Abstract
Sorne aspects of the biology of the predaceous mite Euseius concordis (Chant) were studied under laboratory conditions. Similar biological cyCles and oviposition rates were observed when predator was fed Aculops lycopersici (Massee) or Ricinus communis L. pollen. On the average, E. concordis fed on 1.4 ± 0.3 active individuals of A. lycopersici per hour, spending about 55 ± 22 seconds on each. The activity of the predator was hindered by the webbing produced by Tetranychus evansi Baker and Pritchard.
