Abstract

In the present study, the Phytoseiidae mite’s species namely; (Neoseiulus cucumeris, Neoseiulus californicus, Phytoseiulius persimilis, Typhlodrompis swirskii, Typhlodromus nigavi) as well as vertemic as a bio-insecticide, were tested for controlling the phytophagous mites Tetranychus urticae Koch that infest tomato plants (Rogina cultivar) in Egyptian governorates namely, El-Beheira, El-Fayum and El-Ismailia. Obtained results indicated presence of significant differences among efficacies of all evaluated predators including vertemic, compared to untreated checks (control) and that T. swirskii was the highest potent treatment followed by N, californicus and vertemic which were significantly differed compared to the control (non-treated check, P<0.001).
