Abstract
Biological characteristics, life table parameters and predation rate of the predatory mite Neoseiulus californicus (McGregor) under the laboratory conditions of 25 ± 2°C, 75% R.H. and photoperiod of 12L: 12D was studied. Prey types were Brevipalpus phoenicis (Geijskes) motile stages, Tetranychus urticae Koch eggs and motile stages and Tegolophus guavae (Boczek) motile stages. The predator completed developmental stages on tested prey types with a life cycle of
7.02 to 10.25 days. Its developmental time was significantly affected by prey species as T. urticae motile stages shortened its development more than other ones. Female longevity ranged between 16.70 and 28.2 days. Longest female longevity and highest fecundity one was recorded on T. urticae motile stages (49.3 eggs/female), whereas lowest fecundity (12.6 eggs/female) was recorded on motile stages of T. guavae. The highest consumption rate of adult female was 496.2 individuals when fed on T. guavae; while the lowest was 161.2 individuals on T. urticae motile stages. Net reproduction rate of increase (Ro), intrinsic rate of natural increase (rm) and finite rate of increase (λ) were highest on T. urticae motile stages as 35.59, 0.272 and 1.31, respectively.
