Artificial propagation method of diversinervus elegans silvestri

A technology for artificial breeding of small pulsating wasps, applied in animal husbandry and other directions, can solve the problems of inoculation and collection of parasitic wasps are difficult to operate, it is impossible to achieve large-scale production, increase the difficulty and cost of reproduction, and ensure field prevention and control. Effect, solve the effect of low reproductive efficiency and large number of bees per generation

Problems solved by technology

The above breeding methods are limited to laboratory research, and the production efficiency is low, so it is difficult to mass-produce on a large scale. The material is bulky and requires a relatively closed environment to prevent...

Embodiment 1

[0018] ⑴Collection of provenance of parasitoid wasps and intermediate host rubber helmeted scales:

[0019] In rubber nurseries or mature rubber gardens that have been infested by rubber helmeted scales, cut off the branches with scale insects rubber helmeted scales attached (some of which have been parasitized by the elegant scorpion) and bring them back indoors. Leave the unparasitized late female scale insects on the branches as intermediate hosts, and wait for the inoculation on the pumpkin as the propagation material to multiply, and put the other part of the scale insects together with the branches into the cage for collecting parasitoids, and wait for the elegant pulse to beat A bee emerges.

[0020] (2) Reproduction of scale insects: the female scale insects of rubber helmeted scale insects as the intermediate host are lifted from the shell and placed on the surface of the pumpkin. The newly hatched nymphs will be scattered and fixed on the pumpkin, and at least 1 / 3 of...

Embodiment 2

[0024] ⑴Collection of provenance of parasitoid wasps and intermediate host rubber helmeted scales:

[0025] On the hibiscus infested by the rubber helmet scale, cut off the branches attached to the rubber helmet scale insect (some of which have been parasitized by the elegant Qimaitiao wasp), and bring them back indoors. Reserve the unparasitized late female scale insects on the branches as intermediate hosts, wait for inoculation on the propagation material for propagation, and put the other part of the scale insects together with the branches into the cage for collecting parasitoids, and wait for the elegant Qi pulse to jump. Bee emergence.

[0026] ⑵Reproduction of scale insects: Remove the scale insects as the intermediate host and place them on the surface of the pumpkin. The newly hatched nymphs will disperse and fix on the pumpkin. At least 1 / 3 of the eggs under the scale insects have hatched into 1st instar nymphs. Put about 30 effective insects to complete the inocul...

Abstract

The invention discloses an artificial propagation method of diversinervus elegans silvestri. In the method, a pumpkin is used as propagation material, parasaissetia nigra nietner is propagated to be used as an intermediate host, the parasaissetia nigra nietner is used for producing the diversinervus elegans silvestri, the parasaissetia nigra nietner used as the intermediate host is inoculated on the pumpkin and cultured for 35-50 days under indoor natural conditions to inoculate a parasitic wasp; the proportion of the male diversinervus to the female diversinervus is controlled to be 2-4 : 1, the diversinervus are fed with 10% honey water, the proportion of the male encyrtid to the parasaissetia nigra nietner is controlled to be 1 : 5, and after 1-3 days, the pumpkin used as the propagation material is taken out; another pumpkin with the intermediate host is used as the propagation material for propagation of the diversinervus elegans silvestri, the parasaissetia nigra nietner is inoculated on the pumpkin for 1-3 days, and then, the provenances of the diversinervus are discarded after inoculating 1-2 pumpkins; the pumpkin being taken out is placed in the room for cultivation under natural conditions, the parasitized parasaissetia nigra nietner used as the intermediate host is cut off by a blade so as to collect honeybee pupae, and the grown diversinervus are collected after the eclosion of the pupae. The method can implement volume production of the diversinervus elegans silvestri, and can effectively solve the problems of low progenitive rate and delayed supply and demand of biological control.

Description

technical field [0001] The invention belongs to the field of biological control of agricultural and forestry pests, and in particular relates to an artificial propagation method of the natural enemy insect of the wax scale. Background technique [0002] Coccidae belongs to the class Insecta, Homoptera, Coccoidea. Among the 20 families of Coccidae, Coccidae is the third largest family, second only to Diaspididae and Pseudococcidae. The amount of wax secreted by scale insects is relatively the largest. According to Ben-Dov (1993 ), about 1088 species have been recorded in the undergraduate course, divided into 144 genera. There are 83 species of 39 genera and 83 species known in my country (Tang Fangde, 1991), among which nearly 30 species are common pests of agriculture, forestry, fruit trees and ornamental plants. The important pests of the wax scale family are: red wax scale, orange green wax scale, Japanese wax scale, brown wax scale, jujube ball wax scale, rubber helmet...
