Description

Dart bee-releasing device

Technical Field

The utility model belongs to the field of biological control of sugarcane pests, and particularly relates to a dart bee-releasing device.

Background

The crops of the sugarcane serving as industrial sugar production raw materials in China are easily affected by various insect pests in the planting process, especially the damage of the stem borers of the sugarcane is caused, the yield of the sugarcane can be reduced by 10-15% and the sugar content of the sugarcane can be reduced when serious.

The adoption of biological control can effectively avoid a series of problems caused by chemical control, not only optimizes the ecological environment, but also is safe and harmless to producers and consumers, and simultaneously can greatly reduce the use of pesticides, thereby providing an eco-friendly alternative scheme for the treatment of plant diseases and insect pests. Trichogramma is a biological natural enemy of lepidoptera pests with the widest application range in the world, the use amount of chemical pesticides can be effectively reduced by utilizing trichogramma for pest control, the drug resistance of the pests can also be reduced, and the trichogramma control technology becomes an important measure in the field of biological control and has great application and popularization values.

The traditional method for releasing trichogramma in the field is to put the trichogramma cards containing trichogramma eggs and various spherical releasers in the field, and manually putting the trichogramma cards on sugarcane plants one by sticking the trichogramma cards on the ground. The throwing mode wastes a large amount of labor force, is low in working efficiency and longer in throwing time, and can influence the pest control effect if the throwing time of trichogramma eggs is too long. The use of unmanned aerial vehicles to mass-launch natural enemy insects such as trichogramma and the like for pest control is a means for recent years. Trichogrammars are put in by using the unmanned aerial vehicle, and can be operated and completed by a few professionals, so that natural enemy insects can be evenly and timely and effectively put in the field, the mode of manually putting trichogrammars in the past is changed, manpower and material resources are saved, and the working efficiency and the control effect are improved. When unmanned aerial vehicle is put in, if the bee card with trichogramma eggs is directly put in the field, the eggs lack protection and are easy to be damaged by feeding by ants and other organisms, or the trichogramma cannot emerge due to the influence of high temperature and overcast weather, so that the effect cannot be exerted. The existing unmanned aerial vehicle-based throwing device mostly takes a spherical releaser for storing trichogramma eggs as a throwing object, the releasing ball is lighter, the throwing process from the air to the field is easily interfered by external factors, the movement track is unstable, and a larger throwing error is caused. In the southern area, in high-temperature weather where pests are high, the surface temperature is often over 40 ℃, when trichogramma balls are put in, the trichogramma balls die in a large quantity when the surface temperature is higher than 38 ℃ because the spherical releaser is tightly attached to the ground. Such as trichogramma release ball of patent No. 202021313789.3.

In addition, we have also found other biological agent containers, such as:

application number: 201611121798.0, name of utility model: a cylindrical biological agent container comprising: a cylinder; the adhesive sheet is arranged in the cylinder, adhesive agents are arranged on two surfaces of the adhesive sheet, and the width of the adhesive sheet is larger than the inner diameter of the cylinder; and the upper top cover and the lower top cover are fixedly connected with the two ends of the cylinder, a plurality of round holes are formed in the position, close to the center of the circle, of the upper top cover, and the upper top cover and the lower top cover are identical in structure. The utility model has small volume and light weight, the lower top cover of the upper top cover is provided with the corresponding round hole, the size design of the round hole can ensure that the hatched trichogramma flies out, and meanwhile, the trichogramma can prevent natural enemies such as ants from entering, prevent internal temperature from rising caused by sun insolation, has a rainproof function, is suitable for manual throwing or automatic sowing of aircrafts, can ensure uniform sowing, but the throwing device is easy to damage a throwing component due to faster descending speed in the throwing process.
