Article by Jack Bacheler, NCSU Extension Entomologist
David Orr (NCSU Entomology biocontrol specialist) and I sampled 25, 1-meter kudzu terminals in a kudzu patch on the Dorthea Dix property next to the NCSU Centennial Campus yesterday. For kudzu vines just now coming up well, it was startling to find an average of more than 4 egg masses per single 3-foot vine and more than 350 kudzu bugs per 20 sweeps! High levels of overwintering kudzu bugs during the winter months at several locations also indicate that we may be due for a significant jump in homeowner and soybean producer headaches in 2013. The purpose of this and other sampling conducted by Kathy Kidd of the NCDA&SC and Dominic Reisig is to determine the variety and abundance of native parasitiods (thought to be very limited) on kudzu bug egg masses in NC (and throughout the Southeast) in preparation for the possible release of an imported egg parasitoid from Asia in 2014.
