Cultivation

Originally from southern Mexico, particularly Chiapas and Veracruz, Central America and northern South America, the papaya is now cultivated in most tropical countries. In cultivation, it grows rapidly, fruiting within 3 years. It is, however, highly frost sensitive.


The papaya fruit is susceptible to the fruit fly. This wasp-like fly lays its eggs in young fruit.

In the 1990s, the papaya ringspot virus threatened to wipe out Hawaii’s papaya industry completely. Two varieties of papaya, SunUp and Rainbow, that had been genetically modified to be resistant to the virus, were introduced there. By 2010, 80% of

Hawaiian papaya was genetically modified. Today, there is still no conventional or organic method of controlling the ringspot virus.In 2004 it was found that papayas throughout Hawaii had experienced hybridization with the genetically modified varieties and that seed stocks were contaminated.
