Novel trapping device based on population dynamics of solenopsis invicta

The invention relates to the technical field of solenopsis invicta catching, in particular to a novel trapping device based on solenopsis invicta population dynamics, which comprises a trapping frame, a trapping module for catching solenopsis invicta is mounted in the trapping frame, and a downward moving module for squeezing the solenopsis invicta into the trapping module is arranged above the trapping module. One side of the inner wall of the trapping frame is fixedly connected with a feeding module used for feeding food, the other side of the inner wall of the trapping frame is fixedly connected with a controller and a fixing block which are distributed up and down, an air pump is fixedly connected above the fixing block, the output end of the air pump is communicated with an exhaust pipe, and the bottom of the exhaust pipe is slidably connected with a movable sleeve; according to the device, the trapping frame is buried in the soil layer, the solenopsis invicta can conveniently enter the trapping bottle t
