Aphids? Leaf curl up, tomato rot before turing red
Hi This is my first year of tomato growing. I have four tomato plants, three of them have tomatoes on them, havn't turn red/orange yet. I started noticing some curl leaves since last week, and one tomato found half rot still on the branch. I looked into every leaf carefully, there're some very tiny aphid look insect, black, some have white stripes. They jump and disappear when you try to touch them. Some eggs on the leaves too. Can the "aphids" cause rot fruit? I sprayed some dawn liquid with water, doesn't do much help since these "aphids" quickly disappear. Noticed some "aphids" on my bell pepper plant too.
Here are some images, overall:
"aphid" and the eggs on leaf:
some brownish marks on stem and fruit
Thanks a lot!
