Adelges Piceae

Neoleucopis pinicolaMall. 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 sylvestrisL., and Austrian pine,Pinus nigraArnold (Craighead, 1950). It is also an occasional predator on the balsam woolly aphid,Adelges piceae(Ratz.) (Brown and Clark, 1956b). No reference toN. pinicolawas found in the literature other than Malloch's (1921) description.

Adelges Piceae

Early in the present century the balsam woolly aphid, Adelges piceae (Ratz.), was introduced accidentally into North America. The history of its development and spread in the United States and Canada has been described by Balch (1952). At the present time, the adelgid occurs in eastern Canada over approximately the southern half of New Brunswick with an extension of the range in the extreme northeastern part of the Province, throughout Nova Scotia and Prince Edward Island, and in some areas of the southwestern and southeastern parts of Newfoundland.

Over the past ten years a number of exotic predators have been introduced into New Brunswick and other parts of North America as part of a biological control program against the balsam woolly aphid, Adelges piceae (Ratz.). Several of these have become established and others show considerable promise. As introductions continue it becomes exceedingly important that field workers be able to distinguish rapidly all stages of introduced and native predators. Field identification characters for some species (Chamaemyiidae and Syrphidae) have been published in previous papers in this series (Brown and Clark, 1956, 1960; Clark and Brown, 1957) and have been found to be very useful.

Cremifania nigrocellulata Cz. is one of the complex of predators that attacks A. piceae (Ratz.) in Europe. After studies on its morphology, biology, and distribution were made by Delucchi and Pschorn-Walcher (1954), C. nigrocellulata was reared in Europe by the Commonwealth Institute of Biological Control and introduced into New Brunswick via the Entomology Research Institute for Biological Control, Belleville, Ontario.

William Diller Matthew was the eldest child of Dr. G. E. Matthew, of New Brunswick, an amateur geologist, who, by his great collections and excellent papers, added much to our knowledge of that part of Canada. Dr. Matthew was born on February 19,1871, in St. John, New Brunswick ; throughout his life he retained an interest in this town, visiting it yearly, except when abroad, and retaining his Canadian nationality during nearly forty years’ residence in the United States. Dr. Matthew was introduced to geological methods by his father, and sent at first to the small University of Halifax, whence in 1892 he proceeded to Columbia University as a graduate-student, there studying geology, mineralogy and metallurgy. He graduated Ph.D. in 1895. In that year he was selected by Professor H. F. Osborn, whose classes he had attended, as assistant in the department of Vertebrate Palaeontology in the American Museum of Natural History, New York. In this department he worked for thirty-two years, finally becoming Curator-in-chief of the division of geology, mineralogy and palaeontology.
