Biological characteristics and life table parameters of Orius albidipennis on strawberry spider mite Tetrannychus turkestani at different temperatures

The strawberry spider mite, Tetranychus turkestani (Ugarov & Nikolski) is one of the important pests of agricultural crops especially within grean houses. Biology ane life table parameters of Orius albidipennis (Reuter) feeding on strawberry spider mite at three different temperatures (20, 25 and 300C) was studied under laboratory conditions. Preimaginal developmental time of this predator at 20, 25 and 300C was 34.54, 16.82 and 11.68 days for females and 31.83, 16.1 and 11.89 days for males, respectively. Preimaginal mortality was 30, 28.12 and 17.25% at above mentioned temperatures, respectively. Sex ratio (female %) was 46, 51 and 48 % at at above mentioned temperatures, respectively. Adult longevity of female and male at 20 and 250C was 26.22 16.7 and 22.43, 13.22 days, respectively. Total egg production of females at two above mentioned temperatures was 50 and 39 eggs, respectively. Intrinsic rate of increase of this predator at two respected temperatures was 0.124 and 0.165, respectively. Generation time of O. albidipennis was 23.59 and 16.37 days, respectively. Our results showed that O. albidinnis has enough potential to control T. turkestani.
