Current Projects

 Brown Marmorated Stink Bug

Brown marmorated stink bug (BMSB), Halyomorpha halys, is an invasive species introduced to the USA from Asia in the mid-1990s.  BMSB is a severe agricultural and nuisance pest that feeds on over 170 host plants, including economically important fruit, vegetables, row crops, and ornamentals while also utilizing woodlands for host and overwintering habitat.  Since its introduction into the USA, BMSB has been detected in 43 states, with the most severe problems in the mid-Atlantic.  In 2010, $37 million in crop losses to apple occurred in this region and many other specialty and row crops including peaches, nectarines, tomatoes, peppers, sweet corn and soybeans incurred severe damage.

To better manage damaging BMSB populations in the mid-Atlantic, we are developing IPM tactics for BMSB in tree fruit including decision support tools and behaviorally based management tactics including border sprays and attract and kill.  We are assisting other countries in the development of surveillance programs.  We are tracking the spread and impact of the Asian parasitoid, Trissolcus japonicus, and we are learning more about BMSB dispersal throughout agroecosystems





Spotted Wing Drosophila

Spotted wing drosophila (SWD), Drosophila suzukii Matsumura, is an invasive, polyphagous fruit fly that attacks soft-skinned fruits including raspberries, blackberries, blueberries and cherries. Originally from Asia, SWD has successfully invaded the United States and the European and South American countries. At present, calendar-based insecticide applications are used to combat SWD.  

We have been developing an attract-and-kill system for SWD based on its visual ecology and foraging behavior. The system is known as attracticidal spheres and is being developed for both organic and conventional systems and for use in a variety of small fruit crops. This system has been used successfully against apple maggot fly, Rhagoletis pomonella, in apple orchards. Currently, we are evaluating attracticidal spheres in both raspberry and blueberry plantings with collaborators across the United States
