Studies on chill coma recovery in the ladybird, Harmonia axyridis: Ontogenetic profile, effect of repeated cold exposures, and capacity to predict winter survival

Popis výsledku v původním jazyce

The harlequin ladybird, Harmonia axyridis, is one of the most successful invasive insect species worldwide. We investigated whether (i) chill coma recovery time (CCRt) changes during the ontogenetic development of this species, (ii) CCRt varies in response to repeated cold shocks, and (iii) CCRt could be a good predictor of winter survival ability in adults. CCRt decreased during larval development, the lowest CCRt values were observed in teneral adults (one and four days old), and significantly higher values were observed for older adults (16 and 32 days old). Repeated cold shocks (two hours at -3 degrees C), interrupted by short (30 min) warm periods (22 degrees C) resulted in decreased CCRt after the second cold shock, probably depicting an acclimation response, but then CCRt increased with additional cold shocks, likely revealing the accumulation of chill injuries. The CCRt of pre-overwintering individuals was not correlated with their winter survival. This indicates that CCRt is not a reliable m
