| 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. | ||||
