“…PH3 fumigation was found to only moderately induce superoxide dismutase (SOD), and to specifically inhibit the activity of catalase (CAT) in stored grain pests [20][21][22]. However, the regulation mechanism of CAT by PH3 is still unclear.…”

“…Consequently, inhibition of the electron transport chain (ETC) could lead to a raise of reactive oxygen species (ROS) production [3]. In addition, PH 3 can exacerbate oxidative stress through inhibition of catalase, peroxidase and increasing the superoxide dismutase (SOD) activity [9].…”

“…The combined information of these studies into phosphine resistance take on special evolutionary significance given that phosphine acts indirectly through mitochondrial disruption leading to elevated oxidative stress (Bolter and Chefurka, 1990;Chaudhry and Price, 1992;Chaudhry, 1997). Adaptation to oxidative stress and management of mitochondrial function are extremely important evolutionary processes, which remain to be fully investigated.…”

“…Because there are no suitable replacements for phosphine, it is important to understand the genetic factors that have contributed to resistance so that selection for even higher resistance levels can be avoided or delayed. Also, since phosphine appears to induce oxidative stress via the generation of oxyradicals (Bolter and Chefurka, 1990;Chaudhry and Price, 1992), the genes responsible for phosphine resistance may also be responsible for an adaptive defence response against oxidative stress.…”

Phosphine, a widely used fumigant for the protection of stored grain from insect pests, kills organisms indirectly by inducing oxidative stress. High levels of heritable resistance to phosphine in the insect pest of stored grain, Rhyzopertha dominica have been detected in Asia, Australia and South America. In order to understand the evolution of phosphine resistance and to isolate the responsible genes, we have undertaken genetic linkage analysis of fully sensitive (QRD14), moderately resistant (QRD369) and highly resistant (QRD569) strains of R. dominica collected in Australia. We previously determined that two loci, rph1 and rph2, confer high-level resistance on strain QRD569, which was collected in 1997. We have now confirmed that rph1 is responsible for the moderate resistance of strain QRD369, which was collected in 1990, and is shared with a highly resistant strain from the same geographical region, QRD569. In contrast, rph2 by itself confers only very weak resistance, either as a heterozygote or as a homozygote and was not discovered in the field until weak resistance (probably due to rph1) had become ubiquitous. Thus, high-level resistance against phosphine has evolved via stepwise acquisition of resistance alleles, first at rph1 and thereafter at rph2. The semi-dominance of rph2 together with the synergistic interaction between rph1 and rph2 would have led to rapid selection for homozygosity. A lack of visible fitness cost associated with alleles at either locus suggests that the resistance phenotype will persist in the field.
