    The impact of acclimation and fluctuating thermal regimes on the cold tolerance of the tropical beetle Alphitobius diaperinus was examined. Acclimation at 15°C increased significantly the survival at a constant 5°C. Survival increased at alternating temperatures (5°C / 10 or 15 or 20°C). The effect of chilling was repaired completely at 25 and 30°C. The theoretical upper threshold of chill injury was 15°C in non-accliamted and 11°C in acclimated beetles

    Vliv aklimace a kolísavých teplot na chladovou odolnost byl studován u tropického brouka Alphitobius diaperinus. Aklimace v 15°C zvýšila následné přežívání v 5°C. Přežívání se zvyšovalo v kolísavých teplotách (5°C / 10 nebo 15 nebo 20°C). Chladové poškození bylo zcela opraveno při 25 a 30°C. Teoretický horní limit poškození chladem byl 15°C pro neaklimované a 11°C pro aklimované brouky
