Abstract. We report for the first time the presence of Ceratitis capitata (Wiedemann) (Diptera: Tephritidae) in the state of Acre, Brazil, reared from guava fruit (Psidium guajava L.) and star fruit (Averrhoa carambola L.). This finding increases our knowledge about the geographical records of this fruit fly in the Brazilian Amazon.
The objective of this study was to evaluate the potential of the pioneer plant species Bellucia grossularioides (L.) Triana (Melastomataceae) to act as a reservoir for parasitoids of fruit flies in the Brazilian Amazon. We collected 48 samples of fruits (total of 4,012 fruits, 43.98 kg) during the months of July, August and September of 2013, in 15 of the 16 municipalities of Amapá State, Brazil. All samples showed infestation by fruit flies, with rates varying from 60.6 to 239.1 puparia/kg of fruit (mean of 106.8 puparia/kg of fruit). The percentage of emergence varied 18.6 to 64.3% (mean of 39.9%). Specimens of Anastrepha coronilli Carrejo & González (Diptera: Tephritidae) were obtained from all samples collected. Specimens of Neosilba (Diptera: Lonchaeidae) were obtained from five samples, where they were represented by Neosilba bella Strikis & Prado and Neosilba glaberrima (Wiedemann). The mean percentage of parasitism was 12.8%, varying 4.7 to 26.7%. Four species of parasitoids were obtained: Doryctobracon areolatus (Szépligeti), Doryctobracon sp.2, Opius bellus Gahan (Braconidae) and Aganaspis pelleranoi (Brèthes) (Figitidae). Doryctobracon areolatus, present in all municipalities sampled, was the most abundant species. Considering that B. grossularioides is a plant species that is abundant in the area sampled, its relevance with respect to the maintenance of the population of parasitoids is discussed in the context of the integrated management of fruit flies in the Amazon.
RESUMO. Este trabalho teve o objetivo de registrar a ocorrência de espécies de Anastrepha e parasitoides associados a frutos de Spondias mombin em três municípios do estado do Amapá, Brasil. Foram realizadas coletas de frutos de S. mombin nos municípios de Oiapoque, Porto Grande e Mazagão (10 amostras por município, cada uma composta por aproximadamente 1 kg de frutos), em fevereiro e março de 2014. Foram obtidos 2.715 pupários, dos quais emergiram 891 espécimes de Anastrepha e 261 de himenópteros. Os índices de infestação foram variáveis, sendo o maior valor médio registrado em Porto Grande (99,8 pupários/kg de fruto). Quatro espécies do gênero Anastrepha foram obtidas: Anastrepha obliqua (Macquart), Anastrepha antunesi Lima, Anastrepha fraterculus (Wiedemann) e Anastrepha striata Schiner. A espécie mais abundante nos três municípios foi A. obliqua. Das 29 amostras infestadas por moscas-das-frutas, apenas sete (24,1%) não apresentaram parasitismo. O maior percentual médio de parasitismo foi registrado em Mazagão (18,9%). Foram obtidos exemplares de cinco espécies de parasitoides: Opius bellus Gahan (50,6% do total), Doryctobracon areolatus (Szépligeti) (26,8%), Asobara anastrephae (Muesebeck) (16,5%), Utetes anastrephae (Viereck) (5,7%) e Aganaspis pelleranoi (Brèthes) (0,4%).
We conducted a survey of frugivorous flies (Diptera: Tephritidae and Lonchaeidae), their host plants, and associated parasitoids in the extreme north of Amapá State, Brazil. Fruit were collected from various plant species between May 2011 and Jul 2013. In total, 218 fruit samples were collected (3,915 fruits, 115.6 kg), from 33 plant species (12 native and 21 introduced) in 22 families. Infestation by fruit flies was observed in 69 samples, representing 17 plant species in 13 families. In total, 3,480 puparia were obtained, from which emerged specimens of Anastrepha Schiner (6 species; Tephritidae), Neosilba McAlpine (4 species; Lonchaeidae), and Bactrocera carambolae Drew & Hancock (Tephritidae), as well as wasp parasitoids in the family Braconidae (3 species). This work adds new records of frugivorous flies in the studied area and establishes new relationships between species of frugivorous flies and host plants in the Brazilian Amazon.
