Última Efficiency of n-octyl-acetate, 2-heptanone and citronellal in repelling bees from basil (Ocimum sellowii - Labiatae) BABT Malerbo-Souza,Darclet Teresinha; Nogueira-Couto,Regina Helena. 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,...

The mosquito-repelling devices Anti-Pic®, Mosquito Repeller® DX-600 and Bye-Bye Mosquito® were evaluated in boxes for experimentation by exposing human hands to Aedes albopictus (Skuse) adults. Two sets of tests were performed based on 15 min. expositions. In the first set both hands were introduced in the box, one of them holding the device on. In the second set only one hand was introduced each time, holdind the device on or off. The devices failed to show efficiency in both evaluations. A seemingly 30.3% repellency due to Anti-Pic® in the first set of experiments was not confirmed in the second set. It was discussed the value of such devices for dengue prevention.

Ano: 2001 URL: http://www.scielo.br/scielo.php?script=sci_arttext&pid=S1519-566X2001000300030 The effect of essential oils of sweet fennel and pignut on mortality and learning in africanized honeybees (Apis mellifera L.) (Hymenoptera: Apidae) Neotropical Entomology Abramson,Charles I.; Wanderley,Paulo A.; Wanderley,Maria J.A.; Silva,José C.R.; Michaluk,Lynnette M.. It was recently discovered that exposure to small concentrations of the essential oils of sweet fennel (Foeniculum vulgare Mill) or pignut [Hyptis suaveolens (L.) Poit] can be used to control aphids. What is not known is whether these oils also influence honeybee behavior. Experiments using both harnessed and free-flying foragers at concentrations used to control aphids showed that bees readily associated the odors with a reward, discriminated between them, and were not repelled. Honeybees, however, would not consume the oils when mixed with sucrose to create an unconditioned stimulus. An experiment in which harnessed bees consumed various concentrations showed that concentrations greater than 50% were detrimental. The experiments reported here provide...
