Abstract:

A study was carried out to determine the effectiveness of thymol (powdered form) with oxalic acid against an ectoparastic mite, Varroa destructor populations in honey bee, Apis mellifera ligustica (Hymenoptera: Apidae) colonies in the autumn. Thymol 2, 3 and 4gm with 3% oxalic acid was applied to twenty honeybee colonies thrice on different dates. The mean number of Varroa mite fallen by treatments T1, T2 and T3 was found 348±2.34, 412±2.87 and 523±3.24respectively. The highest number of mites fell in T3and was found significant (F= 34.40, P < 0.05) from all other treatments. The percent efficacy of Varroa mite by different treatments T1, T2 and T3 was found 82±1.45, 86±1.46 and 92±1.48 respectively. The results showed a significant difference between efficacies (F = 233.28, P < 0.05). The amount of honey produced from different colonies treated with T1, T2 and T3 was found 12±0.11, 15±0.13 and 24±0.16respectively and was found significant (F= 45.35, P < 0.05).The treatment T3 showed maximum number of fallen mites, highest percent efficacy and amount of honey produced which clearly showed that treatment T3 (Thymol 4gm + 3% OA)to be the most effective treatment against Varroa mite.
