Figure 1 From: Immune system responses and fitness costs associated with consumption of bacteria in larvae of Trichoplusia ni Enzyme activities in the hemolymph of last instar T. ni larva, fed on bacteria-free (-BAC) and bacteria-supplemented diet (+BAC). (A) General antibacterial activity measured as the diameter of the lytic zone on agar plates and transformed into lysozyme equivalents (μg/ml). (B) Phenoloxidase activity (slope at Vmax) measured from hemolymph samples. Results represent mean values ± SE.Back to article page
