Species composition of Heliothinae captured in cone traps baited with synthetic bollworm or tobacco budworm pheromones

The species composition of the Heliothinae captured in cone traps baited with synthetic pheromones of the bollworm, Helicoverpa zea (Boddie), or tobacco budworm, Heliothis virescens (F.), was determined in Louisiana in 1992. Only tobacco budworms comprised the 49,729 specimens from traps baited with tobacco budworm lure. The 25,819 specimens collected in traps baited with bollworm lure included one Heliothis phloxiphaga Grote and Robinson, 10 specimens that may be hybrids between the bollworm and H. phloxiphaga, and 15 tobacco budworms. These small numbers of other Heliothinae, however, would not affect the interpretation of pheromone trap catches of these species or insecticide resistance monitoring data.
