Invertebrate organisms that live on or in another organism (the host), and benefit at the expense of the other. Traditionally excluded from definition of parasites are pathogenic bacteria; fungi; viruses; and plants; though they may live parasitically. [NALT]
An organism that lives at the expense of another (host) during some portion of its life cycle. Usually a parasite does not kill its host. [AGROVOC]

An ectoparasite lives outside the host's body, on the host's surface. [<a href="http://aims.fao.org/aos/agrovoc/c_10532">AGROVOC</a>]

The Department of Entomology and Nematology maintains tripartite priorities consistent with the mandate given to full-service landgrant universities and associated experiment stations: <a href="https://entnemdept.ufl.edu/research-areas/department-research-areas/" target="_blank" rel="noopener">Research</a>, <a href="http://entomology.ifas.ufl.edu/extension/" target="_blank" rel="noopener">Extension</a>, and <a href="https://entnemdept.ufl.edu/academic-programs/academics-directory/" target="_blank" rel="noopener">Academics</a>. These programs are facilitated with state funding, extramural contract and grant funding, donations and gifts, and the collaborative efforts of cooperating agencies and institutions. The Department has coordinated faculty efforts and strengths into what could be considered major thrust areas for the Department. These areas of emphasis include: Behavior, Ecology, and Systematics; Biological Control; Medical, Veterinary and Urban Entomology; Nematology; Pest Management; and Physiology, Biochemistry, and Genetics.
