Extract

Neoleucopis pinicola Mall. is a common predator on the pine bark aphid, Pineus strobi (Htg.) in New Brunswick. The host adelgid occurs throughout most of the United States and southern Canada on white pine, Pinus strobus, L., Scots pine, Pinus sylvestris L., and Austrian pine, Pinus nigra Arnold (Craighead, 1950). It is also an occasional predator on the balsam woolly aphid, Adelges piceae (Ratz.) (Brown and Clark, 1956b). No reference to N. pinicola was found in the literature other than Malloch's (1921) description.
