A kind of high-efficiency propagation method of Trichogramma rice borer

Abstract

Provided is a trichogramma japonicum high-efficiency reproduction method. The method comprises: collecting eggs of rice moths, and sticking the eggs on paper boards to make egg cards; putting trichogramma japonicum species and eggs of rice moths in a darkroom in proportion of 1:10 to 1:4, adjusting bee species emergence parasitic environment temperature to 23 to 25 DEG C, adjusting humidity to 70% to 80%; after 90% of the egg cards have parasitic bee species, adding fresh rice moth egg cards according to 1:6-10 of proportion of the bee species and the egg cards again, properly increasing temperature of the darkroom to 25 to 28 DEG C, and maintaining the humidity; after more than 90% of the egg cards have parasitic bee species, adding fresh rice moth egg cards according to 1:3-7 of proportion of the bee species and the egg cards for the third time, the egg cards this time being sprayed with cane sugar nutrient solution, the bee species continuing to reproduce. The method can realize using the trichogramma japonicum to prevent rice leaf folders and striped rice borers, and pesticide dose is greatly reduced. The method promotes agriculture to develop towards green, organic, and ecological agriculture.

Description

technical field [0001] The invention belongs to the technical field of biological control of rice diseases and insect pests, and in particular relates to a high-efficiency breeding method for Trichogramma rice borer. Background technique [0002] The rice borer Trichogramma belongs to Hymenoptera, Trichogramma, likes to live in rice fields or similar swampy environment, and can parasitize some species such as Chiropteridae, Noctuidae, Noctuidae, Pleurophyllidae, and Diphtheridae The eggs of insects are also natural enemies in the egg stage of major rice pests such as the rice borer, the rice leaf roller, the rice borer, and the rice bract moth, and have a certain control effect on the occurrence of rice field pests. [0003] The Ministry of Agriculture proposes that by 2020, my country's agriculture will achieve "one control, two reductions and three basics". In terms of pesticides, it is necessary to promote the unified control and green control of crop diseases and insect ...

AI Technical Summary

Problems solved by technology

[0005] The technical problem to be solved by the present invention is to provide a high-efficiency breeding method for Trichogramma rice borer in view of the large-scale use of chemical agents in the southern rice production process, in order to realize the control of Trichogramma rice borer in large areas. borer and stem borer, greatly reducing the amount of chemical pesticides used in southern rice fields, and promoting the development of my country's agriculture to green agriculture, organic agriculture, and ecological agriculture
