Three sister broods were established at 600 and 800 m a.s.l., in both years, while only two occurred at 1100 m a.s.l. in 2011. A third sister brood at 1100 m a.s.l. was recorded only in 2012. Up to100% of females re-swarmed during first re-emergence. Second and third sister broods were established by 8–90% and 0–22% of females, respectively. The number of established broods is highly correlated with infestation density. Data recorded in this study were compared with similar studies conducted in 1950s by Martinek (1956, 1957, 1961). The influence of climate change and rising temperature averages upon number and intensity of sister broods is discussed as a possible explanation.
