Embodiment

[0023] 1) Preparation of silkworm eggs

[0024] Mate the female and male adult moths 3-5 hours after the silkworm chrysalis emerged, and separate them for about 2-5 hours. Put them on a rough surface of kraft paper and cover them with a newspaper to avoid light. When the eggs are basically full , replace the brown paper, and let the moths continue to lay eggs. At the same time, the produced egg cards were cut and separated, and immediately put into a -20°C refrigerator for storage as host eggs for the reproduction of wild silkworm black egg wasps.

[0025] 2) Collection of wild silkworm black egg bee

[0026] In winter, wild silkworm eggs are collected on mulberry branches in mulberry gardens where wild silkworms occur. The collected wild silkworm eggs were packed in parasitoid collection bottles. One end (large mouth end) is sealed with 3 layers of gauze, and the other end (small mouth end) is connected to a clean glass test tube facing the sun and placed at room temperatu...

Abstract

The invention discloses a method for producing ovum anatomy wild silkworm Telenomus sp by utilizing Dendrolimus punctatus Walker, wherein the wild silkworm Telenomus sp host obtained by separation from silkworm or wild silkworm female accessory gland is utilized to identify kairomone into the application of the Dendrolimus punctatus Walkeranatomy ovum, thus enabling the wild silkworm Telenomus sp stray onto the Dendrolimus punctatus Walker anatomy ovum which is not available for parasitism in nature, and the whole growth procedure can be completed in the Dendrolimus punctatus Walker anatomy ovum, until the breeding of the wild silkworm Telenomus from the Dendrolimus punctatus Walker anatomy ovum.

Description

technical field [0001] The invention relates to a method for dissecting eggs from masson pine caterpillars to propagate wild silkworm black egg wasps. Background technique [0002] Hymenoptera insects are playing an irreplaceable role in the biological control of important agricultural and forestry pests. As of 2001, the introduction of natural enemies in the world to successfully control agricultural and forestry pests is as follows: 90 cases of Aphididae, 53 cases of Braconidae, 23 cases of Aphididae, 22 cases of Aphididae, 17 cases of Aphididae, There were 9 cases of Apiidae and 15 cases of other families. All the above successful examples of biological control are based on the fact that these parasitoids parasitize their specific hosts in nature. This is established in the process of biological evolution. [0003] Insect kaimonin refers to a chemical substance secreted by an insect and released outside the body to cause a behavioral response in ...
