Are fungal epizootics a sign of successful biological control of cereal aphids?
Saussure, Stephanie; Hjelkrem, Anne-Grete Roer; Klingen, Ingeborg; Meadow, Richard; Holst, Niels (Peer reviewed; Journal article, 2023-07-26)Pandora neoaphidis is a common entomopathogenic fungus on Sitobion avenae, which is an important aphid pest on cereals in Europe. Pandora neoaphidis is known to cause epizootics (i.e. an unusually high prevalence of infected ... -
Can aphids be controlled by fungus? A mathematical model
Britton, Nicholas F.; Bulai, Iulia Martina; Saussure, Stephanie; Holst, Niels; Venturino, Ezio (Journal article; Peer reviewed, 2019-06-21)The control of insect pests in agriculture is essential for food security. Chemical controls typically damage the environment and harm beneficial insects such as pollinators, so it is advantageous to identify targetted ... -
Effect of three isolates of Pandora neoaphidis from a single population of Sitobion avenae on mortality, speed of kill and fecundity of S. avenae and Rhopalosiphum padi at different temperatures
Saussure, Stephanie; Westrum, Karin; Hjelkrem, Anne-Grete Roer; Klingen, Ingeborg (Journal article; Peer reviewed, 2019)We studied the effect of three Pandora neoaphidis isolates from one Sitobion avenae population, three temperatures, and two aphid species namely S. avenae and Rhopalosiphum padi on (i) aphid mortality, (ii) time needed to ... -
Effects of limited volatiles release by plants in tritrophic interactions
Buonomo, Bruno; Giannino, Francesco; Saussure, Stephanie; Venturino, Ezio (Journal article; Peer reviewed, 2019-04-17)We introduce a mathematical model to describe the tritrophic interaction between crop, pest and the pest natural enemy where the release of Volatile Organic Compounds (VOCs) by crop is taken into account. The VOCs may be ...
