Journal ArticleDOI
The evolution of insecticide resistance in the peach–potato aphid, Myzus persicae
Chris Bass,Alin M. Puinean,Christoph T. Zimmer,Ian Denholm,Linda M. Field,Stephen P. Foster,Oliver Gutbrod,Ralf Nauen,Russell Slater,Martin S. Williamson +9 more
TL;DR: The peach potato aphid, Myzus persicae, is a globally distributed crop pest with a host range of over 400 species including many economically important crop plants as discussed by the authors.
Journal ArticleDOI
Amplification of a cytochrome P450 gene is associated with resistance to neonicotinoid insecticides in the aphid Myzus persicae.
Alin M. Puinean,Stephen P. Foster,L. Oliphant,Ian Denholm,Linda M. Field,Neil S. Millar,Martin S. Williamson,Chris Bass +7 more
TL;DR: The mechanisms underlying resistance to the neonicotinoid insecticides were investigated using biological, biochemical, and genomic approaches and it was suggested that P450-mediated detoxification plays a primary role in resistance, although additional mechanism(s) may also contribute.
Journal ArticleDOI
Mutation of a nicotinic acetylcholine receptor β subunit is associated with resistance to neonicotinoid insecticides in the aphid Myzus persicae
Chris Bass,Alin M. Puinean,Melanie Andrews,Penny Cutler,Miriam Daniels,Jan Elias,Verity Laura Paul,Andrew J. Crossthwaite,Ian Denholm,Linda M. Field,Stephen P. Foster,Rob Lind,Martin S. Williamson,Russell Slater +13 more
TL;DR: This study finds a single point mutation in the loop D region of the nAChR β1 subunit of the resistant clone of M. persicae, causing an arginine to threonine substitution (R81T) and provides further validation of exisiting models of neonicotinoid binding and selectivity for insect nA ChRs.
Journal ArticleDOI
A sodium channel point mutation is associated with resistance to DDT and pyrethroid insecticides in the peach-potato aphid, Myzus persicae (Sulzer) (Hemiptera: Aphididae).
David Martínez-Torres,Stephen P. Foster,Linda M. Field,Alan L. Devonshire,Martin S. Williamson +4 more
TL;DR: These findings, and the linkage disequilibrium of the kdr mutation within clones overproducing the E4 esterase, have important implications for the evolution of resistance in this insect and for the use of pyrethroid sprays in the management of M. persicae populations in the field.
Journal ArticleDOI
The ups and downs of insecticide resistance in peach-potato aphids (Myzus persicae) in the UK
TL;DR: The peach-potato aphid, Myzus persicae, provides an excellent demonstration of how genetic and ecological factors can interact to determine the dynamics of resistance and influence success of resistance management.
