Death
There were a total of 12 colonies in the bee yard. There were 12 affected colonies. Number of frames of bees, brood and honey are on track for this time of year. The following pests were present in the affected bee yard in the past year; varroa mite (high levels august 2013). Additional food sources provided to the bees included Pollen supplement (on hives now) and sugar syrup (only if needed in spring). In fall 2013, Mite wipes and oxalic acid were applied and apivar was applied in the spring of 2014. In Fall the antibotics fumagilin-B and oxytetracycline were applied to the hives, oxytetracycline was also applied in the spring. Bees were actively foraging when original mortality was observed, actively foraging when questionnaire being filled out, and lack of foragers returning to hive. too soon to tell if after the adverse effects there was a notieable decline in foraging. There were ~300 visible, more were likely scavenged by insects dead bees observed outside of each hive. dead bees had tongues out, no pollen on legs, quite fresh, fuzzy. Have not been rained on (would have dies within 24hrs of inspection). Adult bee symptoms included shaking/trembling/twitching, crawling, disoriented, vomit/regurgitation. Additionally, tongues out (dead), some crawling, clinging to grass, twitching on back. Brood symptoms included spotty brood production (in one hive) and very minor amount of chalkbrood being dumped out of hive. Queen symptoms included unusual laying pattern (hive 5 observed) - pollen & nectar mixed in with capped brood, odd. other than that no queen symptoms observed. The weather at the time of the incident was sunny, temperature was between 10-20 C. Rained on and off all week. Beekeeper believes In general, had very high over winter losses and the hives are having trouble building up- pesticides are playing a role. there was heavy frost the last 2 nights, so eaves/blossoms don't like healthy but majority were already pollinated - apples will survive. -Bumble bees and other pollinators have been working flowers, but honey bees not as much. 12 hives arrived last week (Tues - wed), and will stay until approx. May 25. no insecticides have been sprayed yet -flowers are in various stages of bloom (good for bees and apples). Sample of dead bees taken had positive detects for clothianidin and myclobutanil. Sample of pollen comb taken had positive detects for clothianidin and acetamiprid. General Notes from Discussion with [name] (BKer) - In 2013 spring @ Home Yard, there were 600 hives and 5 barrels of sugar syrup. No bees were foraging. At other yards, the bees were thick in the air. 2014: - first- pass of over-winter loss checks had 50% loss, second pass showed 85-90% winter loss. - High levels of mites in the Fall 2013. Hives were all treated (see section 6) -no mite found during this inspection
