Abstract

The life cycles of two pentatomid species, Ramosiana insignis and Vulsirea violacea, are reported for first time. We include descriptions and illustrations of all instars, as well as the host plant and behavior. females of these two species care for their eggs and first-instar nymphs, and both species have the same host, Schoepfia schreberi, although R. insignis feeds on flower buds, fruits, and vegetative structures, whereas V. violacea feeds only on fruit. Adults are present at the same time on the plant, and even though their life cycles are separated in time, it seems that there is competition between them. Parasitoids and predators are also reported.

Abstract

The species composition and abundance of stink bugs (Heteroptera: Pentatomidae) in corn, Zea mays L., was determined in this on-farm study in Georgia. Seven species of phytophagous stink bugs were found on corn with the predominant species being Nezara viridula (L.) and Euschistus servus (Say). All developmental stages of these two pests were found, indicating they were developing on the corn crop.
