Abstract
American foulbrood (AFB) Paenibacillus larvae and European foulbrood (EFB) Melissococcus plutonius are harmful for honey bee colonies. Many antibiotics were used, but mischief on Human healthy. Here, the natural products [Honey bees, Cinnamon (Cinnamomum zeylanicum), Cloves (Syzygium aromaticum), Propolis, and Thymol (Thymus vulgaris)] were evaluated against AFB and EFB bacteria in laboratory and field. In laboratory Thymol had the highest effect on AFB with different concentrations and had a total mean of 3.37 ± 1.03 cm of circle around disc diffusion. In contrast, Thymol had the lowest effect on EFB with a total mean 0.33 ± 0.15 cm. The cloves had the highest effect on EFB with a total mean of 4.50 ± 2.00 cm and fourth level effect on AFB with a total mean of 0.73 ± 0.20 cm. Propolis had the second level effect on AFB and EFB with total mean 1.15 ± 0.93 cm on AFB and 1.49 ± 0.95 cm on EFB. In Apiary, Thymol has the biggest change amount of brood development of 5.457 in each check time for AFB with a rate of 25.8% increase of capped brood through all the treated period contrast with EFB. On the other hand, Cloves had the biggest change amount of 5.371 in each check time treatment with a rate of 25.3% increase of capped brood through all treated periods. In addition, the mean weight of healthy pupae was 1.747 ± 0.172 mg. Pupae was infected by AFB weighed 1.101 ± 0.042 mg and pupae was infected with EFB recorded 1.344 ± 0.119 mg.
