| Abstract/Contents: | "Florida's mole cricket project, begun in 1978, has for the last several years concentrated all its resources on biological control efforts. To date, three natural enemies of mole crickets have been released in Florida and several others are undergoing laboratory evaluation. The three currently in the field are: Larra bicolor: This wasp (family Sphecidae) was released in 1982 in several locations but became established only in the Ft. Lauderdale area. It is an external parasite of all three species of introduced mole crickets but seems to prefer the short-winged mole cricket, Scapteriscus abbreviatus. More recent efforts have dealt with Larra species (including bicolor) from more temperate regions of South America in hopes of finding one better able to cope with the climate of north Florida. Releases of two species from Bolivia were made in 1988-89. Ormia depleta: This fly (family Tachinidae) is attracted to the song of mole crickets and deposits larvae on and around calling males. Releases were made in 1988 and 1989, and the fly seems to have survived the winter in the Gainesville area. Impact on local mole cricket populations remains to be evaluated. Steinernema (=Neoaplectana) feltiae: A parasitic nematode (family Steinernematidae) with host range limited to mole crickets and related Orthoptera, S. feltiae was released in 1985 in small plot field trials. It has persisted in the release fields for 4 years and is now found over a wide area of Alachua County. Mole cricket populations in release fields have declined dramatically, and the bahiagrass pastures are recovering. This is the most promising candidate controlagent and plans for large-scale releases in turf and pasture sites around Florida are underway. The nematode is being produced by Biosys, a California company specializing in production of nematodes for biological control of insect pests." |
