Providing an alternative oxalic acid vaporizer to bee farmers for enhanced bee keeping


         A major reason for the inability of honeybees to produce abundant honey is the presence of varroa mites. Beekeepers have come up with ways to exterminate the varroa and one of these methods is the utilization of oxalic acid either in the form of a liquid spray or fumes. However, the currently used oxalic acid vaporizer used is bulky, prone to overheating, and is manually operated. In addition, other chemical-based bee mite treatments are very costly and are not locally available.

Through this program, a better oxalic acid vaporizer that is more portable, affordable, and operates within an ideal range of temperatures was introduced. With the fumigator’s capability to diffuse oxalic acid at any time, Mr. Edmund Benavidez, the Executive Director of SLU-EISSIF, agrees that the new machine has actually overcome one major defect of their old machine, which pertains to the formic acid’s difficulty to evaporate during cold or rainy season. Consequently, orientation and training about the use of this alternative gadget had been conducted for bee farmers.

The prototype of this gadget was already been turned over to EISSIF for deployment and technology transfer purposes. Through EISSIF, the new machine may be leased to the bee farmers at a much lower price.
