Heliothine Trap Counts, July 26, 2019

Both bollworm and tobacco budworm trap catches are average to above average this week. Bollworm moths are beginning to emerge from early corn fields, so strong moth flights are expected to continue for awhile since corn was planted over a large period of time this year. Most corn is no longer attractive to moths, so most oviposition is expected to be in cotton and soybean at this time. Tobacco budworm trap catches were not huge, but they were higher this week than any previous week this year, so expect that a portion of your heliothine eggs are tobacco budworm. The proportion in any particular field will be impacted by the local landscape and unfortunately we can’t predict these proportions at this time.
