Southern green stink bugs (Hemiptera: Pentatomidae) as vectors of pathogens affecting cotton bolls - a brief review.

摘要

The southern green stink bug, Nezara viridula L., is a member of the stink bug complex that has become more economically important in cotton, Gossypium hirsutum L., production in recent years. A disease of cotton bolls, identified as South Carolina boll rot, seemed coincidental to the increase in abundance of stink bugs. The relationship between the occurrence of the cotton disease and the southern green stink bug is discussed here. This review documents: the identification and description of the disease; potential causal agents and insect vectors; conclusive identification of Pantoea agglomerans (Ewing and Fife) Gavini et al. as the causative agent of the disease; establishment of southern green stink bug as a model insect based on ingestion, retention, and transmission of the disease to cotton bolls; determination of vulnerability of bolls of different ages to disease; and, transmission of other disease agents by southern green stink bugs. Future research needs also are discussed.
