A new veterinary medicinal product called Varterminator for varroa mite control has been developed. The medicine is made of a gel containing formic acid (FA) and is able to produce a passive evaporation of FA and to guarantee a high degree of safety for the bee colony. To verify the efficacy of the treatment and the effect on eggs, larvae, adult bees and queens, clinical trials were performed in several apiaries spread throughout Italy, under different climatic and regional conditions. The average acaricide efficacy rate was more than 95%, with a maximum level of 99%. With regard to safety, no adverse reactions were observed on larvae, adult bees and queens when compared to untreated colonies. One adverse reaction was noted, however, a high mortality of eggs. The eggs were quickly replaced by the queen in a few days, without affecting the wellbeing of the colony. The results showed that the acaricide is efficacious and safe for colonies. The medicine can be used with brood, throughout the season of the bee activity. Moreover, the product is ready-to-use, safe for users and suitable for organic farming.

Abstract

A new veterinary medicinal product called Varterminator for varroa mite control has been developed. The medicine is made of a gel containing formic acid (FA) and is able to produce a passive evaporation of FA and to guarantee a high degree of safety for the bee colony. To verify the efficacy of the treatment and the effect on eggs, larvae, adult bees and queens, clinical trials were performed in several apiaries spread throughout Italy, under different climatic and regional conditions. The average acaricide efficacy rate was more than 95%, with a maximum level of 99%. With regard to safety, no adverse reactions were observed on larvae, adult bees and queens when compared to untreated colonies. One adverse reaction was noted, however, a high mortality of eggs. The eggs were quickly replaced by the queen in a few days, without affecting the wellbeing of the colony. The results showed that the acaricide is efficacious and safe for colonies. The medicine can be used with brood, throughout the season of the bee activity. Moreover, the product is ready-to-use, safe for users and suitable for organic farming.
