Checked my tomatos this morning and lo and behold, the damn tobacco hornworms have defoliated the top half of my entire tomato bed! I picked 16 of the bastards off my plants. Some were nearly the size of my index finger. (They obviously thrive on aquaponic tomatos!) I even found one that was eating a huge hole in a green tomato.

I didn't see any evidence of eggs from parasitic wasps on them, so I don't guess wasps have discovered the horn worms yet. Short of picking them off by hand, anybody have suggestions for horn worm control? Is there a source for parasitic wasps that I could introduce? Any other organic type treatments?

Thanks for any advice!
