The borers wiped out all my zucchini plants two years ago, so I
planted none last year and I'm giving it another try this year. There
are "good" years and "bad" years.


Very true. The vine borers winter in the ground, so many times the population
can be diminished by turning under all plant debris in the fall and planting a
cover crop. For those of you in northern climes a hard winter will also reduce
the overwinetring adults.
