In a field experiment at Yigo, plastic bucket traps baited with the lure of the Australian R. obscurus population in combination with ethyl acetate and cut sugarcane captured significantly more weevils than traps baited with pheromone + ethyl acetate, pheromone + sugarcane or individual lure components alone. Traps baited with various semiochemical-based lures and treated with insecticide captured significantly greater numbers of weevils than those not treated with insecticide. Traps baited with cut sugarcane caught significantly more weevils than those without sugarcane. Semiochemical-based trapping in weevil management has potential either in mass trapping or as part of an integrated pest management (IPM) programme.

In a field experiment at eight different locations (Dededo, Tumon, Yigo, Hagåtña, Mangilao, Yona, Agat and Malesso), plastic bucket traps baited with the lure of the Australian R. obscurus population in combination with a food volatile compound (ethyl acetate) and cut sugarcane captured significantly more weevils (total of 348) than traps baited with pheromone lure of the Hawaiian R. obscurus population in combination with food volatile and cut sugarcane which caught a total of 128 weevils. Traps baited with lure containing only the food volatile and cut sugarcane or only cut sugarcane captured significantly fewer weevils (total of 36 and 30, respectively) than those baited with pheromone compounds. Data from trap catches indicate that the Guam population of R. obscurus responded significantly more to the pheromone lure of the Australian population than to pheromone lure of the Hawaiian population indicating that the Guam R. obscurus population is related more closely to the Australian population. Trap catches at the Tumon and Dededo locations were greater than those in Yigo, Yona, Mangilao, Hagåtña, Agat, and Malesso. Rainfall had a low correlation with trap catches at all locations except at Yigo where it positively correlated to the Australian population lure treatment. Semiochemical based trapping in weevil management has potential either in mass trapping or as part of an IPM program. A future line of work is also proposed for the control of weevil borers based on these initial results.10aDryophthoridae10aRhabdoscelus10aRhabdoscelus obscurus1 aMUNIAPPAN, R.1 aBAMBA, J.1 aCRUZ, J.1 aREDDY, G., V.
