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.
