Rearing honey bee colonies in laboratory for control experiments against Varroa mite in Egypt [ ]


Rearing honey bee colonies in the laboratory in Dept. of Zool. , Fac. of Agric. ,Cairo Univ. by using of Apiguard , formic acid and sulfur to control varroa mite. Rate of efficacy %, number of dead mites on white card board, number of varroa mite on 100 honey bee worker, number of varroa on 20 brood cells were recorded and codified to compare among three treatments. These treatments were repeated weekly for 8 times through the experiment. Formic acid and sulfur preparations were saturated in cardboard strips and one strip was put in each colony. The acaricide Apiguard was used of 50 gel upper Frames of each colony. It was found that the efficiency of formic acid was the superior treatment followed by Apiguard then sulfur, being 92.4, 86.3, 76.9% efficiency, respectively.
