Abstract
The developmental time, survival, fecundity and life table parameters of the predacious mite, Lasioseius lindquisti Nasr and Abou-Awad were determined on seven different food types at 28±1° C and 70±5% RH. The food tested are, the eriophyid mite, Aceria dioscoridis (Soliman and Abou-Awad), the acarid mite, Rhizoglyphus robini Claparede, the two spotted spider mite Tetranychus urticae Koch, pollen grains of Ricinus communis L and Phoenix dactylifera L. as well as fungi of Fusarium oxysporum Snyder and Fusarium solani Snyder. Total developmental time of L. lindquisti female was shortest (7.0, 7.7, 7.2 and 8.0 days) on A. dioscoridis, pollen grains of P. dactylifera and both fungi F. solani and F. oxysporum, respectively. The total egg production rates were the highest on A. dioscoridis and pollen grains of P. dactylifera (62.7 and 46.6 eggs / ♀, respectively). A diet of A. dioscoridis showed a higher values of the net reproductive rate (Ro = 42.3375), intrinsic rate of increase (rm = 0.2902) and finite rate of increase (λ = 1.3367) per day than pollen grains of P. dactylifera and the fungus F. oxysporum. A diet of F. oxysporum fungus resulted the lowest total fecundity which resulted in the lowest the net reproductive rate (Ro = 17.9290), intrinsic rate of increase (rm = 0.1941) and finite rate of increase (λ = 1.2142)) per day for L. lindquisti. Rhizoglyphus robini, pollen grains of R. communis and F. solani fungus were considered as supplementary food for the predator L. lindquisti, since the predator able to feed and develop on above diets but failed to sustain oviposition. The sex ratio of the progeny was female biased (female / total = 0.68 and 0.62) when A. dioscoridis and pollen grains of P. dactylifera were provided to the predator. Lasioseius lindquisti failed to feed and develop on nymphs of T. urticae.
