Will my garden attract a lot of insects?

I have a large vegetable garden (can't say exactly how big, too lazy to measure.) Where right now I have planted some broccoli, spinach (which Im probably going to get rid of soon and replace with something else-- it's not standing up to the heat which I expected, but I didn't expect it to get so hot so early this year), carrots, lettuce, and eventually once I can pick up more manure some cayenne peppers, tomatoes, and collards-- I may then plant a few other things if I have space. I then have a small flower garden/herb garden on the side which is about 10-15 square feet and I'm going to interplant some echinacea, cilantro, chamoile, sweet basil, parsley, dill, catnip, and maybe foxglove. I may also plant some sage/rosemary. I'm also putting cilantro, basil, parsley, chamomile, and catnip in pots to move around the vegetable garden. Then I have a small rose of sharon tree and a small persimmon tree, and some baby blackberry bushes that probably won't fruit this year... I also have a few plants around the house like irises, roses, cannas, and torch lilies. Thanks! What I want to do is create a balanced ecosystem so that pests can be kept down while still providing enough food for predatory insects and birds. Last year I would have 20+ dragonflies in my backyard due to a pond about half a mile away. I guess they liked it there. :P
