Beta adrenergic receptors promote and alpha adrenergic receptors inhibit insulin secretion.When adrenergic nerve supply to pancreas is stimulated( ex: during prolonged strenous exercise) the effect of alpha receptors predominates and therefore insulin secretion is inhibited.

this is equivalent to what happens in flight and fright, glucogenic hormones are increased over insulin.
