Popis: The influence of rice moth, Corcyra cephalonica Stainton (Lepidoptera: Pyralidae) eggs on the development, survival and reproduction of four predatory phytoseiid mites was studied under laboratory conditions. Amblyseius largoensis (Muma) successfully developed and reproduced on C. cephalonica eggs, while protonymphs of Neoseiulus barkeri (Hughes), Cydnoseius negevi (Swirski and Amitai) and Typhlodromips swirskii (Athias-Henriot) failed to develop beyond the protonymphal stage. Adult females of all tested phytoseiid mite species were able to feed and sustain oviposition on eggs of C. cephalonica. A diet of insect eggs provided the shortest oviposition period and adult longevity of C. negevi and A. largoensis, while T. swirskii showed the longest periods in this respect. Preying on moth eggs gave the highest consumption and fecundity rate for N. barkeri and T. swirskii in comparison to A. largoensis and C. negevi, which showed the lowest value. The sex ratio of the progeny was strongly female biased when insect eggs were provided for tested phytoseiid mites. These differences in response to the factitious host insect eggs should be considered for the production of healthy cultures of A. largoensis.
