We are seeing quite a bit of variation in species makeup from field to field at this time. Scouts should be observant for moth activity when scouting. Moths are most active after sunset but some can be seen during the day while walking fields. TBW and CEW moths can be easily recognized. Each forewing has three slanted, dark bands.
CEW moths are yellowisholive in color with a dark spot on the forewing.
Bollgard cotton has provided excellent control of TBW, but some treatments for CEW have been needed. Control of large TBW is very difficult. If pyrethroid resistance is a concern, non-pyrethroid chemistry should be used. As corn continues to dry down and be shelled, we may expect to see an increase in stink bug numbers and damage. Several county agents and consultants have made observations of higher stink bug numbers on the edge of fields which border peanuts.
