Abstract

Determination of biology of predatory mite Typhlodromips (Amblyseius) enab El-Badry (Acari: Phytoseiidae) at different temperatures Biology of predatory mite Typhlodromips enab El-Badry (Acari: Phytoseiidae) were studied at different temperatures under laboratory conditions. Predatory mite females completed their total immature development times in 8.68, 6.15 and 4.73 days at 20±1, 25±1 and 30±1 oC, respectively (70±10% RH and 14L: 10D lightning period). Mated females laid an average 0.88, 0.57 and 0.64 eggs per female per day and 4.40, 4.63 and 6.40, eggs over their the entire lives in the above given temperatures, respectively. Total average life span of T. enab was 21.80, 16.49 and 15.20 days at 20, 25 and 30 oC, respectively. Food consumption and reproduction of the predatory mite did not show the increasing action according to increasing food density. Predatory mite comsumption changed between 0.70 to 6.40 while reproduction changed between 0.30 – 0.70 eggs/daily, at different prey densities. According to results, predatory mite completed its development on a diet of Tetranychus cinnabarinus Boisduval (Acari: Tetranychidae) but this pest is not a suitable diet for reproduction of this predator
