Trapping efficacy of funnel-vane and water pan traps baited with synthetic sex pheromone of the sugarcane wireworms, Melanotus sakishimensis Ohira and M. okinawensis Ohira (Coleoptera: Elateridae), were investigated in sugarcane fields on Miyako Island and Okinawa Island in 1998. Funnel-vane traps captured significantly more males of both M. sakishimensis and M. okinawensis than did water pan traps.
