Food consumption and utilization of food by Heliothis armigera (Hub.) (Lepidoptera; Noctuidae)
Eight plant species were tested for food consumption and utilization by last instar larvae of the cotton bollworm, Heliothis armigera (Hub.). Berseem (Trifolium alexandrinum L.) had the highest consumption (186.6-196.6 mg larva-1 day-1) and oat the lowest (12.6-16.4 mg larva-1 day-1). Maximum/minimum utilization for kale and bermuda grass were 90-95.9 and 63.9-75.6%, respectively. Considering both consumption and utilization, berseem was the most preferred food plant. Kale and apple were next in preference, with oat, wheat and bermuda grass the least preferred hosts.
