CHANGES IN TEMPERATURE IN THE HALL OF AULACIDEA HIERACII (HYMENOPTERA: CYNIPIDAE) ON THE PLANT HIERACIUM ROBUSTUM (ASTERACEAE) IN WINTER PERIOD
Conducted field experiments in winter period with temperature extremes has allowed to establish the differences in the indicators of air temperature and the temperature inside the gall (gallformer Aulacidea hieracii) on mighty hieracium (Hieracium robustum). For hourly fixing temperature of atmospheric air and the temperature inside the gall was used by the author collected device data logger. When comparing the ambient temperature and the temperature inside the gall by Wilcoxon criteria for samples with pairwise coupled variants were marked statistically significant differences (Z=3.61; p=0.0003). The differences confirmed by the criterion of signs (Z=2.33; p=0.02), which confirms the reliability of the differences of temperature inside the gall and outside on air, which is caused, apparently, thermal properties of gall. During the field experiment, the authors found that with significant sharp fluctuations in atmospheric air (12 degrees per day), within the gall there are minor fluctuations (no more than 4–5 degrees).
