Most people put brown paper bags around the fruit when it is small to keep the worms out. Here's an old thread about it.

This page from UF tells you when to start bagging and other control methods

Maybe papaya fruit fly? I have had probs w/them as well & IME, they seem to prefer some varieties over others.

That's the wasp! I see them on the fruit. Dam, I guess they are all lost. Thank you Dirty. I'll read the link when I get home.

For me some varieties seem to attract more flies. If you hose off the outside bits on less attacked plants, the fly sometimes seems to forget where the plant was hiding. I think that the covering idea is probably more effective. Red Lady, Taining, and Waimanula seem to be chosen less than TR Hovey in my garden.

Are those white bubbles signs they have injected their eggs? Did a bit of research but my fruit is full of those white things. I even see it on the new little fruit.

The 'bubbles' are sap leaking out from the pierced skin of the fruit after the fly deposits its eggs into the fruit cavity.
