The mate-receptivity behavior and reproductive capacity of single- and multiple-mated females of a predacious mite, Amblyseius womersleyi, were examined. Although most females rejected a second mating within one day after the first mating (1 day later), they accepted it towards the end of the oviposition period (10 days later). Females that had experienced full copulation twice produced significantly more eggs than those that had mated only once. All females that had copulated with a sterile male which had lost its ability to fertilize a female following a series of multiple matings, showed a positive response toward the second copulation on the next day. These results suggest that acquisition of sperm or seminal fluids is probably a critical factor for mating receptivity and that multiple matings are required in order to reach the full reproductive capacity for A.womersleyi females.
