Hospedeiros e parasitóides de Anastrepha spp. (Diptera: Tephritidae) em Itaubal do Piririm, Estado do Amapá, Brasil

The occurrence of fruit flies on three host plants and their parasitoids was registered in Itaubal do Piririm, Amapa State, Brazil. Exactly 51 samples of fruits of 10 botanical species were collected and it totaled 69.5 kg. It was possible to obtain 1,169 puparia that emerged 568 Tephritidae and 105 parasitoids. Moreover, four species of Anastrepha were registered: A. antunesi Lima, A. distincta Greene, A. obliqua Macquart and A. striata Schiner. Spondias mombin, Psidium guajava and Inga edulis were the hosts of Tephritidae species, they had indexes of natural infestation of 1.3; 0.6 and 10.0 puparia/fruit and 141.1; 20.7 and 26.5 puparia kg-1 of fruit, respectively. Two species of Braconidae were obtained: Doryctobracon areolatus (Szepligeti) and Asobara anastrephae (Muesebeck).

Wild Hosts of Frugivorous Dipterans (Tephritidae and Lonchaeidae) and Associated Parasitoids in the Brazilian Amazon

We report for the first time Simaba guianensis Aubl. (Sapindales: Simaroubaceae) as a host of Tephritidae, i.e., Anastrepha fraterculus and Anastrepha parishi . Also we report new hosts for species of Neosilba . Finally we report new associations between parasitoid hymenopterans and Anastrepha species. Simaba guianensis Aubl. (Sapindales: Simaroubaceae) e registrada pela primeira vez como hospedeiro de Tephritidae, i.e., Anastrepha fraterculus e Anastrepha parishi . Foram registrados novos hospedeiros para especies de Neosilba . Adicionalmente, novas associacoes de himenopteros parasitoides e especies de Anastrepha tambem sao registradas.

New Hosts of Bactrocera carambolae (Diptera: Tephritidae) in Brazil

Summary Seven plant species are reported for the first time as hosts of Bactrocera carambolae in Brazil. Eugenia stipitata and Pouteria macrophylla, native to the Amazon region, have already been reported as hosts of the carambola fruit fly. The largest number of specimens was obtained from fruits of Averrhoa carambola and Psidium guajaua.

New Findings on Lonchaeidae (Diptera: Tephritoidea) in the Brazilian Amazon

Abstract Distribution and host data of Lonchaeidae species (Diptera: Tephritoidea) in the state of Amapá, Brazil, are presented. Adults of 10 species in the genera Neosilba, Dasiops, and Lonchaea were reared from 23 plant species in 18 families. Neosilba laura Strikis and Neosilba parapeltae Strikis are reported for the first time in the Amazon, and Dasiops inedulis Steyskal and Neosilba perezi Romero & Ruppel are reported for the first time in Amapá State. Additionally, 24 new host associations are documented.

Frugivorous Flies (Diptera: Tephritidae, Lonchaeidae), Their Host Plants, and Associated Parasitoids in the Extreme North of Amapá State, Brazil

Abstract 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.

Co-Infestation and Spatial Distribution of Bactrocera carambolae and Anastrepha spp. (Diptera: Tephritidae) in Common Guava in the Eastern Amazon

Field infestation and spatial distribution of introduced Bactrocera carambolae Drew and Hancock and native species of Anastrepha in common guavas [Psidium guajava (L.)] were investigated in the eastern Amazon. Fruit sampling was carried out in the municipalities of Calçoene and Oiapoque in the state of Amapá, Brazil. The frequency distribution of larvae in fruit was fitted to the negative binomial distribution. Anastrepha striata was more abundant in both sampled areas in comparison to Anastrepha fraterculus (Wiedemann) and B. carambolae. The frequency distribution analysis of adults revealed an aggregated pattern for B. carambolae as well as for A. fraterculus and Anastrepha striata Schiner, described by the negative binomial distribution. Although the populations of Anastrepha spp. may have suffered some impact due to the presence of B. carambolae, the results are still not robust enough to indicate effective reduction in the abundance of Anastrepha spp. caused by B. carambolae in a general sense. The high degree of aggregation observed for both species suggests interspecific co-occurrence with the simultaneous presence of both species in the analysed fruit. Moreover, a significant fraction of uninfested guavas also indicated absence of competitive displacement.

Species of Anastrepha (Diptera: Tephritidae), Their Host Plants, and Parasitoids in Small Fruit Production Areas in the State of Amapá, Brazil

Abstract Fruit flies and associated parasitoids were determined in native and introduced fruit species in the state of Amapá, Brazil. Fruits were collected every 30 d, from Jan to Dec 2012, on 3 small farms in the municipalities of Mazagão, Porto Grande, and Santana. We collected 412 samples (78 species of plants belonging to 32 families and consisting of 4,554 fruits weighing 323.4 kg) and obtained 5,252 Anastrepha (Diptera: Tephritidae) puparia from 107 infested samples (20 plant species from 13 botanical families). We report here the occurrence of 11 species of Anastrepha and 5 species of parasitoids (4 Braconidae and 1 Figitidae species; both families in the order Hymenoptera). New hosts for Anastrepha distincta Greene, Anastrepha leptozona Hendel, Anastrepha obliqua (Macquart), and Anastrepha serpentina (Wiedemann) were documented in Brazil.
