Acrosternum impicticorne


Acrosternum impicticorne   .

This pentatomid, along with Antiteuchus tripterus (Fabricius, 1787)   , was the fifth most abundant species recovered. Adultswere captured in greater number than nymphs ( fig. 5 View Figs ). Adults increasedin numbers from Marchand peaked during May, decreasing thereafter. They were present on privet during most of the year, with numbers occurring during late spring and summer. Nymphs were captured in low numbers and only in October, December, February, and April. Because few nymphs ( fig. 20 View Figs ) and adultswere collected, no attempt was made toraise A. impicticorne   inthelaboratory. However, we suspect that nymphs will show some degree of development on privet berries, because they were observed feeding on these fruits in the field. A. impicticorne   is known as a secondary pest of soybean in Brazil, and has been collected from several states such as Distrito Federal, Minas Gerais, São Paulo, Paraná, and Rio Grande do Sul ( GRAZIA, VECCHIO & HILDEBRAND, 1982).

Adults dorsally green, with connexivum yellowish, and membrane of hemelytra infuscated. Medianbody length of females 14.0 mm (n = 10), and of males 12.0 mm (n = 10). Nymphs dark, with clear spots on dorsal surface of abdomen. Eggs brownish.
