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 propagating wild silkworm black egg wasps by using eggs produced by masson pine caterpillars. The method is to use the host-recognized kairoxin of the wild silkworm wasp isolated from the sex accessory glands of the female moth of the silkworm or the wild silkworm to apply it to the masson pine caterpillar to produce eggs, so that the wild silkworm can parasitize in nature and cannot parasitize The masson pine caterpillar produces eggs, and can complete the whole development process in the masson pine caterpillar, until the wild silkworm black egg wasp emerges from the masson pine caterpillar. From the ovum produced by the masson pine caterpillar, the wild silkworm black egg wasp can still reproduce from generation to generation. The method of the present invention is expected to excavate the parasitic potential of the wild silkworm black egg wasp, develop into another natural enemy of the masson pine caterpillar, contribute to the long-term protection of the masson pine forest and achieve sustainable development, and create a new method for further successfully controlling the damage of the masson pine caterpillar to the masson pine a new way.

Description

technical field [0001] The invention relates to a method for propagating the wild silkworm black egg wasp by using the eggs produced by the masson pine caterpillar. 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 behav...
