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 attracting diffuse pine wood nematodes Background technique [0002] Pine wood nematode disease is a pine tree disease caused by the number one alien invasive organism in my country. It is commonly known as the "cancer" of pine trees. Once a pine tree is infected with this disease, it will be completely dead for half a year or two months. Since it was first discovered near the Sun Yat-sen Mausoleum in Nanjing 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 and cities. The affected area reached 1.26 million mu, posing a serious threat to 500 million mu of pine forests in the south. And the scope of occurrence is expanding year by year. More than 6 million pine trees are killed every year, causing direct economic losses of 2.5 billi...
