Resumo
Recent studies, proposed to obtain active compounds against termites (Heterotermes tenuis Hagen, as a model) have showed that attention could be driven to the limonoids, because they present high insecticidal activity against several insects. In this work, the limonoids nimbolin-A, 1,2- hydroxyamoorastatone, mexicanolide, cedrelone and 1,2-dihydrocedrelone were tested in order to verify their potential for the control of H. tenuis workers. The results indicated that cedrelone and 1,2-dihydrocedrelone are the limonoids with higher antifeeding activity, followed by 12-hydroxyamoorastatone, mexicanolide and nimbolin-A.
