Feeding rice moth larvae with plastic foam as host breeding method

Abstract

The invention discloses a method for breeding corcyra cephalonica larvae with plastic foam as hosts to breed bracon adoxophyesi mimankawa. The corcyra cephalonica larvae can be fed on the plastic foamto complete growth and development, the foam texture is light, the corcyra cephalonica larvae are easy to be separated from the foam, the foam can be better supplied to allow the bracon adoxophyesi mimankawa to search for parasitism, the parasitic effect is very good, and the reproduction efficiency is high. The plastic foam further has anti-mites and bacteriostatic effect, maintains the stability of the growth and development environment of the bracon adoxophyesi mimankawa, and further has a very good effect. In addition, a large number of plastic foam is used for replacing grain feed as a feed source and a feeding medium for the corcyra cephalonica larvae, the environmental pollutants are reduced, meanwhile, the plastic foam of environmental waste is turned into treasure, and a way to degrade the pollution of the plastic foam in the future is provided. A large number of parasitic bee sources are provided for the control of palm plant pests coconut woven moths and tirathaba rufivenawalker and the other prevention and control technology application by making further use of corcyra cephalonica larvae to breed the bracon adoxophyesi mimankawa.

Description

technical field [0001] The invention belongs to the fields of energy saving and environmental protection, new generation biotechnology of agriculture and forestry, and relates to a method for raising natural enemy parasitic wasps, and in particular to a method for breeding the wasp moth by using rice moth larva fed by plastic foam as a host. Background technique [0002] Palm plants are landscaping trees in tropical areas and southern coastal areas of my country, and are also important economic plants. Coconut and betel nut, which are important representatives of palm plants, have a planting area of ​​more than 3 million mu in Hainan. They are an important pillar industry of tropical crops and an important means for 500,000 coconut farmers in Hainan Province to get rich. However, with modern trade exchanges, intensified human activities, and crop structure adjustments, changes in palm species composition, biological populations, and community structures have resulted in the ...

AI Technical Summary

Problems solved by technology

At present, corn flour, wheat bran, soybean powder and white sugar are mainly used as feed for rice moth larvae. Because rice rice moth has low digestibility of grain feed, and the feces discharged are mixed with food and feed, it is easy to cause uneaten feed to be lost. Contaminated, causing a lot of feed waste

On the other hand, the larvae of the rice moth raised indoors are latent in the feed, covered by powdered grain feed, and mixed with the silk and feces of the rice moth. Therefore, it is difficult for the larvae of the rice moth to directly contact the larvae of the rice moth. For parasitism, it is necessary to manually strip the rice moth larvae from the grain feed and provide them for the parasitism of the brown banded moth wasps, which increases the cost of artificial labor
