Parasite-insecticide interactions: a case study of Nosema ceranae and fipronil synergy on honeybee
In ecosystems, a variety of biological, chemical and physical stressors may act in combination to induce illness in populations of living organisms. While recent surveys reported that parasite-insecticide interactions can synergistically and negatively affect honeybee survival, the importance of sequence in exposure to stressors has hardly received any attention. In this work, Western honeybees...
متن کاملDisruption of oxidative balance in the gut of the western honeybee Apis mellifera exposed to the intracellular parasite Nosema ceranae and to the insecticide fipronil
The causes underlying the increased mortality of honeybee colonies remain unclear and may involve multiple stressors acting together, including both pathogens and pesticides. Previous studies suggested that infection by the gut parasite Nosema ceranae combined with chronic exposure to sublethal doses of the insecticide fipronil generated an increase in oxidative stress in the midgut of honeybee...
متن کاملHigh-level resistance of Nosema ceranae, a parasite of the honeybee, to temperature and desiccation.
Resistance of Nosema ceranae to different exposure conditions has been evaluated by using Sytox green and DAPI (4',6-diamidino-2-phenylindole) to test spore viability. High thermotolerance at 60 and 35 degrees C and resistance to desiccation were observed. However, a significant decrease in viability after freezing and a rapid degeneration of spores maintained at 4 degrees C were also detected.
متن کاملHow natural infection by Nosema ceranae causes honeybee colony collapse.
In recent years, honeybees (Apis mellifera) have been strangely disappearing from their hives, and strong colonies have suddenly become weak and died. The precise aetiology underlying the disappearance of the bees remains a mystery. However, during the same period, Nosema ceranae, a microsporidium of the Asian bee Apis cerana, seems to have colonized A. mellifera, and it's now frequently detect...
