A New Pheromone-Baited trap for Riptortus clavatus
Riptortus clavatus is one of the most serious pests affecting the cultivation of sweet persimmon, which is one of the most important export fruits in Korea. A pheromone-baited trap has been used in attempts to control this pest. Although the trap showed relatively good trap efficacy, it was often observed that R. clavatus walks around and rests on the surface of the trap rather than entering the trap. In the present study, the development of a more efficient pheromone-baited trap for R. clavatus was pursued by investigating 3 different traps: the fish trap, the pyramidal trap, and the symmetry trap. The fish trap captured the lowest number of R. clavatus, and the pyramidal trap showed moderate capture efficacy. Significantly greater numbers of R. clavatus adults were captured in the symmetry trap. Significantly increased trapping efficacy of the symmetry trap would be useful for mass trapping of R. clavatus.
