Abstract
The red palm weevil, Rhynchophorus ferrugineus (Oliver) (Coleopter: Curculionidae), is one of the most threatening and most important pests that infect date palms in Egypt. Many strategies have been employed to control this pest, among them, the employment of botanical extracts. The present study aimed to evaluate the insecticidal and antifeedant activity of Calotropis procera latex and foliar extracts against the 3rd and 5th instar larvae of R. ferrugineus. Results showed high insecticidal activity against both larval instars, however, the latex extract was more toxic than the leaves extract. Results also showed that both leaves and latex extracts have a high antifeedant index which was confirmed by the decreased mean larval weight. Finally, we can conclude that C. procera either used as leaves extract or latex extract represents an excellent alternative for conventional management procedures. More studies are considered on the effect of this plant on the different biological and biochemical parameters.
