摘要：

Seasonal changes in the abundance and sex ratio in the hog slater were monitored in nature throughout the annual cycle. It was shown that the sex ratio was balanced at a relatively low abundance in the autumn-winter period. The number of males could exceed 1.5-fold that of females during the period of mass reproduction in spring and summer. The experimental results suggest that the summer shift of sex ratio towards males was due to their higher tolerance to elevated temperature at the early ontogenetic stages.
