“…Similar to the Solenopsis invicta Buren, 1972 species in the south region of the United States, when introduced in other regions, the fire ants can cause serious structural, ecological and public health problems (Tschinkel, 2006). Several fly species of the genus Pseudacteon (Diptera: Phoridae) and Orasema xanthopus (Cameron, 1909) (Hymenoptera: Eucharitidae) are known parasitoids of S. saevissima (Pesquero & Dias, 2004, 2011, and the discovery of this new spider species expands the number of natural enemies with potential use in biological control programs.…”

Myrmecophily and Myrmecophagy of Attacobius lavape (Araneae: Corinnidae) on Solenopsis saevissima (Hymenoptera: Myrmicinae)

Attacobius lavape, a small spider from the Corinnidae family, has been recently described living inside a fire ant colony of Solenopsis saevissima species in the municipality of Morrinhos, south region of the Goiás State, Brazil. Yet several aspects of this spider relationship with the host ant remain unknown. In this way, we performed an extension study to determine its local (Morrinhos) and regional (latitudinal transect) occurrence. We also investigated if the spider uses the host ant as a feeding source. For this, we established arenas with a known number of young and adult ant individuals plus one spider and observed the feeding rate for some determined time. Regarding local distribution, differently from most socially parasitic myrmecophiles, A. lavape showed high local infestation, being found in 47% of the colonies in the sites where the spider occurred, and high transmission, being found in 42% of the 12 collection sites. Regionally, among the 11 study sites, this species only occurred in the municipality of Morrinhos, but its distribution still needs to be verified in the north region. Attacobius lavape consumed eggs, larvae and pupae, confirming that the myrmecophily was explained by myrmecophagy. The spiders consumed eggs (not estimated), 4.45 ± 2.14 larvae and/or 3 ± 0.87 pupae per day. Considering that the mean abundance was approximately seven spiders per colony (extent 1-23), we foresee an impact of 35 larvae and/or 21 pupae consumed per day in each hosting colony. The possibility of consuming sexual eggs, larvae and pupae classifies A. lavape as a potential agent of biological control of S. saevissima.

Inquiline ant social parasites exploit other ant species for their reproductive benefit because they do not possess a worker caste. Due to their relative rarity in nature, the biology and natural history of inquilines are largely unknown. Likewise, not much research exists that details the close relationship between inquilines and their host(s), and how each organism influences the genetic structure of the other. Here, we conducted a comparative population genetics study to assess patterns of genetic structure within and among populations of inquiline Solenopsis daguerrei and its known fire ant hosts, which includes invasive Solenopsis invicta. Using nuclear and mitochondrial markers, we show that four genetically distinct groups of S. daguerrei likely exist, each with different degrees of host association. Consistent with previous inferences of the inquiline lifestyle, we find that inbreeding is common in S. daguerrei, presumably a result of intranidal mating and restricted dispersal. Results from this study, specifically host association patterns, may inform future biological control strategies to mitigate invasive S. invicta populations.
