These defensive secre tions contain steroids posses sing hormonal properties. The beetles offer a somewhat uni- que opportunity to investi gate the mechanism of the biological conversion of chol- esterol into active mammali an hormones, Dr. Ralph O. Mumma of Penn State described his pre- liminary studies with diving water beetles (lytiscidae fam- ily) at the 162nd national meeting of the American Chemical Society Sept. 15 in Washington, D. C. The dytiscide beetles have evolved a specialized gland, he indicated, to convert diet- ary cholesterol into com- pounds offensive to aquatic vertebrates such as frogs and fish. When swallowed by fish or frogs, the beetles excrete a viscous, milky liquid which generally causes the beetles to be regurgitated alive. The defensive secretion of the beetle contains the ster- oid cortexone; a highly active regulator of the sodium-potas- sium ion balance in mam- mals. Cortexone has been isolat- cated immediately behind the insect as well as from the pro head, and from the secretions thoracic defensive glands lo- themselves.
