    Neonicotinoid pesticides can reduce honeybee colony genetic diversity Neonicotinoid insecticides can cause a variety of adverse sub-lethal effects in bees. In social species such as the honeybee, Apis mellifera, queens are essential for reproduction and colony functioning. Therefore, any...

    Comparing bee species responses to chemical mixtures: Common response patterns? Pollinators in agricultural landscapes can be exposed to mixtures of pesticides and environmental pollutants. Existing mixture toxicity modelling approaches, such as the models of concentration addition and...

    Have a swarm that was sprayed before it moved into my trap. You couldn't tell there was a problem when you saw them going into the trap. The morning of day 3 they were moved into a hive. There has been major bee loss. The loss is not much as of yesterday. At least some of the bees...

    Genetics, Synergists, and Age Affect Insecticide Sensitivity of the Honey Bee, Apis mellifera The number of honey bee colonies in the United States has declined to half of its peak level in the 1940s, and colonies lost over the winter have reached levels that are becoming economically unstable...

    Neonicotinoid Insecticides and Their Impacts on Bees: A Systematic Review of Research Approaches and Identification of Knowledge Gaps It has been suggested that the widespread use of neonicotinoid insecticides threatens bees, but research on this topic has been surrounded by controversy. In...

    Neonicotinoid-Contaminated Puddles of Water Represent a Risk of Intoxication for Honey Bees In recent years, populations of honey bees and other pollinators have been reported to be in decline worldwide. A number of stressors have been identified as potential contributing factors, including the...

    Transcriptome Analyses of the Honeybee Response to Nosema ceranae and Insecticides Honeybees (Apis mellifera) are constantly exposed to a wide variety of environmental stressors such as parasites and pesticides. Among them, Nosema ceranae and neurotoxic insecticides might act in combination and...

    Forgive me for my ignorance, but I believe playing the devil's advocate is important before committing oneself to any cause, despite being a beekeeper myself. I'm wondering why the EPA continuously approves neonicotinoids despite implications that they are a major cause of Colony Collapse...

    Hi Everyone, My new neighbor bought and cleared property next door to my bee yard. He says he's deciding whether to plant a Pine tree farm or Fruit trees or maybe both. He told me he would spray his fruit trees in February. That is, if he plants fruit trees. I know this is a long way from...

    Transient Exposure to Low Levels of Insecticide Affects Metabolic Networks of Honeybee Larvae Given the changes we observe at the RNA and lipid level, it is reasonable so suspect that the synthetic neonicotinoid-class of insecticides are a factor driving the global decline of pollinating...

    The Neonicotinoid Insecticide Imidacloprid Repels Pollinating Flies and Beetles at Field-Realistic Concentrations Both Diptera and Coleoptera exhibited marked avoidance of traps containing imidacloprid at a field-realistic dose of 1 µg L−1, with Diptera avoiding concentrations as low as 0.01 µg...

    Molecular and Kinetic Properties of Two Acetylcholinesterases from the Western Honey Bee, Apis mellifera Western blot analysis revealed that AmAChE2 has most of catalytic activity rather than AmAChE1, further suggesting that AmAChE2 is responsible for synaptic transmission in A. mellifera, in...

    Hello! I'm new to this forum, and beekeeping. I live in the Florida Keys, and I am having trouble with the mosquito spraying they do here on a weekly basis. My issue is this: I am having bee death every time they aerial spray their adulticide over my property. They're spraying around 7 or 730...

    Okay, that was a teaser tagline. It hasn't happened yet, but I think it might be. Anyway, we have a guy here spraying and telling homeowners not to worry about the honey as "robber bees" would take care of it. I just pulled 5 gallons of honeycomb (not including the brood comb) out of person's...

    I wrote a story for the papers in our region, bringing up the concerns of local farmers, beekeepers etc. about the state's (Massachusetts) plan to spray Anvil to kill mosquitoes. I want to do a follow-up on results that people like yourself experience when this kind of spraying is done. There...
