Abnormal behavioural effects
Reproductive impairment
There were a total of 19 colonies in the bee yard. There were 6 affected colonies. The average number of dead adult bees per colony was 0 - 500 and found dead outside the hive. Bees were actively foraging at the time of the incident. After the adverse effects there was a noticeable decline in foraging. Some dead bees had pollen on their legs.Adult bee symptoms included shaking, trembling, twitching, vomit, regurgitation, crawling, disoriented. Brood symptoms included dead larvae/pupae on bottom board, dead larvae/pupae outside of colony, additionally not too sure about spotty brood. Queen symptoms included dead queens, emergency/supersedure queen cells, queen stopped laying, additionally lost 2 queens and queens are only laying drones. Sample of pollen taken from affected hive (hive A - weak hive affected pollen comb) had positive detects for Carbendazim, Clothianidin, and thiamethoxam. Samples of live bees taken from the strong hive (affected Yard 1 and affected hive B) had no detected active ingredients. Sample of dead bees taken from affected hive had positive detects for clothianidin, pyrimethanil and thiabendazole. The weather at the time of the incident was dry, more died after a rain. Prior to the incident, there was an average of 10 frames/box of bees (very healthy); there was good brood production, (noticed other hives were very strong); frames of pollen and honey were good. The following pests were present in the affected bee yard in the past year, nosema and varro a mite.After the incident there was no change in the frames of bees; (other than loss of 1 cup of bees) frames of bees; the hives seem to be bouncing back, new eggs being laid, and there was no change with frames of pollen and honey. Additional food sources provided to the bees included sugar syrup and honey, feeding since May 10 to discourage foraging. In 2012, the following treatments were applied to the hives: formic acid, antibiotics. In 2013, the following treatments were applied to the hives: antibiotics. Information on crops located near the beeyards: approx.. 5 ha of what was assured to be corn, based on the description of the plants was 200 m from the beeyard. Bees were foraging at the time of planting. Soybeans were previously planted, seeding date is not known. A water treatment facility is located closed to the yard. Corn was planted May 8. Bkeeper and wife saw a large planter with seed reservoir. Next day (May 9), dead bees in front of hives. May 10 more dead bees (2 to 3 days). He began feeding sugar syrup may 10 to discourage foraging. Bkeeper estimates that 50% of total bee population lost. Now May 17 - colonies seem to be bouncing back, lots of brood is hatching. Beekeeper noted that bees have an arched shape after the incident. Strongest hives are impacted. Inspectors saw twitching/disorientation symptoms of living bees at the time of site visit. Strongest hives are impacted. Not too sure what he (bkeeper) can do other than feeding sugar syrup, too hot to close up boxes.
