Although chiggers are severe pests in many parts of the world and are important disease vectors in a large area of the Far East, detailed life history studies have so far been published only for the Japanese species. Life history studies of this group have a peculiar importance from the standpoint of disease transmission, since an individual chigger feeds on a vertebrate host only once during its entire life, and in only one stage, the larva. The disease organisms must, therefore, pass from the larva of one generation through all the successive stages, including the egg, to the larva of the next generation. In the present paper the life history of one of the species of chiggers most commonly encountered in Panama is discussed.

Annals of the Entomological Society of America is published in January, March, May, July, September, and November. Annals especially invites submission of manuscripts that integrate different areas of insect biology, and address issues that are likely to be of broad relevance to entomologists. Articles also report on basic aspects of the biology of arthropods, divided into categories by subject matter: systematics; ecology and population biology; arthropod biology; arthropods in relation to plant diseases; conservation biology and biodiversity; physiology, biochemistry, and toxicology; morphology, histology, and fine structure; genetics; and behavior.
