A scheme of a mixture of normal laws of weight distribution in O. ovis larvae of various stages was used for the determination of their mortality and for the evaluation of basic distribution parameters. No mortality was observed in 2nd- and 3rd-instar larvae. The distribution of the number of 1st-instar larvae corresponded to the negative binomial distribution. The weight distribution correlated with the quantitative distribution of the 1st-instar larvae. The present studies are based on results obtained during investigations of ovine oestrosis in Stavropol Territory (Russia) and the Kalmyk ASSR performed by K.A. Breev and his coworkers in 1976-77.
