Trapping device of cladoceran insects in crab pond and method of trapping device

Abstract

The invention discloses a trapping device of cladoceran insects in a crab pond and a method of the trapping device. The trapping device comprises a submerged pump and an undulating lamp, wherein the submerged pump is arranged in the crab pond in an inverted manner; the top ends of the submerged pump and the undulating lamp are respectively fixed on a fixed rod; a positioning rod is adopted for fixing the submerged pump and the undulating lamp; a water discharging pipe is arranged at the water discharging position of the submerged pump; a nylon filtering net bag sleeves the water discharging pipe. The trapping device disclosed by the invention has the advantages that by utilization of the principle of phototaxis of insects, the undulating lamp is fixed above the water surface of the crab pond, the submerged pump is erected under light, a suction opening of the submerged pump faces upwards, the submerged pump is inverted in water, the undulating lamp and the submerged pump are started at night, the insects gather together around the light, the insects near a pump opening are sucked into the submerged pump by the submerged pump and are discharged into the nylon filtering net bag by the water discharging pipe; the whole equipment is low in cost, and can be applicable to crab culture ponds, fish ponds and shrimp ponds; farmers have no need of using insecticides, so that the risk of investment and the insecticides is greatly reduced, no pollution or insecticide residue is caused to shrimps, crabs and fish, and the green and environment-friendly effects are achieved.

Description

Technical field [0001] The invention relates to a trapping device for insects, in particular to a trapping device for cladocerans in crab ponds and a method thereof, and belongs to the technical field of aquatic product breeding. Background technique [0002] There are more cladocerans in crab intensive ponds, which can easily cause white water, muddy water, and hypoxia, resulting in small crabs and low yields. Every year, crab farmers use a variety of drugs with high toxicity, long residues, and resistance to drug resistance, such as chrysanthemum, organophosphate, ivermectin, abamectin, etc., which greatly damage the environment and cause crabs. A large number of drug residues are formed, causing food safety hazards. Summary of the invention [0003] The technical problem to be solved by the present invention is to overcome the defects that too many cladocerans affect the yield of crabs, and the traditional deworming methods have a large impact on the environment and the defect...
