Hi all,
I just read the paper about the wing spot in pest insect.
I wonder how the evolutionary of wing spot can give the advantage or contribution in the field?
Any idea?
Thank you so much!

Hi tsing_lee,

Hi tsing_lee

Wing spots have evolved in different fruitfly species as part of the courtship displays that males present to females during mating. Thus, they can be under intense evolutionary pressure to appear and be maintained, depending on whether the females find them "attractive".

Yes, I know that the wing spot is correlated with courtship behaviour. However, I wonder what the contribution of this result in actual field of study? Especially when the fly is pest

Excellent question, but access to the article is locked for me. Can you attach the full article it to your post?

Hi tsing_lee,

I'm reading through the study, and my final take is that there are transcription factors that govern several effector genes that form this morphological trait of wing spots. A certain gene, I believe dll is one such privileged gene target to modify the spatial pattern of this trait during evolution.
