Corn earworm/bollworm (Helicoverpa zea) resistance monitoring:  The number of moths surviving the 24-hour exposure to 5 micrograms of cypermethrin in this week’s vial tests was 45.8% (n = 180 moths evaluated).  The seasonal average is 43.4% survival, based on 1,255 moths tested. Black light trap counts:  Corn earworm moth captures dropped slightly from the previous weeks’ counts; brown marmorated stink bug counts were zero across all reporting stations.  Please see the attached tables (pdf document) for more details:  BLT_8_Sep_2016
