Evaluation of Jatropha curcas and Annona muricata Seed Crude Extracts Against Sitophilus zeamais Infesting Stored Rice

Asmanizar, A. Djamin and A.B. Idris
A laboratory study to test the bioactivity of Jatropha curcas and Annona muricata seed crude extract against Sitophilus zeamais (Coleoptera: Curculionidae) was conducted by using dipping and surface protectant methods. Both J. curcas and A. muricata seed crude extract had contact and stomach poison against S. zeamais. By dipping method, the weevil mortality were 90 and 70%, respectively at concentration 20% (v/v), whilst by surface protectant method, the weevil mortality was 100% at 0.4% (v/w) concentration for both crude extracts. The J. curcas and A. muricata seed crude extracts applied on rice grain (surface protectant method) can reduced the F1 progeny production, weight loss and rice grain damaged. This result suggests that the J. curcas and A. muricata seed crude extracts may have the potential to be used in controlling S. zeamais infesting stored rice grain.
