BMSB and kudzu bug update for Aug. 9, 2016

Our soybean scouts found brown marmorated stink bug (BMSB) in soybean in nine more Virginia counties last week (Goochland, Fluvanna, Albemarle, Buckingham, Greene, Cumberland, Nelson, Bedford, and Franklin).  The Bedford soybean field was in the R4 growth stage, and was above threshold with 8 BMSB observed in a 2-minute visual count (the threshold is 3-5).  More scouting, management, and other information can be found in the publication, “Brown Marmorated Stink Bug Biology and Management in Mid-Atlantic Soybeans.”  Nelson county was just reaching threshold with 3 BMSB in a 2-minute visual count; all other “positive” counties had relatively low numbers of BMSB reported.  Here is the map for the season:


Kudzu bugs were detected in nine new Virginia counties last week (Fluvanna, Albemarle, Cumberland, Powhatan, Nottoway, Louisa, Greene, Amherst, and Henry).  None of them were near the threshold of 1 kudzu bug nymph per sweep.  The kudzu bug map:
