Abstract

The invention discloses an attractant for Anagrus nilaparvatae which are natural enemies of rice planthoppers, which comprises components including linalool, liquid paraffin, 2, 6-di-tert-butyl-p-cresol and 2-hydroxy-4-methoxybenzophenone in a weight ratio of (0.01-0.10):(0.2-2):(0.01-0.1):(0.01-0.1). The attractant can attract female adults of Anagrus nilaparvatae which are important natural enemies of rice planthoppers in ovigerm stage, so as to reduce the quantity of rice planthopper colonies and reduce the damage of the rice planthoppers to rice plants. The attractant has the characteristics of low cost, high efficiency, environmental friendliness, safety for human beings and livestock, and the like. The attractant for Anagrus nilaparvatae which are the natural enemies of the rice planthoppers have a bright industrialization prospect; and as the preparation method is simple, the attractant is particularly suitable to be used in pollution-free production of rice and can create great economic, social and ecological benefit.

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 quantity of rice planthopper by utilizing volatile matter of host plants induced by insect pests. 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 major outbreak of brown planthoppers occurred in most of the rice-producing areas south of the Yangtze River in my country, which brought huge losses to the country's rice production. The lesson is very profound. At present, the control of rice ...
