Control of the bollworm, Helicoverpa zea (Boddie), and tobacco budworm, Heliothis virescens (F.), required a higher percentage of the total cost than any other single pest in Mississippi. Mild winters for several consecutive years have been favorable for a statewide build up of boll weevils that have resulted in increased control costs. When observing all pests in all locations of the state it was apparent that the selection of some insecticides targeted on certain insects were not the material of choice.
