Extract

Female black flies may be sorted into two age groups, the nulliparous and the parous, by the changes in the ovary including the absence or presence of follicular relics. This highly accurate method, developed in Russia and England for Anopheles mosquitoes (Beklemishev 1944; Lewis 1958a), has been recently adapted for use with black flies (Lewis 1958b; Davies 1961).
