Abstract | ||
The different cultivars of date and decorative palms are attacked by a variety of insect species, most notably the red palm weevil (RPW) Rhynchophorus ferrugineus (Olivier) (Coleoptera: Curculionidae), which has become a global palm destroyer pest. Adult R. ferrugineus behavioral responses to different concentrations of ethyl acetate were assessed using a four-arm-choice olfactometer. A higher ethyl acetate concentration (1000 ng) resulted in higher attract, with significant differences found in response of virgin (F = 8.50; P 0.003) and mated female after 1 and 2 weeks of meeting (F = 11.73; P 0.0007 for 1 week and F = 5.75; P 0.01 for 2 weeks, respectively). A deeper knowledge of these attracted individuals may increase the efficacy of mass trapping in the control of adult red palm weevils. | ||
