For the past 3 seasons, a green fruitworm, <i>Lithophane georgii</i> Grt., has injured apples in the Okanagan Valley of British Columbia. Larvae feed on leaves, will attack fruit early in the season causing deep russeted pits similar to those caused by the fruit-tree leafroller, <i>Archips argyrospilus</i> (Walker). Larvae were active from late April to early June. Pupation took place in the soil, and adults emerged in October. The insect apparently overwinters as an adult and deposits eggs early in the spring, although eggs of this species have not been found in the field. Although larvae of <i>L. georgii</i> are capable of injuring apples, observations in 1970 and 1971 indicate the numbers are so low that the species cannot be considered a major pest.References
