Embodiment Construction

[0034] Below in conjunction with accompanying drawing, the present invention will be further described.

[0035] figure 1 As shown, it is the flow chart of the existing Trichogramma production and reproduction process. The existing Trichogramma production and reproduction needs to go through the process of 4 rice moth egg killing, which is an important bottleneck point that affects the improvement of Trichogramma production efficiency. Rice moth egg embryo, in order to avoid going out worm, just can make Trichogramma parasitize and proliferate in rice moth egg.

[0036] figure 2 As shown, it is a schematic diagram of killing embryos according to the UV lamp on one side of rice moth eggs laid on the existing tray. image 3 Yes figure 2 Schematic diagram of the structure cut along the A-A line. The combination of the two figures shows that the existing method of killing rice moth eggs is to use stainless steel trays to flatten rice moth eggs, and to kill the embryos by irra...

Abstract

The invention discloses a rice moth egg double-sided embryo killing method, comprising a rice moth egg double-sided embryo killing cabinet. The method is characterized by also comprising steps of freezing egg carrying boards, forming a basal plate water film, making egg carrying boards, and irradiating to kill embryos. The method makes density of a rice moth egg formed on the egg carrying board reach 300 ml / m<2>, and rice moth egg handling capacity is 3.75 times of density of an artificial spawning method. Since double surfaces of the basal plate can be used, coated rice moth eggs are 7 times of an original method on a same-area basal plate, and coating operation time is reduced by 70%, so productivity is greatly improved. The method is simple and rapid in rice moth egg coating operation, and stable in effect. Rice moth egg coating density is large, close to theoretical density. An ultraviolet lamp irradiation device is simple in structure, and the method is suitable for different production scales. The method advantaged by high embryo killing efficiency, and is suitable for present requirement of trichogramma expanding propagation production.

Description

technical field [0001] The invention relates to a method for breeding and producing Trichogramma and a method for killing embryos of rice moth eggs. Background technique [0002] Sugarcane is widely planted in southern my country as a raw material for industrial sugar production. In the process of sugarcane planting, the yield and quality of sugarcane are most affected by the attack of sugarcane borer. Severe pests can reduce the yield of sugarcane by 10-15%, and the sugar content of sugarcane will drop by 3-5%. In order to obtain a stable and bumper harvest, large-scale production of Trichogramma to control sugarcane borer is gradually carried out in southern my country. Trichogramma is used to control sugarcane borers because biological insect control has better pest control effect than chemical insecticides, and has no adverse effects on the natural environment. [0003] Trichogramma is a small parasitic wasp, usually less than 1 mm in length, named for its red monocula...
