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.

The (semi-) arid area of West Africa is characterized by erratic rainfall that causes highly variable performances of cropping systems. This creates difficulties in strategic decision-making based on future-oriented production systems. In this pap...

The effects of ethanol on the H2O permeability and short-circuit current of the isolated urinary bladder of the toad, Bufo marinus, were investigated. Ethanol alone did not alter the flow of H2O along an osmotic gradient. The increase in osmotic H...
