Heliothine Trap Catches, July 17, 2025

Bollworm trap catches this week were similar to last week and about average for this time of year. Tobacco budworm trap catches were high in Leflore and Washington counties this week, so in these areas Heliothine egg densities are likely a mix of both species. All Bt crops are highly effective for controlling tobacco budworm, but many foliar insecticides, especially the older chemistries, are weak on tobacco budworm. Be aware of these differences between the species if trying to manage the Heliothine species.
