Maintaining the human population below 500 Million should be easy.
First, eliminate everyone in China, India, Japan, Korea and Southeast Asia. Then, eliminate everyone in the rest of Asia. Get rid of everyone in Africa and Europe too.
Eliminate everyone in South and Central America and Canada.
Then, we pretty much have 330 Million Americans + Australia and all of the islands remaining, which should total to about 500,000,000.
Then, we have to implement birth control to keep it there. No problem.
