[Effect of the photoperiod and temperature on the fertility of different generations of the blood-sucking fly, Culicoides pulicaris punctatus (Ceratopogonidae)].

It was established that the fecundity of females of different generations of C. p. punctatus, which are at the 1st gonotrophic cycle, is unequal. There was noted a decrease of the per cent of realisation of potential fecundity in females of the summer-autumn generation. The dependence of the virtual fecundity on the day length and temperature was studied. The differences in ther effect of these factors on the fecundity of females of the spring-summer and summer-autumn generations were found.
