HONEY BEES AND BEE PRODUCTS AS MONITORS OF THE ENVIRONMENTAL CONTAMINATION

Effects of sub-lethal imidacloprid doses on the homing rate and foraging activity of honey bees
TLDR
The results show that almost all the control honey bees returned to the hive, and started again visiting the feeder between 2 to 5 hours after the release, and they were not seen during the following 24 hours, neither at the hive nor at the feeding site. Expand
Honey bee colony losses in Italy
TLDR
This work presents a meta-analysis of the honey beekeeping practices in Italy over a 25-year period from 1991 to 2002, which revealed clear trends in honeybee behaviour and in particular in the Lazio-Toscana region. Expand
Standard methods for maintaining adult Apis mellifera in cages under in vitro laboratory conditions
TLDR
The ultimate goal of this, and of all COLOSS BEEBOOK papers, is not to stifle science with restrictions, but rather to provide researchers with the appropriate tools to generate comparable data that will build upon current understanding of honey bees. Expand
Effects of imidacloprid administered in sub-lethal doses on honey bee behaviour. Laboratory tests
TLDR
Investigating if imidacloprid, provided in sub-lethal doses, could influence honey bee behaviour in the laboratory found that in the treated bees, the communicative capacity seemed to be impaired, and this could cause a decline in the social behaviour. Expand
Influence of brood rearing temperature on honey bee development and susceptibility to poisoning by pesticides
TLDR
It is concluded that adult honey bees reared at even slightly suboptimal brood temperature may be more susceptible to pesticide poisoning and be characterised by reduced longevity, thus, low temperature brood rearing could be another stress factor for colonies. Expand
Honey bee brood ring-test: method for testing pesticide toxicity on honeybee brood in laboratory conditions
TLDR
A new in vitro method to assess effects of pesticides on honey bee larvae and the LD50 for dimethoate 48 hours after an acute exposure found variability in values, which may be due to the colony origin, the season and larva heterogeneity at grafting. Expand
Monitoring of polycyclic aromatic hydrocarbons in bees (Apis mellifera) and honey in urban areas and wildlife reserves.
TLDR
The honeybee and honey were used to detect the presence of polycyclic aromatic hydrocarbons (PAHs) in several areas with different degrees of environmental pollution, and no positive correlation was found between the compounds detected in bees and those in honey. Expand
The puzzle of honey bee losses: a brief review.
TLDR
It is insufficient to explain CCD with only bee pathology studies, so research must be conducted on a wider series of causes to understand the fate of pesticide blends and to determine ways to enhance honey bee defence to diseases and parasites. Expand
