Bill Nelson and colleagues from Penn State University (USA) and the National Institute for Agro-Environmental Sciences (Japan) show in a new paper in the journal Science that tortrix moths experience an unusually large outbreak in population numbers when the temperature rises above 15 degrees Celsius, but are relatively stable when it’s cooler. Dr. Nelson and his collaborators used a combination of mathematical modeling and analysis of moth outbreak cycles to demonstrate the impact of temperature on population cycles.
