Abstract
Eight phytoseiid species were tested to evaluate their potential as predators of Tuta absoluta (Meyrick) eggs as an alternative/natural food source under laboratory conditions. Predatory phytoseiid mites were, namely: Typhlodromips swirskii (Athias-Henriot), Euseius scutalis (Athias-Henriot), Cydnoseius negevi (Swirski and Amitai), Neoseiulus barkeri (Hughes), Neoseiulus californicus (McGregor), Phytoseius finitimus Ribaga, Proprioseiopsis badri (Yousef and El-Borolossy) and Amblyseius largoensis (Muma).Immatures survival of tested phytoseiid species were low on eggs of T. absoluta and all failed to develop to adulthood.Adult females of C. negevi, A. largoensis and N. barkeri were able to feed and sustain oviposition on eggs of T. absoluta. A diet of insect eggs provided the shortest oviposition period and adult longevity of C. negevi, while A. largoensis showed the longest corresponding periods. The total and daily number of insect eggs consumed was significantly higher in N. barkeri and C. negevi than i...
