Problems solved by technology

In order to ensure the continuous control effect of Trichogramma on corn borer, the existing Trichogramma release devices and methods need to concentrate, repeat and repeatedly release Trichogramma during the egg-laying period of corn borer, so as to effectively protect corn plants from corn borer. corn borer damage; the Trichogramma eggs of the existing Trichogramma release device and method have a short shelf life and require special cold chain storage and transportation equipment, which greatly increases the cost of biological control of the corn borer

Abstract

The invention belongs to the technical field of pest biological control equipment, and particularly relates to a device and method for stabilizing the number of Trichogramma ostriniae in a field. Theinvention aims to reduce the release cost of Trichogramma, stably raise the population level of Trichogramma in a corn field, continuously reduce the population number of Trichogramma ostriniae in thefield, and finally improve the control effect of Trichogramma. The device comprises a wasp storage device, a connecting ring, a top cover and a control device. The device disclosed by the invention has the advantages that the structure is simple, the releasing cost of Trichogramma can be reduced, the population level of the Trichogramma ostriniae is stably raised, the field population quantity ofthe Trichogramma ostriniae is continuously reduced, and the control effect of the Trichogramma ostriniae is finally improved; the device can maintain the basic quantity of Trichogramma ostriniae in the field for long time, and reduce the hazard level of Trichogramma ostriniae, thereby reducing the number of releases of Trichogramma ostriniae, reducing the prevention and treatment cost and greatlyimproving the efficiency of biological control.

Description

technical field [0001] The invention belongs to the technical field of pest biological control equipment, and in particular relates to a device and a method for stabilizing the number of Trichogramma corn borer in the field. Background technique [0002] Corn is one of the most important grains in the world, and about one-third of the world's population uses corn as the main grain. Among food crops, the planting area and total output of corn rank third in the world. Corn borer is one of the most important pests harmful to corn growth. Corn borer larvae feed on corn leaves, stalks and ears, causing severe crop loss. Trichogramma is an egg parasitoid, and its hosts mainly include corn borer, cotton bollworm, tobacco budworm, cotton small bridge builder, small cutworm and other pests. Trichogramma plays an important role in the biological control of corn pests. In the process of corn planting, putting Trichogramma to control corn borer has the advantages of no poison to hum...
