): (9-73): (1-5).

Description

technical field [0001] The invention relates to a chemical attractant, in particular to a chemical attractant for trapping diffuse pine xylophilus Background technique [0002] Pine wood nematode is the number one disease of pine trees caused by invasive alien organisms in my country. It is commonly known as the "cancer" of pine trees. Once a pine tree is infected with this disease, it will die completely within half a year or as short as two months. Since it was first discovered near Sun Yat-sen's Mausoleum in Nanjing in my country in 1982, the disease has spread to more than 10 provinces and cities including Jiangsu, Anhui, Guangdong, Guangxi, Zhejiang, Fujian, Shanghai, Chongqing, Hubei, Shandong, and 86 counties. , The affected area reached 1.26 million mu, posing a serious threat to the 500 million mu of pine forests in the south. And the scope is still expanding year by year. More than 6 million pine trees are killed every year, causing direct economic losses of 2.5 b...
