          Abstract

          As moscas-das-frutas (Diptera: Tephritoidea) são importantes pragas de frutas cítricas no Estado de São Paulo, principalmente Anastrepha fraterculus (Wied.) e Ceratitis capitata (Wied.). O objetivo deste estudo foi medir a eficiência dos atrativos alimentares para monitoramento de moscas-das-frutas, em pomar de citros. O delineamento experimental adotado foi de blocos ao acaso com cinco tratamentos e cinco repetições. O ensaio foi instalado em 30/9/2003 e desenvolvidopor nove semanas. Os atrativos testados foram: proteínas hidrolisadas comerciais Bio Anastrepha, Isca Mosca e Aumax®, todas diluídas em água a 5%; melaço a 7% isoladamente e melaço a 7% em mistura com suco de laranja a 10%. Foram utilizados semanalmente, 400mL da solução atrativa por frasco plástico McPhail instalado na copa de laranjeiras da variedade 'Pêra Rio'. As soluções eram renovadas semanalmente, ocasião em que os adultos eram coletados e çevados ao laboratório para contagem, sexagem e identificação. Foram capturados 1.821 adultos de Tephritoidea, sendo 892 de Anastrepha spp., 731 de C. capitata e 198 de Neosilba spp. Para essas espécies, as proteínas Bio Anastrepha e Isca Mosca foram altamente eficientes e semelhantes entre si, capturando 44,5% e 41,3% dos adultos de Tephritidae respectivamente. Não houve diferença entre as espécies de Tephritidae analisadas por sexo capturadas em Bio Anastrepha, Aumax® e melaço. Aumax®, melaço isoladamente e melaço + suco de laranja atraíram apenas 4,6%, 1,3% e 1,2% do total de adultos de Tephritidae, respectivamente. Melaço isoladamente e melaço com suco de laranja foram mais eficazes na atratividade de Zaprionus indianus (Gupta) (Diptera: Drosophilidae).

          Fruit flies (Diptera: Tephritoidea) are key pests in citrus production in the State of São Paulo, Brazil, mainly Anastrepha fraterculus (Wied.) and Ceratitis capitata (Wied.). The objective of this study was to evaluate food baits to monitor fruit fly population in citrus orchard. The experimental design used was randomized block, with five treatments and five replications. The experiment was set in 30 September, 2003 and evaluated for nine weeks. The attractants tested were the hydrolysate proteins Bio Anastrepha, Isca Mosca and Aumax®, all diluted in 5% water, sugar cane syrup (7%) alone and added to natural orange juice (10%). Weekly 400 mL aqueous attractants were used into plastic McPhail traps hunged within a tree of 'Pêra Rio' orange. At the time of sampling, flies were removed and conducted to the laboratory for counting, sexing and identification. It was captured 1,821 adults of Tephritoidea, from which 892 of Anastrepha spp., 731 of C. capitata and 198 of Neosilba spp. For these species, Bio Anastrepha and Isca Mosca were highly efficient and similar, corresponding to 44.5% and 41.3% of tephritid adults. No difference was detected in the attractiveness by sex of Tephritidae species provided by Bio Anastrepha, Aumax® and sugar cane syrup. Aumax®, sugar cane syrup, alone and plus orange juice, attracted only 4.6%, 1.3% and 1.2% from Tephritidae adults, respectively. Sugar cane syrup, alone and plus orange juice, was efficient to monitoring Zaprionus indianus (Gupta) (Diptera: Drosophilidae).
