SUMMARY:

The culture of corn and beans stand out as the most produced and exported grains in Brazil, playing both social and economic importance, present in human and animal food due to its rich nutritional value. With the population increase there was an increase in demand, highlighting the importance of grain storage, measures are needed to minimize losses during the storage period by pests and diseases that may reduce its quality and commercial value. Thus, the present study aimed to evaluate the bioactivity of clove essential oil and its mode of action in the management of stored grain pests. The research was carried out at the Alternative Pest Control Laboratory-LECAP, at the Insect Physiology Laboratory- UFRPE and at the Chemical Ecology Research Laboratory -UFAL, Campus Maceió/AL. Through chromatography, eugenol was identified as the major compound of clove oil, both the essential oil and its major compound had contact, fumigation and repellency effects on Sitophilus zeamais and Callosobruchus maculatus at different lethal concentrations. In addition to the major compound at different lethal concentrations, they promoted changes in the nutritional parameters of S. zeamais. These observations are timely to investigate the potential effects that essential oils can have on stored grain pests.
