The effect of essential oils of sweet fennel and pignut on mortality and learning in africanized honeybees (Apis mellifera L.) (Hymenoptera: Apidae)

Abstract: Efeito de Óleos Essenciais de Erva-Doce e Alfazema sobre a Mortalidade e Aprendizagem de AbelhasAfricanizadas (Apis mellifera L.) (Hymenoptera: Apidae) What is not known is whether these oils also infl uence honeybee behavior. Experiments using both harnessed and free-fl ying 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 cr… Show more

“…The use of lower concentrations of fennel essential oil is an important factor to be considered in management programs for insect pests, given that high de Oliveira et al Means followed by the same letter (within line) do not differ by overlapping confidence intervals (IC 95%). concentrations of this product may adversely affect beneficial insects such as bees (Abramson et al, 2007) and natural enemies such as Euborellia annulipes (Lucas) (Dermaptera: Anisolabididae) (Silva et al, 2009), as well as the physiological quality of fruit red mombin fruit (unpublished data). Although, the essential oil of fennel is more efficient than proagrim and essential oil orange, these two products can be considered important substances for the control of C. capitata.…”

“…Prospecting criteria may incorporate the investigation of EOs found to be active against other mites of veterinary importance as recently reviewed in (Flamini Phytochem Rev (2011) 10:227-244 239 2006; George et al 2008), such as the poultry red mite, Dermanyssus gallinae GhrabiGammar et al 2009), the ear mite Psoroptes cuniculi (Lans et al 2008), the sheep tick Ixodes ricinus (Garboui et al 2009), the cattle tick, Rhipicephalus (Boophilus) microplus (Jonsson and Piper 2007), etc. Besides, other promissory products to be tested against varroa are the ones that have already being described in other non-varroa related studies as innocuous against bees, such as the Lamiaceae, Hyptis suaveolens (Abramson et al 2007), Ocimum basilicum (Albo et al 2003) and Salvia sclarea (Ebert et al 2007). As a final comment, it is worth of notice that there have been some studies on varroa using volatile chemicals from bees (kairomones) to find the brood cells more suitable (Nazzi et al 2003;Dillier et al 2006).…”

“…The flying path from the hive to the feeder was very linear and without obstacles or barriers. In semi‐field experiments, three treatments (untreated sugar solution and sugar solution with diafenthiuron at 3 and 30 µg mL −1 ) were made, and bees were sequentially tested on the trial day starting from 7.30 a.m. On the trial day, 30 honey bees that had been feeding on the feeder were captured and labelled with green‐coloured fingernail polish20 and used as control. The bees were allowed to be in a flying cage (60 × 60 × 30 cm) for a period of 1 h. The bees were then released in the feeder site, and the number of released bees coming to the hive was counted.…”
