Adult brown marmorated stinkbugs overwinter in structures and move out in the spring to lay eggs. Eggs are laid in masses of 28 and deposited on the underside of leaves. In northern locations, the pest has one generation, but OSU's research found that two generations were possible in Oregon. Bad news "That's really bad news," Wiman said. "Stinkbug populations have the potential to grow faster than we originally thought in the Pacific Northwest." Another problem with trapping is placement. "We know little about where is the best place to put the traps," he said. "We've had traps out that don't catch anything, yet we find stinkbug in the field." Dr. Peter Shearer, OSU entomologist, is leading the West Coast component of the brown marmorated stinkbug research. One of Shearer's priorities is to improve trapping and monitoring techniques. In addition to developing a better trap, Shearer and the team of scientists are exploring other areas: — Developing condos that could attract and kill the stinkbug in urban and rural settings — Using lighted traps at night to attract stinkbugs — Finding effective, new chemicals — Determining the most active time of feeding — Determining when the pest moves in and out of crops — Learning if there is an optimal time to make insecticide applications "For now, we're not recommending that growers use pheromone traps on brown marmorated stinkbug because we don't know what it means if you catch some or not," Shearer told Good Fruit Grower. "We need to be able to relate the number of bugs in the trap to damage in the field so growers know what to do with the trap information." However, he's optimistic an effective trap soon will be available to growers. • Introducing Madex HP for control of codling moth and oriental fruit moth larvae.
