LIMITED MULTIPLE-MATING IN MALES AND SINGLE-MATING IN FEMALES OF THE ANT SPECIES, PARATRECHINA-FLAVIPES (FR SMITH) (HYMENOPTERA, FORMICIDAE)

This study determined how many times alates of Paratrechina flavipes (Hymenoptera: Formicidae) can copulate in the field and laboratory. In the field, females preferred to mate once and the mating number of males is unknown. In the laboratory, females mated singly but males could inseminate two or three females. The duration of succeeding copulations was greater than the first copulation. Multiple mating males died sooner than single mating ones. The results suggest that male death is promoted by sperm consumption.
