Abstract

The invention discloses a method for increasing the parasitic rate of glyphodes pyloalis parasitic wasps by using methyl caffeate. The method comprises the following steps: preparing a methyl caffeate solution; providing mulberry leaves containing the methyl caffeate for glyphodes pyloalis larvae to eat; and providing the glyphodes pyloalis larvae which eat the mulberry leaves containing the methyl caffeate for the mixed chamber to parasiticus. When the method is used for breeding the mixed-chamber cotesia, the parasitism efficiency is high, the loss is small, the operation is simple and convenient, the cost is low, the problem that leaf rolling of larvae of the stem borer family is not beneficial to parasitism of the parasitic wasps is solved, large-scale indoor production of mulberry pest mixed-chamber cotesia parasitic wasps is facilitated, and an important foundation is laid for field biological control work of the glyphodes pyloalis.

Description

technical field

[0001] The invention belongs to the technical field of biological control of agricultural pests, and relates to a method for increasing the parasitic rate of parasitic wasps of the major mulberry pest, mulberry borer. Background technique

[0002] The mulberry moth Glyphodes pyloalis belongs to the Lepidoptera of Lepidoptera and Pyralida of the family Pyralidae. It is one of the major pests on mulberry trees in my country and Southeast Asian countries. It can grow rapidly, and the phenomenon of overlapping generations is obvious, causing a large area of ​​mulberry leaves to be eaten and damaged, and in serious cases, causing mulberry leaves to fail. In addition, the feces of mulberry borer larvae can easily pollute mulberry leaves, resulting in a decline in the quality of mulberry leaves. The larvae are also bridge hosts for many pathogenic microorganisms in silkworms. After eating mulberry leaves contaminated by mulberry borers, silkworms are very susceptible...
