We compared the trapping efficiencies of a pheromone trap developed in 2012 in Japan (TRIOS® for Trogoderma granarium, Fuji Flavor Co., Ltd.) and a foreign-made pheromone trap (DOME ™ Trap for T. granarium and T. variabile, Trécé Inc.) for T. granarium adult males. The trap was placed in a plastic container (W55.0 x D38.4 x H4.1 cm inner dimensions) and 50 T. granarium adult males were released. After 48 h the captured adults were counted. The capture rates were 88.8% for the TRIOS® and 58.6% for the DOME ™ Trap, thus revealing a significantly higher trapping efficiency with the TRIOS® than with the DOME ™ Trap.
