Eric Wajnberg is a research scientist working at the Institut National de la Recherche Agronomique (INRA), Sophia Antipolis, France. He is a population biologist specializing in behavioural ecology, population genetics and statistical modelling. He is also an expert in biological control, with almost 30 years experience working on insect parasitoids.Stefano Colazza is based at the University of Palermo, Italy. He is a specialist in infochemicals and behavioural ecology of plant, insect herbivores, and insect parasitoid interactions, with a special interest in the chemical ecology of plant volatile organic compounds in a tri-trophic context. He has been involved in these research areas for over 30 years.
