          Abstract

          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.

          O objetivo do experimento foi estudar a polinização em manjericão (Ocimum sellowii), a fim de verificar sua atratividade para as abelhas Apis mellifera, os insetos mais freqüentes, bem como seus comportamentos e testar substâncias repelentes para as abelhas A. mellifera. A flor durou, em média, 30 horas, desde sua abertura até o murchamento. O número de flores abertas por inflorescência foi, em média, 5,65 flores, sendo que a inflorescência possuía, em média, 160 botões florais. O manjericão foi visitado quase que exclusivamente pela abelha A. mellifera africanizada (98,0%), seguida pela abelha Augochloropsis electra-Halictidae (2,0%) e visitas esporádicas de dípteros e lepidópteros, sendo que todos coletavam apenas néctar. A freqüência da abelha africanizada aumentou no decorrer do dia até às 14 horas, diminuindo em seguida, acompanhando a curva da temperatura ambiente registrada nos dias do experimento. As abelhas africanizadas demoraram de 1 a 3 segundos em cada flor. A freqüência das abelhas africanizadas não diminuiu com a aplicação dos produtos n.octyl.acetato, citronellal e 2.heptanona, usados como repelentes, nas concentrações 2,5, 5,0, 7,5 e 10,0%, diluídos apenas em água. Entretanto, quando os produtos (20%) foram diluídos em água (75%) e glicerina (5%), foram efetivos em repelir essas abelhas das flores de manjericão, por um período de 20 minutos.
