46 NOVEMBER 2016 GOOD FRUIT GROWER www.goodfruit.com R esearchers from Washington State U n i v e r s i t y , t h e W a s h i n g t o n S t a t e Department of Agriculture and the U.S. Department of Agriculture-Agricultural Research and Extension continue to monitor the expanding distribution of the invasive brown mar- morated stinkbug (BMSB). By the end of 2015, BMSB was found in 16 Washington counties, primarily along the interstate corridors. In early 2016, BMSB was confirmed in another three counties as the range of this stinkbug continues to expand. There are reports of BMSB causing significant crop damage to tree fruit and vegetable crops in the Atlantic Seaboard states, but no confirmed reports of BMSB dam- age to crops in Washington. Nevertheless, Northwest researchers (similar efforts are underway in Oregon) are concerned that the abundance of BMSB may continue to build and are hopeful that fruit producers can adopt and implement management strategies before crop damage is confirmed in the region. There have been a number of research and commer- cial trap designs that use stinkbug pheromones to lure stinkbugs into the traps. Peter Landolt, Ph.D., (USDA- ARS, Wapato) and WSU collaborators have experimented with numerous combinations of these traps with the goal of finding the best means of monitoring BMSB. In one trial, the Rescue Wasp Trapstick baited with BMSB lures produced by Sterling International captured more BMSB in one trap at one Yakima, Washington, location in 24 hours than all BMSB captured in Yakima County in 2015 and 2016. Over the next month, we will continue to mon- itor BMSB and confirm the efficacy of this potential new trap design as a monitoring tool. In 2017, monitoring of BMSB will continue in GOOD TO KNOW Using smell to battle stinkbug Researchers using pheromones to lure stinkbugs find some traps work better than others. by Michael Bush PHOTOS BY TJ MULLINAX/GOOD FRUIT GROWER Entomologist Peter Landolt holds a commercial pheromone attractant for brown marmorated stinkbug that he used along with a common sticky wasp trap.
