Urban Shade Trees and Carpenter Ants    (View PDF)

H.G. Fowler and M.D. Parrish

Abstract: Carpenter ants nests were found in 75% of the 306 urban shade trees sampled in central New Jersey during 1 981-1 982. Silver maple demonstrates the greatest nesting usage by carpenter ants, while white pine is the least used (apparently avoided). There is an overall pattern of nesting activity associated with visible tree damage. Nesting activity increases the risk of wind breakage, and may open invasion channels for secondary tree pests and pathogens. Additionally, carpenter ant colonies have an indirect effect on shade trees through their protection of honey-dew producing insects.
