Method for mass reproduction of Bracon adoxophyesi Mimanikawa

Abstract

The invention discloses a method for reproducing Bracon adoxophyesi Mimanikawa indoor. Under the conditions that the temperature is 25 DEG C, and the ratio of light to darkness is 14 h to 10 h, the Bracon adoxophyesi Mimanikawa is placed into an insect rearing cage with a sleeve, wherein the specification is 55 cm*55 cm*55 cm, the Bracon adoxophyesi Mimanikawa is fed by 15% of hydromel, fodder with insects is taken out from a feeding plate with 5-6-instar rice moth larvae every 3 days to be smoothly laid at the bottom of a plastic box to enable the height of the fodder with the insects to be approximately 1.5 cm, the plastic box without a cover is placed in a parasitoid wasp insect rearing cage, and the parasitoid wasp utilizes the rice moth as the host. The plastic box is taken out 3 days later, and the plastic box is covered by the cover, the emergence of the parasitoid wasp of the next generation begins to occur after 12 days, and the emergence time lasts more than 7 days. The method is simple in operation and high in efficiency, and the mass reproduction of the Bracon adoxophyesi Mimanikawa can be achieved easily.

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 weaving 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. [0...

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
