Abstract

The invention provides a method for breeding trichogramma japonicun ashmead by means of beet armyworm ovums. The method is relatively high in production efficiency and short in breeding period, and is beneficial to scale production of trichogramma japonicun ashmead. The method comprises following steps of 1) producing beet armyworm ova; and 2) breeding trichogramma japonicun ashmead by means of the beet armyworm ova. The trichogramma japonicun ashmea bred artificially are used for controlling agricultural pests which mainly comprise rice-stem borer, yellow rice borer and rice leaf roller. Compared with the prior art, the trichogramma japonicun ashmead artifical breeding production method is advantaged in that beet armyworm can be obtained easily, and can be bred simply; and the method is relatively high in production efficiency and short in breeding period, and is convenient for large-scale breeding, and is beneficial to scale production of trichogramma japonicun ashmead.

Description

technical field

[0001] The invention belongs to the technical field of biological control of agricultural pests, and relates to a breeding and production method for Trichogramma, in particular to an artificial breeding and production method for Trichogramma rice borer. Background technique

[0002] Trichogramma is the most researched and most widely used insect in biological pest control in the world. At least 12 species have been artificially propagated in large numbers to control some important agricultural and forestry pests. The mass breeding of Trichogramma population is mainly carried out by using intermediate host eggs, and the intermediate host eggs of Trichogramma are relatively successfully utilized are tussah silkworm eggs, castor silkworm eggs, wheat moth eggs and rice moth eggs. Large eggs (tussah silkworm eggs, castor silkworm eggs) are easy to obtain and relatively low in cost, so large-egg bees bred with tussah silkworm eggs such as Trichogramma pine caterpil...
