Hyadaphis tataricae is an aphid pest of honeysuckle relatively new to the Great Lakes and midwestern regions of North America. Feeding results in severly deformed terminals (witches' brooms). Studies were conducted on natural, chemical, and cultural control. Foliar-applied systemic insecticides provided excellent knock-down and 3-4 weeks of residual control. Although diazinon also provided good knock-down, its residual activity was shorter. Malathion provided suppression but did not protect plants from injury. A tree and shrub soap wash did not provide control. Oxydemeton methyl provided best results of soil-applied systemics. Of 385 aphidophagous predators collected, 85% were syrphid larvae. The remainder were Coccinellidae and Chrysopidae. About 140,000 aphids were examined microscop- ically without visual evidence of insect pathogens and with only one mummified (parasitized) individual. Dormant pruning of previously broomed terminals resulted in increased vegetative growth of the plants and larger early season aphid populations. There was no visible difference in pruned vs. unpruned plants at the end of the growing season.
