FTA:  In some cases, plant distress signals can even summon help from other species. That's what happens with the tomato. When caterpillars nibble on the plant's leaves, the leaf pores release volatile chemicals that are detected by a type of parasite: a wasp that lays eggs inside caterpillars. (Not to overwork the horror-movie analogy, but as with the hapless astronauts in the "Aliens" franchise, it doesn't end well for the caterpillar.)

That is so frickin' cool.  Thanks, Subby!

Tomato fruitworm is also called cotton bollworm and corn earworm.

Sounds versatile, in a bad way.  Haven't seen any in Oregon and would like it to stay that way.

AAAAGGGGHHHH: Show this article to the first jerk vegan you see and tell them salads are murder.


Never met a jerk vegan over 21 or one who had practiced the diet seriously over a couple of years or more no matter their age. I've met some who push back after several minutes of "bacon, what about bacon? If you only had my steak..." shiat like that. Like a dummy talking to his first gay acquaintance, kinda dumb.

That being said, this is kinda cool and creepy.

Had one porch tomato plant in Vegas that got eaten by one of these. I was not happy. Desert, lone plant, one in a million moth egg drop.

So if the plant gives off something, it should be detectable and they are receptive to similar. Give me the right smells and we can talk to plants.. What does hello smell like?

I've seen those little buggers, mostly on cannabis plants.  They ruin the buds.  Never had them on my tomatoes, but thanks to subby, I will now be on the lookout since I just planted some tomato seedlings.  Thanks, subby.

I used to hate hornworms on the tomato plants growing up. So creepy so big, and so juicy when they got squashed. Clicking away freaking me out as I was trying to pick tomatoes.

Moved to a different part of the province and I haven't seen one in two decades.

Potato beetles either.

Makes gardening a little nicer.

As a child my Dad had a few tomato plants and gave me 25 cents per worm , he had a small can of motor oil we put them in. A friend asked him why he doesn't just spray to get rid of them and he said "they won't get immune to getting drowned in oil."

Caterpillars eat the tomato plants, wasps eat the caterpillars. I swear once the wasps figured out that I was watering the tomato plants, they were cool with me.
