Abstract

The invention relates to an artificial propagation method for parasitic wasps of bactrocera tau larvae. The method comprises the steps of collection of bactrocera tau and adult parasitic wasps of bactrocera tau larvae, feeding and domestication of the parasitic wasps of the bactrocera tau larvae, feeding of the adult bactrocera tau, expanding propagation and spawning domestication of bactrocera tau, egg collection of the bactrocera tau, expanding propagation of the bactrocera tau larvae, parasitism of the parasitic wasps of the bactrocera tau larvae on the bactrocera tau larvae, larva feedingand pupation after parasitism, parasitic pupae collection and parasitic wasp eclosion separation, and rejuvenation of the bactrocera tau and larva parasitic wasps. By adopting the method disclosed bythe invention, the growth and development of the bactrocera tau and the parasitic wasps are not influenced by residual pesticides, and the host searching capability of the parasitic wasps in the fieldis kept stable; after being collected, the bactrocera tau pupae where the parasitic wasps are parasitic do not need freezing treatment, damage to the bactrocera tau pupae where the parasitic wasps are parasitic is little, the separation effect of the bactrocera tau and the parasitic wasps is good, and the method has the advantages of being easy to operate, capable of saving time, little in humaninterference, high in parasitic rate, easy to breed on a large scale and particularly suitable for application and popularization.

Description

technical field

[0001] The invention belongs to the technical field of biological control of agricultural pests, and in particular relates to an artificial propagation method of a parasitoid wasp of the larvae of Bactrocera cerevisiae. Background technique

[0002] Lepidoptera Bactrocera (Zeugodacus) tau Walker is one of the main pests that damage melons, fruits and vegetables, and it is currently causing damage in all provinces and regions in southern my country. Bactrocera melons in natural environments Bactrocera (Zeugodacus) cucurbitae Coquillett competes for the same food resources. Due to its short growth cycle and fast larval development, it has replaced melon fly as the dominant species in this area. At present, in some areas of Guizhou and Yunnan, in the fields of fruits and vegetables caused by Bactrocera larvae, several kinds of parasitoids of Bactrocera larvae have been collected. There is no literature report.
