New Pseudacteon (Diptera: Phoridae) from North America that parasitizes the native fire ant
Solenopsis geminate/ (Hymenoptera: Formicidae).
The non-indigenous ant,
Solenopsis invicta, reduces loggerhead shrike and native insect abundance, J.
However, the high total abundances were largely influenced by ants with opportunistic behaviour, such as
Solenopsis invicta (Myrmicinae), with 1,339 individuals and present in all "veredas".

The cotton mealybug, Phenacoccus
solenopsis Tinsley (Hemiptera: Pseudococcidae), a native of North America (Williams and Granara de Willink, 1992), is distributed over a wide range of agro-ecological zones in at least 24 countries (Wang et al., 2009).
However, the forest sites also indicate the dominance of two species,
Solenopsis sp.
(Characterization of 24 microsatellite markers in 11 species of fire ants in the genus
Solenopsis (Hymenoptera: Formicidae).
Defensive chemicals of tawny crazy ants, Nylanderia fulva (Hymenoptera: Formicidae) and their toxicity to red imported fre ants,
Solenopsis invicta (Hymenoptera: Formicidae).
"One species we looked at, the thief ant (
Solenopsis molesta), had the most powerful antibiotic effect of any species we tested - and until now, no one had even shown that they made use of antimicrobials," said Adrian Smith, co-author of the paper.
Contrairement a leurs attentes, les chercheurs ont constate que les plus grosses colonies et les plus grandes fourmis, des ouvrieres, n'ont pas fait montre d'une production d'antimicrobiens plus puissants ou en plus grandes quantites, selon l'article dans lequel il est note que "deux des especes qui ont demontre la plus forte activite antimicrobienne font partie des plus petites fourmis testees (noms savants : Monomorium minimum et
Solenopsis molesta)".
