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

experiment example 1

[0051] Experimental example 1. The selection of the wavelength of the light source used by fluke lamp beads

[0052] There are many factors that affect the phototaxis behavior of the wheat moth, among which the wavelength of the light source is the most important. Selecting a light source with a specific wavelength range is conducive to targeted trapping of pests, thereby improving trapping efficiency. Due to the nature of insects, they have different tropism or avoidance to different light sources, and different insects also have different choices for the tropism of light waves. The wheat moth shows different tropisms to different light source wavelengths. We need to find out the wavelength with the strongest tendency to the wheat moth as the wavelength of the light source for the trap. Finding out the specific wavelength range of the wheat moth is beneficial to targeted traps. A light trap for wheat moth is designed to improve trapping efficiency.

[0058] Experimental example 2. Determination of the diameter of the insect inlet of the conical bottom cover and the slope of the conical surface of the conical bottom cover

[0059] 1. The diameter of the insect inlet of the tapered bottom cover

[0060] The different diameters of the tapered bottom cover insect inlets will affect the efficiency of the trap, because too large diameter may cause the wheat moths that have entered the collection area to escape again, thereby reducing the trapping efficiency. If the diameter is too small, it will make it difficult for wheat moths to enter the collection area of ​​the trap, and some wheat moths may not be able to enter the insect mouth, thereby affecting the efficiency of the trap. Therefore it is also critical to determine the diameter of the tapered bottom cover insect inlet.

[0061] Experimental process: 50 wheat moths were placed in a closed cuboid darkroom of 120×100×100 cm. Make three traps. The difference between the thr...

experiment example 3

[0075] Experimental example 3. Determination of the mesh diameter of the partition

[0076] In order to prevent the trapped wheat moth from falling into the suction fan from the screen mesh and affect the operation of the fan, it is necessary to ensure that the diameter of the screen mesh is less than the minimum body width of normal wheat moth adults. Therefore, it is necessary to determine the diameter of the mesh mesh.

[0077] Experimental process: Randomly capture 100 adult wheat moths from the test insects with an insect collecting tube, divide the captured wheat moths into 10 groups, and put 10 adults in each group, and put them into ten insect collecting boxes. Extrusion death will deform the body width of the wheat moth, put the insect collection box in the refrigerator to freeze to death. Put the dead wheat moth body under the microscope, take a graduated ruler and place it under the dead wheat moth, adjust the position of the microscope close to the ruler, so that ...

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...
