8 Soybean Generally feeds on Stems As Apposed to Pods Corn NO Thanks! Life History (GA) Overwinters as an adult Overwintered adults become active Feed on many plants, seek reproductive hosts e.g. kudzu and Soybean. Usually infest kudzu 1 st but in 2012 infested early planted soybean. Soybean becomes attractive at about V 3 Overwintered adults lay eggs for many weeks. Life History Cont. (GA) 1 st Gen (F1) egg to adult development about 6 8 wks. Spring 6 wks. June 1 st Gen Adults present Mid June F1 Adults disperse from kudzu to soybean for several weeks while overwintered adults still laying eggs. During this dispersal re infestation can/will occur After dispersal a SINGLE application is very effective. 8

9 Treatment Threshold Scouting use a 15 sweep net 1 immature kudzu bug per sweep Don t spray too early, if well timed a single application will preserve soybean yield. Only treat before immature appears if Adult numbers are very high and Plants are under significant stress from another factor. e.g. drought. Yield Impact Yield data has been collected from 19 replicated trials in Georgia and South Carolina. Yield was numerically reduced in unprotected plots in 16 of 19 trials. An average yield loss of 18 percent and a range from 0 47 percent. Kudzu bugs feed on plant sap and can be considered a stress inducing pest Insecticide Efficacy: The table below summarizes insecticide efficacy data from trials conducted in 2010 and 2011 in Georgia and South Carolina (Dr. Jeremy Greene, Clemson University Entomologist).
