Abstract
Infestation of pink bollworm, which is generally considered monophagous continue to grow and spread. This study was conducted to record pink bollworm infestation on four host plants under field and laboratory conditions. Lucerne and tomato were free from pink bollworm damage while okra fruit and cotton flowers and bolls were highly infested. Pink bollworm showed strong affinity with cotton flowers with rosettes first appearing on 15th June and peaking at the end of season. Boll infestation started on 15th July and peaked on 15th October. In okra fruit, first infestation appeared on 30th August and peaked on 30th October. Pink bollworm individuals took 52.698 days to complete their life cycle when reared on okra and 54.775 days on cotton. The morphometric measurement of reared pink bollworm was also calculated.
