Stink Bugs in a Cotton/Soybean Ecosystem: Impact on Quality and Yield

C. S. Bundy, R. M. McPherson and G. A. Herzog


Stink bug numbers were very low in south Georgia in 1996. N. viridula was most common followed by A. hilare, and E. servus, respectively. Pentatomids numbers were much higher in 1997. N. viridula was most common followed by E. servus, and A. hilare, respectively. Stink bugs were significantly more abundant in soybeans than cotton for both years. Seasonally, the Group VII soybean had more stink bugs than the Group V, and there were no differences in abundance between Bt and non-Bt cotton. The apparent preference of stink bugs for soybean suggests that this plant might be used as a trap crop for cotton. Analysis of stink bug-induced boll damage resulted in a 3-way interaction with variety, size, and date.
