The order of tolerance Loan atmosphere of less than 1% O2 (27°C and 50% RH) produced by an exothermic inert atmosphere generator was: the Angoumois grain moth, Sitotroga cerealella (Olivier)—larvae-pupae > eggs > adults; the almond moth, Cadra cautella (Walker) — eggs > pupae > larvae > adults; and the Indian meal moth, Plodia interpunctella (Hübner) — pupae> eggs > adults > larvae. All stages of the Indian meal moth and all except the eggs of the almond moth were killed by 24-h exposures: eggs of the almond moth required a 48-h exposure. The tolerance of Angoumois grain moth larvae to the inert atmosphere increased with each successive week of growth after the eggs hatched and the larvae entered the wheat kernels. An exposure of 120 h was required to cause 100% mortality of fully grown larvae and pupae.
