Guess the Pest Week #11
Answer is….. Kudzu Bug
The kudzu bug, also called the bean plataspid, lablab bug, and globular stink bug is an invasive species introduced from Asia. It that was first discovered in Georgia in 2009 and has since been detected throughout much of the southeastern US. In 2013, the kudzu bug was detected in Sussex County Delaware. Kudzu bug adults and nymphs are a pest of soybean, using their piercing sucking mouthparts to feed on plant sap of soybean stems and leaf petioles. In Georgia and South Carolina, kudzu bug feeding injury reduced yield in 16 of 19 trials with an average yield loss of 18%, ranging from 0-47%. Currently, in Delaware we have not had a single soybean field with a yield limiting infestation of kudzu bugs. However, if this invasive pest were to become a problem for us, scouting methods, and thresholds have been developed in the South and there are many insecticides that can provide effective control.
I am currently surveying soybean fields and a couple kudzu bug patches throughout the state for kudzu bugs. Please contact me if you find a field infested with kudzu bugs (bcissel@udel.edu).
