Winged aphids were collected on black sticky traps in bean fields at Lansing, Ithaca, and Canastota, N. Y. The proportional aphid populations collected on individual traps were similar regardless of trap locations within fields. The proportional aphid populations of 2 plots at Lansing and 3 plots at Ithaca were similar. The proportional aphid population at Canastota differed somewhat from that from the Lansing and Ithaca populations, but all identified species collected at Canastota were found also in the other 2 locations. The corn leaf aphid, Rhopalosiphum maidis (Fitch); the turnip aphid, Hyadaphis pseudobrassicae (Davis); the yellow clover aphid, Therioaphis trifolii (Monell); and Brachycolus atriplicis (L.) were the 4 commonest species in all 3 locations. All species collected in 1964 were collected also in 1965 but in somewhat different proportions. R. maidis was the commonest aphid in both years. The seasonal distribution of individual species was similar in both years.
