Abstract

The invention discloses an attractant for Anagrus nilaparvatae (natural enemies of rice planthoppers), which comprises components including gaultherolin, cis-3-hexenal, liquid paraffin, 2, 6-di-tert-butyl-p-cresol and 2-hydroxy-4-methoxybenzophenone in a weight ratio of (0.01-0.10): (0.01-0.10):(0.2-2):(0.01-0.1):(0.01-0.1). In the invention, the attractant is made by artificially synthetic pest attracting volatile matters and can attract female adults of Anagrus nilaparvatae which are important natural enemies of rice planthoppers in ovigerm stage to reduce the quantity of rice planthopper colonies and reduce the damage of the rice planthoppers. The attractant has the characteristics of low cost, high efficiency, environmental friendliness, safety for human beings and livestock and the like.

Description

technical field [0001] The invention relates to a natural enemy attractant capable of effectively controlling the adult population of rice planthopper, in particular to a natural enemy attractant for controlling the population number of rice planthopper by using insect pest-induced host plant volatiles and a preparation method thereof. Background technique [0002] Rice planthopper is one of the most important pests on rice, the main food crop in my country, among which the white-backed planthopper Sogatella furcifera and brown planthopper Nilaparvata lugens (St?l) is the most harmful. If it is not prevented and controlled in time, it will cause extremely serious losses to rice production in my country when the outbreak is severe. In 2005, a large outbreak of rice planthoppers occurred in most of the rice producing areas south of the Yangtze River in my country, which brought huge losses to the national rice production. The lesson is very profound. At present, the contr...
