Cucumber beetle mass trap development and field evaluation
On most farms, Diabrotica beetles are only severe in certain years, a pattern for which there is yet no analysis. Therefore, for most organic farms these beetles are tolerable in most years. However, in certain seasons some help in reducing numbers may mean the survival of many crops, particularly where beetle damage to seedlings essentially destroys the crop. Example crops are beans and early season cucumbers. Sweet corn is also such a crop, although the damage only interferes with the proportion of kernels which are fertilized.
