Artificial massive rapid propagation technical method for brownbanded encarsia formosa

Abstract

The invention discloses an artificial massive rapid propagation technical method for brownbanded encarsia formosa which sequentially comprises the steps of nursery stock purchasing, culture solution preparation, leaf cuttage and water culture, aphid inoculation, aphid culture, bee breeding in a bee breeding room, chalcidoid propagation, stiff aphid collection and adult bee collection, wherein parasitic wasp is encarsia formosa. According to the invention, about 20 days are needed from nursery stock purchasing to harvesting of adult chalcidoid, 200-220 thousand chalcidoids can be bred, and thechalcidoid can also be bred in batches according to a plan. According to the breeding method disclosed by the invention, a massive insect source can be provided for provinces or cities with severe aphid damage, so as to relieve the harm of aphid to crops and lower economic loss. The invention not only provides a rapid propagation method of brownbanded encarsia formosa, but also provides a collecting method of brownbanded encarsia formosa stiff aphid and adult bees, and provides a complete production process for commercialized production of parasitic wasp brownbanded encarsia formosa for the first time, and thus providing a massive natural enemy resource for biological control of aphid.

Description

technical field [0001] The invention belongs to the technical field of biological control of agricultural pests, and in particular relates to an artificial large-scale and rapid breeding method of aphid aphid wasps. Background technique [0002] Food is food to safety first. In the era of advocating environmental protection, health and green food, people hope to ensure the safety, high yield and high quality of crops by using the natural control effect of natural enemies of pests. Therefore, the development of pest biological control has become an inevitable trend. Aphids are one of the important pests in modern agricultural production. They harm a variety of crops, vegetables, fruit trees, and trees. The extensive use of chemical pesticides has led to many problems such as pesticide residues, pest resistance, and environmental pollution, which have greatly affected human health. The biological control measures of aphids are also more urgent, and the wasp is an important n...

Problems solved by technology

[0005] Some scientific research institutions in the domestic existing technology may be able to realize the breeding of Aphis spp. brown bees, but they are all carried out in the laboratory and are in the stage of small-scale breeding. The monthly bee production of small-scale breeding can only meet the bees used in the experiment. No large-scale breeding method has been developed, so that the wasp can not be used for the control of field aphids in the field, so the production process of artificial mass breeding of the wasp still needs to be further improved
