Antifeedant and insecticidal activities of some Philippine plant species

Issue Date

10-2004

Abstract

Organic extracts from different parts of plants belonging to 15 Philippine species were screened for antifeedant activity adapting the dual choice antifeedant assays, and for other insecticidal activities through contact toxicity, using the Mexican bean beetle (Epilachna varivestis) as test insect. Materials with high antifeedant activity were extracts form Derris philippinensis, Coleus amboinicus, Mikania cordata, Tithonia diversifolia, Aristolochia elegans and Agave cantala, while those with lower antifeedant activity were from Tinospora rumphii, Lantana Camara, Dipterocarpus warburgii, Dioscorea hispida and Ceasalphinia pulcherrima. Only D. philippinensis extract showed high insecticidal activity. Those with limited insecticidal action were extracts from C. amboinicus, L. camara, M. cordata, T. diversifolia, and A. elegans, while those that did not show any activity on E. varivestis were from Piper betle, Donax cannaeformis, Lee aculeata and Entada phaseoloides.
