Isolation and determination of bacterial microbiota of Varroa destructor and isolation of Lysinibacillus sp. from it

Abstract

Abstract Background The importance of bees for environmental health is known. Within the scope of this importance, it is of great importance to protect the health of bees and to prevent colony extinction. In this context, it is very important to develop effective methods in combating microorganisms, parasitoids, mites and organisms that cause disease or harm in bees. Both use different methods in terms of bee health. Result In this study, the possibility of the bacteria isolated from Varroa destructor mite being bioinsecticide was investigated. Accordingly, six bacteria were isolated from the mite. Isolated bacteria were analyzed according to biochemical tests, molecular analysis, optimum growth pH and phylogenetic tree drawn as Pantoea dispersa (GV1), Lysinibacillus macroides (GV3), Bacillus mycoides (GV4), Lysinibacillus fusiformis (GV5), Pseodomonas lutea (GV5), Lysinibacillus varians (GV7). Lysinibacillus sp. The entomopathogenic feature of Lysinibacillus sp. ranked it as the most important species. When the insecticidal properties of bacteria were examined, they were determined as 53, 90, 62, 95, 74 and 83% for GV1, GV3, GV4, GV5, GV6 and GV7, respectively. Conclusion Based on these results and literature review, Lysinibacillus sp. species had a high potential to be used as bioinsecticide against V. destructor mite.
