“…The reasons for this discrepancy are unclear, however, the modest signs of ecological impact found here, particularly among native species, may simply be a consequence of the relatively low densities of ants that occurred in this system, rather than an indication of behavioral differences with other invasive ant species. For instance, the sensitivity of some native Lepidoptera to even relatively low densities of ants in this study matches reports of lepidopteran vulnerability to other invasive ant species, such as L. humile (Cole et al 1992;Abril et al 2007;Rowles and O'Dowd 2009;EstanyTigerstrom et al 2010;Krushelnycky and Gillespie 2010), S. invicta (Eubanks 2001;Vogt et al 2001), S. geminata (Way et al 1998), A. gracilipes (Holway et al 2002) and P. megacephala (Bach 1991). Such similarities could support the hypothesis that tramp ant species may not differ substantially from some of the better-studied invasive ants in the nature of their interactions with other arthropods, and that the ecological impacts of many introduced ant species may largely be a function of their density.…”

Invasive ants can have strong ecological effects on native arthropods, but most information on this topic comes from studies of a handful of ant species. The ecological impacts of the many additional introduced 'tramp' ant species are largely unknown. In mesic upland forests of O'ahu, Hawai'i, ten species of introduced ants were found on four species of understory trees. However, these ants were generally uncommon and occurred at relatively low densities in this habitat type. The most common and abundant ant was Plagiolepis alluaudi, which favored the native tree Pipturus albidus. Ecological effects of ants on arthropods were found to be modest, with overall arthropod community composition not significantly different between ant-occupied and ant-free trees. Most taxonomic groups were similar in abundance and richness between ant-occupied and ant-free trees, except adventive Coleoptera, adventive Hemiptera, and Lepidoptera were less abundant on ant-occupied trees, and adventive Coleoptera and adventive Hemiptera also had lower richness on ant-occupied trees. Among Lepidoptera, caterpillars of two endemic groups had significantly lower incidences on trees with higher ant abundances, while other caterpillars did not. Arthropod trophic structure was largely unaffected, except that chewing herbivores comprised a smaller fraction of biomass on ant-occupied trees. While overall ecological effects were weak in comparison to prior results involving other ant species in Hawai'i, some of the impacts suggest that higher densities of these introduced ant species could result in similar interactions with arthropods as those of the better-studied invasive ant species.

“…In cowpea, S. invicta reduced egg densities of Leptoglossus phyllopus (L.) (Abudulai et al 2001) and preyed on pupae of cowpea curculio, Chalcodermus aeneus Boheman (Russell 1981). In peanuts, Vogt et al (2001) found that most S. invicta food items were rednecked pea-nutworms, Stegasta bosqueella Chambers. S. invicta in sugarcane is recognized as a controlling agent of sugarcane borer, and its presence is promoted through conservation practices (Adams et al 1981, Fuller and Reagan 1988, Bessin and Reagan 1993.…”

The effects of the red imported fire ant, Solenopsis invicta Buren (Hymenoptera: Formicidae), on cotton aphid, Aphis gossypii Glover, populations and its predation of bollworm, Helicoverpa zea (Boddie), and beet armyworm, Spodoptera exigua (Hübner), (both Lepidoptera: Noctuidae) eggs were evaluated in cotton under field conditions during 2001 and 2002 in central and northern Texas. In central Texas, cotton aphid populations were approximately 5.5 times greater and predation of sentinel bollworm eggs 2 times greater in the presence of S. invicta versus in its absence, although aphid populations did not reach economic levels. Most predation of beet armyworm egg masses, measured via direct nocturnal observations, was due to S. invicta (68%) and cotton fleahopper, Pseudatomoscelis seriatus (Reuter) (21%), where S. invicta was present, and by the mite Abrolophus sp. (52%), spiders (13%), and minute pirate bug (Orius sp.) (13%) where S. invicta was absent. Predation of sentinel bollworm eggs and beet armyworm egg masses was approximately 1.5 and 4.1 times greater, respectively, in the presence of S. invicta versus in their absence. In the presence of S. invicta, the relative frequencies of minute pirate bug and cotton fleahopper were higher, and of S. invicta and native ants lower in beat bucket samples compared with their relative frequencies in nocturnal observations of predation upon beet armyworm egg masses. In the absence of S. invicta seven of eight predators sampled were similarly represented in beat bucket samples and nocturnal observations of beet armyworm egg mass predation, whereas minute pirate bug occurred at a higher frequency in beat bucket samples relative to nocturnal observations. These observations suggested that the relative frequencies of minute pirate bug, cotton fleahopper, S. invicta and native ants in beat bucket samples do not closely reflect the frequency with which these predators prey on noctuid eggs. Overall, the results of this study show that although S. invicta may promote aphid populations early in the growing season, it is an important predator of bollworm and beet armyworm eggs later in the season.

“…Os custos estimados para o controle de S. invicta em pomares no estado da Califórnia, EUA, variam Efeito da estrutura de habitat sobre a abundância de parasitóides Pseudacteon Coquillett (Diptera, Phoridae) em ninhos de Solenopsis invicta Buren (Hymenoptera, Formicidae) de 12 a 48 milhões de dólares anuais (Jetter et al 2002). Por outro lado, S. invicta pode apresentar efeitos benéficos para plantas cultivadas através da predação de insetos praga (Eubanks 2001;Vogt et al 2001). Embora o controle químico de S. invicta venha sendo o mais utilizado, sugere-se que o desenvolvimento de técnicas com diferentes táticas de controle seja importante para o manejo integrado desta espécie (Williams et al 2001).…”
