The mosquito feeding and ovipositional repellency of the major monoterpenoid present in the volatile oil of Hemizonia fitchii (Asteraceae), i.e., 1,8-cineole, was investigated. Although 1,8-cineole did not exhibit any significant mosquito larvicidal activity, it was moderately effective as a feeding repellent and highly effective as an ovipositional repellent against adult Aedes aegypti (yellow fever mosquito). The ovipositional repellency of 1,8-cineole, coupled with the presence of several Hemizonia chromenes previously shown to possess mosquito larvicidal activity, may therefore account in large part for the observed suppression of local mosquito populations which was associated with H. fitchii plants in northern California. © 1987 Plenum Publishing Corporation.
