The keys to sustainable management of this pest include understanding linkages between the soybean aphid and other introduced and native species in a landscape context along with continued development of aphid-resistant varieties. The current distribution of this ladybird in the eastern. The preexisting community of aphid natural enemies has been highly effective in suppressing aphid populations in many situations, and classical biological control efforts have focused on the addition of parasitoids of Asian origin. An existing key to North American species of Coccinella is revised to include C. It was also established in various regions of North America (Wheeler and. KEY WORDS Insecta, Coccinella septempunctata, spectral sensitivity, vision Coccinella septempunctata (L.) is a European predator on several species of aphids and is now established in the eastern and central parts of North America (Schaeffer et al. Aphid-resistant soybean varieties were available to growers in 2010. coccinella from the teleomorphic fungus Orbilia. In response, important elements of the ecology of the soybean aphid in North America have been elucidated, with economic thresholds, sampling plans, and chemical control recommendations widely adopted. The decline of the North American native lady beetle, Coccinella. Native to Asia, this invasive species was first discovered in North America in July 2000 and has rapidly spread throughout the northcentral United States, much of southeastern Canada, and the northeastern United States.
