Urbanization is one of the most important threats for biodiversity. Among many different organisms, butterflies are useful indicators of environment diversity and quality. The aim of this study was to investigate the Lepidoptera from Corrientes city. Random samplings were performed at two sites: a native forest situated in Santa Catalina district and an urban area, Parque Mitre. The captures were carried out using entomological nets, at four seasons between January to October 2007. A total of 1 114 butterflies, represented by six families: Hesperiidae, Lycaenidae, Nymphalidae, Papilionidae, Pieridae and Riodinidae and 18 subfamilies were recorded. Fifty-nine genera and 75 species were identified; Anartia jatrophae jatrophae was the most abundant species at both localities. This species and Urbanus procne, Phoebis sennae marcellina, Pyrgus orcus and Dryas iulia alcionea were, among other seven, captured at all months. Highest values of abundance were registered during the warmest seasons. Santa Catalina presented the largest abundance (n=701), richness (S=74) and diversity (H'=3.87). A total of 413 individuals and 52 species were identified at Parque Mitre, and Shannon diversity index was 3.58. The obtained data reveals a high species richness and similarity at both sites.

Pitfall traps baited with carrion and cattle dung were left open for 72-hour periods in October, November and December 2006. 769 adults belonging to six tribes, 11 genera and 26 species were captured in all. At Los Alisos, Ontherus sulcatus Fabricius and Onthophagus hirculus Mannerheim were the dominant species. Trichillum sp., Canthon podagricus Harold, Malagoniella sp., Gromphas lacordairei Brullé, and two Dichotomius Hope species were only found at Los Alisos, whereas Canthon septemmaculatus Latreille and Coprophanaeus jasius Olivier were exclusively collected in Pampa del Indio. Number of individuals and diversity were significantly higher at Pampa del Indio. The same proportions of coprophagous and necrophagous species were captured at Los Alisos, with most having endocoprid and paracoprid habits. Pampa del Indio was characterized by the presence of rollers and necrophagous species. This research is the first study of forest Scarabaeinae biodiversity in Chaco province.

The aim of this study was to estimate potential suitable areas for C. phyllopus to provide further knowledge on its current distribution. A dataset of 43 records was compiled and species distribution modelling was employed linking these occurrences with bioclimatic variables. Results indicate higher suitability conditions along the Atlantic coast of Brazil, reaching north Uruguay and extending inland to Paraguay and northern parts of Argentina. In addition, we report a new distributional record from Corrientes, Argentina.

The greatest species diversity was recorded in the grassland with intensive livestock grazing and predominance of native plant species, whereas the abundance values were higher in the grassland without grazing and characterized by introduced plant species. In total, 25 Orthoptera species were collected during the study. Acrididae (Caelifera) was the most abundant and diverse family recorded. Staurorhectus longicornis, Dichromorpha australis and Orphulella punctata were the most abundant species; the last two species being recorded during the entire sampling period. The greatest abundance was recorded in December 2006. Abundance did not show any correlation with climatic variables.

Samplings were performed in 2007 and 2008 in randomly selected households at rural areas. Diagnosis of Chagas infection in volunteer residents was performed using indirect hemagglutination, indirect immunofluorescence and indirect immunoen-zimatic assay. Thirty human dwellings and 25 peridomestic ecotopes were searched at Berón de Astrada, and 32 houses and 33 peridomiciles at Mburucuyá. A total of 19 nymphs were captured in a chicken coop at Mburucuyá, the infestation rate was 3.0%. At Berón de Astrada 4.0% of the peridomiciles resulted infested by Triatoma sordida, a female and 58 eggs were collected in a hen nest. Trypanosoma cruzi infection was not detected in Triatoma sordida. The prevalence human rate was 5.2% (11/77) at Mburucuyá and 14.3% (4/77) at Berón de Astrada. Presence of triatomines was not confirmed at the human dwellings, and the infestation of the peridomestic structures was low. It is necessary to implement new strategies of vectorial control, especially for those species that prevail in the peridomicile and sylvatic ecotopes. Seroprevalence was lower that the observed in previous investigations in other rural areas of Corrientes. The absence of seroreactives in the 0-10 age group suggests a halt in T. cruzi transmission in the studied area.

Samplings were performed in spring 1998 and summer 1999 in Colonia Laurel, Department San Roque, Corrientes, Argentina. Timed-collection of triatomines (man/hour method) was performed. Trypanosoma cruzi identity was determined by morphological criteria and by PCR. Indirect hemagglutination and indirect immunofluorescence antibody tests were used for detection of T. cruzi infection in human volunteers. Sixteen human dwellings were analized, 11 resulted infested by Triatoma infestans and two by Triatoma sordida. A total of 122 T. infestans of all age classes were collected and T. cruzi infection was recorded in 16.7%. Triatoma infestans was confirmed as the predominant species in the domicile and T. sordida in the peridomicile. Diagnosis of Chagas disease infection was performed in 77.9% (88/113) of the inhabitants and the prevalence was 26.1%. A relatively high infection rate was observed in the 0-10 age group. Seropositives percentages increased with age and reached 66.6% in older than 40 years. Presence of T. infestans, human seroreactivity to T. cruzi, < or = 4 year old seropositives and precarious life conditions prove that this endemic disease is still a problem in the studied area.

In this study, we evaluated changes in abundance, species richness, and diversity of flesh flies in different habitat types in the Humid Chaco ecoregion of South America: 1) anthropized habitats: urban, cattle farm, and alfalfa crop, and 2) natural habitats: savanna and forest. We hypothesized that sarcophagid fly community parameters are affected by the anthropization and that spatial turnover will contribute more to the overall beta diversity than nestedness between habitats. In each habitat, samplings were conducted monthly from March 2015 to February 2016 in 25 sites, 5 per habitat, totaling 300 independent samples at the end of the study. We collected 5,790 Sarcophagidae (55 species). Community parameters of Sarcophagidae were evaluated and compared. The ecological effects of anthropization and habitat type were observed in the present study. As expected, our results showed the highest abundance, species richness, and diversity in the savanna and forest habitats (natural), whereas the lowest values were registered in the urban and alfalfa crop habitats, supporting the hypotheses of anthropization as the main driver of diversity loss. In addition, sarcophagid assemblages differed between all habitats and the overall dissimilarity was structured by spatial turnover. The main conclusion of this research is that flesh fly community structure is greatly affected by anthropization and habitat type, and this would be related to canopy cover and microclimate conditions of each environment.

The flies were collected at 18 sampling points, three per site. In total, 3,318 flies were collected (3,077 blow flies and 241 flesh flies), distributed in 13 genera and 33 species. Calliphoridae was the most abundant, comprised 92.74% of all adult flies. Chrysomya albiceps (Wiedemann), Cochliomyia macellaria (F.), Chrysomya megacephala (F.), and Chrysomya putoria (Wiedemann) were the most abundant species, representing 82.21% of the total sample. The genus Oxysarcodexia Townsend was the most diverse with 10 species represented. The abundance of exotic species represents 62.85% of the total sample, showing a reduction toward less disturbed sites. The results of this study indicated that sites with intermediate impact had higher diversity than those where the disturbances are high or absent. Our findings provide the first assessment of Calliphoridae and Sarcophagidae diversity in the area of the Iber a Wetlands.

The effects of habitat heterogeneity (vegetation cover) on terrestrial ant (Formicidae) assemblages were analyzed and compared. The habitat heterogeneity hypothesis—which predicts that when environmental structural complexity increases, the species richness will also increase—was tested. Two sites were selected in each ecoregion. A forest and a grassland were surveyed in each site, using unbaited pitfall traps from October 2013 to February 2014. Overall, 5,465 ants belonging to 37 species were collected, 32 of which were present in forests and 26 in grasslands. Solenopsis invicta Buren (Hymenoptera: Formicidae) and Pheidole radoszkowskii Mayr (Hymenoptera: Formicidae) were the most abundant species.
