AbstractParasitism by Pollenia rudis (Fabr.) larvae on earthworms in the field was found only in Allolobophora chlorotica (Sav.) and Eisenia rosea (Sav.). Other species of worms were infected in the laboratory. Slime and coelomic fluid, from all species of worms tested, induced penetration behaviour. Penetration occurs mainly on the dorsal surface of the worm, and less frequently towards either end. Larvae repenetrated after leaving the original penetration site. Autonomy by the host of the parasitized segments was observed in E. rosea. Possible reasons for the restricted natural host range are discussed.

This study completes Koch's postulates for P. hibernalis on rhododendron. P. hibernalis has previously been described as causing brown rot of citrus. This report expands the pathogen's known natural host range. P. hibernalis does not appear to be widespread in the California and Oregon nursery industries, but was recovered in both states for three consecutive years. Accepted for publication 8 July 2005. Published 28 July 2005.

Pucciniamodiolae, a rust fungus pathogen of Carolina bristlemallow, Modiolacaroliniana (Malvaceae), is newly reported from North America, appears to be well established along the Gulf coast and is likely to have been introduced from South America. Its taxonomy, distribution and natural host range are discussed and a lectotype designated for this species. Malvasylvestris and Alcearosea are reported as new hosts for the rust. Additional new records for Malvaceae rusts are made for P.modiolae on Alcearosea from Brazil, P.heterospora on Herissantiacrispa in Florida and P.heterogenea on Malva sp. in Peru. Finally, an identification key for the microcyclic Puccinia species on members of Malvaceae in North America is provided.
