Abstract

llyadaphis 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 (Cygan), 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 ).;ylosteoides, and L. tatarica 'Arnold Red' are ll. tataricae resistant. These large bush-type honeysuckles would appear to be good replacements for Zabelii and other susceptible honeysuckles in ornamental plantings.
