If there was only one kind of creature in the world that had to go extinct, what would it be?

I don't want any creature to go extinct nyang~ Each creature plays an important role in this ecosystem ㅠ_ㅠ We have to respect biodiversity nyang~ But if I had to choose one, it would be one of the harmful pests nyang~ However, this should only be considered as a necessary measure Nyan~ Anyway, absolute extinction is a sad story Nyan

This is a mosquito ㅇㅇ;;
