Thank you for your question. Although I can't see the spots clearly enough to provide a reliable diagnosis, this appears to be a fungus known as Pacific Coast Pear rust, rather than an insect. https://ucanr.edu/datastoreFiles/268-561.pdf
I suggest that you submit leaf samples to the OSU Plant Clinic, where they can be examined: https://bpp.oregonstate.edu/how-submit-plant-materials
Good luck!

Hi, the link you sent is to a story about Japanese maples. Not pears. Please advise.
