Certified ExpertA.If by the bottom leaves, you mean the cotyledon leaves - which are the first leaves the plant gets after sprouting, this is normal. Plants drop their cotyledon leaves after they have a few true leaves.
If the plant is dropping/yellowing its bottom true leaves (also referred to as their second leaves), then this indicates either a lack of water or a lack of nutrients. It will correct itself with some additional water or with some diluted fertilizer.

Certified ExpertA.You may have a slime mold or sooty mold, which is feeding off the honeydew produced by the bugs. The bugs are likely aphids. This article will help with them:

June 25, 2012Q.zucchini leaves that are fully spotted in brown
Zucchini leaves are fully spotted in brown and are covered with small holes. Leaves seem to be eaten away. Never saw this before and have been growing them for years. I used my own seeds this year. . . have they been contaminated?

June 26, 2012Q.What would cause little holes in the leaves of my zucchini plant leaves
The plants were grown from seed, and have looked really healthy until this weekend. Now the most mature leaves have a lacy look, with lots of holes. I do not see any little insects. There is a bit of white or brown around the holes both on the upper and undersides of the leaves -- I am actually Zone 2, not Zone 5.
