En el Perú, la “pulguilla de la papa”, Epitrix yanazara Bechyné se presenta como uno de los problemas potenciales de plagas en el cultivo de papa en ciertas localidades de la región andina y cuando no se utilizan aplicaciones de insecticidas para el control del gorgojo de los Andes. Esta plaga s...
In Uganda, weather-related events such as prolonged dry seasons, floods, storms, mudslides, extreme rainfall, and delayed/early rains have become more frequent and/or intense. This has left most of the rural poor farmers’ food insecure and their livelihoods threatened. A total of 192 sweetpotato ...
Potato production systems face constant changes in climate conditions and the projections for the future indicate that changes in temperature and precipitation are expected in certain regions of the world. The impact will depend on what we do today to avoid negative consequences. Climate projecti...
Originating from the Andean region and co-evolved with its food plant, the potato (Solanum sp.), the potato tuber moth Phthorimaea operculella (Zeller) has become an invasive potato pest globally. The hypothesis of our present study was that the future distribution and abundance (damage potential...
If climate change scenarios include higher variance in weather variables, this can have important effects on pest and disease risk beyond changes in mean weather conditions. We developed a theoretical model of yield loss to diseases and pests as a function of weather, and used this model to evalu...
