What you originally described didn't sound like whitefly to me
Henry, what did it sound like? I am slightly farsighted, but it is not
yet bad enough that I need glasses. They are snowy white--looked to me
like the larval state of white fly in some of the photos I saw.
The first thing that came to mind is a woolly psyllid which is a sort of
cicada like insect but much smaller. They are jumpers and have a white,
cottony, powdery substance on them. there are also a few woolly aphids
(Paraprociphilus or Prociphilus species). Whitefly don't so much jump
as take wing and fly. Psyllids jump somewhat like leafhoppers (although
they fly after jumping). It's hard to tell by a short description so if
you've found pictures that look like what you have, I'll let it go at
that. Whitefly have a white powdery substance on them but nothing like
what these others have. Not what I'd describe as "snowy fuzz."

but if
that's what you have, they are more of a nusance than anything and
should be killed by your Orthenex.
Just as soon as I sprayed today it rained--and the sky was not even
overcaset. I am so scr*wed. Or, rather, my roses are. It was supposed
to rain every day this week EXCEPT today.
I hate it when that happens. We've gone a week without rain here
(although it rained 20 minutes from here last Friday). The roses are
enjoying life, actually. Auguste Renoir is having its second flush.
When you consider that NOT ONE BLOOM opened on the first flush, you'll
understand how much that means. Pat Austin and Johann Strauss are
getting ready, Linda Campbell is putting on lots of growth which means
the flowers are coming. Of course, there's plenty of black spot to go
around. Sprayed Saturday. Will again this weekend (weather permitting).
Sevin will work on them, too.
I was surprised to see Sevin mentioned here, because it was one of the
first things I used on my roses for insects and one of the old crew
blew me out of the water for it. Might have been Mack, in fact.
Well, I suppose it is worse than some things, better than others. Must
have been before I started reading the newsgroup. I'll do a Google
search and see what was said.
Yes, Sevin (carbaryl) does kill Japanese Beetles and is often the
recommended insecticide for them. But remember that it is not a
systemic - it is not absorbed by the plant. Beetles (and other
insects) have to ingest it directly off the leaves (or absorb it through
direct contact (i.e. be present when you spray so they get hit with
it). Anything more than a light rain will wash much of it off. It is
not nearly as toxic to vertebrates as Orthenex (WARNING - handle
according to the directions on the label!).
I use goggles and a respirator, gloves, long sleeves. Very
uncomfortable, but better not to take a chance.
Yeah, me too. These are all designed to kill things. They are all
toxic to a greater or lesser extent to humans. Precautions are warranted.
Because the name Sevin is a registered trademark, you'll have to look at
the active ingredient of insecticides to see it this is what they use.
Ortho, for instance, has carbaryl packaged under the name "Bug-B-Gon (R)
Lawn & Soil Insect Killer with Grub Control" but other Bug-B-Gon (R)
products use other active ingredients (Esfenvalerate or Permethrin
mostly). Again, read the entire label of whatever you buy.
Good to know. I have some Bug-B-Gon out there somewhere.
Just be sure to check the active ingredients.
