Control of Hyadaphis tataricae (Homoptera: Aphididae) on honeysuckle including observations on host plant resistance

Hyadaphis tataricae causes witches-brooming to the growing tips of Zabelii and other large bush-type honeysuckles in the north central states. Insecticide tests show that acephate (Orthene), dimethoate (Cygon), or oxydemeton-methyl (Metasystox-R) sprayed monthly in June and July will reduce witches-brooming. Malathion was not effective in reducing damage. Host plant resistance observations indicate that Lonicera x notha . L. x muendeniensis , L. x amoena "Alba", L. x xylosteoides , and L. tatarica "Arnold Red" are H. tataricae resistant. These large bush-type honeysuckles would appear to be good replacements for Zabelii and other susceptible honeysuckles in ornamental plantings.
