Abstract

Eight spiroplasma strains from insects and one from spring flowers failed to react with antisera specific for any of the 11 described spiroplasma groups, with sera directed against spiroplasma Group I subgroups, or with sera directed against two unnumbered groups previously reported to occur in tabanid flies. Strains, all from Maryland, were isolated from the hemolymph of the spotted cucumber beetle Diabrotica undecimpunctata and the lampyrid beetle Ellychnia corrusca, and the guts of the cantharid beetles Cantharis bilineatus and C. carolinus. Other strains were obtained from a tabanid fly, Tabanus gladiator and from the firefly Photuris pennsylvanica in Maryland and from the mosquito Culex tritaeniorhynchus in Taiwan. An isolate from pooled Cicadulina bipunctella leafhoppers in Syria apparently represented a unique group. A single isolate from spring flowers in Oklahoma also appeared to be unrelated to existing groups or subgroups. One-way deformation tests using sera prepared against known beetle and tabanid spiroplasmas showed each of the above strains to be unique. Although these results strongly indicate that the nine strains studied are representatives of unique new spiroplasma groups, the formal designation of new groups awaits fulfillment of recently proposed criteria.
