“…The mortality observed in non-hermetic storage may be related to the age of the insects used in this experiment, which may have died in a natural way when completing their life cycle; the longevity of this species is approximately 140.5 days for females and 142 days for males (Sousa et al, 2009).…”

“…Pimentel et al (2007) found that reproduction and respiration rates were negatively correlated with resistance ratio across a range of field samples of T. castaneum. Sousa et al (2009) reported a tendency for slower development in more resistant samples, when a range of T. castaneum samples were compared. These studies provide strong evidence for fitness costs associated with phosphine resistance, but they used unselected field samples which may have contained multiple genotypes.…”

“…Therefore, knowing if there are fitness costs associated with phosphine resistance could help in resistance management. Fitness has been investigated in a range of insect pests of stored grain using different experimental approaches (Pimentel et al, 2007;Schlipalius et al, 2008;Sousa et al, 2009;Pimentel et al, 2011;Jagadeesan et al, 2012Jagadeesan et al, , 2013Daglish et al, 2014). Some studies have used the population cage approach in which susceptible and resistant strains are hybridized and the resulting populations are reared in the absence of phosphine selection.…”

“…(Coleoptera: Curculionidae) is a major corn pest and its by products are found in virtually all storage and processing facilities of Brazil (Aguiar et al, 2010;Conceição et al, 2012). This insect is controlled by pyrethroid and organophosphate insecticides (Guedes et al, 2008) and phosphine fumigant (Sousa et al, 2009). However, in view of the high levels of resistance to these insecticides, the incorporation of new forms of control to handle pest insects in the storage sector is important (Freitas et al, 2011).…”
