INTRODUCTION: Knowledge concerning the fauna of Culicidae in the Brazilian Amazon States contributes to current understanding of the bionomics of the insects collected and makes it possible to observe changes in the fauna over time. METHODS: The Culicidae were captured with a BG-Sentinel® trap in extra-domiciliary area of two rural regions of Porto Velho in June and July of 2007 and 2008. RESULTS: A total of 10,695 Culicidae was collected, belonging to nine genera: Coquillettidia, Culex, Mansonia, Psorophora, Aedes, Aedeomyia, Anopheles, Uranotaenia and Wyeomyia. CONCLUSIONS: The presence of Mansonia (Mansonia) flaveola was recorded in the State of Rondônia for the first time.

A new species of Cladochaeta Coquillett (Diptera: Drosophilidae) is described, C. caxiuana sp. nov. from the Brazilian Amazon, based on 10 male and 10 female specimens obtained from nymphs of Sphodroscarta trivirgata (Amyot & Serville, 1843) (Hemiptera: Auchenorrhyncha: Aphrophoridae). The female of Cladochaeta atlantica Pirani & Amorim, 2016 is described based on specimens reared from spider egg sacs of the spider Cryptachaea migrans (Keyserling, 1884) (Araneae: Theridiidae) obtained in the state of Espírito Santo, Brazil. This is the first record of this fly genus attacking a spider egg sac. The species Cladochaeta sororia (Williston, 1896) is recorded for the first time from Brazil, based on specimens collected in an urban garden in the Amazon. In addition, an unidentified female specimen of Cladochaeta Coquillett, 1900 was obtained from the cocoon of a spider wasp of the genus Notocyphus Smith (Hymenoptera: Pompilidae).

The orchid-bee fauna of the region of Porto Velho, in the state of Rondônia, Brazil, close to the southernmost limits of the Amazon Basin, was surveyed for the first time using five different scents as baits to attract orchid-bee males. Five hundred and twenty-one males belonging to five genera and 29 species were collected with bait traps during 26 non-consecutive days from November, 2011 to January, 2012. Eulaema nigrita Lepeletier, 1841 and Eulaema meriana (Olivier, 1789) were the most common species in the region and, together, represented almost 50% of all collected bees. Although the observed richness conforms to similar inventories in the region, the diversity (H′= 2.43) found in the present study is one of the highest ever recorded for orchid bees in the Amazon Basin.

There are only a few published bat surveys from the southwestern Brazilian Amazon, but recent studies have reported additional bats species in the region. We provide the first list of bat species from Floresta Estadual do Antimary (Antimary State Forest) and record for the first time Glyphonycteris sylvestris Thomas, 1896 and Phylloderma stenops Peters, 1865 in the state of Acre, increasing to 64 the number of species known from this state. Our survey enlarges the known geographic range of G. sylvestris in Brazilian territory and improves the inventory of bat species in a poorly sampled region of the Amazon.

Abstract: We report range extensions for three species of Amazonian erethizontids, Coendou bicolor, C. ichillus, and C. nycthemera. We record C. ichillus for the first time in Brazil, from Rio Japurá, state of Amazonas. We record C. bicolor for the first time in the state of Amazonas, which represents a range extension of approximately 905 km. We also extend the occurrence of C. nycthemera 620 km to the south into Mato Grosso state. All records are based on museum specimens, highlighting the importance of scientific collections as biodiversity databases and emphasizing the lack of research on Amazonian porcupines.

Diagnoses and illustrations are given for Tonnoira bitalea Quate. This species is recorded from Brazil for the first time based on material collected from the state of Amazonas, Ipixuna, Rio Gregório. T. spina sp. nov. and T. tripenis sp. nov. are described and illustrated based on specimens collected from the same locality.

In this paper we describe and illustrate for the first time the immature forms (larva and pupa) of Ora semibrunnea Pic, 1922, including biological information and behavior observed in the laboratory. This is the first record of the occurrence of this species in the Brazilian Amazon region. Larvae and pupae were found in natural lakes associated with macrophyte banks. Pupae are aquatic and have morphological adaptations (well-developed pronotal siphons) to obtain atmospheric O2 at the water surface.

The present study reports the occurrence of Parakosa flexipes (Pinichpongse) (Chirodiscidae) for the first time in Brazil, along with its infection sites on Molossus rufus E. Geoffroy. Thirty-eight bats were caught using mist nets that were placed near a house at the Mars Center for Cocoa Science in the state of Bahia, of which 14 (37%) were parasitized by P. flexipes. Parakosa flexipes was observed parasitizing M. rufus on hairs that were evidently longer than others distributed over the bat's body, where up to three parasites could be spotted on a single hair.

Community viral load is an aggregate measure of HIV viral load in a particular geographic location, community, or subgroup. Community viral load provides a measure of disease burden in a community and community transmission risk. This study aims to examine community viral load trend in South Carolina and identify differences in community viral load trends between selected population subgroups using a state-wide surveillance dataset that maintains electronic records of all HIV viral load measurements reported to the state health department. Community viral load trends were examined using random mixed effects models, adjusting for age, race, gender, residence, CD4 counts, HIV risk group, and initial antiretroviral regimen during the study period, and time. The community viral load gradually decreased from 2004 to 2013 ( p < 0.0001). The number of new infections also decreased ( p = 0.0001) over time. A faster rate of decrease was seen among men compared to women ( p < 0.0001), men who have sex with men ( p = 0.0001) compared to heterosexuals, patients diagnosed in urban areas compared to that in rural areas ( p = 0.0004), and patients prescribed single-tablet regimen compared to multiple-tablet regimen ( p < 0.0001). While the state-wide community viral load decreased over time, the decline was not uniform among residence at diagnosis, HIV risk group, and single-tablet regimen versus multiple-tablet regimen subgroups. Slower declines in community viral load among females, those in rural areas, and heterosexuals suggest possible disparities in care that require further exploration. The association between using single-tablet regimen and faster community viral load decline is noteworthy.

Top of the food chain predators are often not predated upon. However, even though the giant otter (Pteronura brasiliensis) is in that category, the literature mentions many species as potential predators, including the jaguar (Panthera onca). Notwithstanding up until now there has been no registered confirmation of jaguar predation on giant otters. A predation of a jaguar on an adult female giant otter was recorded for the first time during our radio-telemetry study on giant otters in Balbina hydroelectric reservoir in Central Brazilian Amazon. The female had had a transmitter implanted on February 2012 and was killed by a jaguar ninety-four days after the surgery. This giant otter was a solitary specimen, which was captured by a jaguar while asleep in a shelter under a fallen tree trunk on the banks of one of the reservoir’s islands. The solitary pattern found in such individuals combined with the frequent use of shelters, allows predators to access them more easily and may have contributed to the predation observed in this study.

Fifteen insect gall morphotypes were found on 11 plant species (8 families) in three fragments of the Dense Ombrophylous Lowland Forest, in the municipalities of Maracajá, Içara and Araranguá, Santa Catarina. Most of the galls occurred in leaves, followed by stems galls and a single gall morphotype in Leandra sp. (Melatomastaceae), occurred in both leaves and stems. Glabrous and isolated galls were more frequent than hairy and gregarious galls. Lauraceae was the family of plant with greater wealth of galls. It was pointed out the first record of the plant Microstachys serrulata (Euphorbiaceae) for the state of Santa Catarina. Galls found in Ilex theezans (Aquifoliaceae), Microstachys serrulata (Euphorbiaceae), Dahlstedtia muehlbergiana (Fabaceae), Nectandra oppositifolia (Lauraceae), Leandra sp. (Melastomataceae), Miconia sellowiana (Melastomataceae), Myrcia multiflora (Myrtaceae) and Urera nitida (Urticaceae) were recorded for the first time in the State of Santa Catarina.
