- Title
Family Effects on Antipredator Behavior in the Field Cricket, Gryllus Integer.

- Abstract
Most animals have antipredator mechanisms. These may include a variety of behaviors. One such behavior is 'freezing', i.e. becoming immobile in response to a predator. This paper is focused on freezing behavior in a species of field cricket, Gryllus integer. We studied this behavior in both nymphs and adults, and looked for family effects, as well as the effects of sex. Our research shows that there are no family effects in nymphs, but there are family effects in adults. No sex differences occur between the sexes at either stage of development. Because all of the crickets were reared under identical conditions in the laboratory, such family effects are likely due to genetic effects, maternal effects, or both.
