The Varroa mite (Varroa jacobsoni Oudemans) has become the most devastating pest of honeybees Apis mellifera worldwide. It is also considered a major concern of a beekeeper as its heavy infestation can cause death of honeybees and decrease honey production. The Varroa mite resistance to many acaricides was reported in several previous studies. The potential efficacy of Huwa-San TR50 on Varroa was tested as an alternative nondestructive method in controlling Varroa mite. Secondary effects on honeybee Apis mellifera (Apis mellifera lamarckii) was also recorded. Huwa-San TR50 produced mortalities of 30 and 45% after 24 h of exposure at 1000 and 2000 ppm, respectively. Moreover, there was insignificant difference between 3000 and 4000 ppm as they had the same mortality percentage (75%). The secondary effect of Huwa-San TR50 on honeybees was none with no significant effects on their life or behavior after exposure to all Huwa-San TR50 concentrations used in this study via contact and feeding. Finally, 3000 ppm of Huwa-San TR50 could be recommended for use as acaricidal agent in controlling Varroa mites and should be a part of controlling strategy of Varroa mites to minimize the residual effects of acaricides on honeybee and its products. This strategy can also play an important role in integrated pest management programs (IPM) as Huwa-San TR50 was found to be safe to honeybees and other beneficial insects and mites.
