Why do all the bitter oranges I get from about 10 trees, about 95% have warms inside. I use the bitter oranges to make marmelade. What can use to prevent the fruits from having warms? There are no holes in the outside of the fruits, so I think the warms develop inside. Thank you
I'm not familiar with this problem but I'm guessing the worms are actually larvae, possibly from citrus fruit borer. A search on the common name turns up Ecdytolopha aurantiana and Citripestis sagittiferella. Any resemblance of these larvae to yours?
I don´t have an orange right now, I will check tomorrow morning to see if there are any of the trees have fruit, and I will post back Thank you!
