Biography
Ale's research focuses on insect ecology at multiple spatial scales in human-dominated landscapes, with emphasis in ecosystem services, sustainable management of agricultural pests, and biological control. Current research projects include studying impacts of natural enemies on soybean aphids, fitness of different morphs of soybean aphid, effects of landscape structure on parasitism and predation of cereal leaf beetle, and mechanisms of plant resistance to wheat midge.
Research Interest
Arthropod-mediated ecosystem services, Effects of landscape structure on agricultural pests and beneficial insects, Plant resistance to insect pests, Bottom-up and top-down controls of herbivores, Trophic cascades in agroecosystems, Intraguild predation, Biological control and integrated pest management, Food webs
