Relationship between A. glycines and natural enemies (averaged across seven taxa: O. insidiosus, Nabis spp., exotic coccinellids, native coccinellids, Chrysoperla spp., syrphids, and Araneae) in 2006–2008. Weekly aphid and natural enemy abundance data were transformed ln(x+1). Lines associated with the same letters do not have significantly different slopes (P > 0.05). Equations for slopes follow; 2006: y=0.0224x+0.3406; 2007: y=0.0028x+0.3685; and 2008: y=−0.0084x+0.2592.
