Journal ArticleDOI
Identification of mutations conferring insecticide-insensitive AChE in the cotton-melon aphid, Aphis gossypii Glover.
TL;DR: Two mutations in the ace1 gene of Aphis gossypii are associated with insensitivity of acetylcholinesterase (AChE) to carbamate and organophosphate insecticides, providing a molecular explanation of why pirimicarb has a specific aphicidal action.
Journal ArticleDOI
A comparative study of voltage-gated sodium channels in the Insecta: implications for pyrethroid resistance in Anopheline and other Neopteran species.
TL;DR: Isolation of the sodium channel cDNA for An.
Journal ArticleDOI
Analogous pleiotropic effects of insecticide resistance genotypes in peach–potato aphids and houseflies
TL;DR: It is shown that single-point mutations conferring target-site resistance to pyrethroids and DDT in aphids and houseflies, and gene amplification conferring metabolic resistance to organophosphates and carbamates in Aphids, can have deleterious pleiotropic effects on fitness.
Journal ArticleDOI
Ryanodine receptor point mutations confer diamide insecticide resistance in tomato leafminer, Tuta absoluta (Lepidoptera: Gelechiidae).
Emmanouil Roditakis,Denise Steinbach,Gerald Moritz,Emmanouil Vasakis,Marianna Stavrakaki,Aris Ilias,Lidia García-Vidal,María del Rosario Martínez-Aguirre,Pablo Bielza,Evangelia Morou,Jefferson E. Silva,Wellington M. Silva,Ηerbert A.A. Siqueira,Sofia Iqbal,Bartlomiej J. Troczka,Martin S. Williamson,Chris Bass,Anastasia Tsagkarakou,John Vontas,Ralf Nauen +19 more
TL;DR: The discovery of diamide resistance mutations in T. absoluta populations of diverse geographic origin has serious implications for the efficacy of diamides under applied conditions, and the implementation of appropriate resistance management strategies is strongly advised to delay the further spread of resistance.
Journal ArticleDOI
Mutations in DIIS5 and the DIIS4–S5 linker of Drosophila melanogaster sodium channel define binding domains for pyrethroids and DDT
P.N.R. Usherwood,Thomas G. Davies,Ian R. Mellor,Andrias O. O'Reilly,F. Peng,Horia Vais,Bhupinder P. S. Khambay,Linda M. Field,Martin S. Williamson +8 more
TL;DR: DDT potency was unaffected by M918T, but abolished by T929I and reduced by L925I, L932F and I936V, suggesting that DIIS5 contains at least part of the DDT binding domain, and the data support a computer model of pyrethroid andDDT binding.
