Biology of Bdella depressa, a Predaceous Mite1

Prostigmata (Acari: Trombidiformes) as Biological Control Agents

“…Snetsinger ( 1956 ) observed that Spinibdella depressa (Ewing) required 21-30 days to develop from larva to adult at 15.5 °C, and from 14 to 21 days for development at 21.1 °C, in both cases feeding on the spider mites Tetranychus urticae Koch and Bryobia praetiosa Koch. Spinibdella depressa was also reported (Snetsinger 1956 ) to feed on the spider mites Petrobia harti (Ewing), Petrobia latens (Müller) and Schizotetranychus sp., in addition to the springtails Bourletiella hortensis (Fitch) and Willowsia platani (Nicolet). Spinibdella bifurcata Atyeo required 24-164 days to develop from larva to adult, depending on the season in which the experiment was carried out (Soliman and Mohamed 1972a ).…”

“…A few other studies were conducted later, to evaluate the infl uence of diets and temperature (Snetsinger 1956 ;Soliman and Mohamed 1972a , b ;Foster et al 1979 ;Sorensen et al 1983 ;King 1985 , 1986 ;Ji et al 2007aJi et al , b , 2012Chen et al 2007Chen et al , 2008Chen et al , 2011.…”

“…The study of Womersley (1933c), in which he reports Odontoscirus lapidaria (Kramer) as a potential predator of Sminthurus viridis (L.) in pastures of Australia is probably the first example of pest control by a mite. Other studies focusing on the development and other biological aspects were done by Snetsinger (1956), Soliman & Mohamed (1972a, b), Foster et al (1979), Sorensen et al (1983), and Ernst (1995).…”

“…He also recovered specimens of C. latirostris. Snetsinger (1956) reported 8. depressa as an important predator of the clover mite on the bark of trees and in grassy areas in Illinois. Cyta latirostris and 8. depressa were both reported by Moser and Roton (1971) in bark samples of pine bark beetle.…”
