| Summary: | <p>Stink bugs (Hemiptera: Pentatomidae) are key pests of soybean, <i>Glycine max</i> (L.), in Mississippi. Historically, yield loss derived from direct feeding by stink bugs has been considered the greatest threat to producers. However, quality reductions resulting from seed infections caused by microorganisms including <i>Phomopsis longicolla</i> are also a concern. Experiments were conducted in 2010 and 2011 to determine if stink bugs are associated with the incidence of <i>P. longicolla</i> in Mississippi soybean production. Data from experiments suggest that stink bugs are capable of transporting <i>P. longicolla</i> between two points. Data further suggest stink bugs and <i>P. longicolla</i> have the potential to cause a yield loss of 20% when combined in soybean. Surveys of commercial fields in Mississippi determined that stink bug damaged seed was more likely to be infested with <i>P. longicolla</i> and other fungi compared to undamaged seed.</p> |
