An invasive agricultural pest that can cause extensive damage to crops has been discovered in Kelowna, the second confirmed sighting in the Okanagan.
The bug can be devastating to tree fruits, berries, grapes, vegetables and ornamental plants.
The ministry has conducted outreach to growers and the general public for brown marmorated stink bugs since 2010. It is increasing 2017 efforts through a multi-agency surveillance and monitoring plan, after the bugs were found in B.C. for the first time in 2016. A few were identified in Penticton in the spring and summer, and several more in the Kitsilano area of Vancouver and Chilliwack. The bugs are excellent hitchhikers and can be moved in shipping containers, wood, wood-packing material, cargo and vehicles
The bug does not pose a risk to people, but can be devastating to tree fruits, berries, grapes, vegetables and ornamental plants, and a nuisance to homeowners as the adults aggregate on and in buildings while seeking warm overwintering sites.
The brown marmorated stink bug, a native pest of Asia, was first identified in North America in Pennsylvania in 2001. It has since spread throughout the mid-Atlantic states and is present in California, Oregon and Washington. The adults are brown, about 13 to 17 mm long, and can be distinguished from other brown stink bugs by the presence of distinctive white bands on the antennae and their tendency to cluster together in groups.
The bug is a very serious pest that feeds on more than 100 different plant species and causes tens-of-millions of dollars of fruit losses annually in the United States.
