Tiny whitish bugs
I noticed leaf-curl on some low leaves of my Early Girls. Within a day or so I had many tiny holes in some leaves. With a magnifying glass I could find tiny bugs on the bottoms of the leaves. Under 20x magnification I could see they are wingless, with bulbous bodies, black dots that appear as eyes, almost translucent, and either whitish or perhaps slightly greenish. They don't hop. Last night I sprayed with pestacide, Sevin. Today there are still bugs on some leaves. They are not bigger than the dot at the end of this sentence.
What are they? What should I do about them?
