Investigations on the microflora of the scale insects Aspidiotus nerii Bouchй, 1833, Chrysomphalus aonidum Linnaeus, 1758 and Icerya purchasi Maskell, 1879 were performed to estimate their role as vectors of pathogenic bacteria and fungi. Bacillus spp., Clostridium spp., Candida tropicalis and Aspergillus sp. were isolated from A. nerii and C. aonidum. Besides these microorganisms at A. nerii were established Enterobacter agglomerans, while at C. aonidum - Pseudomonas cichorii and Listeria innocua. Enthomopathogenic fungi were also settled: Nectria aurantiicola Berk. and Br. Fusarium larvarum Fuckel from A. nerii and Podonectria coccicola Ell. and Ev. Petch from C. aonidum. The bacteria isolated from I. purchasi refer to the following groups: family Enterobacteriaceae E. coli, Enterobacter agglomerans, Erwinia amylovora and genera Pseudomonas P. diminuta, Listeria and Clostridium. The established fungi were from the genera Candida and Aspergillus. The results from the investigations show that these scales can be carriers and distributors of causal agents of dangerous infections in plants E. amylovora, P. cichorii, as well as of mycoses in these and other insects from the genera Nectria and Podonectria, but also of E. coli and microorganisms from the genera Enterobacter, Candida and Aspergillus with pathogenic properties for animals and humans. A symbiosis of the species I. purchasi with the bacterium Pseudomonas diminuta, which degrades organophosphate insecticides, was established too, making it resistant to lice preparations for chemical control.
