However, some diseases, such as sticky disease of papaya plants, caused by the Papaya meleira virus (PMeV), break the natural resistance of fruits to fruit flies, enabling them to be infested while still unripe. Therefore, this study of the relationship of papaya sticky disease with C. capitata under field conditions was conducted to determine the period of security to guarantee the harvest of papaya fruits free of fruit flies in areas where sticky disease is endemic. Infestation of papaya fruits by C. capitata was evaluated from uninfected plants and from sticky disease infected plants, in seven stages of the disease and three stages of ripening of fruits. A direct relationship was observed between time of sticky disease symptoms and infestation of fruits by the Medfly, and it was determined that a period of four weeks after the first appearance of the symptoms of sticky disease in papaya plants was the period of security in which infestation of fruits by fruit flies did not occur. Infection of papaya plants with sticky disease was associated with a reduced level of benzyl-isothiocyanate (BITC), from 43.1 ?g ml?1 to 1.7 ?g ml?1, a natural chemical compound in the latex of papaya fruit, and considered to be associated with resistance to fruit flies.  aBenzyl-isothiocyanate (BITC)  aCarica papaya  aCeratitis capitata  aMedfly  aVirus1 aVENTURA, J.
