Effect of acrylonitrile on trehalase, phosphorylase and acetylcholinesterase activities in Tribolium castaneum Herbst and Trogoderma granarium Everts.

Acrylonitrile inhibited trehalase and phosphorylases in larvae and adults of Tribolium castaneum. In Trogoderma granarium larvae phosphorylases alone were inhibited. Acetylcholinesterase was not affected.
