Control of the mite Varroa jacobsoni in hives in Israel by using formic acid

, : Control of the mite Varroa jacobsoni in hives in Israel by using formic acid. Hassadeh 66(10): 2117-2120

The control method used was as follows: from 15 to 25 ml formic acid (85%) were poured on cotton wool in a plastic petri dish that was placed on top of the brood frames in the hive. Space for the dish was provided by placing a wooden frame, 5 cm high, between the top of the hive box and the cover. Eleven colonies which were weak and infested with Varroa were used to test the method. Before the first treatment, the hives were inspected and mites were seen infesting the bees.

Rate of evaporation was controlled by altering the level of acid or the size of the dish; the resulting concentration of acid in the hive atmosph...

Formic acid sampling was compared to 5 other commonly used varroa detection methods. Sampling with formic acid was shown to be a useful tool when checking honey bee (Apis mellifera) colonies for varroa; however, formic acid did not result in a rap...

This would be useful in effective pest control, in the development of new control methods and in the study of the population dynamics of this mite. The...
