Insecticide Resistance
Devine, G; Denholm, Ian (Academic Press, 2003) -
Insecticide resistance and biotype status of populations of the tobacco whitefly Bemisia tabaci (Hemiptera : Aleyrodidae) from Turkey
Erdogan, Cem; Moores, Graham D.; Gurkan, M. Oktay; Gorman, Kevin J.; Denholm, Ian (2008)Analysis using polyacrylamide gel electrophoresis (PAGE) of four strains of the tobacco whitefly, Bemisia tabaci, collected from cotton in Turkey showed all insects to be assignable to the geographically widespread B biotype ... -
Insecticide resistance in Bemisia tabaci biotype Q (Hemiptera: Aleyrodidae) from China
Luo, C.; Jones, C. M.; Devine, G.; Zhang, F.; Denholm, Ian; Gorman, Kevin (2010-05)Dispersion of invasive biotypes of the tobacco whitefly, Bemisia tabaci, has led to protracted crop protection constraints in numerous countries over recent decades. These polyphagous, highly efficient vectors of plant ... -
Insecticide resistance: from science to practice.
Williamson, MS; Anstead, James A.; Devine, GJ; Devonshire, AL; Field, LM; Foster, SP; Moores, Graham D.; Denholm, Ian (British Crop Protection Council (BCPC), 2003-11-10) -
Interactions between transgenic plants, the diamondback moth and natural enemies
Schuler, T H; Potting, RPJ; Denholm, Ian; Poppy, GM (The Regional Institute Ltd, NSW, Australia, 2001-11-26) -
Intrinsic and extrinsic factors influencing large African herbivore movements
Venter, Jan A.; Prins, Herbert H.T.; Mashanova, Alla; de Boer, Willem F.; Slotow, Rob (2015-11-01)Understanding environmental as well as anthropogenic factors that influence large herbivore ecological patterns and processes should underpin their conservation and management. We assessed the influence of intrinsic, ... -
Investigating the vulnerability of a keystone African savanna tree to fire and herbivory
Helm, Chantal (2013) -
Keys to the case bearing caddis larvae of Britain and Ireland
Edmonds-Brown, Veronica (2004-03) -
Large-scale monitoring of imidacloprid susceptibility in the cat flea, Ctenocephalides felis
Rust, M. K.; Denholm, Ian; Dryden, M. W.; Payne, P.; Blagburn, B. L.; Jacobs, D. E.; Bond, R.; Mencke, N.; Schroeder, I.; Weston, S.; Vaughn, M.; Coleman, G.; Kopp, S. (2011-03)Although on-animal topical treatment with compounds such as imidacloprid has revolutionized the control of the cat flea, Ctenocephalides felis (Bouche) (Siphonaptera: Pulicidae), the development of insecticide resistance ... -
Management insecticide resistance in whiteflies and aphids in cotton fields
Horowitz, A. R.; Denholm, Ian; Nichols, R L (USDA-ARS, 2007) -
A mechanism-based approach to monitoring for insecticide resistance in the peach-potato aphid, Myzus persicae
Williamson, MS; Andrews, M C; Anstead, James A.; Field, LM; Moores, Graham D.; Foster, SJ; Devonshire, AL; Denholm, Ian (Society of Chemical Industry, 2004) -
Molecular and morphological phylogenetics of the digitate-tubered clade within subtribe Orchidinae s.s. (Orchidaceae: Orchideae)
Bateman, Richard; Murphy, Alexander; Hollingsworth, Peter; Hart, Michele; Denholm, Ian; Rudall, Paula (2018-11-17)The digitate-tubered clade (Dactylorhiza s.l. plus Gymnadenia s.l.) within subtribe Orchidinae is an important element of the North-temperate orchid flora and has become a model system for studying the genetic and epigenetic ... -
Monitoring of Insecticide Resistance in Myzus persicae from Greece
Cox, D; Devonshire, A; Denholm, Ian; Foster, S. (Ecole Nationale Superieure Agronomique de Rennes (ENSAR), 2004-01-01) -
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 ... -
Negative cross resistance mediated by co-treated bed nets: a potential means of restoring pyrethroid-susceptibility to malaria vectors
White, M T; Lwetoijera, D; Marshall, J.; Caron-Lormier, G; Bohan, D. A.; Denholm, Ian; Devine, GJ (2014-05-01)Insecticide-treated nets and indoor residual spray programs for malaria control are entirely dependent on pyrethroid insecticides. The ubiquitous exposure of Anopheles mosquitoes to this chemistry has selected for resistance ... -
