Abstract


The efficiency of the anise (Pimpinella anisum LINN.) oil was tested to control varroa mite (Varroa destructor Anderson & Trueman) on the honey bee (Apis mellifera Linnaeus) by evaporation using a smoker or an electrical bobbin connected to a dry battery. Results showed that fumigation of a piece of sackcloth saturated with 4 ml of Anise oil per colony gave an efficiency of 56.2%, there was a significant difference at P=0.01 in comparison with untreated control. Meanwhile, the evaporation of 1.5 ml (0.5 ml of Anise oil and 1 ml Ethanol) using an electrical bobbin gave an efficiency ranged between 82.5 and 87%, the average was 84.4% and there was a significant difference at P=0.01 in comparison with untreated control. Results demonstrated that the addition of Ethanol to the Anise oil maintain its efficiency and decreased its loose. Evaporation of 1.5 ml of Anise oil per colony gave an efficiency of 89.2%, meanwhile, adding 0.5 ml of Ethanol to 1 ml of Anise oil to the colony gave an efficiency of 86.3%. The efficiency was decreased to 72.3% in case of mixing 0.5 ml of Anise oil with 1 ml of Ethanol, where the evaporation of 1.5 ml Ethanol (treated control) per colony gave an efficiency of 41.5%. There was a significant difference at P=0.01 between the treatments and the treated control. We recommend using the Anise oil because it is a natural product, safe on honeybee products and can be used during the year.
