The rice and the sugarcane are used as two crops of grains and industrial sugar-making raw materials in China, and the yield and the quality of the crops are easily influenced by various insect pests in the planting process, particularly the damage of borers, so that the sugar content of the sugarcane is reduced, and the yield of the sugarcane and the rice is reduced.

In order to realize biological insect prevention in the field, people throw the trichogramma releaser to the field in a scattering type in a large scale through an unmanned aerial vehicle, so that the aim of controlling insects by bees is fulfilled. The method is an advanced method with high efficiency and environmental protection for preventing and treating the insect pests of the sugarcane and the rice borer. At present, green biocontrol technology for preventing and controlling sugarcane borers and rice borers by trichogramma is developed on a large scale in sugarcane fields and paddy fields at home and abroad. The principle of releasing trichogramma in a field is that trichogramma parasitic eggs are placed in a releaser and thrown into the field, the trichogramma parasitic eggs in the releaser grow into trichogramma and then fly outwards to search for borer eggs for parasitization, so that the borer eggs cannot grow into insect pests and die, and the effect of controlling insects by the trichogramma is achieved. The release performance is critical.

The existing method for releasing trichogramma in field adopts paper release card and various spherical releasers. In the practice of releasing trichogramma, we carry out a release test on trichogramma and test the bee releasing effect of various releasers, and the result is that: in the field of southern areas, parasitic eggs of trichogramma cannot reach the goal of stably feathering and producing trichogramma, and partial release fails.
