Abstract

The predatory mites Neoseiulus barkeri, Amblyseius swirskii and Cydnoseius negevi are native phytoseiid mites in Egypt. The biology of these predators was studied using Achroia grisella eggs as food source. Tested phytoseiids were succeeded to develop to adulthood and sustain oviposition on A. grisella eggs. For Cydnoseius negevi, the development was slower and fecundity was lower than for Neoseiulus barkeri and Amblyseius swirskii. The predation rate during immature stages of Cydnoseius negevi was higher than those of Neoseiulus barkeri and Amblyseius swirskii. During oviposition period, N. barkeri consumed more eggs than other phytoseiids did. The higher mean fecundity was recorded for Neoseiulus barkeri and Amblyseius swirskii as opposed to the lower mean for Cydnoseius negevi. When Amblyseius swirskii fed on Achroia grisella eggs, the oviposition period, female longevity and mean generation time were longer than for Cydnoseius negevi and Neoseiulus barkeri. Feeding on eggs of Achroia grisella resulted in the lowest mean fecundity, net reproductive rate, intrinsic rate of natural increase, finite rate of increase and gross reproductive rate for Cydnoseius negevi. The sex ratio of all predators' progeny was in female-biased. Consequently, the moth egg was alternative food for Neoseiulus barkeri and Amblyseius swirskii, while it considers as survival prey for Cydnoseius negevi.
