Embodiment 1

[0025] This embodiment provides a method for improving the utilization rate of tussah silkworm eggs by Trichogramma borer.

[0026] The method for improving the utilization rate of tussah silkworm eggs by Trichogramma borer may include the following steps:

[0027] (1) the abdomen of the tussah moth is separated from the cephalothorax, the abdomen of the moth is minced, cleaned with pure water for 3 times, and then the impurities are removed to obtain the tussah silkworm eggs;

[0028] (2) Use 0.1% bromogeramine to soak the tussah eggs for 3 minutes for disinfection, then place them in a sterile, ventilated environment and dry them at room temperature to obtain the sterilized tussah eggs;

[0029] (3) Use 0.1% bromogeramine to soak the seed bees of Trichogramma japonica and Trichogramma pine caterpillar respectively for 3 minutes to disinfect the egg surface, and then place them in a sterile and ventilated environment to dry at room temperature to obtain sterilized Trichogramm...

Embodiment 2

[0033] This embodiment provides a method for improving the utilization rate of tussah silkworm eggs by Trichogramma borer.

[0034] The method for improving the utilization rate of tussah silkworm eggs by Trichogramma borer may include the following steps:

[0035] (1) Separate the abdomen of the tussah moth from the cephalothorax, mince the abdomen of the moth, wash it with purified water for 5 times, and remove impurities to obtain tussah eggs;

[0036] (2) Use 0.1% bromogeramine to soak the tussah eggs for 8 minutes for disinfection, then place them in a sterile, ventilated environment and dry them at room temperature to obtain the sterilized tussah eggs;

[0037] (3) Use 0.1% bromogeramine to soak the seed bees of Trichogramma japonica and Trichogramma pine caterpillar respectively for 6 minutes to disinfect the egg surface, and then place them in a sterile and ventilated environment to dry at room temperature to obtain sterilized Trichogramma japonica Bee breeding and di...

Embodiment 3

[0041] This embodiment provides a method for improving the utilization rate of tussah silkworm eggs by Trichogramma borer.

[0042] The method for improving the utilization rate of tussah silkworm eggs by Trichogramma borer may include the following steps:

[0043] (1) the abdomen of the tussah moth is separated from the cephalothorax, the abdomen of the moth is minced, cleaned with pure water for 4 times, and then impurities are removed to obtain tussah silkworm eggs;

[0044] (2) Use 0.1% bromogeramine to soak the tussah eggs for 5 minutes for disinfection, then place them in a sterile, ventilated environment and dry them at room temperature to obtain the sterilized tussah eggs;

[0045] (3) Use 0.1% bromogeramine to soak the seed bees of Trichogramma japonica and Trichogramma pine caterpillar respectively for 5 minutes to disinfect the egg surface, and then place them in a sterile and ventilated environment to dry at room temperature to obtain sterilized Trichogramma japoni...

Abstract

The invention relates to a method for increasing the utilization rate of antheraea pernyi eggs by trichogramma chilonis. The method specifically comprises the steps that firstly, antheraea pernyi moths are treated to obtain the antheraea pernyi eggs; secondly, parasitic breeding wasps are disinfected and sterilized; when the eclosion rate of the breeding wasps reaches 20-30%, the breeding wasps begin to be inoculated onto the antheraea pernyi eggs, the trichogramma chilonis is inoculated according to the wasp-egg ratio of (7-9):5 at first, and 6-10 h later, trichogramma dendrolimi is inoculated onto the host eggs according to the wasp-egg ratio of (1-3):5; 38-42 h later, adult wasps are removed, the remaining wasps are put into a full dark condition with the temperature of 25+ / -1 DEG C andthe humidity of 80-85% for culture; finally, the eggs are dissected to examine the development states of the wasp bodies, so that storage or putting into use is timely carried out. By means of the method, the utilization rate of the antheraea pernyi eggs in the factory production process of the trichogramma chilonis is effectively increased, the production process of mixed wasps is simplified, the production cost is reduced, and a technical guarantee is provided for the large-scale production and large-area field application of the wasps.

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 improving the utilization rate of tussah silkworm eggs by Trichogramma borer. Background technique [0002] Trichogramma is an oviparasitic wasp used to control agricultural and forestry pests. It is widely used and has achieved good economic, ecological and social benefits. Trichogramma borer has a high application prospect because of its many control objects and wide application range. It has a good control effect on various agricultural and forestry pests, and can reproduce on tussah eggs, so it has great application potential. But production finds Trichogramma borer parasitic effect on tussah eggs is low, general parasitic rate can only reach 50-70%, tussah eggs have a loss rate of 30%-50%, waste of resources, increased production costs. [0003] Trichogramma pine caterpillar is the largest type of Trichogramma pine ...
