In Amblyseius barkeri a relation was found between the duration of copulation and the resulting egg production. After 15 min of copulation no eggs were produced but after respectively 30, 60, 120, 180 min an increasing number of eggs were deposited. A male showed a high reproductive ability for more than 16 days and was able to mate more than once in excess of females, with maximum of six times. The effect of single and multiple mating on longevity, fecundity and sex ratio of the predacious mite Amblyseius barkeri (Hughes) was studied. Fecundity of females mated more than once was twice as females mated only once
