Desarrollo de un producto a base de neem (Azadirachta indica) para el control de Varroa destructor.
Provedor de dados: 32
Autores: González Gómez, Rebeca.
Se estudió el efecto del extracto oleoso de neem (A. indica) en el control de V. destructor. La investigación estuvo encaminada a explorar los efectos que causa el neem tanto a V. destructor como a Apis mellifera, donde la colonia de abejas se observó como un superorganismo. En la primera parte de la investigación se corroboraron en laboratorio los efectos de toxicidad y repelencia del neem en el ácaro, observados en estudios previos; se observó que 2.64, 5.28, 10.56 y 21.12% de extracto de neem presentaron alta estabilidad en cuanto al efecto repelente; y 21.12% impidió que 98% de las varroas se posaran sobre pupas de abejas, lo que llevó a 100% de mortalidad de varroa en 72 h. La segunda etapa estuvo orientada a determinar los efectos del neem sobre...

Resistencia a la enfermedad de cría yesificada por colonias de Apis mellifera con eficiente comportamiento higiénico (Hymenoptera, Apidae)
Provedor de dados: 76
Autores: Invernizzi,Ciro.
In an apiary composed of 14 hygienic and 7 non-hygienic colonies of Apis mellifera Linnaeus, 1758 the presence of visible and capped mummies was recorded, one hygienic and 4 non-hygienic colonies showed symptoms of chalkbrood. Twenty-eight days after a massive contamination of the colonies with pollen patties containing Ascosphaera apis Olive &amp;amp; Spiltoir, 1955, the situation was almost identical to that at the beginning: the same 4 non-hygienic colonies still were infected and one hygienic colony that was healthy became infected. The high proportion of hygienic colonies that eliminated the disease symptoms suggests that they could maintain themselves healthy in spite of the presence of colonies with chalkbrood in the apiary.

Aprendendo a conviver com as abelhas-arapuás em sistemas agrícolas.
Provedor de dados: 14
Autores: DRUMOND, P. M.; RIBEIRO, M. de F.; KIILL, L. H. P.; SANTOS, R. S.
Apesar dos inúmeros benefícios associados às abelhas-sem-ferrão, algumas espécies são consideradas pragas agrícolas (como as arapuás, por exemplo), por danificarem caules, flores, folhas e/ou frutos, facilitando a entrada de organismos causadores de doenças, prejudicando o desenvolvimento das plantas, bem como reduzindo a quantidade e o valor comercial dos frutos. Esta publicação reúne algumas medidas que podem auxiliar os produtores rurais a minimizar os impactos negativos causados pelas abelhas-arapuás e a conviver com esse grupo de insetos, o qual desempenha importante papel no ecossistema.

Abelhas, prazer em tê-las.
Provedor de dados: 14
Autores: PEREIRA, F. de M.; LOPES, M. T. do R.; SOUZA, B. de A.
Você sabe que as abelhas são insetos? Os insetos são os seres mais adaptados do planeta e considerados a forma de vida dominante na Terra! Isso porque existem mais de setecentas mil espécies de insetos. São tantos e com formas de corpo tão diferentes que às vezes é difícil reconhecê-los. Mas todos eles têm algumas características em comum. Você quer saber o que abelha, borboleta, gafanhoto, pulga, formiga e mosca têm em comum? Todos têm um par de antena, três pares de pernas e um esqueleto externo, chamado de exoesqueleto. Existem outras semelhanças e várias diferenças. Alguns insetos, como o mosquito da dengue, causam doenças e são nocivos. Mas a maioria tem um importante papel na vida humana e de outros animais. Entre os insetos importantes, as abelhas...

In silico chemical library screening and experimental validation of novel compounds with potential varroacide activities
Provedor de dados: 5
Autores: Riva, Clémence; Suzanne, Peggy; Charpentier, Gabriel; Dulin, Fabienne; Halm-lemeille, Marie-pierre; Sopkova-de Oliveira Santos, Jana.
The mite Varroa destructor is an ectoparasite and has been identified as a major cause of worldwide honey bee colony losses. The use of yearly treatments for the control of varroosis is the most common answer to prevent collapses of honey bee colonies due to the mite. However, the number of effective acaricides is small and the mite tends to become resistant to these few active molecules. In this study, we have been looking for a new original varroacide treatment inhibiting selectively Varroa destructor AChE (vdAChE) with respect to Apis mellifera AChE (amAChE). To do this an original drug design methodology was used applying virtual screening of the CERMN chemolibrary, starting from a vdAChE homology sequence model. By combining the in silico screening...

Positiv externality of honey production
Provedor de dados: 31
Autores: Vanyi Arvane,   Georgina; Csapo,   Zsolt; Karpati,   Laszlo.
Bee-keeping and honey production has a long history in Hungary. Honey is an important and healthy food of people and it can be consumed without any human processing. The honey production has important role, too. Some researchers say that if honey bee will extinct the humanity in the world would also extinct. It is true since plant pollination by honey bees is very important. It is confirmed by researchers’ studies that plant pollination by honey bees has significant positive external impacts on potential yields in orchards. Although the contribution of honey production to the GDP in Hungary is only a few per cent, other benefits play more important role. One of them is the positive external effect – mentioned above – and the other is the contribution to...

Honey bees ( Apis mellifera ) visiting flowers of yellow melon ( Cucumis melo ) using different number of hives
Provedor de dados: 65
Autores: Ribeiro,Márcia de Fátima; Silva,Eva Mônica Sarmento da; Lima Júnior,Ivan de Oliveira; Kiill,Lúcia Helena Piedade.
Honey bees (Apis mellifera) pollinate melon (Cucumis melo) and improve production and quality of fruits. However, little is known about bee behavior and number of hives required. The aims of this study were to compare bees visiting flowers in crop areas with different number of hives (0, 1, 2, and 3), and to evaluate which is the best number. Flowers were observed (n=78) from 5 am to 6 pm, for five consecutive days, in four experimental areas (0.5ha each). Comparisons were made for male (MF) and hermaphrodite (HF) flowers, number of hives and fruit production. The HF were always more visited than MF. Most comparisons made for three hives presented significant differences, since visits increased drastically, competition among bees for floral resources...
