| evolutionary avenues for, and constraints on, the transmission of frog lung flukes (haematoloechus spp.) in dragonfly second intermediate hosts. | metacercariae survival patterns and their distribution in second intermediate odonate hosts were examined for 4 species of frog lung flukes. surveys of aquatic larvae and recently emerged teneral dragonflies and damselflies indicated that prevalence and mean abundance of haematoloechus spp. metacercariae were significantly lower in teneral dragonflies than larval dragonflies, while there was no significant difference in prevalence or mean abundance of haematoloechus spp. metacercariae among larv ... | 2007 | 17626352 |
