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.

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.

Frugivorous Flies (Diptera: Tephritidae, Lonchaeidae) Associated with Fruit Production on Ilha de Santana, Brazilian Amazon

Abstract We conducted a survey of the species of frugivorous flies (Tephritidae and Lonchaeidae), their hosts, and their parasitoids found on Ilha de Santana, Amapá State, Brazilian Amazon. We also assessed host plant use by Bactrocera carambolae Drew & Hancock. Fruits were collected from various plant species, at 30 d intervals, from Jan to Jul 2015. In total, 149 fruit samples were collected (3,142 fruits, 76.3 kg), belonging to 20 plant species (9 native and 11 introduced) in 13 botanical families. Infestation by fruit flies was observed in 86 samples (11 species in 8 botanical families). Specimens of 5 species of Tephritidae and 4 species of Lonchaeidae fruit flies were obtained, as well as 3 species of braconid parasitoids. The most important fruit fly species on Ilha de Santana are: B. carambolae, for being a species of quarantine importance; and Anastrepha obliqua (Macquart) and Anastrepha striata Schiner, for infesting plant species of local socioeconomic importance. Averrhoa carambola (Oxalidaceae), Eugenia uniflora (Myrtaceae), Malpighia emarginata (Moc. & Sesse) ex DC. (Malpighiaceae), and Psidium guajava (Myrtaceae) are the host plants responsible for sustaining the population of B. carambolae.

Potential of Amazonian isolates of Metarhizium to control immatures of Bactrocera carambolae (Diptera: Tephritidae)

Summary This study shows the potential of Amazonian isolates of Metarhizium Sorokin to control immatures of Bactrocera carambolae Drew & Hancock (Diptera: Tephritidae), a quarantine pest present in Brazil. Our results reveal the effectiveness of an isolate of Metarhizium anisopliae (Metsch.) Sorokin to control immatures of B. carambolae, suggesting the potential for direct application of this isolate onto the soil to reduce populations of the pest.

First record of Tenuipalpus uvae De Leon, 1962 (Acari: Tenuipalpidae) in Brazil

This is the first record of Tenuipalpus uvae De Leon (Tenuipalpidae) in Brazil. Specimens were collected from Spondias mombin L. (Anacardiaceae) in the states of Amapa (northern Brazil) and Pernambuco (northeast).
