Sitotroga cerealella trap

Abstract

The invention discloses a sitotroga cerealella trap. The sitotroga cerealella trap comprises an upper cylinder body and a lower cylinder body, and the inner diameters of the upper cylinder body and lower cylinder body are 100 mm respectively; a spacer net is arranged in the upper cylinder body, the spacer net divides a cylinder inner cavity formed by the upper cylinder body and the lower cylinderbody into an upper cavity and a lower cavity, and the mesh diameter of the spacer net is 1mm; an air suction fan is arranged in the upper cavity, the bottom of the lower cylinder body is provided witha conical sealing bottom, the included angle between the conical surface of the conical sealing bottom and the cylinder wall of the lower cylinder body is 60 degrees, a small head end of the conicalsealing bottom faces the spacer net, the small head end of the conical sealing bottom is provided with an insect inlet of which the diameter is 10 mm, the vertical distance between the joint of the upper conical surface of the conical sealing bottom and the inner cylinder wall of the lower cylinder body and the upper edge of the upper cylinder body is 135 mm, and the lower conical surface of the conical sealing bottom is provided with a reflective layer; the lower portion of the lower cylinder body is provided with an insect attracting lamp bead, the lamp bead adopts a green light source witha wavelength of 530-575 nm, and an insect attractant is also arranged at the lower portion of the lower cylinder body. The sitotroga cerealella trap has an effective prevention and control effect on sitotroga cerealella and is free from pollution.

Description

technical field [0001] The invention belongs to the technical field of grain safe storage, and mainly relates to the prevention and control of stored grain pests, in particular to a wheat moth trap. Background technique [0002] The wheat moth is a stored product pest worldwide. It is widely distributed and can be found in many parts of our country. The wheat moth can harm a variety of food crops, including rice, wheat, corn, sorghum, etc., up to 19 species. The larvae of the wheat moth will be planted in the field with the crop seeds when sowing, and will break through the soil and fly when the temperature rises in summer. Studies have found that adults of wheat moths can also fly to the crops in the field to lay eggs, and then the larvae of wheat moths will enter the granary along with the grain harvest, and will continue to harm food crops in the granary. The wheat moth mainly affects the germination rate of food crops by eroding the embryo of the grain. The corn kernel...

AI Technical Summary

Problems solved by technology

At present, the problem of excessive dependence on chemical agents for the control of the stored grain pest Pest moth is still very serious, and the pollution-free control methods have not been widely used due to problems such as high cost and difficult implementation

With the continuous improvement of the level of pest control in storage, the disadvantages of some traditional control methods are gradually revealed. For example, long-term use of phosphine will cause various problems, including increased insect resistance, more rampant inferior pests, and pesticide residues. Areas that increasingly threaten food safety and environmental security
