Sympatry of Polygyne and Monogyne Colonies of the Fire Ant Solenopsis invicta (Hymenoptera: Formicidae)
The polygyne form of the red imported Þre ant, Solenopsis invicta Buren, is thought to occur primarily in discrete populations embeddedwithin areas composed ofmonogyne colonies. This distribution implies that polygyne colonies competewithmonogyne colonies and subsequently create a population homogenous in social form. Because polygyne colonies produce mostly sterile males, opportunities for ins...

متن کاملPopulation Genetics of the Invasive Fire Ant Solenopsis invicta (Hymenoptera: Formicidae) in the United States
Analyses of population genetic variation in invasive species can provide information on the history of the invasions, breeding systems, and gene ßow patterns. We surveyed genetic variation in both social forms of the red imported Þre ant, Solenopsis invictaBuren (Hymenoptera: Formicidae), throughout the speciesÕ introduced range in the United States, to learn how the unique breeding biology of ...
متن کاملSampling efficacy for the red imported fire ant Solenopsis invicta (Hymenoptera: Formicidae).
Cost-effective detection of invasive ant colonies before establishment in new ranges is imperative for the protection of national borders and reducing their global impact. We examined the sampling efficiency of food-baits and pitfall traps (baited and nonbaited) in detecting isolated red imported fire ant (Solenopsis invicta Buren) nests in multiple environments in Gainesville, FL. Fire ants d...

Alate trapping studies of a monogyne population of the fire ant Solenopsis geminata indicate that two sizes of gynes are produced. Macrogynes, which participate in late spring and summer mating flights, are larger, fattier, and more than twice as heavy as microgynes, which participate in fall mating flights. Three patterns of gyne production were observed in 51 colonies studied: 35 produced mac...
