Problems solved by technology

If the above-mentioned parasitic natural enemies are to be utilized and applied to biological control, the problems of mass reproduction of parasitic natural enemies and how to increase the parasitic rate of parasitic natural enemies must be solved, which is the biggest bottleneck in the application of parasitic natural enemies to biological control

Embodiment

[0024] 1) Preparation of silkworm eggs

[0025] 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.

[0026] 2) Collection of wild silkworm black egg bee

[0027] 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 increasing the parasitism rate of the eggs produced by the wild silkworm black egg wasp parasitizing the masson pine caterpillar. The method is to use the wild silkworm black egg wasp that has not parasitized the host to parasitize the masson pine caterpillar to produce eggs with the wild silkworm black egg host to identify kaixin, so that the wild silkworm black egg wasp has a high parasitism rate to the masson pine caterpillar. Greatly improved, up to 2.5 times the original. While the parasitic rate is increased, the entire development process can still be completed in the eggs produced by the masson pine caterpillar until the wild silkworm black egg wasp emerges from the eggs produced by 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 inventive method is expected to excavate the parasitic potential of the wild silkworm black egg wasp, and on the basis of being developed into another natural enemy of the masson pine caterpillar, improve the control effect to the masson pine caterpillar, reach the long-term protection of the masson pine forest, for further successfully controlling the masson pine caterpillar to Masson pine harm creates new avenues.

Description

technical field [0001] The invention relates to a method for improving the parasitism rate of the eggs produced by the wild silkworm black egg wasp parasitizing 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 t...
