摘要: Since the preferential body temperature should positively correlate with physiological performance, behavioural fever enhance an organism's immune response under challenge. Here we have studied (T(p)) and its consequences on performance after challenge in larvae of Tenebrio molitor. We evaluated T(p) responses following a various concentrations lipopolysaccharide (LPS), correlation between two traits, namely antibacterial phenoloxidase (PO) activities. Larvae that were challenged higher LPS (C(50) C(100)) preferred average, warmer temperatures than did lower (C(0) C(25)). C(25)-C(100) (challenged)-mealworms was 2.3°C C(0) (control) larvae. At concentration C(25)) activity correlated T(p), but at C(50) C(100) lose. PO concentration, magnitude not Our data suggest may positive effect host by enhancing low pathogen load situation.
