Observations on a parasitic nematode (Tetradonematidae) of fire ants, solenopsis (Formicidae), from Mato Grosso.
Parasitic nematodes, Tetradonema sp. (Mermithoidea: Tetradonematidae) were obwserved in the fire ant. Solenopsis invicta Buren, for the first time. Five colonies in a sample of 14 colonies from one site in Mato Grosso were infected. The infection rate among adult workers was 12..5% in one colony and less than 5% in each of the remaining colonies. Adult reproductive males and females, eggs, and juvenile nematodes were observed in the haemocoel of male and worker ants. The infected worker ants often can be recognized by their slightly enlarged gasters, the dorsal scierites of which vable changes in behavior: infected adult males contained normal sperm. An attempt to transmit the nematode to colonies of S. invicta in the United States was unsuccessful.
