Problems solved by technology

However, in the process of artificial breeding of Scleroderma guanii, it was found that the host self-bitten or was infected, causing the body to turn black and die seriously. The dead host could not be parasitized by Scleroderma guanii. breeding cost

Embodiment Construction

[0018] The present invention will be further described below in conjunction with specific examples.

[0019] A method for improving the reproductive success rate and reproduction quantity of Scleroderma guanzi, comprising the following steps:

[0020] (1) Selection of longhorn beetles: long-term beetles with normal stretching, no stiffness at the last segment of the tail, and no wounds or black spots on the body surface were selected as the candidate hosts.

[0021] (2) Cleaning the body surface: put the beetle in a clean plastic screen frame, knead the toilet paper into a loose spherical shape, place it on the top of the beetle's body surface and wipe it gently, driving the beetle to roll, and wipe off the beetle's body surface Attached moisture, sawdust, excrement, etc.

[0022] (3) Alcohol disinfection and sterilization: select a larger container, pour 3 times the volume of longicorn beetles in 75% alcohol, pour the longicorn beetles into the alcohol, stir gently with blun...

Abstract

The invention relates to a technology for increasing the breeding success rate and breeding quantity of sclerodermus guani. A suitable body surface disinfectant, a suitable treatment method and suitable disinfection time are selected, the longicorn infection rate is effectively reduced, and the breeding success rate and the breeding quantity are increased. Compared with a control group, the breeding success rate of longicorn treated with the technology is increased by 24.88%, the proportion of longicorn with the breeding quantity exceeding 50 is increased by 13.56%, and the breeding success rate and breeding quantity of sclerodermus guani are effectively increased.

Description

technical field [0001] The invention relates to a breeding method for parasitic wasps in vitro, in particular to a technique for improving the breeding success rate and breeding quantity of Scleroderma guanidei. Background technique [0002] Scleroderma guanidei belongs to the family Sclerodontidae of the order Hymenoptera, and is an ectoparasitic natural enemy insect of a variety of long-beetle borer pests. Longhorn beetle insects are important tree-boring pests, mainly causing damage by larvae eating tree trunks, branches or roots. The seriousness of the damage has brought huge economic losses to the society and seriously affected China's afforestation projects. Desertification prevention and urban greening construction. Because long-term beetle larvae are inside the host, the control is relatively difficult, and it is often difficult to achieve the desired effect. The application of natural enemies has been paid more and more attention. Among them, Scleroderma guanidei ...
