title: Adenosine-3',5'-monophosphate in salivary glands of unfed and feeding female lone star ticks, Amblyomma americanum (L.).
abstract: Basal levels of cAMP in salivary glands of female lone star ticks were found to be about 5 pmoles/mg protein during all stages of feeding. Glands stimulated with 10(-5)M dopamine and 10(-5)M dopamine plus theophylline exhibited significant increases in cAMP/mg protein. After stimulation by 10(-5)M dopamine was removed, cAMP decreased faster in glands from slowly feeding ticks (less than 200 mg) than in glands of rapidly feeding ticks (greater than 200 mg).
