GATTELLI, Tacimara et al. Frugivorous flies in myrtaceans and orange trees 'Céu' in the region of Vale do Rio Caí, Rio Grande do Sul State, Brazil. Cienc. Rural [online]. 2008, vol.38, n.1, pp. 236-239. ISSN 0103-8478. http://dx.doi.org/10.1590/S0103-84782008000100038.
This study aimed at recognizing frugivorous flies species in Myrtaceae: Eugenia uniflora L., Campomanesia xanthocarpa Berg. Psidium cattleianum Sabine, Psidium guajava L. and Acca sellowiana (Berg.) Burret., as well as in Citrus sinensis (L.) Osbeck (Rutaceae), at Vale do Cai region, Rio Grande do Sul. Fruits were collected at the maturation stage of each fruit species between October 2004 and July 2005, and at the laboratory they were placed in pots with sand and were kept at 12h photoperiod, 80 ± 10% RH and 25 ± 1°C. Pupae were individualized and their characteristics were recorded. In Tephritidae only Anastrepha fraterculus (Wied.) was recorded and in Lonchaeidae, Neosilba n. sp. 3, Neosilba zadolicha McAlpine & Steyskal and Neosilba certa (Walker). These last two species were recorded for the first time in Rio Grande do Sul. Only on P. cattleianum all species were recorded. Results show that A. fraterculus is the most frequent fruit-fly species found attacking the studied fruit plants in Vale do Caí region.
