This research investigated the feeding behavior of the soybean aphid, Aphis glycines, on thiamethoxam seed treatment on soybean, Glycines max. In this study, soybeans were treated with thiamethoxam (Cruiser 5FS) and grown under greenhouse conditions along with the untreated control. Electronic Penetration Graphs (EPG) were used to document A. glycines feeding. An individual aphid was placed on selected at V2 and V4 vegetative growth stage (second and fourth trifoliate) soybean plants and allowed to feed for 9 h. Results will be presented at the North Central Branch meeting.
