Abstract

The influences of single and multiple matings on egg production in the two predacious mitesAgistemus exsertus Gonz. andPhytoseiulus persimilis Ath. — Hen. were investigated in the laboratory. with both species egg production was increased as a result of multiple matings, but this increase was insignificant. In addition, mated females ofA. exsertus commenced oviposition one day earlier compared to unmated ovipositing females.
