Even Bugs Die

I’m at nature a gentle sort, so much so that in the frenzy of the Vietnam-war draft, my beloved grandfather unbidden handed me a conscientious-objector reference letter. While he had sneaked away from the farm to enlist in the WWI American¬†Expeditionary¬†Forces to fight the Hun, he knew that I would never be one to kill another person.

Yet at a much lower level, he and I had teamed for years to slay insect pests. He had long farmed “patches” as he called them. These one-acre farms, one or two every summer were wide, deep expanses of vegetables and fruits, 150 running feet each. He’d plant, and from my elementary school time, I’d weed, water, train to trellis, cull, harvest, and more. Inherent in this was the elimination of bugs.

Many years later in my master-gardener course, I learned nifty terms such as integrated pest management. I already knew that part of the curriculum.

Early on, he used nasty chemicals, like DDT. He’d strap big spraying drums to his shoulder and squirt the toxins. Yet, also early on he somehow ran across the Rodale pub, Organic Gardening and quickly converted. We were out there with the pyrethrum (fundamentally a natural, harmless-to-humans insecticide made from marigolds) and with our eyes and hands. Destructive bugs did not like and died in innocuous baths of soapy water, beer, or water that had soaked the juice from a nickel cigar. I’d knock the hornworms, Japanese beetles, potato beetles and their ilk into my coffee cans of to-them toxins. While time-consuming, it killed them, did not hurt me, and did not poison the veggies and fruits.

With that background, I was a bit amused when my wife called to look at this thing on the back deck plants. Asked, she agreed it might be a bug but she was not sure.

What we had, and what had been ruining my wee, grown-from-seed tomato fruits was a tomato hornworm. What it had was parasites. The white thingummies festooned on its back were the growing offspring of a parasitic moth. It was infested and near death with wasp babies eating it from the inside.

There’s a conflict for the gentle guy.

This dreadful caterpillar has been destroying my tomatoes, fruit and plant. These wasps were gnawing at it en masse. Shortly the hornworm will die, the wasps will grow and fly off to create more parasites.

Who should feel sorry for whom?

Truth be told, as a gardener from childhood and by avocation and certification, I have little use for insects that live to eat my crops. Yet a small part of me empathizes with the reality of being eaten alive from the inside by nasties.

I think we could well do without the hornworm. Some versions of it munch on tobacco, which distresses me far less. I don’t have tobacco salads and sandwiches. I also think we could do well without mosquitoes, even though many bats and birds consume them as main parts of their diets.

My wife is very unhappy at the sight and thought of of the besieged caterpillar. I had no problem clipping the leaf and tossing the mess aside. I know that the wasps will finish their business and thrive. I might even hum The Circle of Life.
