Effect of palm cultivars on certain biological and life table atiributes of the red palm weevil, Rhynchophorus ferrugineus (Olivier) (Coleoptera: Curculionidae) [electronic resource].

Includes references.

The developmental time of immature stages. developmental rate, longevity, fecundity, and life table parameters of the red palm weevil (RPW), Rhynchophorus ferrugineus (OliVier) were investigated on ten cultivars from four groups of palms (soft date, semi-dry date, dry date and ornamental palms) under laboratory conditions. The data indicated that there was a significant variation in the developmental time of immature stages of R. ferrugineus when reared on the four groups. The highest developmental rate of R. ferrugineus was achieved when reared on Samany and Amri cultivars. In addition. there were significant differences between the ten palm cultivars .in larval stage. while there were no significant differences in an incubation period and ,pupal stage,on the tested palm cultivars.
