Large-scale production method of tamarixia radiate

Abstract

The invention discloses a large-scale production method of tamarixia radiate. The method comprises the steps that s1, carrier plants are managed, tender shoots are cultivated, and the carrier plants are calamondin; s2, diaphorina citri is inoculated to the carrier plants in a diaphorina citri breeding cage, and nymphs are bred; s3, the carrier plants with the 4-5-age diaphorina citri nymphs are moved into a parasitic wasp breeding cage, tamarixia radiate adults are put into the parasitic wasp breeding cage, the inoculation quantity ratio of tamarixia radiate to the diaphorina citri nymphs is 1: 10-20, and the tamarixia radiate adults are bred and collected; and s4, the carrier plants are cleaned and recovered. The carrier plants developed by the method are calamondin, the carrier plants shorten the growth cycle, the breeding capacity of the diaphorina citri and the production capacity of parasitic wasps are greatly improved, and the net yield and the female ratio of the tamarixia radiate are effectively improved according to the inoculation proportion of calamondin+tamarixia radiate to the diaphorina citri nymphs.

Description

Technical field:

[0001] The invention belongs to the technical field of biological control of agricultural pests, and in particular relates to a method for large-scale production of the bright-bellied wasp. Background technique:

[0002] Citrus psyllid (Diaphorinacitri Kuwayama) is the main pest of citrus plants in the young shoot stage. It sucks the plant juice through the piercing-sucking mouthparts, and lays eggs on the new shoots, often causing the new shoots to wither and deform, and excrete White honeydew, which causes sooty rot. What's more serious is that, as the main insect vector for the transmission of Huanglongbing bacteria, it often leads to the outbreak of Huanglongbing disease in orchards. After a few years, the diseased trees infected with Huanglongbing will lose their economic value. The development of the industry, at present, has not yet found an effective method for the treatment of Huanglongbing.
