Couple of insect ?'s
 
So tonight i looked through my two cascade hops plants. I found a few baby praying mantis's and a few spiders, so that's cool. However I found some things I'm not sure of. I found a few small katydids. I've researched a little and get conflicting info on whether they will do more harm than good. Any insight?

Also I found some of these little buggers. Not sure what they are, but they look like they're carrying little pieces of cotton around, most likely some sort of web for eggs. Any insight here? I'm thinking about capturing the praying mantis's and keeping them alive, spraying with insecticide tomorrow and moving forward. Good idea or bad idea in your opinion? FYI I'm in Central Ohio.

That looks like some kind of mite.

Unless you see any damage on your plants, I would not be too concerned about it.

Problem solved, er, at least identified.

Two striped planthopper in nymph stage.

Appears to feed on plants - not good for hops. Appears Sevin does not affect them as i drowned one in Sevin and it didn't even slow it down after a few hours. On to imsecticide level bravo! :rockin:

I'd be careful with the insecticide. You can't use very strong pesticides, as you'll be consuming the hops. I've been told insecticidal soap is just about the strongest you really want to be using to spray them.

DO NOT treat your plants with insecticde for leafhoppers!!!! Here are just some reasons:

1. They do practically no damage! (A few dots on your leaves is not even worth worrying about)

2. They don't leave your plants with sooty mold like aphids do.

3. When you spray them, they just fly somewhere else.

4. They are a roaming insect, and the whole population from your neighbourhood will just replace whatever you kill.

Seriously, it is just not worth it.

I've lost 4 tips off my bines the last week or so. So these are not the culprit? 2 have been completely chewed off to the stem and the other two basically just dried up and stopped growing.

BradleyBrey, no they are not the culprit for that kind of damage. Leafhopper are in the Homoptera insect order, which means they have piercing/sucking mouthparts, and physically cannot chew plants. Keep looking for the actual culprit.

thats what I thought... hmmm I found a few dead beatles on my big chinook hop leafs where I have begun to spray. Maybe they have been dining on the tender parts of the plants.

It looks like rooispinnakop (red spider mite) acarsten flo or steward works well as a spray on commercial level
