Problems solved by technology

At present, the breeding method of the flat-bellied wasp in the prior art is mainly to use the host eggs (natural, artificial) to reproduce under the conditions of constant temperature and humidity, and the reproductive efficiency is not very ideal. Experience, bold attempts, creative experimental research, found that the change of specific temperature and humidity can improve the breeding effect of the flat-bellied beetle, after a lot of research, continuous improvement, and then complete the present invention

Embodiment 1

[0018] 1. Test method: (test repeated three times)

[0019] (1) Spread the tussah ovum into a petri dish, and then insert the healthy and mated A. orientalis female, the ratio of the number of the orienta orientalis female to the tussah ovum is 1:10, and at the same time feeding honey water;

[0020] (2) The petri dish is placed on 20 ℃, in the artificial climate box of 55% relative humidity, cultivates 2 days; Then the temperature in the artificial climate box is adjusted to 24 ℃, relative humidity 60%, cultivates 2 days; The temperature in the climate box is adjusted to 27°C, the relative humidity is 65%, and it is cultivated for 3 days. After the flat-bellied orientalis lays eggs, the parasitized tussah eggs are taken out from the artificial climate box, and then selected and set aside;

[0021] (3) select 15 white plastic boxes of 30cm * 30cm * 20cm, all put into 5 sections of Ailanthus ailanthus tree segments that have the ovum piece of spotted coat wax cicada in every b...

Abstract

The invention discloses an artificial breeding method of Anastatus orientalis and an application in forest pest control. Ova of Antheraea pernyi are selected as alternative hosts for Anastatus orientalis, and suitable breeding conditions are screened, so that the parasitic capability of Anastatus orientalis is significantly improved. Lycorma delicatula is controlled by means of Anastatus orientalis, and the parasitic effect of Anastatus orientalis on Lycorma delicatula ova is good.

Description

technical field [0001] The invention relates to the technical field of pest biological control, in particular to an artificial breeding method for artificially breeding Anastatus orientalis and the application of Anastatus orientalis in preventing and controlling forest pests. Background technique [0002] Lycorma delicatula belongs to the Homoptera family Fulgoridae of the order Homoptera. It mainly harms Ailanthus altissima, Toona sinensis, Melia azedarach, Robinia pseudoacacia, Populus sp., Salix sp., Vitis vinifera and Malus sp. and many other trees and fruit trees. Widely distributed in my country, it is a native pest in our country. Due to the influence of natural enemies and other factors, it only occurs sporadically in some areas of our country. In recent years, the damage of the spotted-coated cicada in the grape plantations of our country has shown an aggravating trend. The spotted-coated wax cicada was introduced into South Korea in the 1930s, but it did not caus...
