A method of obtaining black soldier fly egg masses in winter

Abstract

The invention relates to a method for obtaining hermetia illucens spawns in winter. The method comprises the steps that hermetia illucens larvae is cultured to pupae with fresh chicken manure and thenplaced into a glass culture dish so as to be cultured to imagoes; in a room of 4-8 m<2>, 200-500 hermetia illucens imagoes are placed into a gauze cage, lighting is continuously conducted for 3-6 hours with a 1000-watt iodine-tungsten lamp under the condition that an air conditioner is switched off, after lighting is finished, the air conditioner is switched on, the temperature is set to be 25-25DG C, and the relative humidity is made to reach 50-70% by using a humidifier; after lighting is conducted for 3-5 days and then finished, and in the next continuous 3-6 days, apple cores are used asspawning lures every day so as to trap the hermetia illucens spawns. The method has the advantages that few raw materials are used, the sources of raw materials are easy to obtain, and the cost is low; the raising process is simple, and the operation is easy; the spawning amount per unit is high, and livestock manure is easily treated with hermetia illucens; the requirements for collecting the hermetia illucens spawns in winter are met.

Description

technical field [0001] The invention relates to a method for obtaining resource insect egg masses, in particular to a method for obtaining black soldier fly egg masses in winter. Background technique [0002] In recent years, my country's rapidly developing livestock breeding industry has produced a large amount of livestock and poultry manure, which will cause nitrogen and phosphorus pollution to the environment. The manure also contains a large number of harmful microorganisms, pathogenic bacteria and parasite eggs. Formation of pathogenic bacteria contamination. The resource utilization of livestock and poultry manure has been paid attention by the state and departments at all levels. The most effective way to treat livestock and poultry manure is to convert livestock and poultry manure into odorless and harmless organic fertilizer for crops. [0003] The black soldier fly Hermetia illucens, also known as the bright-spotted flat-horned soldier fly, belongs to the Diptera...

Problems solved by technology

[0004] The suitable temperature for the growth of black soldier flies is about 27°C. Adults need strong light for mating and laying eggs. However, in the middle and lower reaches of the Yangtze River Basin such as Hubei Province, the average monthly temperature in winter is 2-12°C, with more precipitation and insufficient light. This limits the development of the black soldier fly population and has become a key issue restricting the industrialization of black soldier flies. Therefore, it is necessary to explore the method of raising black soldier flies in winter to meet the needs of the industrialization of black soldier flies.
