The painted leafhopper, Endria inimica (Say), a vector of wheat striate mosaic virus, is a bivoltine insect that overwinters in nature as 2nd generation eggs in diapause. In the laboratory, egg diapause occurred when females were reared under short day lengths (12L:12D); diapause was averted by rearing females under long days (15L:9D). Eggs in diapause were not induced to develop by exposing them to the light and temperature conditions favorable to continuous development, but developed only after chilling. Diapause was terminated more rapidly by chilling the eggs at 0° than to 8°C.

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.
