Decrease in juvenile hormone level as a result of genetic ablation of the Corpus allatum cells affects the synthesis and metabolism of stress related hormones in Drosophila

► Genetic ablation of Corpus allatum (CA) cells increases dopamine content. ► CA ablation decreases tyrosine hydroxylase activity and stress reactivity. ► CA ablation decreases alkaline phosphatase activity and stress reactivity. ► CA ablation decreases DA-dependent arylalkylamine N-acetyltransferase activity. ► CA ablation increases tyrosine decarboxylase activity and stress reactivity.
