Abstract

The invention discloses an anagrus nilaparvatae attractant. The anagrus nilaparvatae attractant comprises the following components in the weight ratio of gaultherolin to cis-3-hexenoicaldehyde to linalool to cis-3-hexenylacetate to liquid paraffin to 2,6-ditertiary butyl p-cresol to 2-hydroxy-4-methoxy benzophenone of 0.01-0.10:0.01-0.10:0.01-0.10:0.01-0.10:0.2-2:0.01-0.1:0.01-0.1. The anagrus nilaparvatae attractant has induction effect on female adult of the important natural enemy, namely the anagrus nilaparvatae, of rice planthopper at egg stage, so that the number of the anagrus nilaparvatae population is reduced and damage to rice plants is reduced. The anagrus nilaparvatae attractant has the characteristics of low cost, high efficiency, environmental friendliness, safety to people 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 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 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 control of rice pl...
