Abstract:Podisus acutissimus Stal is a predaceous pentatomid found only in the southwestern United States though it has a wider range in Mexico. Butler and Werner (1957, 1960) reported that the prey is unknown, the insect has rarely been collected in the field, and the species has been sparingly reported in the literature. However, they collected 23 of the insects in 381 samples taken during 1954–56 from alfalfa, cotton, barley, sorghum, and other plants in the Arizona counties of Maricopa, Pinal, Pima, Santa Cruz, Cochise, and Greenlee. We have collected only 16 P. acutissimus in a total of 76,879 sweeps made weekly in alfalfa in Pima County, but P. acutissimus was present in June through Sept. 1970, Oct. and Nov. 1971, and April 1972. (These collections were made in a search for several insect species of which P. acutissimus was one.) Subsequently, we determined (Stoner et al. 1974) that P. acutissimus developed partially (with moderate survival) on plant foods, but no adults emerged on a diet of plant food alone. Also, all nymphs reached the 2nd stadium on water alone; they do not feed as 1st instars.

- 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.
