Resumo: | The objective of this study was to test repellent substances for honey bees, Apis mellifera, for basil, Ocimum sellowii, and to study the most frequent insects in this crop as well as its behaviors. The frequency of honey bees did not decrease with the application of n.octyl.acetate, citronellal and 2.heptanone, used as repellents, in the concentrations 2.5, 5.0, 7.5 and 10.0% diluted in water. However, when the products (20%) were diluted in water (75%) and glycerine (5%) were effective in repelling those bees of the basil flowers for a period of 20 minutes. The flower lasted, on average, 30 h from the bud phase until the flower withered. The flowers number opened by inflorescence was, on average, 5.65 flowers, and the inflorescence presented, on average, 160 flowers-buds. The basil was visited mainly for the honey bee (98.0%), followed by Augochloropsis electra bee - Halictidae (2.0%) and visits sporadics of Diptera and Lepidoptera, collected only nectar. The honey bee frequency increased during the day to 14:00, decreasing soon after, accompanying the curve of the temperature sets registered in the experiment days.
