Abstract
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.
Highlights
The guava Psidium guajava L. (Myrtaceae) is a native species of tropical America, possibly ranging from Mexico to Peru, where it still occurs in a naturally occurring state (Menzel, 1985)
The objectives of this work were: to perform a faunistic analysis based on the Anastrepha species captured in McPhail traps in a guava orchard in Boa Vista, Roraima; identify the species infesting the collected guava fruits; and identify their associated parasitoids
In the Northeast, CenterWest, Southeast, and South regions of Brazil, A. fraterculus, A. obliqua, A. sororcula, A. zenildae, and the exotic species Ceratitis capitata are the most relevant species, alternating in dominance according to location (Uchôa et al, 2002; Raga et al, 2005; Moura and Moura, 2006; Dutra et al, 2009; Azevedo et al, 2010)
Summary
The guava Psidium guajava L. (Myrtaceae) is a native species of tropical America, possibly ranging from Mexico to Peru, where it still occurs in a naturally occurring state (Menzel, 1985). The state of São Paulo is the largest producer, with 5,076 hectares planted, followed by the state of Pernambuco, with 4,512 hectares (Agrianual, 2009) Despite these expressive production levels, the presence of pest insects compromises the health of Brazilian guava crops and is a major obstruction to guava commercialisation, both in the domestic and international markets. In this context, fruit flies (Diptera: Tephritidae) are considered extremely important because they are the most common fruit pests, causing direct damage to the product, and commercial limitations (Malavasi, 2000)
