Problems solved by technology

[0006] However, the reproduction of aphids is relatively complicated, and the manual operation time is long. It is necessary to rationally allocate the growth and development time of faba bean-aphids-heterochromia, and the cost of raising aphids is relatively high.
These problems have been affecting the artificial reproduction of H. chinensis in large numbers in the factory, and it is likely that the biological control work will not be carried out normally in the following year.

Embodiment Construction

[0027] The principles and features of the present invention are described below, and the examples given are only used to explain the present invention, and are not intended to limit the scope of the present invention.

[0028] 1. Breeding and breeding of Chrysanthemum chinensis

[0029] The newly hatched larvae of Chrysocephala cephalexin were fed with fresh pork tenderloin, and after reaching the 3rd instar, they were fed in a plastic pot mixed with fish meal: wheat bran: water = 1:5:5, the mouth of the pot was covered with gauze, and fed until it pupated. Use a sieve (100 mesh) to separate the pupae from the feed, put the pupae in an insect cage for adults of Chrysocephala macrocephala, and wait for them to emerge. The adults are fed sugar at the early stage, and when they are sexually mature (about 5 days after emergence), they are fed with fresh tenderloin. After copulation, the female lays her eggs on the meat. Take the egg-laying meat out of the cage and place it in an ...

Abstract

The present invention relates to an application of chrysomyia megacephala larvae in feeding of harmonia axyridis, and also relates to a method for feeding harmonia axyridis with chrysomyia megacephalalarvae. The method includes the following steps: S1: feeding chrysomyia megacephala to obtain the chrysomyia megacephala larvae; and S2: feeding the harmonia axyridis with the chrysomyia megacephalalarvae. The artificial feeding method of the invention has the advantages of simple operation, less investment and low production cost, and is suitable for large-scale feeding of harmonia axyridis. Newly hatched chrysomyia megacephala larvae are adopted to feed the harmonia axyridis, the industrialized propagation of the harmonia axyridis can be satisfied, and meanwhile, the aphid control efficiency of releasing the harmonia axyridis in a field can also be improved. The use amount of aphid-killing pesticides can be minimized, the residue of vegetable pesticides is reduced, and the effective biological control of aphids is achieved on the basis of destroying the ecological environment.

Description

technical field [0001] The present invention relates to the field of agricultural biological control, more particularly, relates to the application of Chrysophora macrocephala larvae in raising Heterochromia, and a method for raising Heterochromia by using Chrysocephala larvae. Background technique [0002] At present, under the general environment that the country tends to reduce the amount of pesticides and ensure food safety, biological control is one of the important ways to control pests in agriculture. At present, about 150 kinds of natural enemies are commercially produced and sold in the world, the main species are Trichogramma, grass ridge, predatory mite, small flower bug and ladybug, etc., and have achieved certain social and economic benefits. [0003] Heterochromia, belonging to Coleoptera, Coccidae, is the main predatory natural enemy of a variety of aphids, whiteflies, mites, Lepidopteran insect eggs, young larvae and scale insects and other pests, and has a l...
