There were a total of 3 colonies (2-double brood box & 1 single) in the bee yard and two dead colonies (feb/march 2014). There were 3 affected colonies. The following pests were present in the affected bee yard in the past year; American foulbrood (spring 2013). Other: suspected pesticides effect over winter caused weak hives and led to loss of two. Additional food sources provided to the bees included sugar syrup (oct-13). Formic acid (65%) and oxalic acid were applied to the hives to treat varroa. (formic acid pads: april 19, 2014 for 21 days; fall 2013 - Sept 18 to Oct 28, oxalic acid: Nov 2013). In 2013 (Oct 10, Oct 14, Oct 20); and 2014 (Apr 22, May 2 & 7) the antibotic oxytetracycline was applied to the hives at oxysol 62-5, to treat ABF. Bees were actively foraging at time of intial mortality; actively foraging when questionnaire being filled out; dead bees had pollen on their legs; lack of foragers returning to hive; other: a drop in bee population and population remained low in numbers - unable to rebuild up to a satisfactory level. There were 0-500 dead bees observed inside, outside and between the lid and inside cover of each hive. bee population not building up - same as 2013 - bees foraging with pollen bundles walking around but not accessing the inside of the hives. brood not building up. no queen symptoms observed.
