As I understand it, tomatoes can be pollinated by the wind, so in that
respect you would probably be ok.

But I wonder what you would be trying to accomplish with the "insect proof
cage"? In my experience, tomatoes are not particularly prone to insect
damage. The exception might be tomato hornworms, but they are large and
relatively easy to spot and remove. And it seems to me that it would be
very difficult to exclude all insects, given that you need access to the
plants to prune and pick. There's bound to be a spot where something as
small as an insect could gain access, and you might end up trapping more
insects than you exclude. It doesn't seem like a very practical or
necessary idea.

Are insects necessary to pollinate tomatoes. Was thinking about
making insect proof cage of plastic window screening to keep them away
but was wondering if the bigs are essential for pollination.
