Method for inducing wing shortening of Sogatella furcifera

Abstract

The invention relates to a method for inducing the wing shortening of Sogatella furcifera by utilizing an exogenous hormone, namely ZR-515 solution. The adopted technical scheme comprises the following steps of: freezing nymphs of the Sogatella furcifera at 3 to 4 ages, then dripping a small amount of juvenile hormone analogue, namely the ZR-515 solution on the backs of the nymphs, and raising the treated nymphs in a raising container for 2 to 8 days. The invention aims to design a novel, simple and convenient scheme for inducing the wing shortening of the Sogatella furcifera to improve the acquisition of short-winged individuals in the process of raising for experimental research materials, or provide a possible way for applying the method to fields and controlling the migration and dispersion hazard of the Sogatella furcifera in the future.

Description

technical field

[0001] The invention relates to a method for using exogenous hormone ZR-515 solution to induce short wings of white-backed planthopper. Background technique

[0002] White-backed planthopper ( Sogatella furcifera (Horvath)) belongs to the family Delphacidae of the order Homoptera, and is currently a serious pest to rice in my country and many Asian countries. The nymphs of white-backed planthopper are divided into five instars. The adult stage has two types: long-winged and short-winged. It belongs to the sedentary type, with fast development speed and relatively strong reproductive ability. The proportion of long-winged and short-winged types in the population can change with changes in environmental conditions or different feeding conditions.

[0003] A large number of studies have shown that raising the feeding temperature can reduce the formation of short-winged adults of planthoppers, and the use of short light can promote the formation of short-winged...
