The potential of beekeeping to mitigate the exposure of rural sub-Sahara African farmers to economic stochasticity has been widely promoted by an array of development agencies. Robust outcome indicators of the success of beekeeping to improve househo

In this study an important and often neglected aspect of gene expression studies in insects, the validation of appropriate reference genes with stable expression levels between sample groups, is addressed. Although in this paper the reference gene se

Bidirectional interactions between the immune and nervous systems are well established in vertebrates. Insects show similar neuro-immune-behavioral interactions to those seen in vertebrates. Using quantitative real-time PCR, we present evidence that

The study evaluated the technical feasibility of distinguishing the different honeybee blood cells by flow cytometric analysis with and without staining by 3 lectins: soybean agglutinin (SBA), concanavalin A (ConA) and wheat germ agglutinin (WGA). Fl

The aim of this investigation was to establish whether Varroa destructor can play a role in the transmission of Paenibacillus larvae larvae spores from infected to healthy bee colonies. Mites, collected from an Apis mellifera carnica colony heavily i

The early infection of the honeybee midgut by the microsporidian parasite Nosema apis was examined with both light and electron microscopy. Newly ingested spores were found closer to the apex of the epithelium as they moved toward the distal end. The
