BIOLOGY, DISTRIBUTION AND PEST STATUS OF THE BROWN MARMORATED STINK BUG IN AGRONOMIC, FRUIT AND VEGETABLE CROPS, AND URBAN AREAS

Project Details

Description

The brown marmorated stink bug, Halyomorpha halys Stal (BMSB), is a highly polyphagous stink bug of Asian origin. In its native range of China, Korea and Japan, it is considered an agricultural pest of soybeans, apples and other tree fruit and various ornamental crops. BMSB is also a nuisance pest in these countries due to its overwintering behavior of entering enclosed structures such as residences in large numbers each fall. BMSB was first observed in the US in Allentown, PA around 1996 but was initially misidentified as a native pentatomid species. Following correct identification in 2001, it has been found in several Northeast and Mid-Atlantic States and in CA, FL, OH, OR, TN and MS. In several of these states, its presence in agriculture crops has been confirmed and has been observed causing late season damage to apples and pears in NJ, PA, and WV. Traditionally, management of stink bugs in soybeans, tree fruit and horticultural crops was accomplished through the use of targeted applications of organophosphate insects. However, these materials have been slowly phased out resulting in increased damage by stink bugs. The addition of BMSB with its high rates of reproduction and survival puts these crops at greater risk. In the laboratory, replacements for organophosphate insecticides exhibit high levels of toxicity to BMSB but have not tested under field conditions. In Asia, BMSB is attacked by several egg parasitoids and a tachnid fly. Little information is known however, about endemic natural enemies in the US. The use of microbial agents is another potential non-chemical control method but again no screening for possible candidates has been conducted. BSMB has become a severe residential nuisance pest wherever it occurs. Currently, there are no adequate pest management alternatives to prevent overwintering BMSB adults from entering residences in areas where they occur. The use of insecticides to control BMSB has proven effective in Japan; however, this usage is not currently labeled in the US and is not currently an option. A non-insecticidal management method is the potential use of mass trapping. If successful, residents in PA, NJ, MD, DE VA and elsewhere where BMSB occurs will directly benefit due to reductions in illegal pesticide use, a reductions in potential environmental problems, and reductions in entomophobia and exposure to pesticides by affected homeowners thereby improving their health and decreasing calls to county cooperative extension offices and other agencies. These issues make it imperative that research be conducted this year in order to begin development of management strategies. This importance is highlighted by PI's Leskey and Hamilton having received a NE IPM Center grant to form a BMSB working group charged with identifying current abilities and research needs. Therefore, we propose to 1) investigate the biology of BMSB on and the potential susceptibility of soybeans, apple, peach and pear to feeding by BMSB, 2) determine the current and projected distribution and pest status of BMSB on soybeans, tree fruit and peppers, and 3) develop and evaluate various BMSB management strategies.
