Soybean–brown marmorated stink bug (BMSB): Our scouts detected BMSB in two new counties this week–Charles City and Stafford. Eight counties were at threshold (3-5 per 2-minute visual count along the field edge)–these are listed at the bottom of the map.
Soybean–kudzu bug: A range of zero to 5 kudzu bugs per 15 sweeps was reported this week. While no counties were at threshold levels (15 kudzu bugs per 15 sweeps), the highest numbers were reported in Campbell (5), Appomattox (4), and Amelia (3 per 15 sweeps).
Sorghum–white sugarcane aphid, Melanaphis sacchari: No new counties reported for this pest this week. So far this season, it has been confirmed in the following Virginia counties: Amelia, Bedford, Charles City, Dinwiddie, Franklin, Greensville, Hanover, Isle of Wight, New Kent, Nottoway, Prince George, Southampton, Suffolk, Surry, and Sussex.
Corn earworm/bollworm resistance monitoring: Survival of moths in the vial tests remains high. We evaluated 297 moths this week, with 40.5% survival to the 5 microgram/vial rate of cypermethrin. Our seasonal average stands at 42.8% survival (n = 1,552 moths evaluated).
Black light trap report: Some reporting stations had a small bump upwards in the number of corn earworm moths captured (Warsaw, Prince George, Essex); declines occurred in Suffolk and Southampton. Very few BMSB were caught. Please refer to the tables for more information. BLT_15_Sep_2016
