Here's a pictu

Yellowy spots all over, the tomato feels slightly sticky. THere are
little (1/4 inch) amber colored insects on the plants with two small
black dots that run on thier backs near the tail.

What are they, what do I use to kill them, and how do I keep them away?

I'm not averse to chemicals.

Thanks in advance,

Jay
