Javad Karimi is an associate professor of insect pathology in the Ferdowsi University of Mashhad (FUM) (2008- now) which graduated from the University of Tehran (2007). His academic teaching and research interest focuses on insect pathogens as biocontrol agents with special reference to entomopathogenic nematodes (EPNs) (including their symbiotic bacteria) and insect parasitic nematodes. Hossein Madadi got his PhD degree of Agricultural Entomology at 2005 from University of Tehran and now working as associate professor of Agricultural Entomology at the Bu-Ali Sina Univ. Hamedan, Iran. His dissertation was about the role of host plants on interactions among predator-pest species.His special research field of interests is biological control of plant pests within greenhouses, Ecology of Predators (focusing on mites, bugs and beetles) and interactions among natural enemies and their hosts/Prey.
