Abstract
Adult apple maggots, Rhagoletis pomonella (Walsh), were relatively free from attacks by predators in southern Ontario. The main reason for this was the flies’ alert avoidance of approaching objects. In addition to this protection from predators, the flies appeared to be avoided by hunting spiders. Adults of the cherry fruit fly, Rhagoletis cinqulata (Loew), were equally alert and apparently free from predation while they were in apple trees.
