  • Banner week in bee science: Zombie flies & poisonous 'planter exhaust' | Honey Bee Haven
    from all sides The January 3rd pesticide study out of Purdue University has yet to be covered in a major media outlet but it confirms a series of especially damning findings bees face multiple pesticide exposure routes pollen dust soil nearby untreated plants planter exhaust at critical times as nurse bees are emerging and at toxic levels for a suspect class of pesticides neonicotinoids on a common crop corn that commercial beekeepers say is particularly harmful to their hives Pollen collected directly from the treated plants was contaminated by clothianidin as expected but bee collected pollen samples showed higher levels indicating additional pathways of exposure This finding is of particular concern because clothianidin is even more toxic when ingested orally by a bee 2 8 ng bee vs 22 44 ng bee contact toxicity Overall the issue investigated and confirmed by the Purdue study is that bees are getting it from all sides in a mixture of modalities that probably ultimately defy quantification Bees in and near corn fields face contact toxicity drift of soil or planter exhaust and oral toxicity ingestion of contaminated pollen or guttation droplets from a suite of pesticides the most toxic of which persists and therefore accumulates for years in the environment Clothianidin which is among the most bee toxic of the neonicotinoids has a half life of between 148 and 1 155 days Poisonous planter exhaust dandelions really bad timing Among the Purdue study s PDF new and potentially surprising findings are the establishment of two previously unrecognized exposure routes one through contaminated planter exhaust and another through untreated but contaminated dandelions in nearby fields from which bees are known to gather nectar and pollen Extremely high levels of clothianidin and thiamethoxam both neonicotinoids were found in planter exhaust material exuded into the soil and air during and after the planting of treated corn seeds Planter exhaust tends to be especially mobile in the environment and is likely dispersing to nearby fields and other plants Timing is another special concern pursued by this study Corn is planted throughout the Midwest from mid April through early May when the energy requirements of bees are increasing rapidly as increased foraging is required as hives prepare for colony growth Recent studies have established the potential for cascading sublethal effects when developing bees are exposed to pesticides within the hive through stored pollen e g royal jelly brood comb During the period observed in the Purdue study emerging nurse bees were feeding on pollen reserves in the form of royal jelly Authors calculated that at the levels observed a new bee would consume 50 of the oral LD50 a common measure of acute toxicity the amount required to kill 50 during the 10 days it spends as a nurse bee 10 fold more contaminated Readers may recall that in December of 2010 PAN and Beyond Pesticides joined beekeepers in urging EPA to take action to protect bees from clothianidin on corn and canola These two crop uses were
