Abstract
Abstract This study was examined for activity of aggregation pheromone fish net trap with residual effectof insecticides against Riptortus pedestris. Time of escape was from aggregation pheromone fish net trapresearched 49.74 min (ET 99 ) and 65.01 min (ET 99 ) with 1st and 2nd instar nymph respectively. Six insecticidesfor the stink bugs were treated to 3 different materials (wood, metal and plastic). Bifenthrin and fenitrothionwere showed 100% insecticidal activity at 48 h to all developmental stage of R. pedestris. Residual effect ofbifenthrin and fenitrothion on plastic material were showed 100% insecticidal activity over 15 day aftertreatment with 1st, 3rd instar nymphs and adults except 5th instar nymph. In field test using plastic material trapwith two pesticides, 1st instar nymphs and adults were showed 100% mortality until 10 day after treatment.These results indicate that R. pedestris might be managed using aggregation pheromone trap with insecticides.Keywords Riptortus pedestris, aggregation pheromone fish net trap, residual effect
