Duckweed pot type insect trapper

Abstract

The invention provides a duckweed pot type insect trapper which achieves the aims of reducing the population density in the fields and reducing harms to crops by trapping and killing pests via harmful insect pheromones. The trapper comprises a buoyancy trapping core box (1), a fixed rod insect fishing net (2), a trapping and killing pot (3) and pin supports (4), wherein a trapping core is arranged in the buoyancy trapping core box and is connected on a fixed rod in series; the fixed rod is connected with the insect fishing net by a screw and is arranged at the internal bottom of the trapping and killing pot; the pin supports play a role of supporting the trapping and killing pot; the trapping and killing pot is round; three overflow holes are arranged on the edge of the pot; the trapping and killing pot can be suspended and fixed by ropes when the trapping and killing pot is not easy to be supported by the pin supports; the buoyancy trapping core box can move vertically on the fixed rod along with lifting and dropping of the liquid soap level in the pot so as to ensure a fixed best trapping and killing distance between the trapping core and the liquid soap; the diameter of the insect fishing net is slightly smaller than the internal diameter of the trapping and killing pot; when the drowning dead insects are collected, the dead insects can be adhered to the insect fishing net and collected by vertically taking out the fixed rod directly; the upper ends of the pin supports are installed in installation holes at the external bottom of the trapping and killing pot; and fenders are arranged at the lower ends of the pin supports to avoid inclination when the pin supports are installed on the mellow soil.

Description

technical field [0001] The invention relates to a pest prevention and control device, which is a trapping and killing device for trapping and killing harmful insects through insect pheromones to reduce the population density of harmful insects in the field and reduce crop damage. Background technique [0002] At present, with the continuous improvement of our country's understanding of crops and food safety, various physical and biological methods of killing pests have emerged. Among them, the water basin trap device that uses insect-specific pheromones to trap and kill insects has been used for many years. However, the trapping efficiency of conventional water basin traps is greatly affected by the distance between the liquid surface in the water basin and the lure core and the liquid surface area. In high temperature seasons, it is necessary to frequently add the water level in the trapping basin to the specified position to effectively ensure the trapping rate; and some dr...

Problems solved by technology

However, the trapping efficiency of conventional water basin traps is greatly affected by the distance between the liquid surface in the water basin and the lure core and the liquid surface area. In high temperature seasons, it is necessary to frequently add the water level in the trapping basin to the specified position to effectively ensure the trapping rate; and some drowned Insects tend to sink to the bottom of the pot and are not easy to collect. Supported installation is not suitable for elevated crops, etc.
