Abstract: Japan Mitsui Toatsu is making efforts to develop a market for Trebon as a sanitary pest insecticide. Trebon has high activity against various insect pests and remarkably week toxicity to mammals. The Trebon 20 WP was applied to the upper surfaces of the differcut panels. Bioassay test performed under laboratory conditions using contact method. The glasses and painted wood panels at 30 or 100 nag a.i/m² were all effective for 90 days to Culex pipiens pallens, Musca domestica and Blattella germanica. When applied to the surface of plaster, residual efficacy of Trebon (100 nag a.i/m²) was achieved up to 60, 90 and 15 days to mosquitoes, houseflies and cockroaches respectively. In the 41.2m² test room treated 100 mg a.i/m² Trebon, the lasting period of 100% mortality against Mosquitoes, Houseflies and cockroaches was over 90 days.
