Here is the link to the Cornell organic insect and disease control website for anyone who is interested.  Everything can be downloaded as a pdf file.  (This site is as good as ATTRA)

I am interested in the high tunnel rowcover with trellis idea also but as the varmint overwinters in the soil, I wonder about the economics of the set-up with crop rotation (that might be balanced by the ease of harvest though).  I once observed the beetles actually marching along the drip tape from plant to plant.  The driptape highway under the canopy protected them from predation above and below. Hard not to get anthropormorphic about that.

I'm going to try the yellow cup traps next season.  (I had no beetle damage on the white flowered gourds growing nearby the cucumbers; unfortunately we can't eat the gourds)

  Currently I am managing a historic garden and must use historically accurate methods which precludes nematodes, I suppose.  I did check with Coleman's book expecting his lecture on tending to soil balance; that's frustrating given the number of seasons required to restore the balance in a disturbed area.  I also have tried vacuuming up the bugs...sort of fun in a macabre way, but slow and high labor too.

I would like to think that the beetle population is temporarily very high, but this fellow has been my worst pest for thirty years in many locations.  Often, it's the wilt that's spread by them that's most damaging.  I lost all melon vines this past season before the fruit could ripen for the beetle to eat.   Shawnee, zone 5

Cucumber beetles are a royal pain.  One thing I have tried with partial success is to fill yellow plastic bowls or cups with a soap solution.  I place these every few plants down the row.  The beetles are attracted to yellow and assume the bowls/cups are flowers.  This catches some but they proliferate so rapidly that it is not a complete solution.  Row cover and successive plantings seems to me to be the best organic solution.  Eliot Coleman's books claim that a well balanced soil will help fend off cucumber beetles.  He advises using sheep manure and dried seaweed.

Has anyone on this list ever tried to create a temporary hoophouse (field tunnel) using row cover instead of plastic?  I am envisioning a structure just tall enough to walk through and trellising the cucumbers.

I would like to hear of any organic cucumber beetle control that other growers have tried.  (I  think that bats wouldn't help since they are nocturnal when the beetles aren't active)  I know of people using the kaolin clay sprays-but those get expensive too.
