Ovipositional Preference of Rhynchophorus ferrugineus (Olivier) in Palm Species in Goa

Red palm weevil (RPW) Rhynchophorus ferrugineus (Olivier) (Coleoptera: Curculionidae) is devastating pest in commercial and ornamental palms. The study was conducted to find out ovipositional preference of R. ferrugineus in seven palm species. Result revealed that the fish tail palm (Caryota cumingii Lodd.) is highly preferred host for oviposition by R. ferrugineus followed by coconut (Cocos nucifera L). Toddy palm (Borassus flabellifer L.) was found to be least preferred by R. ferrugineus for oviposition. The ornamental palm, cane palm Dypsis lutescens (H. Wendl.) Beentje and J. Dransf is found as new preferred host for oviposition in free choice test.
