Background:
The khapra beetle, Trogoderma granarium, is a serious pest of stored grains that infests more than 100 different commodities. The current wall trap used for monitoring is optimized for the behavior of khapra beetles. In this study, we tested existing and modified trap designs for Trogoderma after release of T. granarium exclusively. The work aimed to evaluate trap efficacy, while providing a template for further attract-and-kill research. Three bioassays were conducted in nine rooms. Four traps were evaluated: dome, wall, modified wall, and the Wilkins interception trap.
Results:
Based on our results, dome traps collected significantly more individuals compared to the other traps, whereas the modified wall and Wilkins traps collected significantly fewer individuals compared to the dome trap. Regarding progeny production, the highest number of individuals was found from a release distance of 0.1 m. The highest number of individuals was captured at 0.1 m.
Conclusions:
The most effective trap was the dome trap. The plume reach and distance from the trap/attractant source is an important parameter that can affect trapping efficacy in monitoring programs. © 2025 The Author(s).
