GardenWeb Florida Forum, we identified the little worm that's been damaging my tomatoes and eggplants: the Tomato Fruitworm Moth larva (Heliothis zea). The damage isn't severe, particularly this time of year, when the rains and humidity are low. But that damage would be a more serious issue in July. Organic control is good old reliable BT or Spinosad ( Monterey Garden Insect Spray). The Gardener's Guide to Common-Sense Pest Control indicates that Neem should work, too, presumably as an antifeedant.
The damage on my 'Little Fingers' eggplants seems less severe, presumably due to its thicker skin. The damage seems to have been inflicted over a fairly short duration, since new fruits are unaffected.
