Brown marmorated stink bug distribution update for August 6, 2015
Our scouts found a BMSB nymph in Franklin County soybean this past week. Populations in soybean remain low; please also see the black light trap report. Here is the map of all 3 counties where BMSB have been detected in soybean in 2015: BMSB_map_6_Aug
Kudzu bug distribution update for August 6, 2015
Kudzu bug has been found in soybean in 30 Virginia counties. Most populations were low (zero to 2 adults per 15 sweeps), although a field in Pittsylvania at R2 growth stage had an average of 13 kudzu bugs per sample. Please see the data table for recent samples (kb_data_6_Aug) and the state distribution map (KB_map_6_Aug) for more details.

Kudzu bug distribution update for July 16, 2015
Our scouts (Ed Seymore, Jamie Hogue, and Dr. Herbert’s Entomology team) have started sampling soybean fields across Virginia for kudzu bug and brown marmorated stink bug. The file attached at the end of this paragraph indicates the counties where kudzu bug has been found (blue counties = kudzu bug found in soybean; maroon counties = kudzu bug found on other hosts such as kudzu). Please note that we have not yet sampled all counties on our survey route. I will continue to provide weekly updates on this, including pest population levels, as the season progresses. KB_7_16_2015
