Cryptolestes ferrugineus is a serious pest of stored grain and has developed high levels of resistance to phosphine fumigants in many countries. Measuring differences in expression levels of certain ‘resistant’ genes by quantitative real-time PCR (qRT-PCR) may provide insights into molecular mechanisms underlying resistance to phosphine in C. ferrugineus, but reliable qRT-PCR results depend on suitable reference genes (RGs). We evaluated the stability of nine candidate RGs across different developmental stages and phosphine strains of C. ferrugineus, using four softwares. The results showed that RPS13 and EF1α were the most stable RGs, whereas α-TUB was the least under developmental stages. Across the different strains, RPS13 and γ-TUB were the most stable RGs, whereas CycA and GAPDH were the least. We confirmed the reliability of the selected RGs by qRT-PCR analyses of the mitochondrial cox1 gene. Expression of cox1 was not significantly different in the phosphine-resistant strain compared with the phosphine-susceptible strain, but three mitochondrial genes (nad3, atp6 and cob) were significantly down-regulated. These results suggest that alterations in the expressions of these three genes may be associated with phosphine resistance in C. ferrugineus. The findings will facilitate future functional genomics studies on the development and phosphine resistance in C. ferrugineus.

An understanding of insect movement and distribution within grain bulks is essential to effectively control insect pests. The aim of this review was to (1) identify the major and minor factors influencing the movement of adults of Cryptolestes ferrugineus and to (2) analyze their ability of resource detecting and cue orienting. Their response to major and minor environmental factors was related with the general features of the grain storage environment, their development requirement, and their ability of cue orienting and detecting. Their movement inside stored grain bins and in small-scale chambers was compared. Incompleteness of our current knowledge regarding their movement and cue detection under multi-factors is the main reason why we cannot predict yet their dispersal and distribution inside granaries accurately.
