It is right from the above description that the structure of the present invention is described, compared with the prior art, the present invention has the following advantages:
1. the pest trapping device with the structure is characterized in that the fan and the fan shell are additionally arranged between the trapping lamp and the pest collecting box, wherein the top end of the fan shell is provided with an airflow inlet opposite to the trapping lamp, the bottom end of the fan shell is provided with an airflow outlet communicated with the inside of the pest collecting box, when the fan works, a large negative pressure is formed on the trapping lamp, pests on the periphery of the trapping lamp can be sucked into the pest collecting box, the airflow is discharged from the air holes in the surface of the pest collecting box, and the pests are left in the pest collecting box. So the utility model discloses a pest trapping device can prevent that the pest adhesion is on trapping the lamp surface, has improved the efficiency of traping of grain face pest.
2. The trapping device of this structure, the trapper top is inserted to album worm incasement, and the top surface is made by transparent material and is higher than album worm case bottom surface, because the air current casing of fan casing is just to the trapper top surface, can prevent that the pest from piling up at the trapper top surface, is convenient for in trapper light penetrates transparent material and jets into the trapper, is favorable to trapper to phototaxis pest's traping, improves the efficiency of traping of grain in-pile pest.
3. The trapping device with the structure can trap pests on grain surfaces and in grain piles respectively, and collect the pests in the pest collecting box and the trapping device correspondingly, namely, the pests are physically isolated. The method can be used for calculating the insect pest density and helping accurately judge the insect pest condition in the grain surface and the grain pile.
