First to fifth instar larvae of Corcyra cephalonica were fumigated with CO2 for durations of 10, 20, 30 and 45 min. Fifth instar larvae which received a first dose of fumigation for 30 min, were given an additional, second dose of fumigation for varying durations, at 60, 120 and 180 min interval after the first fumigation. Fumigated first instar larvae blacked out quickly and revived slowly compared to the older instars. Upon revival, the fourth and fifth instar larvae spun silken cocoons faster than the first instar. There were significant changes in the tissue protein profile of the larvae exposed to the two different fumigation schedules. [copyright] 2004 Association for Advancement of Entomology
