Etude de l'efficacité prédatrice de Zetzellia mali (Acarina, Stigmaidae) vis-à-vis du tétranyque du pommier Panonychus ulmi (Acarina, Tetranychidae). Entomphaga, 19 (1): 13-31.

Abstract
Assessment of the predatory effectiveness of Zetzellia mali EwrNG. (Acarina Stigmaeidae) towards the apple mite Panonychus ulmi Koen. (Acarina Tetrany­chidae). This predatory effect was assessed by observing natural populations of mites, according to several ecological criteria. The results of this study outlines the fairly important effect of the predatory mite Zetzellia mali on the prey populations, thus proving the interest of maintaining some sedentary useful animals of this type in the orchards. Some data have been collected in order to help the predatory activity of this mite in commercial orchards.
