A kind of artificial feed for ladybug larvae and its preparation method and application

Abstract

The invention discloses an artificial feed for ladybug larvae, a preparation method and application thereof. Its steps are as follows: (1) Put the apple snail egg mass in a homogenizer, add an appropriate amount of sterilized water to homogenate, filter to remove the egg shell, and use it as component A. (2) Grinding complex vitamin B and vitamin C, filtering to remove large particles; (3) putting glucose, sucrose, complex vitamin B and vitamin C into a beaker, adding distilled water to dissolve, as B component; (4) soybean powder , Chilo suppressalis pupae powder and yeast powder are mixed evenly as component C; (5) heat and melt the agar with water, then add sorbic acid, honey, boil, cool, add cholesterol, and use it as component D for subsequent use; (6) mix Add component A, component B and component C together, stir evenly, then add component D, continue to stir well. The invention has the characteristics of low price, economical and practical, easy preparation and the like, and is suitable for large-scale, long-term and subculture breeding of standard test insects.

Description

technical field [0001] The invention relates to an insect artificial feed and a large-scale feeding method, in particular to a heterochromia artificial feed and its preparation method and application. Background technique [0002] Harmonia axyridis is a common predatory natural enemy. Harmonia axyridis belongs to Coleoptera (Coleoptera), Coccinellidae (Coccinellidae), and is widely distributed in various regions of China except Hong Kong (Liu Zhen et al., 2009), has the characteristics of strong adaptability, wide feeding habits, large food intake, strong fecundity, etc., and has a strong control effect on the eggs of aphids, whiteflies, scale insects, mites and Lepidoptera pests. Dominant natural enemies have received extensive attention in world biocontrol research and applications (Koch, 2003). At present, the application of Heterochromia in biocontrol is mainly limited by large-scale artificial breeding and factory production, which are manifested in the lack of artific...

AI Technical Summary

Problems solved by technology

Existing artificial feed for ladybug heterochromia, some are pasty feed, some are powdery feed, all are inconvenient to take food

In the process of raising Heterochromia indoors, due to the shortage of aphid sources and the limitation of seasons, the artificial mass breeding of Heterochromia was affected, resulting in the failure of the normal biological control work in the next year.
