Abstract: Two factors were examined to determine their effect on the reproduction and sex ratios in the predacious mite Amblyseius barkeri, in the laboratory. The factors investigated included age of mating females, and food deprivation periods during the immature and adult stages. Age of females has an influence on fecundity and sex ratio; old females decreased egg production and produced proportionally more male progeny compared with young females under constant condition of abundant prey. A significant lower fecundity was recorded on females when exposed to different food deprivation programmes, as well as the longevity periods apparently affected by starvation.
