Ecosystems & Species
Entomopathogenic Nematodes (Nematoda: Rhabditida: families Steinernematidae and Heterorhabditidae) (EENY530/IN944)
Entomopathogenic nematodes are soft bodied, non-segmented roundworms that are obligate or sometimes facultative parasites of insects. They occur naturally in soil environments and locate their host in response to carbon dioxide, vibration, and other chemical cues. They fit nicely into integrated pest management programs because they are nontoxic to humans, specific to their target pests, and can be applied with standard pesticide equipment. This 4-page fact sheet was written by Nastaran Tofangsazie, Steven P. Arthurs, and Robin M. Giblin-Davis, and published by the UF Department of Entomology and Nematology, August 2012.
Common Monogenean Parasites of Fishes (FA28/FA033)
Monogeneans are a class of parasitic flatworms that are commonly found on fishes and lower aquatic invertebrates. Most monogeneans are browsers that move about freely on the fish’s body surface feeding on mucus and epithelial cells of the skin and gills; however, a few adult monogeneans will remain permanently attached to a single site on the host. Some monogenean species invade the rectal cavity, ureter, body cavity, and even the blood vascular system. Between 4,000 and 5,000 species of monogeneans have been described. They are found on fishes in fresh and salt water and in a wide range of water temperatures. This 10-page fact sheet was written by Peggy Reed, Ruth Francis-Floyd, and RuthEllen Klinger, and published by the UF Department of Fisheries and Aquatic Sciences, June 2012.
