There were a total of 1 colony in the bee yard. There was 1 affected colony. There were an average of 10 frames of bees. The following pests were present in the affected bee yard in the past year; AFB (american foul brood) and likely varroa mite. Additional food sources provided to the bees included sugar syrup (Spring 2014). On May 1st for one month, Thymovar was applied 2 waffers per colony to treat varroa mite. May 1-31st 2014 the antibotic ocytetracycline was applied to the hives at 1 heaping tbsp on top of frames, to treat AFB. Bee were actively foraging when incident occurred; actively foraging when questionnaire being filled out; and dead bees had pollen on their legs. There were 0-500 dead bees observed outside of each hive. Adult bee symptoms included shaking/trembling/twitching, crawling, disoriented and tongues out. Brood to bee ratio is off, could be due to a population lost. The weather at the time of the incident was sunny. the beekeeper believes that neonic pesticide was th cause of the incident. Bker is new to beekeeping - first started in 2014 -she started with 2 hives - one lost last fall due to foul brood - the second hive overwintered and this hive was the hive that she noticed the pesticide poisoning symptoms in. - she did not see a big kill; while the effect were first observed on May 26, she did not collect any dead/ affected bees until May 28. she collected Bees over a number of days - the majority were collected between May 28 and May 30. At the time of our inspection no adverse effects were observed with the affected hive; the bees were actively foraging, bringing pollen back to the hive. There were alot of hay/ pasture fileds in the area as well as a few fields close by that were planted to corn (corn was at the coleoptile stage on the date of my visit). Sample of dead bees taken had positive detects for clothianidin and carbaryl. Sample of comb pollen taken was positive detects for thiamethoxam, clothianidin and inidacloprid.
