Multiple matings of Chysolina aurichalcea (Mannerheim) (Coleoptera : Chrysomelidae)
SHIMIZU, NOBUYUKI
FUJIYAMA, SHIZUO
The existence of multiple matings in both males and females of a chrysomelid beetle Chrysolina aurichalcea was examined by measuring the total duration of copulation in one multiple-mating bout and by observing the caged population every two hours for six days. The mean total duration of copulation in one multiple-mating bout was 3.2±1.7 hrs under a plastic container. Observation for six days showed that all five females conducted an average of seven matings with three males. In case of all five males, an average of nine matings with four females were observed except two males which had performed no copulations. The significance of multiple matings of the species was discussed in relation to the effects of selection pressure on genetic variations of discreet populations.
