Abstract
Biology, life table parameters and predation efficacy of phytoseiide mite, Cydnoseius negevi  for controlling eriophyid mite, Aculus lycopersici and Bemisia tabaci  on eggplant, Solanum melongena under laboratory and open field in Egypt was studied. The shorter female developmental time and longevity occurred when fed on A. lycopersici (8.16 and 21.08 days, respectively).  The longer was on B. tabaci (9.20 and 26.90 days, respectively). Fecundity and daily oviposition rates were the higher on A. lycopersici as 34.15 eggs/female and 2.32 eggs/female/day. The lower were 25.30 eggs/female and 1.2 eggs/female/day on B. tabaci. The higher intrinsic rate of increase (rm) and net reproductive rate (R0) were 0.182 females/female/day and 15.87 females/female on A. lycopersici. Total predation of C. negevi male and female was 187.0, 249.5 prey for A. lycopersici, and 174.73 and 227.3 prey for B. tabaci, respectively. The efficiency of C. negevi was investigated at three rates of predator: prey release (1:3, 1:5 and 1:10) under open field on the two pests. The higher mean reduction percentage of A. lycopersici after six weeks of release was 85.71, 86.13 and 69.63; and 84.16, 77.36 and 63.31% for B. tabaci, respectively. The results suggested that C. negevi can be considered a good predator of eggplant piercing and sucking pests.
