Abstract

The life history of the spider mite, Tetranychus cucurbitacearum (Sayed) was investigated on six eggplant cultivars ("White", "Black Stream beity", "Baladi", "Black king", "Roma" and "Taska") at 25 & 35+2°C and 70+5% R.H. "Taska" cultivar shortened the life cycle to 10.08 and 6.93 days at25 and 35'C; while "White" cultivar prolonged this period to 16.28 and 10.61 days. The high egg production per female was on Taska cultivar (70.70 & 47.58 eggs) with a daily rate of 7.08 & 5.50 egg/female at25 and 35°C, respectively. The low egg production per female was on White cultivar (41 .66 & 29.42 eggs) with a daily rate 7 .38 & 7 .99 egg/female, respectively at the same previous conditions.
