There were a total of 1 colony in the bee yard. There was 1 affected colony. There were an average of 15 frames of bees, 12 frames of brood, and 5 frames of pollen and honey. The following pests were present in the affected bee yard in the past year; Chalkbrood, wax moth, nosema, varroa mite and skunks. Additional food sources provided to the bees included sugar syrup and pollen supplement (patty) in the spring 2014. In fall 2013, apivar was applied at a rate of 2 strips to treat varroa mites. In the fall 2013 the antibotic fumagillan-B was applied to hive, oxytetracycline was applied in the spring 2014. the rodenticides jaguar (26673) was used in Fall/winter 2013. Placed bait under hive during winter to kill any mice in/around bee box. Bees were actively foraging when incident occurred and when questionnaire was being filled out. There were 0-500 dead bees observed outside the hive. Adult bee symptoms included shaking/trembling/twitching, crawling and disoriented. Brood symptoms included dead larvae/pupae on bottom board. no queen symptoms observed. The weather at the time of the incident was sunny and not overly windy - maybe light breeze, temperature was 10-12 C. The last rain event occurred on 2014-05-25 (AM). Beekeeper was unsure what caused the incident - but potentially seed treatment used on corn on field to the south. field south of bee yard was seeded on Saturday, May 24, 2014 with corn. Saturday was a very windy day. Wind was blowing from the south so dust from the field was moving from seeded corn field directly north into the bee yard. Bees were observed on SUnday, May 25, 2014 with no unusual symptoms. weather was cool and damp so bees had low activity. Symptoms of dead bees and affected bees were observed on Monday, May 26, 2014 around 11:00am. Beekeeper observed dead bees at the entrance and out side of the hive. Also noticed bees twitching and crawling around the hive and in the grass. Hive had come out over winter strong with no noticeable disease or trouble. therefore, beekeeper thought it could be related to corn seeding so phoned provincial specialist. Sample of dead bees taken had positive detects for thiamethoxam and clothianidin. Sample of live bees taken had no detected active ingredients.
