Extract

Although Laricobius rubidus LeConte (1861, 1866) is not a common predator of the balsam woolly aphid, Adelges piceae (Ratz.), this paper is included in the series because of the close taxonomic similarities of L. rubidus in all stages to the recently introduced L. erichsonii Rosenh. In the past there has been confusion in the literature because the majority of records of rubidus have been erroneously attributed to erichsonii. These records have been discussed in detail in a paper on L. erichsonii, a species which has been introduced into North America as part of a biological control program against A. piceae (Clark and Brown, 1958).
