Question
Asked 16 January 2025

Can anyone help me identify this pest?

Hi! My name is Gabrielle, and I'm a biology student.
In my internship, I need to identify the pest on these leaves.
I know the tree species is Annona coriacea Mart.
My professor and I believe it might be a type of cochineal/mealybug. If anyone can assist with the identification, it would be greatly appreciated!
Thank you in advance!

It seems to be an aleurode species, you can keep some of those larva/pupa and wait until the emergence of adultes it'll help to get what species is exactly.

I think it's the orange spiny whitefly, Aleurocanthus spiniferus (Quaintance) (Hemiptera: Aleyrodidae). Anyway, more information can be found here: https://onlinelibrary.wiley.com/doi/full/10.1111/epp.12759.

Now I'm going to collect more material and wait for the adults to emerge in the lab. When I finally get images of the adults, I will share them again for final confirmation.
