Abstract

Frightening has been successfully used to control many animal pests in some cases in an effort to reduce or replace pesticide use. Despite evidence that some mosquito females can response to dead predator and physical objects, there have been no studies regarding the impacts of predatory intimidation on mosquito vectors. This thesis examined the effects of artificial predators on the oviposition behavior of dengue vectors. Using equal oviposition choice bioassays involving natural predators, it was found that potential breeding sites containing images of these predators were repellent or attractive to Ae. aegypti females. These results altogether indicate that artificial predation influences the oviposition behavior of Ae. aegypti and this knowledge could be explored to develop novel, inexpensive and environmentally-friendly dengue control strategies.
