Response of [alpha]-glucosidase in gypsy moth larvae to acute and chronic dietary cadmium

We investigated the effects of acute and chronic treatments with cadmium at 10 ...g Cd/g dry food and 30 ...g Cd/g dry food on α-glucosidase activity of the 4th instar larvae of Lymantria dispar (Lepidoptera: Lymantriidae) as well as subsequent recovery. Enzyme inhibition was recorded during acute e...

Description
Summary:We investigated the effects of acute and chronic treatments with cadmium at 10 ...g Cd/g dry food and 30 ...g Cd/g dry food on α-glucosidase activity of the 4th instar larvae of Lymantria dispar (Lepidoptera: Lymantriidae) as well as subsequent recovery. Enzyme inhibition was recorded during acute exposure to 30 ...g Cd/g dry food and during chronic treatment at the lower metal concentration. After three days recovery from 10 ...g Cd/g dry food, the α-glucosidase activity returned to the control level. One-way ANOVA showed that cadmium significantly influenced the activity of α-glucosidase during all treatments. The index of phenotypic plasticity was higher during chronic treatment at 10 ...g Cd/g dry food than at 30 ...g Cd/g as well as during the recovery. We detected four glucosidase isoforms by NATIVE PAGE. The activities and expressions of the isoforms depended on both larval genotype and cadmium treatment.
