Squash leaves turning yellow

Question from Angela

I am having trouble with my squash plants. The leaves are turning yellow and the squash are going bad before they get more than 3-4 inches long. Someone mentioned it might be a vine bore. How can I get rid of it and is there any chance of saving my plant?
Thanks
