Efeito da estrutura de habitat sobre a abundância de parasitóides Pseudacteon Coquillett (Diptera, Phoridae) em ninhos de Solenopsis invicta Buren (Hymenoptera, Formicidae)

“…A formiga lava-pé Solenopsis invicta Buren (Hymenoptera: Formicidae) é uma espécie nativa da América do Sul que ocorre também nas Américas Central e do Norte, Ásia e Oceania (Callcott & Collins 1996;Holway et al 2002;Zhang et al 2007).

Positive-Strand RNA Viruses Infecting the Red Imported Fire Ant,Solenopsis invicta

“…S. invicta has clearly emerged as the most successful of the two ant species, largely displacing and relegating S. richteri to a roughly contiguous area in eastern Mississippi, western Alabama, and western Tennessee [2]. In contrast, since its introduction, S. invicta has expanded its range to infest more than 138 million hectares ( Figure 1) from Virginia, south to Florida, and west to California [3]. Although both of these fire ant species are invasive, S. invicta is by far the most successful and considered the major pest species in the USA.…”

Consuming Fire Ants Reduces Northern Bobwhite Survival and Weight Gain1

“…Fire ants were introduced accidentally into the United States in the 1930s through the port of Mobile, Alabama (Wilson 1951, Williams et al 2001, and they spread rapidly throughout the southeastern USA (Callcott & Collins 1996) and then to New Mexico, Arizona, and California (Williams et al 2001). Fire ants have been introduced to other areas of the earth as well, including Australia (Shattuck & Barnett 2005), the Caribbean, and Asia (Ascunce et al 2011).…”
