Hi Mary, thanks for the question.
Zucchini is pollinated by bees. Squash bees are best, but honeybees will also help pollinate the plants. As long as you have both male and female flowers and are not getting zucchini you may have to hand pollinate. Parthenocarpic varieties can produce fruit without pollination. Check out the following links:

I hope this is helpful.
