We continue to try to find the best ways to organically deal with bug pressure. Since we have lifted the row covers, the cucumber beetles and squash beetles have been ever present. I guess it is to be expected because we have 15 rows of cucurbit plants (cucumbers, melons, and pumpkins) they LOVE.
At first, the little cucumber beetles were easy to catch and squish; however, they must have gotten a prescription for steroids, because they are now HUGE! Huge bugs have huge appetites and also cause more damage. The most damaging part of an infestation of cucumber beetles is that they transmit bacterial mosaic and wilts with their mouths. When they are actively feeding again they transmit the diseases from plant to plant. Symptoms of these diseases are wilting and death of plants.

We have noticed some wilt and damage to our pumpkin plants as well as some of the cucumbers. We are also noticing fungus like spores on some of our pumpkin plants which are rotting a few of the baby pumpkins.

I have caught and squished more beetles than I can count. Today, I tried using my battery operated vacuum, but it ran out of power after one row, so it wasn't that helpful. I have also sprayed two organic products - neem oil and diatomaceous earth to try and cut down on the number of huge, hungry beetles. Unfortunately, the infestation doesn't seem to be gone yet and I am worried the cucumber beetles are going to start eating my watermelons and cantaloupes.
When farming, I am struggling with wanting to protect every single plant because of the time I spent growing them from a seed and the emotional attachment I have gained along the way. Yes, they are plants and I may be too sentimental. I also realize that I am getting a little too angered at bugs that are doing what comes natural to them because will affect MY harvest. I am tempted to go buy insecticide that will just kill the cucumber beetles - the quick fix. However, those insecticides don't just damage the bugs. They could also damage the soil, my lungs, and whoever eats the produce we are growing. The organic philosophy is to treat the earth well and feed the soil with nutrients not toxins and in turn it will be able to grow healthier produce. We are still building up the soil and learning about what to do to help and not hurt the earth.
I recognize the importance of companion planting to bring in beneficial insects that eat the pest bugs. I would love it if beneficial bugs could eat all of our cucumber beetles. We have noticed small pockets of tachnid flies, assassin bugs, and other beneficial insects that eat cucumber beetles; however, the infestation is too much for them to cure. Since, it is too late to plant the beneficial plants this season, Damian and I have one more organically approved product - pyrethrum (derived from chrysanthemums) - we are going to try before we learn a hard lesson and harvest what the cucumber beetles don't eat.
