Yousef, A.E.T.A., & El Halawany, M.E. 1982 Effect of prey species on the biology of Amblyseius gossipi El Badry (Acari: Mesostigmata: Phytoseiidae).. Acarologia 23(2): 113-117.

Notes: In laboratory feeding experiments in Egypt, the effect of prey species on the life-span, efficiency and fecundity of Amblyseius gossipi El Badry was studied in an incubator at 25 deg C. The male usually emerged before the female, but both emerged together if fed on the eggs of Tetranychus urticae Koch or Eutetranychus orientalis (Klein). The females lived longer and captured many more prey than did the males. The eggs of mites as food, especially those of T. urticae, induced more rapid development and higher fecundity in the predator than did other immature stages of mites, but the highest daily mean egg production was observed in predators fed on immature stages of Chrysomphalus aonidum (L.). Over 90% of the total number of prey taken by an individual of A. gossipi was consumed during the adult stage, and the highest rate of predation was observed in the female during the oviposition period. Lepidosaphes beckii (Newm.) and Icerya purchasi Mask. were the least preferred prey species; predators offered only these ate the smallest numbers, laid fewest eggs and had the shortest life-span.
