Amplification of a Cytochrome P450 Gene Is Associated with Resistance to Neonicotinoid Insecticides in the Aphid Myzus persicae
Puinean, Alin M.; Foster, Stephen P.; Oliphant, Linda; Denholm, Ian; Field, Linda M.; Millar, Neil S.; Williamson, Martin S.; Bass, Chris (2010-06)The aphid Myzus persicae is a globally significant crop pest that has evolved high levels of resistance to almost all classes of insecticide. To date, the neonicotinoids, an economically important class of insecticides ... -
Correlated responses to neonicotinoid insecticides in clones of the peach-potato aphid, Myzus persicae (Hemiptera: Aphididae)
Foster, Stephen P.; Cox, Diana; Oliphant, Linda; Mitchinson, Samantha; Denholm, Ian (2008-11)BACKGROUND: Although there are still no confirmed reports of strong resistance to neonicotinoid. insecticides in aphids, the peach-potato aphid (Myzus persicae Sulzer) shows variation in response, with some clones exhibiting ... -
English field samples of Thrips tabaci show strong and ubiquitous resistance to deltamethrin
Foster, Stephen P.; Gorman, Kevin; Denholm, Ian (2010-08)BACKGROUND: Onion thrips, Thrips tabaci Lindeman, is a prevalent pest of glasshouse and field vegetables, such as leeks and salad onions. Pesticides are the main option for control, but this approach risks the evolution ... -
Fitness trade-off in peach-potato aphids (Myzus persicae) between insecticide resistance and vulnerability to parasitoid attack at several spatial scales
Foster, Stephen P.; Denholm, Ian; Poppy, G. M.; Thompson, R.; Powell, W. (2011-12)Insecticide-resistant clones of the peach-potato aphid, Myzus persicae (Sulzer), have previously been shown to have a reduced response to aphid alarm pheromone compared to susceptible ones. The resulting vulnerability of ... -
Inheritance of L1014F and M918T sodium channel mutations associated with pyrethroid resistance in Myzus persicae
Eleftherianos, Ioannis; Foster, Stephen P.; Williamson, Martin S.; Denholm, Ian (2008-10-23)Two amino acid substitutions (L1014F and M918T) in the voltage-gated sodium channel confer target-site resistance to pyrethroid insecticides in the peach potato aphid, Myzus persicae. Pyrethroid-resistant and -susceptible ... -
Mutation of a nicotinic acetylcholine receptor beta subunit is associated with resistance to neonicotinoid insecticides in the aphid Myzus persicae
Bass, Chris; Puinean, Alin M.; Andrews, Melanie; Cutler, Penny; Daniels, Miriam; Elias, Jan; Paul, Verity Laura; Crossthwaite, Andrew J.; Denholm, Ian; Field, Linda M.; Foster, Stephen P.; Lind, Rob; Williamson, Martin S.; Slater, Russell (2011-05-31)Background: Myzus persicae is a globally important aphid pest with a history of developing resistance to insecticides. Unusually, neonicotinoids have remained highly effective as control agents despite nearly two decades ... -
Susceptibility of standard clones and European field populations of the green peach aphid, Myzus persicae, and the cotton aphid, Aphis gossypii (Hemiptera: Aphididae), to the novel anthranilic diamide insecticide cyantraniliprole
Foster, Stephen P.; Denholm, Ian; Rison, Jean-Luc; Portillo, Hector E.; Margaritopoulis, John; Slatere, Russell (2012-04)BACKGROUND: Parthenogenetic clones of the green peach aphid, Myzus persicae (Sulzer), and the cotton aphid, Aphis gossypii Glover, were tested with the anthranilic diamide insecticide cyantraniliprole (i.e. DuPont (TM) ...
