Bdella tropica Atyeo (Acari: Bdellidae) is an efficient predator of the black flat springtail, Xenylla longauda Folsom (Collembola: Hypogastruridae). It preys on all life stages of the prey, except the eggs. In this paper we show the effect of temperatures on the predation efficiency of the adult female B. tropica feeding on adult females of X. longauda. Equations intended to describe the effect of five different temperatures on the functional response of B. tropica to X. longauda were derived from the data. The predation efficiency of B. tropica on X. longauda increased along with rising temperatures. The implication of these results for biological control of springtail (X. longauda) in edible fungi is discussed.

Key words: Bdella tropica Atyeo, Xenylla longauda Folsom, functional response, biological control
