| Summary: | The brown marmorated stink bug, Halyomorpha halys (Stål) (BMSB) is an exotic invasive insect originating in East Asia, currently causing significant damage to fruits, vegetables and other crops throughout most of the Mid-Atlantic states of the U.S. It also is a nuisance pest, entering homes in the fall in search of suitable overwintering sites. Two formulations of BotaniGard® with a strain of Beauveria bassiana (GHA) as the active ingredient were tested against second instar BMSB. Both the wettable powder and the emulsifiable suspension formulations were efficacious at 1 × 107 conidia mL−1, causing 67%–80% mortality 9 days post treatment and 95%–100% after 12 days. The wettable powder formulation was slightly more efficacious. |
