Mango resistance to fruit fly: method of evaluation, resistant cultivars and resistance factors
Fruit flies are a global problem for mango production. There is a great variability in resistance to fruit fly among mango cultivars. This paper discusses and indicates the method for evaluation of cultivar resistance. Field evaluation made in Votuporanga, SP, Brazil, under heavy natural infestation, indicated that the cultivars 'Alfa', 'Ataulfo', 'Azenha', 'Espada Stahl', 'IAC 103 Espada Vermelha', 'IAC 136 Poranga', 'Roxa', 'Santo Antônio' and the selection IAC 111 are resistant. The volume of milk collected from the cut fruit petiole of six mango cultivars and three selections, ranging from highly susceptible to resistant, showed that the milk volume is related to resistance, but is not the only factor. Two cultivars with similar milk volumes were different in resistance behavior: 'Rosa' is susceptible and 'Espada Vermelha' is resistant. A brief discussion is made about the factors and the mechanisms of resistance.
