Problems solved by technology

[0004] In the existing indoor artificial breeding methods of seven-spot ladybugs, there is no mature system method that can enable the seven-spot ladybug to reproduce stably and keep good characters. In the current method, there are always seven-spot ladybugs that can complete life history, but the fecundity is not strong, the lack of research on egg production methods, and the problem that a large number of subcultures cannot be realized
The test insects of the seven-spot ladybug rely on field collection, and there is no stable insect source for continuous multi-generation breeding, which limits its research work and also limits its release and application in the field as a natural enemy insect

Abstract

The invention belongs to the technical field of insect breeding and particularly relates to a substrate for trapping coccinella septempunctata for oviposition. The substrate for trapping the coccinella septempunctata for oviposition takes selected tea powder and cereal starch as raw materials, water and agar are added, a liquid substrate or a solid substrate is selectively prepared, the smell effect of adult coccinella septempunctata can be effectively utilized, and the trapping effect on the coccinella septempunctata is improved.

Description

technical field [0001] The invention belongs to the technical field of insect cultivation, and in particular relates to a substrate for trapping ladybugs to lay eggs. Background technique [0002] Aphids are extremely harmful pests in agriculture, causing irreversible damage to plants and the environment, and have caused considerable disasters in both greenhouses and fields. At present, the control of aphids is mainly based on pesticide control. Although the effect is remarkable, it inevitably causes great chemical pollution due to excessive use of chemical pesticides, causing secondary damage. [0003] Coccinella septempunctata L. is one of the dominant natural enemies of aphids. Coccinella septempunctata L. belongs to the order Coleoptera and the family Coccinellidae. It is an important predatory natural enemy of aphids on major crops such as wheat, cotton, oilseeds and vegetables. Research at home and abroad has proved that the use of seven-star ladybug to control aphids...
