Soybean aphid is a severe pest of soybean in the Midwestern and Great Lakes regions of North America. Aphids are highly mobile and isolated infestations may spread to both adjacent and distant regions over the course of a growing season. Since 2005, the North Central IPM Center, in collaboration with the Ontario Ministry of Agriculture, Food and Rural Affairs, has maintained a network of 47 suction traps to monitor aphid flights spanning the area where soybean aphid is of economic concern. Aphid capture data were examined relative to field counts, date, photoperiod, and weather. Geographic distribution of aphids was modeled through time and compared to relevant environmental cues. Applications of modeling aphid flight trajectory will be discussed.
