A method for rearing lady beetles using a mixed diet of Mediterranean mealworm eggs and rape pollen

Abstract

The invention discloses a method for raising red ladybugs using mixed food of mealworm eggs and rape pollen, and relates to the field of insect feeding, specifically comprising the following steps: S1, raising eggs of mealworms; S2, using mealworm eggs Eggs and rape pollen are mixed to feed the larvae of the red ladybug, waiting for pupation and eclosion; S3, identifying the sexes of the newly emerged adult beetles, and then pairing the sexes and laying eggs; S4, collecting the egg masses of the red ladybug , can multiply after incubation. This application adopts the mixed breeding of Mediterranean mealworm eggs and rape pollen. The cost of feeding raw materials is low, and artificial breeding is simple. It can ensure the adequacy of food and reduce the breeding cost. The individual ladybugs are healthy, the survival rate is improved, and continuous multi-generation stable breeding is realized.

Description

technical field [0001] The present invention relates to the field of insect breeding, in particular to a method for rearing lady beetles using the mixed food of Mediterranean mealworm eggs and rape pollen. Background technique [0002] Micraspis discolor (Fabricius) is one of the dominant species of predatory natural enemies of rice field pests. It preys on a variety of rice pests including thrips, rice aphids, leafhoppers, planthoppers, lepidopteran larvae and eggs, and has control over the brown planthopper. It is distributed in Zhejiang, Jiangxi, Hubei, Hunan, Sichuan, Fujian, Guangdong, Guangxi, Yunnan, etc. After entering the 90-year belt, its population density plummeted in Jiangxi. The large-scale breeding of the red ladybug can be used for field control, reducing the use and harm of chemical pesticides, protecting the environment and maintaining public health. Most of the existing methods for breeding the red lady beetle are artificial breeding using the natural pre...

Problems solved by technology

[0003] Using natural prey-aphids as food can certainly breed better-quality red ladybugs, but this method requires artificial planting of host plants for aphids to reproduce, and the population of aphids has a natural law of ebb and flow. The adequacy of food cannot be guaranteed during the worming process

Secondly, using the feeding method of host plants-aphids-ladybugs, in addition to the need to invest a lot of material and space costs, is also extremely dependent on artificial

The use of fruit flies as live feed to feed rice red ladybugs has the following disadvantages: larval survival rate is low, development time is prolonged, final adult emergence is less and less active, mating behavior is less, and it cannot reproduce to the next generation; this technology has not been systematically developed The process of feeding ladybugs cannot be well guided by the systematic multiplication of red ladybugs; Drosophila is a very convenient food source, but natural food always encounters the problem that its number will increase and decrease with time in the process of feeding ladybugs, and it is difficult to Ensure food adequacy over time
