TL;DR: Results from insecticide bioassays with synergists suggested a major involvement of esterase as the cypermethrin resistance mechanism, while no clear result was obtained for chlorpyrifos-methyl, which provides support for target site resistance to pyrethroids in the DDT and pyrethroid resistant population used in this study.

TL;DR: This investigation aims to verify whether differences in respiration rate and fat body morphology are related to differences in rate of development in Brazilian populations of S. zeamais resistant to insecticides, and thereby provide evidence for the existence (or not) of a physiological fitness cost acting against insecticide resistance in maize weevils.

TL;DR: The V410L mutation drastically reduced the sensitivity of mosquito sodium channels expressed in Xenopus oocytes to both type I and type II pyrethroids and presents a serious challenge for the control of A. aegypti in Brazil.

TL;DR: Current knowledge about the molecular mechanisms of action of pyrethroids and SCBIs are summarized, and the differences in the molecular interaction of these insecticides with insect versus mammalian sodium channels are highlighted.

TL;DR: The risks associated with biorational compounds need to be revisited and the outcomes of such inquiry could be decisive for their future use in pest management programs.
