Abstract

The invention provides a method for culturing predatory ladybirds. The method comprises the following steps: (1) breeding aphids by using seedlings of a host plant, and cutting plant seedlings with the aphids into small sections when the number of the aphids of each seedling is increased to 600-1300; (2) putting ladybird egg masses into breeding boxes, and feeding hatched ladybird larvae with theaphids obtained in the step (1); and (3) before the ladybirds pupate, putting folded paper pieces into the breeding boxes, and collecting pupae of the ladybirds. By adopting the method, the ladybirdsin the breeding boxes are fed with the small sections of the plant seedlings with the aphids, so that spatial separation of aphid breeding and ladybird breeding is achieved, the aphids can be added and changed conveniently, the ladybirds are not damaged, and the propagation efficiency of the ladybirds can be improved. The method provided by the invention is simple, efficient, low in cost and applicable to on-scale production of ladybirds.

Description

technical field [0001] The invention relates to a method for cultivating predatory ladybugs, and belongs to the technical field of feeding predatory ladybugs. Background technique [0002] Bean aphids belong to the family Aphididae of the order Homoptera, and mainly feed on leguminous crops such as beans, peas, and broad beans. Bean aphids have strong fecundity, and one generation can be completed in 4 to 6 days. Each wingless viviparous female can produce more than 100 nymphs, so it is very easy to cause serious damage. [0003] Predatory ladybugs, including seven-spotted ladybugs and heterocolored ladybugs, belong to the Coleoptera order Coleoptera and the ladybug family Coccinellidae. They have the characteristics of large food intake, many eggs, and many annual generations. They are important predatory natural enemies in agricultural production. Insects; can prey on a variety of aphids, whiteflies, leafhoppers, thrips and the eggs and larvae (nymphs) of ladybugs of the ...
