The field of application is the field device entomology, especially research related catching insects in the study of arthropods, environmentally related to various substrates. The apparatus consists of a cylindrical reservoir and a trapping module, which is a truncated cone, whose height is less than twice the height of the collector, and which smaller base inserted into the reservoir. The diameter of the greater base of the trapping module is equal to the diameter of the reservoir, so that the module is held in it. The module has a lid, centered on the inwardly facing opening for the fixed funnel, the height of the cone which corresponds to the module height and on the periphery - sectoral hole tightened fine-mesh metal net to spread odor bait placed inside. Trapping module cover is fixed with a washer, a screw on the outside of the funnel spout to be inserted into a hole in the bottom of the module. Insects, attracted by the smell of the bait, searching, access to fall through a funnel into the collector with the fixing fluid, from which is then selected using a small screen or a net.
