There were a total of 31 colonies in the bee yard. There were 31affected colonies. No pests in the past year. Additional food sources provided to the bees included sugar syrup (barrel fed in fall after the last honey crop is harvested) and pollen supplement (on the hives right now, homemade). In the fall, apivar was applied to the hives. In fall the antibotic fumagillan-B was applied to the hives. Bees had dead bees had pollen on their legs, too cold/windy for foraging during inspection. Must have been foraging at some point: pollen on legs of dead/dying bees. There were 0-500 dead bees observed outside (under hives) of each hive. Adult bee symptoms included crawling and wings flared out on dead bees. Too cold to inspect brood frames - did not want to chill brood. no queen symptoms observed. The weather at the time of the incident was overcast and windy from the rest, temperature was cool 8 C. Beekeeper believes neonitinoids were the cause of the incident. Bees in the hive look on average like everyone elses bees in this area for this time of year (in terms of cluster size, pollen stores etc). Cluster size is decent. Beekeeper reported wings flared forward. Very little of this was observed, as the beekeeper had collected most dead bees that morning. Wax seen in front of hives, or down in bottom board can be seen as a sign of a weaker hive that is being robbed. This was observed in some hives. Fairly strong wind in NW direction during inspection. Quite cold, no foraging. Only bees of hive currently being inspected were flying- afterwards they all went back in hive. Many dead bees out front, were old, decomposing. NORMAL winter-kill clean out. Several of inspected hives were lifted, and up to ten dead/dying fresh bees were found UNDER the bottom board. OMAF inspector thought they couldn¿t get into hive but were trying to get to some shelter. Water sample taken from edge of marsh area. 30m from hives, bee inspector felt this would be a year-round water source for the bees. Bees were seen crawling up to 5 feet in front of hives (by inspectors). [name] called [name] after she left inspection to tell her that as it warmed up there were even more bees crawling around (indication that mortality event is ongoing, assuming those bees will die). All hives were requeened in the fall. Sample of dead bees taken had positive detects for imidacloprid. Sample of dead bees taken had no detected active ingredients. Sample of pollen comb had positive detects for thiamethoxam and clothianidin.
