Monoterpenos limoneno e
cineol tem acao inseticida para pragas de graos armazenados, a acao de toxicidade se da atraves das vias respiratorias (fumigacao), da cuticula (contato) e da ingestao (graos tratados) (Restello et al., 2009).
Esto es debido principalmente a los componentes del aceite esencial (
cineol y alcanfor) que afectan negativamente el desarrollo y eclosion de huevos de parasitos.
