Control of the nosema disease poses a major challenge, and therefore, treatment of this serious parasitic disease using natural preparations could be of great benefit. The aim of this study was to tes...
A honeybee colony, part of an apiary of nine, showed abnormalities in brood pattern and was thus presented for study. A classic veterinary medicine approach has allowed the diagnosis of a severe case ...
The proteolytic system on the body surface of the honey bee has been insufficiently researched. In this study the body surface proteolytic activity was examined in queens at various developmental stag...
Foraging behaviour is one of the distinctive behaviours of honey bees, Apis mellifera. This behaviour is the link between the honey bee colony and the ambient environment. Therefore, various in-colony...
The histochemical activity of aminopeptidase and non-specific esterase, both important enzymes of intermediate metabolism in the mid gut of honeybees (Apis mellifera), was investigated. Nosema disease...
An important area of physiology of the honeybee (Apis mellifera) is chemical communication between individuals and castes in the swarm, which maintains its integrity and function. The highly complex s...
The histopathological structure as well as content and distribution of mucosubstances in the mid-gut mucosa of the honeybee (Apis mellifera) treated with the phyto-pharmacological preparation Nozevit ...
Migratory and local bees in Massachusetts were analyzed for seven viruses. three were detected: black queen cell virus (BQCV), deformed wing virus (DWV), and sacbrood virus (SBV). DWV was most common,...
Honeybee populations around the world are experiencing a decrease in colony numbers probably due to a combination of different causes, such as diseases, poor nutrition and frequent applications of ins...
Toxicity of Thiamethoxam, Behavioral Effects and Alterations in Chromatin of Apis mellifera L., 1758 (Hymenoptera; Apidae)。
Mimosa tenuiflora (Willd.) Poir. (Mimosaceae) is a xerophilous plant which is very common in degraded areas in the Brazilian semi-arid region, including areas of beekeeping. The ingestion of leaves fr...
【目的】对蜜蜂(Apis mellifera L.)蜂王与工蜂级型分化期的蛋白质组进行比较,以探明蜂王和工蜂在级型分化时期蛋白质表达调控方面的异同。【方法】采用双向电泳建立蜂王和工蜂级型分化期蛋白质组表达 谱,获得图谱中蛋白质表达的数量、表达量、等电点和分子量等信息,然后进行比较蛋白质组研究。【结果】在幼虫3日龄,蜂王表达288个蛋白质,工蜂表达259个蛋白质,2种级型蜂共有蛋白质为156个,其中...

concentrations of the organic pesticide Bioganic® on mortality was assessed at 11 different time intervals in Africanized honey bees (Apis mellifera L.) as was direct application of the pesticide ...
Every week over a 1-year period, pollen samples obtained from traps fitted on 4 hives were analysed microscopically in order to identify pollen sources and to determine how these sources varied durin...
