Pullus impexus (Muls.) is one of many species of predators that have been introduced into Eastern Canada since 1933 as part of a biological control program against the balsam woolly aphid, Adelges piceae (Ratz.) Delucchi (1954) has published many details of the systematics, biology, and natural control of this species in Europe where he found it to be associated with all A. piceae infestations. According to Pschorn-Walcher and Zwölfer (1960), it is one of a group of predators that are usually associated with lower population densities of A. piceae and other related adelgids, rhan are Aphidoletes thompsoni Möhn and Laricobius erichsonii Rosen. Because it is common on adelgid infestations in Europe and because it can easily be reared en masse, large numbers have been released in North America. The purpose of the present paper is to bring together available information on releases, life-history and natural control, and control value of this species, obtained from studies carried out over the past nine years in New Brunswick.

Woolly Aphid

Dried extracts of woolly aphid were treated with n-butanol, then by chromatography on DEAESephadex A50 and finally by filtration on Sephadex G150 to yield a substantially homogeneous protein catalysing the conversion of the aglucone of protoaphin into xanthoaphin. Traces of lowmolecular- weight contaminants were removed by chromatography on Sephadex G 100. The enzyme, which has a molecular weight of 120000�2000 and a high content of p-structure, was inhibited by naphthoresorcinol. Its glycoprotein nature was indicated by amino acid analysis.

And Control

Several species of native syrphids have been found to prey upon the introduced balsam woolly aphid, Adelges piceae (Ratz.), in New Brunswick and three of these, Syrphus torvus O. S., Metasyrphus lapponicus (Zett.), and Neocnemodon coxalis (Curr.), are sometimes very common. As part of a long-term study of the biological control of the balsam woolly aphid by native and introduced predators, the life histories, natural control, population fluctuations and control value of these native syrphids have been investigated.
