Abstract

Various extracts of the medicinal plant Embelia ribes were tested for their insecticidal activity against eggs and larvae of Musca domestica, and adults of Rhyzopertha dominica and Tribolium castaneum. Powdered berries (at 15% concentration) and their ethyl acetate extracts (at 30% concentration) reduced the percentage pupation of M. domestica when added to the larval rearing medium. The ethyl acetate extract and a crystalline fraction (both at 4% concentration) derived from it produced 90 and 100% mortality, respectively, in 48-h-old larvae. The ethyl acetate extract (at 0.1%) also produced 76 and 67.6% mortality in T. castaneum and R. dominica, respectively, in wheat after 14 days exposure. The crystalline fraction, which resembled embelin, exhibited levels of toxicity comparable to embelin in all 3 species. Extracts obtained with other solvents produced lower levels of toxicity.
