Developmental time, predation, and reproduction of Phytoseiulus persimilis Athias-Henriot from Hatay on a diet of Tetranychus cinnabarinus Boisduval larvae and protonymphs at temperatures of 20, 25, and 30 °C (75% ± 10% RH and a 14:10-h L:D (light:dark) cycle) were studied. P. persimilis females feeding on T. cinnabarinus larvae completed development in 8.12, 5.79, and 3.88 days at 20, 25, and 30 °C, respectively, during which time the females consumed on average 16.10, 16.09, and 17.18 T. cinnabarinus larvae, respectively. Alternatively, P. persimilis females completed development at the same 3 temperatures in 8.16, 5.73, and 4.27 days, respectively, on a diet of T. cinnabarinus protonymphs, and during development the females consumed 12.84, 9.69, and 12.21 T. cinnabarinus protonymphs, respectively. Mean daily consumption of adult P. persimilis females was 11.85, 20.64, and 15.41, while P. persimilis males consumed 2.41, 2.60, and 3.25 T. cinnabarinus larvae at 20, 25, and 30 °C, respectively. Females laid on average 1.85, 3.42, and 2.30 eggs per female per day, respectively, at the above-mentioned temperatures. Higher temperatures shortened the development time of P. persimilis, but the amount of food consumed was mainly influenced by diet type.
