Problems solved by technology

[0003] There have been reports in China that armyworms can be used to breed Japanese chasing flies, but due to the limitation of the host, it has not solved the bottlenecks of annual parasitism and release at any time.
[0004] Through document retrieval, do not see the public report identical with the present invention

Embodiment 1

[0018] Utilization of silver print of the present invention is the concrete steps of the method for the intermediate host breeding Japanese chasing fly:

[0019] (1) Feeding the intermediate host silver leaf moth

[0020] Collect the healthy larvae of silver print moth from the wild, under the condition of room temperature 25 ℃, relative humidity 75%-90%, light condition L:D=16:8, raise with the artificial feed that the market buys, larva lasts 10 -15 days, 6-9 days in the pupal stage, 11-15 days in the adult stage;

[0021] (2) Breeding of fly source

[0022] Collect the silver leafworm larvae that have been parasitized by the japonica parasite from the wild, and also raise them to pupation according to the conditions of the above-mentioned (1) step, collect the pupa of the japanese chasing fly near its pupa, collect the fly pupae and put them away Put into the insect cage, after the adult emerges, put into the cage the honey water of 0.5% by volume and the milk powder solu...

Abstract

The invention relates to a method for breeding exorista japonica townsend by using argyrogramma agnate as an intermediate host, belonging to the field of biological prevention and control technology. The method for breeding exorista japonica townsend by using argyrogramma agnate as the intermediate host comprises the following steps: feeding the argyrogramma agnate with artificial feed indoors; breeding the exorista japonica townsend by using the argyrogramma agnate as the intermediate host; and storing and releasing the pupas of the exorista japonica townsend. The method provided by the invention has the advantages that: the exorista japonica townsend can be uninterruptedly bred in a large scale and used for preventing and controlling lepidoptera pests in fields; and the application of biological prevention and control on various kinds of crops is promoted, thus the use of chemical pesticide is greatly reduced, the pesticide residue is reduced, and the manpower and material resourcesare saved.

Description

Technical areas: [0001] The present invention relates to the technical field of biological control, specifically a method for breeding Japanese chase flies using Spodoptera exigua as an intermediate host. Background technique: [0002] The artificial breeding and release of natural enemy insects is an important technical measure for biological pest control, among which the artificial breeding and utilization of parasitic natural enemies plays a very important role. my country has numerous available natural enemy insect resources. Due to the lack of suitable alternative hosts and corresponding scientific breeding approaches and methods, only some natural enemy insects can be artificially bred and utilized. The Japanese chase fly has a wide distribution in my country, has no diapause in its life history, and has a very wide host spectrum. For example, it can parasitize American white moth, armyworm, masson pine caterpillar, cotton bollworm, rice bract, corn borer, Lepidopteran...
