  • Almond joy! - Victory for bees | Honey Bee Haven
    crops which honey bees are trucked in from around the country to pollinate each February Imidacloprid belongs to a class of systemic neurotoxic pesticides known to be particularly toxic to honey bees neonicotinoids As systemics they permeate the plant from the roots up and are expressed in pollen nectar and guttation droplets like pesticide dew Bad for bees bad for almonds New research suggests that even in very small doses neonicotinoids create big problems for bees Imidacloprid likely weakens their immune systems and in combination with other threats like parasites contributes to the alarming decline in bee populations termed Colony Collapse Disorder Almond orchards are almost totally reliant on commercial beekeepers Healthy bees and the crops they pollinate are critical for California business The state produces 80 of the world s almonds and the orchards are almost totally reliant on commercial beekeepers operating inside and outside the state Small and large businesses alike beekeepers almond growers and almond processors benefit when the use of systemic pesticides is reduced Two problems Residues permeate plants accumulate over time Bayer s call to halt imidacloprid s use on almonds was prompted by concern from California s Department of Pesticide Regulation DPR In 2009 the agency observed two serious problems with Bayer s product high levels of imidacloprid are found in leaves and blossoms of treated plants and residue levels on plants increase over time accumulation from previous applications As a result of these findings the state agency launched an extensive review of imidacloprid and its counterparts Bayer and other manufacturers have largely complied with agency requests for more research But when it came time to review the impacts of their most profitable pesticides on almonds and bees the company asked for a withdrawl rather than move forward As an anonymous insider reports With

  • Even small doses are big trouble for bees | Honey Bee Haven
    that seven in ten U S bee hives are infected with the parasite Nosema ceranae A study released in June found that 47 of infected bees die However when also exposed to low levels of pesticides the mortality rate jumps to 71 On their own both parasites and pesticides pose dangers to bee populations But collectively their impact is dramatically increased even when the pesticide exposure is minimal The study showed that a daily exposure to 1 100 th concentration of the LD50 the dose at which 50 of the population dies significantly affects the mortality rate of N ceranae infected honey bees Bees have been dying off in droves around the world since the mid 1990s First in France then in the U S and elsewhere colonies have been mysteriously collapsing with adult bees disappearing seemingly abandoning their hives In 2006 about two years after this phenomena hit the U S it was named Colony Collapse Disorder or CCD It s becoming increasingly clear that multiple interacting causes are at play in CCD and that immune system damage is a key factor Bees provide for us all Honey bees pollinate one in every three bites of food we eat
