Age-specific expression of a P450 monooxygenase (CYP6CM1) correlates with neonicotinoid resistance in Bemisia tabaci
Jones, Christopher M.; Daniels, Miriam; Andrews, Melanie; Slater, Russell; Lind, Robert J.; Gorman, Kevin; Williamson, Martin S.; Denholm, Ian (2011-11)The whitefly, Bemisia tabaci (Hemiptera: Aleyrodidae), is an invasive insect pest of agriculture and horticulture worldwide. The neonicotinoid insecticides, which target nicotinic acetylcholine receptors in post-synaptic ... -
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 ... -
Characterisation of imidacloprid resistance mechanisms in the brown planthopper, Nilaparvata lugens Stal (Hemiptera: Delphacidae)
Puinean, Alin M.; Denholm, Ian; Millar, Neil S.; Nauen, Ralf; Williamson, Martin S. (2010-06)Effective control of the brown planthopper, Nilaparvata lugens Stal, across rice-growing regions of Asia has been seriously compromised over the last 2 years by the appearance of widespread resistance to the neonicotinoid ... -
Global patterns in genomic diversity underpinning the evolution of insecticide resistance in the aphid crop pest Myzus persicae
Singh, Kumar Saurabh; Cordeiro, Erick M. G.; Troczka, Bartlomiej J.; Pym, Adam; Mackisack, Joanna; Mathers, Thomas C.; Duarte, Ana; Legeai, Fabrice; Robin, Stéphanie; Bielza, Pablo; Burrack, Hannah J.; Charaabi, Kamel; Denholm, Ian; Figueroa, Christian C.; ffrench-Constant, Richard H.; Jander, Georg; Margaritopoulos, John T.; Mazzoni, Emanuele; Nauen, Ralf; Ramírez, Claudio C.; Ren, Guangwei; Stepanyan, Ilona; Umina, Paul A.; Voronova, Nina V.; Vontas, John; Williamson, Martin S.; Wilson, Alex C. C.; Xi-Wu, Gao; Youn, Young-Nam; Zimmer, Christoph T.; Simon, Jean-Christophe; Hayward, Alex; Bass, Chris (2021-07-07)Abstract: The aphid Myzus persicae is a destructive agricultural pest that displays an exceptional ability to develop resistance to both natural and synthetic insecticides. To investigate the evolution of resistance in ... -
High-throughput allelic discrimination of B and Q biotypes of the whitefly, Bemisia tabaci, using TaqMan allele-selective PCR
Jones, Christopher M.; Gorman, Kevin; Denholm, Ian; Williamson, Martin S. (2008-01)BACKGROUND: B and Q biotypes of the whitefly, Bemisia tabaci (Gennadius), are generally regarded as the most significant given their global distribution and strong resistance to insecticides. Since these biotypes can coexist ... -
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 ... -
Mutations in the sodium channel associated with pyrethroid resistance in the greenhouse whitefly, Trialeurodes vaporariorum
Karatolos, Nikos; Gorman, Kevin; Williamson, Martin S.; Denholm, Ian (2012-06)BACKGROUND: Trialeurodes vaporariorum Westwood is an important pest of protected crops in temperate regions of the world. Resistance to pyrethroid insecticides is long established in this species, but the molecular basis ... -
New methods for the detection of insecticide resistant Myzus persicae in the UK suction trap network
Anstead, James A.; Williamson, Martin S.; Denholm, Ian (2008-07-10)1 Myzus persicae is a highly polyphagous pest of U.K. agriculture. It presents particular control difficulties because it has developed resistance to several insecticide classes. 2 For almost 20 years, M. persicae collected ... -
Over-Expression of a Cytochrome P450 Is Associated with Resistance to Pyriproxyfen in the Greenhouse Whitefly Trialeurodes vaporariorum
Karatolos, Nikos; Williamson, Martin S.; Denholm, Ian; Gorman, Kevin; Ffrench-Constant, Richard H.; Bass, Chris (2012-02-08)Background: The juvenile hormone mimic, pyriproxyfen is a suppressor of insect embryogenesis and development, and is effective at controlling pests such as the greenhouse whitefly Trialeurodes vaporariorum (Westwood) which ... -
Pyrosequencing the transcriptome of the greenhouse whitefly, Trialeurodes vaporariorum reveals multiple transcripts encoding insecticide targets and detoxifying enzymes
Karatolos, Nikos; Pauchet, Yannick; Wilkinson, Paul; Chauhan, Ritika; Denholm, Ian; Gorman, Kevin; Nelson, David R.; Bass, Chris; Ffrench-Constant, Richard H.; Williamson, Martin S. (2011-01-24)Background: The whitefly Trialeurodes vaporariorum is an economically important crop pest in temperate regions that has developed resistance to most classes of insecticides. However, the molecular mechanisms underlying ... -
