Flea Beetle Circus
Step right up, folks. For one thin dime--one tenth of a dollar--you too can witness the amazing...
The leaf damage shown below is from a Ping Tung Chinese eggplant. I know it's flea beetle damage, because there are flea beetles partying on the leaf. They are not shy. They hardly moved when I place the dime on the leaf, and then moved only to climb onto it, and check out FDR's likeness. As you can see, one of these flea beetles is just a bit larger than Franklin Roosevelt's nose.
Flea beetles on eggplant.
Flea beetles visibly resemble fleas, because they have rear jumping legs.
Without some poison, they will completely devour an entire eggplant, no matter how large. So I apply permethrin powder to the leaves, remove any open blossoms (to protect pollinators), and I do this only with eggplant. I don't think I would want to smoke tobacco leaf that has had permethrin applied, even though I can't point to any specific toxicology study. [I can imagine the facial expressions on NIH functionaries as they review the grant proposal for studying the wellbeing of smokers who apply permethrin to their tobacco.]
Flea beetles have a thing for eggplant. Adjacent peppers (also in tobacco's
solanaceae family) are left untouched. In the past, I've observed that flea beetles--like each of us--are partial to specific varieties of tobacco.
