Description

A device for trapping and killing crop pests and releasing natural enemy insects

technical field

The utility model belongs to the technical field of physical control of crop pests, and in particular relates to an integrated device for trapping and killing pests such as Noctuidae adults and releasing natural enemy insects such as ladybugs, Trichogrammas, and predatory mites.

Background technique

Establishing and improving green prevention and control technologies for crops such as flue-cured tobacco, vegetables, and fruits, and building a long-term mechanism for green ecological planting of crops are of great significance to improving the environment, safety of agricultural products, and promoting the sustainable, stable and healthy development of the industry. In recent years, the occurrence area of vegetables, flue-cured tobacco, and fruit tree pests has continued to expand, causing huge economic losses, seriously reducing production by more than 50%, and even causing crop failure. For many years, we have mainly relied on chemical pesticides to control pests. The abuse and excessive use of pesticides not only caused a sharp increase in the resistance of pests, but also killed a large number of natural enemy insects, caused serious pollution to the ecological environment, affected the safety of crop products, and posed a serious threat to human survival and safe production of crops. Natural enemy insects are the natural control factors of pests in the crop system. Using the concept of mutual generation and restraint in nature to control pests can effectively overcome the disadvantages of chemical pesticides and improve environmental and food safety. Therefore, many scientific and technological workers combine physical and biological natural enemies Control technology is widely used in crop green planting. However, the pest traps and natural enemy insect release devices currently widely used have relatively single functions, and have disadvantages such as high cost of use, cumbersome operation, difficulty in reusing, and low control efficiency. In addition, although paper release devices are environmentally friendly and low in cost, they are The release field is prone to mildew due to the influence of climate, which is not conducive to the hatching of natural enemy insect eggs. Therefore, the development of a device that integrates pest trapping and natural enemy insect release can not only solve the above-mentioned disadvantages, but also have great significance for reducing labor intensity, energy saving and environmental protection, and improving the green and ecological control effect of crop diseases and insect pests.

detailed description

The utility model will be further described below in conjunction with the accompanying drawings.

Crop pest trapping and natural enemy insect releasing device as shown in Figure 1-3, comprises columnar and has the pest trapping chamber 2 of funnel bottom, is arranged on the two half columnar natural enemy insect releasing chambers 3 below trapping chamber 2, is arranged in releasing chamber Below and the pest collection bag 4 that communicates with the trapping chamber, the top cover 1 that covers the trapping chamber top. The center of the bottom of the funnel of the trapping chamber 2 has a downwardly extending external threaded worm tube 5, and the side wall of the trapping chamber 2 is provided with a tapered trapping hole 6 that is large outside and small inside and is suitable for adults to enter. Hole 7, binding hole 13. The two half-column natural enemy insect release chambers 3 are placed on the release chamber base 8, the opposite walls of the two release chambers 3 are provided with an insect outlet 14 and there is a gap between the two wall surfaces, and the center of the release chamber base 8 has a The internally threaded connecting pipe 9 that can be screw-mounted on the trapping outdoor threaded lower worm pipe 5, the top surface of the release chamber 3 is an open structure without a cover, and the internally threaded connecting pipe 9 is unscrewed on the externally threaded lower worm pipe 5.
