Living body cold storage method of serangium japonicum

Abstract

The invention provides a living body cold storage method of serangium japonicum. The method includes steps of diapause induction, cold coma storage, diapause termination and the like. The method specifically includes that the serangium japonicum is put in an environment with alternate illumination and darkness for 240 hours so that the serangium japonicum enters diapause; the serangium japonicum that enters diapause is stored at low temperature in a dark place; the serangium japonicum that is stored at low temperature in the dark place is taken out and put at the room temperature under lighting conditions for 20 minutes, and the serangium japonicum starts to move and restores to eat; after 8 days in the environment of 22-28 DEG C and photoperiod (L: D= 13h: 11h), egg production capacity of female adults of the serangium japonicum is recovered. By means of the living body cold storage method of the serangium japonicum, diapause adjustment and control of the serangium japonicum can be achieved through adjustment of temperature and photoperiod, the serangium japonicum can be stored in a common refrigerator for a long time without supplement of preys, the problem of failure of storage of live serangium japonicum can be solved, and propagation expanding of the serangium japonicum can be facilitated whenever possible.

Description

technical field [0001] The invention relates to the field of biological technology, in particular to a method for refrigerating living bodies of the Japanese ladybug. Background technique [0002] The crop yield loss caused by agricultural diseases and insect pests accounts for 10-15% of the total loss every year in my country. The scientific management of agricultural diseases and insect pests has important economic and social benefits for the implementation of the national food security strategy and the promotion of high agricultural yields. Whitefly pests seriously harm various crops, including mulberry trees, tea trees, citrus, flowers, cotton, vegetables, etc. Among them, Bemisia tabaci, which harms vegetables, has no specific drugs to control it due to its strong drug resistance. Greenhouses often seriously damage vegetables for a long time, and are called "super pests". [0003] The use of natural enemy insects to control whiteflies can continuously control the damag...

Problems solved by technology

[0008] The technical problem to be solved in the present invention is to overcome the deficiencies in the prior art, and to provide a method for refrigerating the living body of the Japanese ladybug, which realizes the diapause control of the Japanese ladybug by adjusting temperature and photoperiod, so that the Japanese ladybug Insects can be stored in ordinary refrigerators for a long time without supplementing prey, which solves the problem that live Japanese ladybugs cannot be stored
