Problems solved by technology

The larvae are parasitic in the eggs of moths, so a class of natural enemies with great use value can be used for biological control of crops; but the Trichogramma breeding technology in the prior art results in parasitic eggs due to the operating environment, breeding process, storage and other processes. Problems such as low quality and low survival rate

Embodiment

[0017] The height of the breeding room should not be too high, about 2.2m, which is convenient for manual operation; the area should not be too large, 30m 2 Otherwise, once the natural enemies of the rice moth enter, it is not easy to deal with.

[0018] Layered wooden frames can be used for propagation. For ease of operation, it can be limited to 6 layers, and the specifications of each layer are:

[0019] 1.40m(length)×0.70m(width)×0.35m(height)

[0020] Because rice moth larvae will eat away at the wooden frame, it is best to replace it every 1 to 2 years.

[0021] 1.2 Environmental requirements

[0022] Cleaning: Before starting work, the breeding room and the raw materials (brown rice) used should be fumigated and sterilized for 1.5-2 days in a closed manner;

[0023] Density: During the disinfection period, the gaps between doors and windows should be sealed with adhesive tape to prevent air leakage and affect the disinfection effect; the screen window should be 80 me...

Abstract

The invention provides a technique for producing sugarcane Oophagous trichogrammae egg piece, including the following steps: propagation and collection of rice moth, collection of rice moth eggs, production of rice moth egg piece, ultraviolet irradiation and production parasitic bee piece. The technique provided by the invention has the advantages of strong operability, good quality and high survival of reproductive Oophagous trichogrammae, and can be used for large scale propagation and wide application.

Description

technical field [0001] The invention belongs to the field of biotechnology, and more specifically relates to a technology for making sugarcane Trichogramma egg slices. Background technique [0002] Trichogrammatid Any of small parasitic wasps of the family Trichogrammatidae (order Hymenoptera), especially of the genus Trichogramma, having adults less than 1 mm long and having pear-shaped, single-winged wings. Veins and spike-like ciliates, tarsus 3-noded, conspicuous. The larvae are parasitic in the eggs of moths, so a class of natural enemies with great use value can be used for biological control of crops; but the Trichogramma breeding technology in the prior art results in parasitic eggs due to the operating environment, breeding process, storage and other processes. Low quality, low survival rate and other issues. Contents of the invention [0003] The object of the present invention is to provide a technology for making sugarcane Trichogramma ovum slices. The tec...
