cucumber zucchini

My cucumber and zucchini plants did not do well last season. Are there varieties that are self pollinating?
These plants have separate male and female flowers on the same plant and depend on bees or people to carry pollen from the male to the female flowers. In a small garden bees may not notice the flowers or weather may be cool. Bees are scarcer now and they also are less active when it is cool and wet.
