Cody Holthouse collects brown marmorated stink bugs (BMSB)

Mark Cody Holthouse, PhD student co-advised by Drs. Diane Alston and Lori Spears, was awarded a $25,000 graduate student grant to study a relatively new invasive insect pest in Utah, the brown marmorated stink bug (BMSB). BMSB is an economically important nuisance and agricultural pest that invaded North America from eastern Asia. Adults congregate in and on buildings during the winter, and attack a wide range of plants, including fruit and vegetable crops during the growing season. Funded by the USDA Western Sustainable Agriculture and Education program, Mr. Holthouse will study the host plant range utilized by BMSB in Utah, determine its phenology and voltinism (development and life history), and assess the effectiveness of native natural enemies, including entomopathogens and egg-parasitizing wasps in suppressing BMSB populations.
