Brace yourself, this is gross- White fly- SON OF A GU!!!!
 

so i garden a lot at night. as a result i wear a headlamp and have a very narrow scope of vision as i move about.

last couple of days i notice that the leaves of some of my Catesteums were dirty. i rubbed them gently and they got a bit cleaner and i figured the roof was really dirty and i should maybe pressure wash it. I went last night to peek at the roof and, lets just say i found the problem before i got on the roof.

White fly!!!

this is the palm tree above them. UGH.


so the need to go and the plants need to be cleaned...any tips


i was going to make a sprayer of ISO and a bit of Palmolive and use that for the flies....plain soapy water for the leaves?

here are the dirty plants...it is gross, not for the squeamish

Soap for the palms... are you SURE the Catasetums don't have spider mites? That's exactly what they look like with spider mites.

I have never heard of a spider mite in my humidity


What else do I look for?

not spider mites.

i just checked after a quick google search, no bugs, no webs, no damage...the leaves are just covered in the black fungus that comes from the white fly honeydew (vomit) i sprayed the whole tree with doc bronners in a gallon of rain water and tthen scrubbed a bit at the Ctsm. leaf and it cleaned up but not easily....

fun new challenge

and here you can see where i rubbed a bit off and the leaf is otherwise unscathed.

my fear is hat this is the same as growing them in a LOT less light bc this must interfere with photosynthesis and probably respiration too

oh geeez. Looks like I won't be having dinner tonight.

Some fumigation of the out-of-control white flies needed. Some systematic treatment maybe.

that's interesting SP...i did not know white fly COULD be treated systemically...and how does one ensure uptake in a TREE?

googling away...….thanks!

DC ----- I think that imidacloprid can be quite effective against white fly, but unfortunately ultra nasty for bees and maybe other animals too. I think spraying enough if it on leaves can do the trick too. But bad for bees! Carbaryl could probably work too against white fly - or at least really control their population on those leaves.

Is that white flies or mealie bugs?

If the palm tree doesn't produce anything that needs pollinated, you can use a systemic. If it does, I would use Malathion (a contact pesticide). Just follow the safety instructions and do not spray anything that is being pollinated by bees. Neem oil would take care of the problem after a few applications and it is quite safe.

i was thinking neem- i hate the smell and id have to move the orchids under it but its safe...

it is a coconut but immature...i will avoid systemic

white fly...when i sprayed them with a hose there is a cloud of flying disgusting that resettles back in the same places...not mealy behavior

Good luck. I was lucky last fall that I caught Whitefly early and the Neem oil took care of it.

Pesticide spraying is problematic for white flies because the generation time is so short they rapidly become resistant. Palm flowers are magnets for bees. In addition it probably won't help much because it is practically certain all your neighbor's trees have the same thing. They will come right back.

Take a piece of leaf with live larvae and adults to your neighborhood ag extension, or university biology department. They can probably advise as to predator insects to release. That is a much better approach with a very large outbreak like this. The predators may remain as a viable population in your area because the white flies are probably never going to be eliminated completely.

Lady bugs and lacewing larvae are good predators of whitefly. I release lady bugs and, usually set out the little paper bags of lacewing eggs, every spring to clean up my plants. The lady bugs usually lay eggs before flying away but this year, they stayed on my plants for some time, first.

I am pretty such that I can buy lady bugs at butterfly world. On it!

Thanks, gents!

DC- consider a concentrated azadirachtin product like Azamax instead of neem oil.

I’ll look into it. Thanks
