Scale breeding method for encarsia formosa

Abstract

The invention discloses a scale breeding method for encarsia formosa. The scale breeding method is finished in four greenhouses, namely a host plant cultivating room, a worm species room, an encarsia formosa species room and a breeding room, by steps. The scale breeding method comprises a host plant cultivating and managing step, a whitefly species managing step, a whitefly inoculating step, a whitefly nymph breeding step, an encarsia formosa species managing step, an encarsia formosa inoculating step, an encarsia formosa pupa breeding step, a pupa collecting step, a worm card or encarsia formosa box manufacturing and storing step and a whitefly controlling step. The scale breeding method has the advantages that process steps are continuously circulated and the encarsia formosa can be annually produced and bred. The scale breeding method is suitable for industrial scale production and reproduction of the encarsia formosa and is short in reproduction period, high in efficiency, low in energy consumption and low in cost. The obtained adult encarsia formosa, encarsia formosa pupa card or encarsia formosa box products are good in quality. The problem of insufficient supply for control over bemisia tabaci and trialeurodes vaporariorum in agriculture and forestry is solved.

Description

technical field [0001] The invention belongs to the technical field of biological control of agricultural and forestry pests, and in particular relates to a method for large-scale propagation of Lithias wasps used in the process of biological control of agricultural and forestry pests. Background technique [0002] Whitefly is an important pest of agricultural and forestry crops. There are whiteflies all over the world that endanger the production and development of agricultural and forestry crops to varying degrees. Whitefly has file-sucking mouthparts. Adults and nymphs suck plant juice and secrete A large amount of honey liquid induces and spreads a variety of mycotic diseases. It has a wide range of hosts and harms more than 600 kinds of plants in more than 100 families such as flowers, fruit trees, medicinal materials, and tobacco. The population of whiteflies is huge, with strong reproductive ability and fast reproduction speed. Cluster damage, the leaves of the damage...

Problems solved by technology

[0005] The present invention aims at the problems in the prior art that the survival rate of the limpet wasp is low under the condition of artificial propagation, the breeding cycle is long, the annual supply of large quantities cannot be realized, and the needs of green production of modern agriculture and forestry cannot be met, and a kind of limpet is provided. The large-scale breeding method of small bees, the method is completed step by step in the four greenhouses of the host plant cultivation room, the insect species room, the bee species room and the breeding room, and the specific steps are as follows:
