ABSTRACT

Abstract: This paper covers the first record of window flies, Scenopinidae (Diptera), in the archipelago of Fernando de Noronha, Brazil: Scenopinus schulzi Enderlein, which is briefly characterized. This species was recorded in low numbers: three males and 13 female specimens. The occurrence of scenopinids in Fernando de Noronha is regarded as an extension of the Brazilian mainland continental fauna. The colonization of the archipelago is discussed.


Resumo: Este trabalho faz o primeiro registro de uma espécie de Scenopinidae no Arquipélago de Fernando de Noronha, Brasil: Scenopinus schulzi Enderlein, brevemente caracterizada. Esta espécie foi registrada em baixa densidade: três machos e 13 fêmeas. A ocorrência de scenopinideos em Fernando de Noronha é atribuída à extensão territorial da fauna continental e sua colonização no arquipélago é discutida.

ABSTRACT

Abstract: The sweat bees from Fernando de Noronha Archipelago are presented and illustrated herein. The species recorded are Augochlora (Augochlora) laevipyga (Kirby, 1890), Augochlora (Augochlora) sp., new record, and Lasioglossum (Dialictus) atripyga (Kirby, 1890).

ABSTRACT

Abstract: The seasonal population density is informed for two epidemiologically important species of bloodsucking Tabanidae, Tabanus occidentalis Linnaeus and T. pungens Wiedemann, recorded at the Fernando de Noronha archipelago that was never connected to the continent. The two species are widespread in the Neotropical Region, have not been recorded from any other oceanic island, and have most likely been introduced accidentally in the archipelago. Tabanus occidentalis dominated the samples, encompassing 99.6% of the specimens collected in the two local seasons, rainy and dry. Tabanus pungens was rarer, encompassing 0.4% of the specimens collected mainly in the dry season. The tabanids of Fernando de Noronha are able to transmit blood pathogens, bringing risks to the health of the livestock. They also pester the tourists, which brings losses to the local tourist industry. Larvae of both species were already collected in the water lettuce Pistia stratiotes Linnaeus and it is highly recommend that this introduced aquatic plant be removed from the ponds of Fernando de Noronha to control tabanid populations.


Resumo: A densidade populacional e a sazonalidade é informada para duas espécies epidemiologicamente importantes de Tabanidae, Tabanus occidentalis Linnaeus e T. pungens Wiedemann, registradas no arquipélago de Fernando de Noronha, o qual nunca foi conectado ao continente. As duas espécies estão amplamente distribuídas na Região Neotropical, não foram registradas em nenhuma outra ilha oceânica e provavelmente foram introduzidas acidentalmente no arquipélago. Tabanus occidentalis dominou as amostras, englobando 99,6% dos exemplares coletados nas duas estações locais, chuvosa e seca. Tabanus pungens foi mais rara, abrangendo 0,4% dos espécimes coletados principalmente na estação seca. Os tabanídeos de Fernando de Noronha são capazes de transmitir patógenos do sangue, trazendo riscos à saúde do gado. Eles também incomodam os turistas, o que traz prejuízos para a indústria turística local. Larvas de ambas as espécies já foram coletadas na alface d'água Pistia stratiotes Linnaeus e é altamente recomendável que esta planta aquática, introduzida no arquipélago, seja removida das lagoas de Fernando de Noronha para o controle de populações de tabanídeos.

ABSTRACT

ABSTRACT We recorded for the first time the presence of the two fruit flies pests, Anastrepha obliqua (Macquart) and Ceratitis capitata (Wiedemann) (Diptera: Tephritidae) and the parasitoid Doryctobracon areolatus (Szépligeti) (Hymenoptera: Braconidae) in the oceanic archipelago of Fernando de Noronha, Pernambuco, Brazil. The specimens were collected in traps installed during June/2019 to February/2020. The fruit flies and the parasitoid species are widespread in the Brazilian mainland and have most likely been introduced accidentally in the archipelago.

ABSTRACT

ABSTRACT Hexapods, commonly known as insects, are a neglected taxonomic group in the Fernando de Noronha archipelago, with unanswered questions about their species richness and the ecological processes in which they are involved (e.g., colonization, introduction, establishment, and extinction). Herein, we provide an updated Hexapod checklist with current nomenclatural combinations. The entomofauna of the Fernando de Noronha archipelago is currently composed of 453 species in 21 orders. The orders, and their respective number of species, are: Blattaria (9), Coleoptera (118), Collembola (29), Dermaptera (3), Diplura (1), Diptera (134), Embioptera (1), Hemiptera (29), Hymenoptera (59), Isoptera (2), Lepidoptera (25), Mantodea (1), Neuroptera (3), Odonata (5), Orthoptera (11), Phasmatodea (1), Phthiraptera (6), Psocoptera (3), Siphonaptera (1), Thysanoptera (10), and Zygentoma (2). The archipelago has 263 new taxon records (family + genera + species). Thirty-eight species (3.39%) were described from local specimens and most of them are likely endemic species. This study more than doubles our knowledge (from the previous 190 records) of the entomofauna in this large Brazilian archipelago. This study also provides a baseline for studies on its conservation status and for implementing future environmental management programs.

ABSTRACT

Coletas recentes no estado do Maranhão indicaram que os mecópteros parecem ser abundantes neste estado. Foram estudadas 55 espécimes de quatro espécies: Bittacus diversinervis Souza Lopes & Mangabeira, 1942, B. femoralis Klug, 1836, B. latreillei (Collucci & Amorim, 2000) e Issikiella araguaiensis Penny & Arias, 1983. A maioria dos indivíduos foi coletada entre os meses de outubro e fevereiro, período chuvoso no Maranhão. Uma chave de identificação para essas espécies e a descrição da fêmea de B. latreillei são apresentadas.

ABSTRACT

In Central Amazon, Brazil, the tabanid Phorcotabanus cinereus (Wiedemann) was recorded attacking the native duck Cairina moschata (Linnaeus) (Anseriformes, Anatidae). The flight and behavior of the tabanid during the attacks and the host's defenses were videotaped and analyzed in slow motion. The tabanid was recorded flying rapidly around the heads of the ducks before landing. Landing always took place on the beak, and then the tabanid walked to the fleshy caruncle on the basal part of the beak to bite and feed. Firstly the duck defends itself through lateral harsh head movements, and then, when it is being bitten, it defends itself by rubbing its head on the body, or dipping the head into water, when swimming. If disturbed, the fly resumed the same pattern of flight as before and would generally try to land again on the same host and bite in the same place. This feeding activity was observed predominantly between 9:30 am and 4:30 pm and always in open areas, near aquatic environments, from June 1996 to January 1997, the dry season in Central Amazon. To test the attractiveness of other animals to P. cinereus, mammals, caimans and domestic and wild birds were placed in suitable habitat and the response of P. cinereus observed. P. cinereus did not attack these animals, suggesting that this species has a preference for ducks, which are plentiful in the region
