Incidence, abundance and damage by the sweet potato butterfly (Acraea acerata Hew. and the African sweet potato weevils (Cylas spp.) across an altitude gradient in Kabale district,... por Okonya, J., Kroschel, Jürgen

“…It is increasingly becoming important to understand relationships between temperature (manifested at different altitude levels) and sweet potato insect pest characteristics in light of temperature changes as a result of global warming. Field surveys were conducted in Kabale district of Uganda along an altitude gradient to study the effects of temperature on incidence, abundance and level of damage by main sweet potato insect pests, the sweet potato butterfly (Acraea acerata Hew.) and the African sweet potato weevils (Cylas puncticollis Boheman and Cylas brunneus F.), respectively. …”
