The corn aphis was very abundant on corn at times. It especially infested the tassels just before or at the time of expansion. I did not find it on other plants, but in 1911, Fullaway reported it also occurring on broom and Kafir corn. Three species.of ladybeetles were found feeding on the corn aphis, Harmonia a,rcuata , Coelophom inaequalis, and Anisoleninia 1nulsanti. The first mentioned was most abundant and very effective in reducing an infestation. The last mentioned was only occasionally seen. A syrphid fly was commonly seen also, its green larvae feeding on aphids .
