![]() ![]() ![]() In contrast, mantids are generally ambush predators, waiting for prey to enter their attack range. The zebra spider is an active hunter, locating prey visually (with an extensive visual field attained by antero-medially positioned simple eyes). melanogaster derived from a wild-caught population. Here, we document the influence of two predators, the zebra jumping spider ( Salticus scenicus) and juvenile Chinese praying mantids ( Tenodera sinensis) on the behavioral repertoire of individual D. Despite this literature, the anti-predatory behavioral repertoire of adult D. melanogaster per se, the role of parasites in influencing larval and adult behaviors has been extensively studied. For example, Worthen (1989) studied the effects of predation by rove beetles (staphylinids) on the coexistence of three mushroom-feeding Drosophila species, and Escalante & Benado (1990) showed that ant predators regulate population densities of wild D. Previous work has examined the effects of natural enemies on population and community structures of a few Drosophila species. melanogaster’s natural history, ecology and behavior, including habitat, food resources, and natural enemies (but see ). melanogaster because, although the species is one of the most well-studied model organisms in genetics, there is a relative paucity of information regarding D. Here we examine variation within and between individuals in the behavioral repertoire of the fruit fly, Drosophila melanogaster, in response to two predator species that, among other attributes, differ in hunting modes. ) explicitly considered the role of predator hunting-mode (e.g. Despite the importance of hunting mode in determining behavioral responses in prey, only recently have studies that describe the effects of predators on prey traits (e.g. Predator hunting-modes, i.e., the set of behaviors that predators employ to pursue and capture their prey, have been shown to induce distinct prey responses that can have dramatic implications on the productivity of ecological communities. Predation is a ubiquitous selective force that shapes the evolution and maintenance of defensive traits in prey populations.

We documented three particularly interesting behaviors: abdominal lifting, stopping, and retreat-which were performed at higher frequency by D. Here we observe and describe the influence of two predators that differ in their mode of hunting: zebra jumping spiders, Salticus scenicus (active hunters) and Chinese praying mantids, Tenodera sinensis (ambush predators) on the behavioral repertoire of Drosophila melanogaster. melanogaster, nor the anti-predatory behaviors they may employ to escape and avoid their enemies have been documented. In particular, neither the natural predators faced by wild populations of D. However, relatively little is known about the natural history of D. The fruit fly, Drosophila melanogaster, has proven to be an excellent model organism for genetic, genomic and neurobiological studies. ![]()
