Or try row covers.

starwoodfarm, I googled Silver Plastic Mulch (SPM) and found the results of an experiment conducted at Knoxville Plant Science Farm by the University of Tennessee.
It is a single trial done on tomatoes.
The results suggest that Coleoptera, to which belong the flea beetles, were trapped in significantly less numbers on SPM than on regular black plastic. This evidence suggests that SPM reduces the number of flea beetles.
There is no information on the site to indicate the cost effectiveness of SPM over the regular black plastic.
I would consider it another potential item in the toolbox of IPM.

Floating row covers, and getting your soil into a good, healthy state are better ways to control insect pests.

I've learned a lot here from you, kimmsr, and others about conditioning soil, and that is my preferred anti-bug war strategy. I have 12 very large compost piles going under the snow, and spread shredded leaves, horse and llama manure and spoiled hay on my entire two acres last fall. I know this will help with pests. I was just curious about the possibility of the silver mulch as extra insurance.

I don't like using row covers due to the looks. I have to use them for frost protection, so am hoping to not use it for the bugs.

I am interested in any personal evidence on the silver. It's surprising how much data is NOT out there considering that many of the seed catelogues are selling the stuff.

Thank you Ronalawn for the university study information. I think I will get some and try my own tests this year.

Thank you all
Laura
