Extract

Bembecia marginata (Harr.), commonly called the raspberry crown borer, raspberry root borer, or blackberry crown borer, is native to North America. Harris (1839) first recorded it from New Hampshire as Trochilium marginata Harr. Edwards (1881) first named it Bembecia marginata (Harr.). Beutenmüller (1901) summarized its many synonyms.

With increased acreage of cultivated cane fruits in Canada this insect has become a serious agricultural pest. It does not occur in outbreaks, but builds up slowly over a period of years and gradually reduces the vigour and yield of plantings. Damage is caused by the larvae which undermine the new buds at the base of the plants in the spring and girdle the new canes during the summer. Especially affected are young plantings which produce only a few canes at first.
