Control of Honeylocust Insects, Aurora, Co, 1984

Honeylocust trees, 8-12 ft in height, at the City of Aurora Nursery were monitored for the occurrence of the second generation of the honeylocust pod gall midge. Extremely heavy oviposition was observed May 30 and an insecticide trial was initiated on that date. Single tree plots were arranged in a RCB design with 3 replications. Treatments were applied with a hand-operated compressed air sprayer until point of run-off. Evaluations were made Jun 13. Honeylocust pod gall midge infestations were estimated by counting the number of new galls on 15 terminals/tree. Plant bugs and leafhoppers were counted by shaking 2 lower branches/tree over a food tray.
