Interpretive Summary: Anastrepha suspensa is an economically important pest, which is restricted to the Greater Antilles and southern Florida (the known distribution of A. suspensa). A. suspensa infests a wide variety of hosts including citrus, a multi-million dollar industry in Florida. The recent increase in observance of citrus infested with A. suspensa in Florida has raised questions regarding host-specificity of certain populations and genetic diversity of the pest throughout its geographic distribution. Two different types of genetic data have been gathered and analyzed. One type of genetic data shows no genetic differences between Carib flies from Florida and the Caribbean. However, the second type of genetic data shows genetic differences within and between populations from Florida, Puerto Rico, Jamaica, Dominican Republic, and the Cayman Islands was observed. This information is being used to characterize the genetic diversity of A. suspensa within multiple Florida populations taken from different host plants and from different geographical regions.

Technical Abstract: Anastrepha suspensa is an economically important pest, which is restricted to the Greater Antilles and southern Florida (the known distribution of A. suspensa). A. suspensa infests a wide variety of hosts including citrus, a multi-million dollar industry in Florida. The recent increase in observance of citrus infested with A. suspensa in Florida has raised questions regarding host-specificity of certain populations and genetic diversity of the pest throughout its geographic distribution. Phylogenetic analyses of the mitochondrial COI gene from A. suspensa collected at different geographical locations throughout Florida and the Caribbean show similar sequence diversity within and among all populations. However, using eight microsatellite loci, preliminary data show allelic diversity within and between populations from Florida, Puerto Rico, Jamaica, Dominican Republic, and the Cayman Islands was observed. This information is being used to characterize the genetic diversity of A. suspensa within multiple Florida populations taken from different host plants and from different geographical regions.
