The bioactivity of six acqueous extracts 10% and 30% (P/V), containing terpenoids from Melia azedarach and Trichilia glauca (Meliaceae) in their chemical constitution, was evaluated against the pest Meloidogyne incognita (Nematoda, Meloidogynidae). Results show that the natural products assayed had a good nematicidal activity, because they had moderate lethal effects (mortality: 23-46.2%, depending upon treatment). These data show that the interesting properties of both Meliaceae could be used in orchard nematode management, in replacement of synthetic nematicides.

Key words: botanical pesticides , Melia azedarach , Trichilia glauca, Meloidogyne incognita.
