Biodiversidade de moscas frugívoras (Diptera: Tephritidae e Lonchaeidae) em diferentes regiões do estado de Alagoas

Abstract

This study aimed to know the diversity of the fruit flies, their hosts in six counties in two regions (south coast and valley Mundaú) of the State of Alagoas. Fortnightly, fruits were collected from : carambola, mango, rose apple, cherry, cherry, guava, orange, ingá, hog plum, guava, Massaranduba, tangerine clove, hog plum, orange and lime juá so randomly at different times of the crown of fruit and freshly fallen fruit on the ground, which were in good condition of conservation and without exit holes of the larvae. The fruits were placed in plastic trays (54cm x 32cm) labeled with field data having a layer of a cm sieved sand and sterilized in an oven with air circulation for 48 hours at 80 °C to serve as a substrate for pupation . The identification of the Anastrepha species was based on females mainly by observing aculeus the apex, following the identification keys. C. capitata was the species that has infested the highest number of fruit (seven) (guava, cherry, rose apple, carambola, mango, hog plum and acerola) from four different families (Myrtaceae, Oxalidaceae, Anacardiaceae and Mapighiaceae). Identificadied were six species of flies of the fruit in regions 1 and 2, Anastrepha serpentina (Wiedemann, 1830), Anastrepha zenildae Zucchi, 1979 (Diptera: Tephritidae), Anastrephasororcula Zucchi, 1979(Diptera: Tephritidae), Anastrepha obliqua (Macquart, 1835) (Diptera: Tephritidae), Anastrepha fraterculus (Wiedemann, 1830) (Diptera: Tephritidae) and Ceratitis capitata (Wiedemann, 1824) (Diptera: Tephritidae).Os weather temperature data and precipitation influence the development flies to the fruit in all estudied.Guava, carambola and hog plum are the fruits that suffer the greatest infestations of flies of the fruit . Neosilba was plagued many fruit in the municipality of Coruripe , but with greater predominance in acerola in other municipalities . C. capita is the species associated with the largest number of hosts in Region 1 ( the municipalities of Coruripe , Penedo and Junqueiro ) . A. fraterculus was the species associated with the largest number of hosts in region 2 (counties of Branquinha , União dos Palmares and Santana do Mundaú ) . A. fraterculus was the dominant and most common species. C. capita and A. fraterculus were considered theconstant species.
