Fecundity and reproductive activity of 179 females of Argas (A.) reflexus in laboratory conditions, i.e. at temperature 23 ± 1°C and 75% of relative humidity were observed. Under these conditions reproduction activity of females fed in spring lasted since March till August. However, most of females (63.0-91.8%) laid eggs in June and July. Disturbances in egg-laying process of Argas (A.) reflexus females fed in abnormal time, i.e., in autumn and kept in laboratory conditions, were stated. These females were active since December till July (maximum activity was observed in February-34.3% and March-40.0%). Preoviposition and oviposition periods were observed in this study, too.
