The method of statystical analysis of the distribution of the 2nd and 3d instar larvae of Hypoderma bovis in 54 herds (8120 heads) of cattle from Czechoslovakia and in 20 herds (1809 heads) from Mongolia has shown that in most cases the negative binomial distribution models the distribution of larvae with sufficient reliability and that the variability in parameters of the distribution is stable independent on the parts of the area.
对来自捷克斯洛伐克的54个牛群（8120头牛）和来自蒙古的20个牛群（1809头牛）中的牛皮蝇二龄和三龄幼虫分布进行统计分析的方法表明，在大多数情况下，负二项分布能以足够的可靠性模拟幼虫的分布，且分布参数的变异性稳定，与该地区的不同部分无关。
