Resumo
The presence of Apis mellifera in places such as candy and soft drink factories, restaurants, and ice-cream shops has been a concern to many people. In the yellow passion-fruit crop, Apis mellifera is able to collect all anther pollen but has no active role in pollination. Honeybees also visit animal feeders with chopped sugar cane, preventing the cattle from eating. This work studied the effect of natural and synthetic substances as Apis mellifera repellents in vitro in the yellow passion-fruit crop and in confined beef cattle feeders. There was a repellent effect in vitro with the following substances in decreasing order: tobacco, rue, garlic, parsley, and century plant extracts; average effect was twenty-five minutes. For the yellow passion-fruit, garlic extracts and 2-heptanone were equally efficient with a two and a half hour repellent action. Garlic and citronella extracts were efficient in repelling Apis mellifera from confined beef cattle feeder for six hours. Garlic repellent action was higher than citronella.
