"Let me just say I don't get them in my garden, but a place not too far away where I volunteer has them by the millions. I let the dill and arugula go, and several plants in the yard attract beneficials and they seem to keep most critters at bay. Dan" I do have lots of dill flowering - great for making pickles too :) I did have cilantro flowering - but I harvested the coriander seeds for spices and replanting. There are some kale and radishes flower....also a lot of oregano flowering... Interestingly - I just peaked into the yard to see what was flowering - and there was a group of sparrow (or look like sparrow birds) sitting on various supports near the cukes. Every so often, one would dart into the cuke vines.....they were hunting something.... research says sparrows are primarily seeds and occasional small insects, so hopefully the are feasting or at least snacking on these CB. In the 5 days since the OP - I haven't noticed much of a change in the cukes, still harvesting daily, I'm thankful to say....volume is down, but then temps are too so I think that is expected.

I'm having the same problem on my cucumbers and zucchini here in MA. I started picking them off after sundown with a headlamp on (they can't really see me coming and just sit there, easily picked off) and then again in the early morning when they seem to be slow from the cooler nighttime temps or something. I'd been doing this for about a week and noticed that they kept coming in greater numbers. Finally, I had enough and just last night after sundown, I sprayed the leaves with a product called Bon-neem. It's an insecticidal soap with neem tree oil that is diluted with water and sprayed on. I checked the plants this morning and saw only two beetles that were scurrying around the leaves but nothing close to the number I had before I sprayed. I am either going to try to spray some more if the numbers increase or try spraying some rotenone, which I heard works well. My biggest concern is that the plants will get infected with bacterial wilt and so I am not totally sure if I should be trying to zap them all or if it's okay to have one or two still around.

The steps in Integrated Pest Management are, 1. Identify the problem, (which you have done) 2. Determine if a control is necessary. (also done) 3. Determine the least toxic, least environmentally harmful, means of control. 4. Apply that means of control. 5. Review. So you have a problem, the Stripped Cucumber Beetle, in fairly large numbers and since they are on the plants Floating Row covers would not help at this time. Next would be are there predators present in large enough numebrs to control the buggers and if not what would be next? Would Insecticidal Soap work? If that did not then maybe Neem Oil products. If that did not work then maybe a pyrethrin product. And for next year plan on placing the Floating Row Covers when the melons are planted as well as making sure you have a good, healthy soil to grow them in.

Pollination is a problem, but I think the main problem is that no flowering is even taking place to begin with. Interesting update on the situation - I mentioned that until yesterday I had only seen 1 striped cucumber beetle, and then killed 3 in the morning... well I went out on my nightly slug hunt last night and ended up squashing about 10-12 more SCB's, 6 of which were coupled up and going at it on the leaves. Rest assured I busted in like a disapproving father and brought an end to their shenanigans. No signs of any eggs this morning, and only one more single beetle seen/squashed. SCB damage to the leaves seems very minimal... no wilting going on, but still no flowering :/
