| Abstract | ||||
| Field experiments were conducted to determine the efficacy of three predators- Phytossulus persimilis, Neoseiulus californicus and Orius albidipennis, two pathogenic fungi- Metarhizium anisopliae andPaecilomyces fumosoroseus and Azadrachtin at single and combined releases against two spotted spider mite, Tetranychus urticae on sweet pea, Lathyrus odoratus crop during two consecutive seasons, 2016/2017 and 2017/2018 at Behera Governorate, Egypt. Highly reduction percentages in the population of T. urticae stages was stated with the combined treatment of Ph. persimilis +N. californicus,followed by Ph. persimilis + M. anisoplie and Ph. persimilis + P. fumosoroseus. The combined releasing of Ph. persimilis + O. albidipennis, and each of M. anisoplie, P. fumosoroseus, and Azadrachtin had the lowest effect of reducing T. urticae populations. | ||||
