Abstract:Various stages of Callosobruchus maculatus (F.) were exposed to a modified atmosphere (O2 < 1%, CO2 = 9–9.5%, balance principally N2) produced by an exothermic inert atmosphere generator. The order of tolerance to the low O2 atmosphere was 21-day-old larvae = pupae > 14-day-old larvae > 7-day-old larvae > 1-day-old eggs > 3 day-old-eggs > adults. At 27°C, times of exposure for 100% mortality were 48 h for adults, 96 h for 1- and 3-day-old eggs, 120 h for 7- and 14-day-old larvae, and 192 h for 21-day-old larvae and pupae.
