[Effect of the population density of the tick Ornithodoros papillipes (Argasidae) on its experimental oviposition].

It has been established under laboratory conditions that in ticks O. papillipes there exists an intrapopulation regulation of their number depending on the population density. The course of the regulation is as follows: with increasing density decreases the fecundity of females, increases the mortality of eggs and imago, increases the duration of oviposition and development of eggs.
