Abstract

Macrocentrus ancylivorus Rohwer overwintered in larvàe of the strawberry leaf roller, Ancylis comptana fragariae (Walsh & Riley), at the rate of from 544 to 7,623 per acre of strawberry field. Not more than 300 per acre of peach orchard, could be expected to overwinter in larvae of the Oriental fruit moth, Grapholitha molesta (Busck). About half of the larvae of M. ancylivorus in leaf rollers did not survive the winter.
