Abstract

Insecticidal potential of eleven species of Aglaia (Meliaceae) was evaluated in the laboratory against the cabbage cluster caterpillar, Crocidolomia binotalis. The feeding treatment of second-instar larvae C. binotalis for 48 hours with ethanol twig extract of A. odorata at 0.5% caused 98.7% larval mortality; leaf and twig extracts of A. elaeagnoidea caused 17.3% and 6.7% mortality, respectively; twig extracts of A. argentea, A. formosana, and A. latifolia caused only 1.3% mortality each; whereas extracts of the other six Aglaia species were inactive (0% mortality). Further tests with A. odorata showed that twigs gave the most active extract compared to other plant parts (leaves, flowers, and roots), and air-drying of plant materials for 2 weeks markedly decreased the activity of the derived extracts. The active extracts also delayed the development of surviving larvae in similar degree to the level of their lethal effect. LC50 of ethyl acetate fraction of A. odorata twig extract and its main active compound, rocaglamide, against C. binotalis larvae were 310.2 and 31.4 ppm, respectively. This active compound was about 8.7 times less potent than azadirachtin (LC50 3.6 ppm).

Abstract

The objective of this study was to evaluate the insecticidal activity of bark extracts of 35 plant species belonging to four families (Clusiaceae, Lecythidaceae Meliaceae, and Sapindaceae) against the cabbage head caterpillar Crocidolomia pavonana. Extraction of the test plant materials were performed with maceration method using ethanol and methanol continued by counter-current distribution separation in ethylacetate and water. Bark extract preparation of each plant species was tested against C. pavonana larvae by leaf-feeding method at concentration of 0.25% and 0.5%. Second-instar C. pavonana larvae were fed extract-treated broccoli leaves for 48 hours, then were presented with untreated leaves until the surviving larvae reached the fourth-instar larvae. The number of dead larvae was recorded. The phytochemical test of bark extract of Calophyllum soulattri was done by qualitative method. The results showed that the bark extracts of C. soulattri (Clusiaceae), Barringtonia sarcostachys (Lecythidaceae), and Aglaia tomentosa (Meliaceae) exhibited good insecticidal activity. Methanol extract of C. soulattri barks possessed strong insecticidal activity against C. pavonana larvae with LC95 of 0.21%. This extract showed positive response in alkaloid and triterpenoid qualitative tests. Further studies are needed to identify insecticidal compounds in those active extracts.
