Mechanisms influencing the evolution of resistance to Qo inhibitor fungicides.
Fungicides inhibiting the mitochondrial respiration of plant pathogens by binding to the cytochrome bc1 enzyme complex (complex III) at the Qo site (Qo inhibitors, QoIs) were first introduced to theExpand

A behavioural analysis of phase change in the desert locust
A programme of research into phase change in the desert locust, Schistocerca gregaria, is described. The ability to change phase between solitarious and gregarious forms in response to populationExpand

Evidence for p‐glycoprotein modification of insecticide toxicity in mosquitoes of the Culex pipiens complex
Abstract Pesticide resistance has parallels with multi‐drug resistance syndrome of tumours in clinical medicine, which has been linked to an ATP‐dependent pump, p‐glycoprotein (P‐gp). P‐gps pumpExpand

Effects of population density experienced by parents during mating and oviposition on the phase of hatchling desert locusts, Schistocerca gregaria
The behavioural phase state of first-instar desert locusts, Schistocerca gregaria Forskål, was quantified by using logistic regression analysis, following treatments in which the population densityExpand
