To me it looks like scale, not 100% on it though. Not too experienced with pesticides at the moment but if it is scale, you gotta hit them twice. First time kills the adults and then you have to wait for the eggs to hatch to get them the second time.
I was just wondering if you could give more details.....on your hops plant, do you see any "spit-bubbles"? Where do you usually find these insects? Located on the main leaf veins? etc.
At first, I thought the insect in your picture also resembles a scale insect larvae, but it looks like it has wing buds, so I thought it might more resemble a spittle bug or leafhopper larvae. For these guys, their 'nursery' often looks like "spit-bubbles" on the host plant.
Thank jbron and ellsie. I'll take a better look tomorrow if I can see spit bubble but I don't think I saw those. There don't seem to be a lot of critters too. There's some holes in leave and color fading but thinking about it I'm not sure I'll give a treatment now. It is, the buds are coming and I don't want to ruin my harvest.
The spittle bug froth is a clear sign for spittle bugs (Cercopidae).
Other contenders include treehoppers (Membracidae) and leafhoppers (Cicadellidae) - neither group produces spittle foam around the feeding nymph. Both groups like the spittle bug are solitary not like aphids which generally occur in groups/clusters/colonies...
It is not an aphid as it lacks the 2 abdominal cornicles that aphids have.
