Conteúdo: | The bean weevil, Acanthoscelides obtectus Say, causes severe post-harvest losses in the common bean,Phaseolus vulgaris L. The control of these insects is either non-existent or relies heavily on the use of con-ventional insecticides, which increase the risks associated with pest resistance, hazards to human healthand environmental contamination. Protecting grains with alternative chemical control options that allevi-ate the concerns outlined above are urgently needed, and essential oils of plants have been presented as asuitable alternative to fill this void. Therefore, this investigation evaluated the non-fumigant applicationsof clove, Syzygium aromaticum L., and cinnamon, Cinnamomum zeylanicum L., essential oils adequatelycontrol A. obtectus on common beans. The oils were tested for insecticidal (lethal toxicities, disturbanceson reproductive traits and persistence of action) and repellent activities. Both oil types showed similartoxicity (clove LD = 43.6 L/kg beans; cinnamon LD50= 46.8 L/kg beans), steadily decreased the growthrate of A. obtectus in a dose-dependent manner, and similarly lost their insecticidal activity over the time.Additionally, the clove oil delayed bean weevil emergence, whereas cinnamon oil repelled the bean wee-vil. These results indicate clove and cinnamon essential oils as desirable tools for protecting stored beansagainst A. obtectus in small storage facilities, promoting environmentally friendly pest control strategies.
