Abstract:Artificial infestations (1 larva/plant) of wild Heliothis virescens (F.) caused economic yield losses to 2 varieties (Coker 411 and NC 2326) of flue-cured tobacco. Different infestation levels influenced quantitative tobacco losses, but no qualitative differences were apparent. Maximum yield reductions occurred at 20 and 50% infestation levels instead of the expected 100% level with both varieties. The maximum yield loss per larva occurred at the 10 and 20% infestation levels. Larval distribution, possible larval interference, and natural enemies (especially parasitism) were believed to have affected the degree of foliage loss at the various infestation levels.
