Insect transmission of the bacterial ring rot pathogen
Abstract
Three species of potato-infesting insects were evaluated under laboratory and field conditions for their capability to transmit Corynebacterium sepedonicum (Spieck. & Kotth.) Skapt. & Burkh., the bacterial ring rot (BRR) pathogen of potatoes. Laboratory and field studies confirmed the vector capability of the Colorado potato beetle (CPB), Leptinotarsa decemlineata (Say) (Coleoptera: Chrysomelidae) and the green peach aphid (GPA), Myzus persicae (Sulzer) (Homoptera: Aphididae). Both adults and larvae of the CPB proved to be vectors of the pathogen. Only adult GPA were evaluated. Bacterial transmission was most likely mechanical: analyses of the CPB mouthparts stained by the indirect immunofluorescence antibody staining (IFAS) procedure confirmed the presence of the bacterium after the beetles were exposed to infected plant tissue. Eggs, haemolymph, feces, regurgitations, and macerates of the digestive tract failed to show the presence of the bacterium. The aster leafhopper, Macrosteles fascifrons (St∮al) (Homoptera: Cicadellidae) failed to acquire and transmit Corynebacterium sepedonicum. © 1991 Springer.
