The guava fruit (Psidium guajava) is among the most strongly affected by fruit flies in Brazil. In the Brazilian Amazon, 11 species of Anastrepha have been reported in guava orchards to date. This work aimed to identify the species of Anastrepha present in a guava orchard in the municipality of Boa Vista, determine the species infesting the fruits, and identify any parasitoids present. Two McPhail traps with food bait were installed and weekly collections were made between January and December 2008. Fruits were also collected systematically during this period, with a view to determining the association between host plant and tephritid species. Nine species of Anastrepha were identified, in addition to one specimen belonging to a probable new species. Anastrepha striata Schiner, Anastrepha sororcula Zucchi, Anastrepha obliqua (Macquart), and Anastrepha fraterculus (Wiedemann) were the dominant species in the orchard, accounting for 84.8% of all captured individuals. All females collected directly from fruits were A. striata. Doryctobracon areolatus (Szépligeti) was the only parasitoid species obtained. In this work, Anastrepha ethalea (Walker) is reported for the first time in the state of Roraima.
The purpose of this study was to elaborate a preliminary list of the mite species associated with rubber trees in the municipality of Santana, in the state of Amapá, Brazil. Two collections of rubber tree leaves were conducted on May 2 nd and June 5 th , 2010. Twenty-five plants were sampled at random. Three leaves were collected per plant, from the lower third of the crown. The samples were placed in paper bags, packed in an isothermal box chilled gel-based pulp plant (Gelo-X ® ), and transported to the Entomology Laboratory at Embrapa Amapá, in Macapá. The leaflets were examined under a stereomicroscope, and the mites found on the adaxial and abaxial surfaces of the leaves were collected with a stilet, mounted on microscope slides in Hoyer's medium, and later identified. We collected a total of 1,722 mites of 10 families: Acaridae, Cunaxidae, Eriophyidae, Iolinidae, Phytoseiidae, Stigmaeidae, Tarsonemidae, Tenuipalpidae, Tydeidae, and Winterschmidtiidae, in addition to unidentified species of the suborders Oribatida and Astigmatina. The family Phytoseiidae represented only 2.90% of specimens collected, but showed the highest species richness (5 species
RESUMO Este trabalho foi realizado no Distrito de Fazendinha, Macapá, Estado do Amapá, com o objetivo de identificar as espécies de moscas-das-frutas ocorrentes em um pomar de goiabeira. Foram instaladas 4 armadilhas tipo McPhail contendo como isca proteína hidrolisada de milho a 5%, em um pomar com aproximadamente 100 plantas, com cerca de três anos de idade. De outubro de 2006 a janeiro de 2007 foram capturados 115 exemplares de Tephritidae (44 machos e 71 fêmeas), todos pertencentes ao gênero Anastrepha: A. antunesi Lima, A. distincta Greene, A. fraterculus (Wiedemann), A. striata Schiner, A. obliqua (Macquart) e A. shannoni Stone. O período de maior ocorrência foi o mês de janeiro, com predominância de A. striata. Este constitui o primeiro registro de A. shannoni para o Estado do Amapá.
