Field research on control of vegetable insects in eastern New York- 1974
Straub, R.; Huth, P.
Insect populations in the Orange and Ulster County region of eastern New York were adequate, in most instances, for good evaluations of insecticide activity. In the Orange County muck area, populations of the onion maggot, Hylemya antiqua (Meigen), and aphids, primarily the green peach aphid Myzus persicae (Sulzer) and the potato aphid Macrosiphum euphorbiae (Thomas), were quite high. Cabbage looper, Trichoplusia ni (Hubner), pressure was light until later August at which time populations increased to moderate numbers.
