A mating disruption experiment to control Melanotus okinawensis Ohira (Coleoptera: Elateridae) was conducted at a sugarcane (Saccharum spp.) field and wild Japanese pampas, Miscanthus sinensis Anderss, grassland on Minami-Daito Island (3,057 ha) from 2001 2007. The the pampas were treated with synthetic sex pheromone that evaporated polyethylene tube dispenser. mean total catches obtained by monitoring traps in fields decreased 96.1% previous year Island. trap area further 74.0% until 2007 as cumulative effects. Simultaneously, number of adults captured hand 4.7 per 0.5 (89.3% reduction), whereas those untreated (Miyagi Island) did not show such decrease. rates significantly lower females (14.3–71.4%) than (96.9–100%). However, amount decrease relatively small first (39.6% reduction) periphery This probably due loss substance caused strong seasonal wind periphery. also within several years; significant decreases detected 2003, 2006, These results indicated effectively reduced an isolated population M. okinawensis.
