A kind of method of large-scale reproduction of the brown banded moth Braconis

Abstract

The invention discloses a method for indoor breeding of the brown-banded moth wasps. At 25°C of temperature, light: under the condition of darkness=14h:10h, put into the insect cage with sleeves of 55cm * 55cm * 55cm by the brown scalloped wasp, feed with 15% honey water, every 3 Every day, take out the feed with worms from the breeding tray with 5-6 instar rice moth larvae and spread it on the bottom of the plastic box, so that the height of the feed with worms is about 1.5cm, and put the plastic box without a cover into the parasitic bee insect cage Among them, the parasitic wasps take the rice moth in the feed as their host. After 3 days, the plastic box was taken out, and the lid was covered. After 12 days, the next generation of parasitoids began to emerge, and the emergence time continued for more than 7 days. The invention has the advantages of simple operation and high efficiency, and is easy to realize the large-scale reproduction of the coronis.

Description

technical field [0001] The invention relates to the field of biological control of agricultural and forestry pests, in particular to a method for the large-scale propagation of the brown-banded moth wasps. Background technique [0002] Coconut weaver moth Opisina arenosella Walker is an important pest on palm plants, mainly damaging palm plants such as coconut, palmetto, Middle East date palm, areca nut, and king palm. In August 2013, Wanning City, Hainan Province first discovered the damage caused by the coconut weaver moth, and in December 2013, it was found to be infested by the insect in Guangxi. invade our country. This pest has occurred in India, Thailand, Indonesia and other Southeast Asian countries and regions, and has caused significant economic losses to local palm plants. After it invaded our country, it also attracted the attention of relevant departments. In 2014, it was included in the list of invasive alien pests by the State Forestry Administration. [00...

AI Technical Summary

Problems solved by technology

However, due to the fact that the larvae of its host coconut moth are easily infected with germs and die during the feeding process, and at the same time, the larvae are sneaking under the moth tunnel intertwined with insect feces and silk, the process of raising and changing leaves is heavy, labor-intensive and time-consuming, and it is difficult to achieve large-scale breeding. There are certain difficulties in using it as a host to raise a large number of Braconis mori
