“…The hypersusceptibility of adult to plant powders when compared with susceptibility of the larvae indicates that larvae were tolerant to the introduced plants powders. Williams et al (1980) found when using nitrogen atmosphere that the duration of exposure required to kill the larvae of T. granarium was five days. Even when Pirimiphos-methyl was used at the recommended dose, at 5 DAT there was a significantly lower percentage of larval mortality compared with mortality in the mixture of two plant species.…”

Laboratory studies were carried out to investigate bioactivity of Piper guineense seeds and Moringa oleifera leaf powders applied singly or in a mixture against larvae and adult Trogoderma granarium Everts in airtight containers. Three levels (0.0 g, 0.5 g, and 1.0 g/20 g groundnut seeds) of the plant powders were used and pirimiphos-methyl was applied at 0.01 g/20 g seeds (recommended dose). Another control consisting of untreated seeds with aerated lids was included in the bioassay. Both larvae and adults were not killed in control with aerated lids throughout the experimental period and larvae were also tolerant to airtight storage conditions. Adults were more susceptible to plant powders than larvae and adult mortality recorded in P. guineense at 1.0 g, 0.5 g and M. oleifera at 1.0 g/20 g seeds were not significantly different from the mortality observed with the recommended dose of Pirimiphos methyl at five days after treatment (DAT). Larval mortality observed in a mixture of both plants (1:1; w/w) caused significantly higher mortality (77.5%) than other treatments at 5 DAT. All treatments (P. guineense and M. oleifera applied singly or in a mixture) were repellant to larvae T. granarium with 60% repellency recorded in the mixture of plants, 50% repellency in P. guineense and 30% repellency in M. oleifera slurry. The water absorption capacity of treated seeds was not affected by treatment with plant powders and ranged from 31.98% to 37.59%.

“…Earlier studies have shown that T. granarium is a particularly tolerant species to extreme conditions, such as both heat and cold [52][53][54]. The relatively reduced susceptibility of T. granarium to low oxygen [27,52,55] should be considered when drawing modified/controlled atmosphere-based protocols for pre-shipment and quarantine treatments.…”

“…In contrast to other fumigants, eggs are not always the most tolerant life stage. For instance, William et al [55] found that with the maize weevil, Sitophilus zeamais Motchulsky, (Coleoptera: Curculionidae), eggs and adults were more susceptible than pupae. Moreover, Athanassiou et al [17] found complete control at 38-43 • C of eggs, pupae, and adults of T. confusum and some survival was recorded for larvae.…”

Nitrogen treatment can be used as an alternative method to chemical control. Most of the research on nitrogen treatment mainly investigated the optimum concentration of oxygen level as well as duration as a means of insect control. Other parameters such as temperature and different insect species have been extensively studied and recent research focus on the modelling of nitrogen concentration and the efficacy on commodity. In this paper, we briefly review the major parameters (temperature, oxygen level, relative humidity, exposure time) using nitrogen treatment against stored product insects. Exposure to different oxygen levels or different exposure times can remarkably change pest control mortality. Moreover, different insect species and life stages have differing susceptibility to nitrogen treatment. Finally, these studies are reviewed in this paper to illustrate that nitrogen treatment can be used as a part of an IPM strategy.

“…Oxygen consumption under normal conditions is about 0.04 µmol h −1 mg −1 (of living weight) for Tribolium castaneum (Herbst, 1797) and Tenebrio molitor (Linnaeus, 1758), and as low as 0.005 and 0.006 for Cryptoglossa muricata (LeConte, 1851) and Eleodes longicollis (LeConte, 1851), respectively [24]. Eggs and adults of S. zeamais are more susceptible to anoxia than larvae and pupae [25]. Atmospheric pressure is relevant for insects' breathing.…”

Warehouse pests cause losses in seed quality by physically damaging seeds, carrying other pathogens, and leaving residues of their consumption or their remains. Taking into account that warehouse pests have higher metabolism rates than seeds, in the present study, the viability of Sitophilus zeamais (Motschulsky & V.de, 1855) insects and the germination of corn seeds were evaluated for 93 and 180 days, respectively, under conditions of a partial vacuum (0.26 atm (atmosphere)), hermetic sealing, and air exchange. The partial vacuum environment (0.26 atm) did not negatively affect the germination of the seeds over a period of 180 days and resulted in the mortality of adult insects from the 4th day onwards; it also completely prevented physical damage to the seeds. The hermetic packaging did not negatively affect germination, but the insects remained active until day 34, and there was severe damage to the seeds used for their sustenance. Similarly, the gas exchange packaging did not affect germination, but the insects remained active until the last day of observation (93) and also caused severe damage to the seeds used for their maintenance. Partial vacuum (0.26 atm) storage represents a practical solution in certain conditions, for example, the short-term (6 months) storage of germplasms at room temperature (24–26 °C); it can also be useful in the storage and transfer of grains, with the possibility of eliminating or reducing the need for insecticide applications.
