Effects of limited volatiles release by plants in tritrophic interactions
(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 ... -
Forewarned is forearmed: harmonized approaches for early detection of potentially invasive pests and pathogens in sentinel plantings
(Journal article; Peer reviewed, 2019-06-21)The number of invasive alien pest and pathogen species affecting ecosystem functioning, human health and economies has increased dramatically over the last decades. Discoveries of invasive pests and pathogens previously ... -
From leaf to continent: The multi-scale distribution of an invasive cryptic pathogen complex on oak
(Journal article; Peer reviewed, 2018-09-12)The spatial distribution and niche differentiation of three closely related species (Erysiphe alphitoides, Erysiphe quercicola and Erysiphe hypophylla) causing oak powdery mildew was studied at scales ranging from the ... -
