Abstract:Survival of live insects accidentally packaged with military rations in vacuumized and unvacuumized airtight flexible food pouches was determined for adults and larvae of Cadra cautella (Walker), Lasioderma serricorne (F.), Tribolium castaneum (Herbst), and Trogoderma variabile Ballion. Seven foods and four types of pouches were tested; each food was packaged in a specific type of pouch. Some C. cautella and T. castaneum were found alive in various unvacuumized pouches after 3 weeks of confinement. Most were dead after 6 weeks. T. variabile and L. serricorne survived in some pouches for the duration of the tests (12 weeks). L. serricorne penetrated some of the pouches and escaped. Only L. serricorne survived for 1 week in pouches vacuum-sealed with a vacuum of 48.8 mm Hg; all were dead at 3 weeks. Some pouches with a minimal vacuum (533.0 mm Hg) allowed survival of T. variabile and L. serricorne for 12 weeks. Progeny from adults or insects from tests started with larvae were usually smaller and less developed than those in the controls that had an unlimited supply of air.
