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.

Furuncular Myiasis

Abstract Two individuals of the jaguar, Panthera onca (L.), were captured near the municipality of Presidente Figueiredo, Brazilian Amazon, during the years of 2017 and 2018. The jaguars presented furuncular myiasis caused by the human botfly Dermatobia hominis (L.) on the rear thighs and tail. This is the first record of infestation of D. hominis in P. onca in the Amazon region.

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.

A New Species

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).

ABSTRACT The southern lapwing, Vanellus chilensis, is a bird frequently seen in most of Brazil. Although it is widely distributed in other Brazilian biomes, including some parts of the Brazilian Amazon, it has only been recorded in the western Amazonian state of Acre since 2000. We report the presence of intestinal parasites in individuals of V. chilensis from the Cazumbá-Iracema Extractive Reserve in Acre through a coproparasitological analysis. Seven of the nine sampled individuals were parasitized. We observed larvae of Strongyloides sp. (28.5% of the samples), and eggs of Ascaridia sp. (28.5%), Ancylostoma sp. (14.2%), and Choanotaenia sp. (42.8%). These parasites are reported for the first time parasitizing V. chilensis in Brazil. The parasitized birds may act as reservoirs and were recorded in a peridomicile area, which may facilitate their contact with domestic birds.

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.

Abstract The weevil of acerola fruits, Anthonomus tomentosus (Faust, 1894) (Coleoptera: Curculionidae), is recorded for the first time in Brazil. Samples of this insect were collected in fruits of acerola, Malpighia emarginata D.C. (Malpighiaceae), in four municipalities in the north-central region of Roraima State, in the Brazilian Amazon. Information about injuries observed in fruits infested with A. tomentosus, its distribution in Roraima, and suggestions for pest management are presented.
