“…Additionally, according to Finkelman et al (2006) when T. granarium, L. serricorne, and O. surinamensis were subjected to 50 mmHg at 30°C, the egg was again the most tolerant stage in all three species, the times needed to obtain 99 % mortality being 46, 91, and 32 h, respectively ( Table 2). Adults of T. granarium and L. serricorne, and pupae of O. surinamensis were the most susceptible.…”

“…Adults of T. granarium and L. serricorne, and pupae of O. surinamensis were the most susceptible. Mbata and Phillips (2001) tested eggs, larvae, and pupae of T. castaneum, P. interpunctella, and R. dominica Table 2 The time in hours needed to obtain mortality of the most resistant stage (egg) of six storage insects as expressed in LT values at a low pressure of 50 mmHg, 30°C, and 55 ± 3 % r.h. (Finkelman et al 2006 exposed to 32.5 mmHg in glass chambers at 25, 33, 37, and 40°C for times ranging from 30 min to 144 h. Pupae of T. castaneum and R. dominica were more tolerant to low pressure than larvae. In all life stages, mortality increased with increasing exposure time to low pressure and also with increasing temperature.…”

Storage insects are aerobic organisms requiring oxygen for their survival. Therefore, they respond to altered atmospheric gas compositions containing low O 2 or high CO 2 . The lower the grain moisture content (m.c.) and the corresponding intergranular humidity, the higher the mortality-due to the desiccation effect on insects caused by low O 2 or elevated CO 2 concentrations. To achieve insect control, the temperature of the grain should be above 21°C. Hermetic storage is based on the principle of generation of an oxygen-depleted, carbon dioxide-enriched interstitial atmosphere caused by the respiration of the living organisms in the ecological system of a sealed storage. A sufficiently low oxygen and elevated CO 2 atmosphere is created through a natural metabolic process based on insect respiration and, in cases where the commodity has sufficiently high moisture, the respiration of the microorganisms within a sealed storage system. An O 2 ingress rate of 0.05 %/day is sufficient to arrest the theoretical weight loss at a level of 0.018 % over 1-year storage period. At this ingress rate, the possibility of a residual surviving insect population is eliminated. This low O 2 ingress level could serve as a guideline for the sealing specifications of structures appropriate to the hermetic storage method. The applications for which hermetic technology has been most widely accepted are (a) for longterm storage of cereal grains, primarily rice, corn, barley, and wheat; (b) for long-term storage of a variety of seeds to preserve germination potential and vigor, and (c) for quality preservation of high-value commodities, such as dried fruits.

“…Considerable research has been conducted on cosmopolitan pests such as Tribolium castaneum, Tribolium confusum, Sitophilus zeamais, Sitophilus oryzae, Rhyzopertha dominica, Cryptolestes ferrugineus and Oryzaephilus surinamensis (Carli et al, 2010;Chiappini et al, 2009;Finkelman et al, 2006;Lord, 2009;Riudavets et al, 2009). Generally, a reduction in the O 2 content to 3% or lower or an increase in CO 2 content to 60% or higher is effective for control of most storage pests (Navarro, 2006).…”
