PHENOLOGY OF THE HOMOPTERAN COMPLEX ON ORNAMENTAL HONEYLOCUST IN OHIO, WITH NOTES ON HOST IMPACT1
Phenology and relative abundance of the homopteran complex, including Macropsis fumipennis (Gillete and Baker), Stragania alabamensis (Baker), Empoasca fabae (Harris), Erythroneura clavata DeLong (Cicadellidae), and Micrutalis calva (Say) (Membracidae), were monitored on ornamental honeylocust, Gleditsia triacanthos L., near Wooster, Ohio. M. fumipennis, the most abundant species, completed its life cycle by late July. S. alabamensis was present from just after budbreak until frost, with collection data suggesting it is bivoltine. E. fabae and E. clavata adults were present from mid-June to early October. M. calva nymphs emerged in the spring and adults disappeared by mid-July, returning to honeylocust in early September. A second generation may develop on alternate hosts in summer. Observed foliar injury is attributed to the sympatric honeylocust plant bug, Diaphnocoris chlorionis (Say) (Hemiptera: Miridae), and not the homopterans reported here.
