Abstract
Time elapsed for Pectinophora gossypiella (Saunders) larvae to dia after exposed to pyemotes herfsi (oudemans) varied according to number of parasitic mite individuals and cotton bollworm larval instar. Death of larvae took place after 24 hours of infestation in the 1st instar larva exposed to 1.5 or 10 parasitic mites. Also, 2nd and 4th instars exposed to 5 and one parasitoid, respectively. The duration before death of insect larva increased as larva de‌veloped. when the 2nd instar larva was individually exposed to one or ten parasitic mites the duration of death averaged 1.7 and 1.3 days, re‌spectively. The duration before death averaged 3.2,4.3 and 3.0 days when one, five or ten parasitic mites, respectively were introduced to the 3rd instar insect larva. This duration averaged 5.2 and 4.8 days when five or ten mites, respectively were introduced to a 4th instar larva.
