Elevational gradients are characterized by strong abiotic variation within small geographical distances and provide a powerful tool to evaluate community response to variation in climatic and other environmental factors. We explored how temperature and habitat diversity shape the diversity of holometabolous predator and parasitoid insects along temperate elevational gradients in the European Alps. We surveyed insect communities along 12 elevational transects that were selected to separate effects of temperature from those of habitat diversity.

Agroecological research was carried out in northern Cameroon from 2008 to 2014 to develop a strategy aiming to encourage the action of natural enemies against lepidopteran pests in cotton crops and in surrounding landscapes. Tachinidae is one of the most diverse families of Diptera in the Afrotropics and represents an important group of endoparasitoids, although their role as biocontrol agents in crops is still poorly understood in Africa.
