Honey Bees
Sub-lethal doses of neonicotinoid and carbamate insecticides reduce the lifespan and alter the expression of immune health and detoxification related genes of honey bees (Apis mellifera)
Authors: Hassan Tarek, Mollah Md. Hamiduzzaman, Nuria Morfin and Ernesto Guzman-Novoa
Honey bees (Apis mellifera) are exposed to sublethal doses of insecticides, but little is known about insecticide effects on their survivorship associated to health-related gene expression. To test the effect of sublethal doses of clothianidin, imidacloprid and carbaryl on the lifespan and health of honey bees, workers were or.. Read More»

Sequential hygienic behavior in Carniolan honey bees (Apis mellifera carnica)
Authors: K.P. Gramacho and L.S. Gon�§alves
We examined the sequence, order or steps of hygienic behavior (HB) from pin-killed pupae until the removal of them by the bees. We conducted our study with four colonies of Apis mellifera carnica in Germany and made four repetitions. The pin-killing method was used for evaluation of the HB of bees. The data were collected ever.. Read More»

Comparative study of the hygienic behavior of Carniolan and Africanized honey bees directed towards grouped versus isolated dead brood cells
Authors: K.P. Gramacho, L.S. Gon�§alves
In Apis mellifera, hygienic behavior involves recognition and removal of sick, damaged or dead brood from capped cells. We investigated whether bees react in the same way to grouped versus isolated damaged capped brood cells. Three colonies of wild-type Africanized honey bees and three colonies of Carniolan honey bees were use.. Read More»

Evaluation of the time of uncapping and removing dead brood from cells by hygienic and non-hygienic honey bees
Authors: Maria Alejandra Palacio, Jose Manuel Flores, Emilio Figini, Sergio Ruffinengo, Alberto Escande, Enrique Bedascarrasbure, Edgardo Rodriguez and Lionel Segui Gon�§alves
Most research on hygienic behavior has recorded the time taken by the colony to remove an experimental amount of dead brood, usually after one or two days. We evaluated the time that hygienic (H) and non-hygienic (NH) honey bees take to uncap and remove dead brood in observation hives after the brood was killed using the pinki.. Read More»

Bee�s morphometrics and behavior in response to seasonal effects from ecoregions
Authors: A.R.S. Sousa, E.D. Ara�ºjo, K.P. Gramacho and L.A. Nunes
In the present study, we used morphological and behavioral analyses to assess the effects of seasonality and morphoclimatic patterns on the morphology, behavior, and distribution of 71 colonies of Africanized honey bees in 3 distinct ecoregions (Zona da Mata, Agreste, and Sertão) within the State of Sergipe, north-easte..

Is the number of antennal plate organs (sensilla placodea) greater in hygienic than in non-hygienic Africanized honey bees?
Authors: K�¡tia Peres Gramacho, Lionel Segui Gon�§alves, Ant�´nio Carlos Stort, Adriana Backx Noronha
Hygienic behavior is a desirable trait in honey bees (Apis mellifera L.), as hygienic bees quickly remove diseased brood, interrupting the infectious cycle. Hygienic lines of honey bees appear to be more sensitive to the odors of dead and diseased honey bee brood, and Africanized honey bees are generally more hygienic than are.. Read More»
