BMSB and kudzu bug in soybean: update for Aug. 25, 2016

This past week our scouts found four new Virginia counties with brown marmorated stink bug (BMSB) in soybean (Caroline, Shenandoah, Rockbridge, and Henry).  Thresholds for field edges where BMSB is the predominant stink bug species are 3-5 adults + medium and large nymphs per 2-minute visual count, or 3-5 in 15 sweeps.  The Shenandoah field (R5 growth stage) that was sampled was above threshold with 8 BMSB per 2-minute count; six counties were approaching threshold (please see the map for specifics).

Kudzu bugs were found in three new counties (Prince George [reported by ANR Agent Scott Reiter), James City, and Franklin).  No counties had threshold levels of kudzu bugs (threshold is one nymph per sweep, which equals 15 nymphs per 15 sweeps).
