If you're concerned about using pesticides, an alternative solution
might be to place pheromone containing japanese beetle traps some
distance away from the hops (preferably on your neighbor's property
8-))

You have Japanese beatles. The only method I know to get rid of them is to
spray your hops with Malathion or Thiodan. Either one is very effective at
ridding your plants of these critters. Follow the label directions
carefully.
