First record of the association of banana (Musa sp.) and Ceratitis capitata (Widemann, 1824) in Brazil

Abstract Brazil is the fourth world’s largest banana (Musa spp.) producer and largest consumer. Mediterranean fruit fly Ceratitis capitata (Wiedemann, 1824) (Diptera: Tephritidae) is the main pest of quarantine importance in the exploration of fresh fruits. This species has shown wide ecological plasticity, with adaptation in several native and exotic hosts and different edaphoclimatic conditions. In November 2017 and March 2018, banana samples of AAB subgroup, Prata Anã, Prata Pacovan and Prata BRS Princesa, were collected from orchards located in the fruit producing region of São Francisco, Juazeiro, Bahia, Brazil. Fruits were sent to the laboratory for processing aimed at obtaining adults. A total of 177 tephritid pupae were obtained in Prata Anã variety, emerging 106 C. capitata adults. The total infestation rates in puparia kg fruit-1 and puparia fruit-1 were 7.45 and 0.70, respectively. Thus, the association between banana and C. capitata was recorded for the first time in Brazil and the probable implications related to this bitrophic association will be discussed.

摘要：巴西是全球第四大香蕉（芭蕉属（Musa spp.））生产国与最大消费国。地中海实蝇（Ceratitis capitata (Wiedemann, 1824)，双翅目实蝇科）是鲜水果检疫防控领域的主要检疫性害虫。该物种生态可塑性极强，可适应多种本土与外来寄主植物，以及不同的土境气候条件。2017年11月与2018年3月，研究团队于巴西巴伊亚州茹阿泽鲁市圣弗朗西斯科果品产区的果园中，采集了AAB基因组群香蕉品种Prata Anã、Prata Pacovan与Prata BRS Princesa的果实样本。将采集的果实送至实验室开展处理，旨在获取实蝇成虫。其中，在Prata Anã品种中共计获得177头实蝇蛹，羽化后得到106头地中海实蝇成虫。每公斤果实的蛹壳数、单果蛹壳数分别为7.45与0.70。本研究首次在巴西记录到香蕉与地中海实蝇的双营养级关联，并将探讨该双营养级关联可能带来的相关影响。
