  Pests on amorphophallus
From: David <onimua at gmail.com> on 2011.02.03 at 07:56:11(21848)

Hi folks,

Since winter has been rough I've been keeping plants inside. They've been doing well however except for one plant that seems to have been struck with an outbreak of a pest I'm unfamiliar with, and seems visibly effected (though the leaf has bent over, it's not actually limp), and the leaflets never opened fully which I think is related to whatever these little things are.

The other plants in the room have a few of them but none of them are as afflicted with it as this one. Can anyone tell me what they are and most importantly, the best way to get rid of them? I'm unsure of what methods I should use as I've got a variety of aroids and don't want to spray something that could harm them.

I've attached a couple of pictures that should be good enough to help identify them (the brownish/black specs on the petiole).

Best Regards,

Greetings David,

Looks like Aphids to me, but the picture ( at least Here on my end)

is a bit fuzzy when I zoom in.

Insecticidal soap will take care of them, or even an off the shelf garden

product labeled for aphids. You don't have to spray, use a small paint

brush and apply the product directly to the insects. It may take

a few treatments to get rid of them. You can also use Diatomaceous

Earth,as a dust, which will desiccate them.

You can also put on a latex glove and remove them, wiping them off, then apply a drench

to the leaves, stems, and pot(s) where you see them. Be sure to check all your plants, because

they can move around, and be on or in
other pots. When you have Aphids

in the garden, Ants can be associated with Aphids, since they "farm" them,

and can move them from plant to plant, taking the "honeydew" from the

Aphids as they feed off the plant, by feeding on the plant stems with a sucking

mouth part. The little buggers can cause havoc if unchecked...

Good Luck..

Michael Kolaczewski

Those are aphids, David. A little soapy water will kill'em. get some plain unscented soap and rub it under warm water in a bowel. Get it good and soapy then pour it in a spray bottle ans spray them.

I refuse to participate in the recession,

Thanks for the replies. I used a homemade mixture that seems to have worked on them, and the aphids seem to have curled up and died. Very happy they're they're gone, though I'll re-apply in a week or so to be absolutely sure.

I never thought they were aphids because I never thought there were other colors! I'm used to seeing the bright green to slightly dark green ones found on roses once in a while, hence why I didn't think these were aphids. If I knew that I wouldn't have asked.

Thanks again!

Isn't it funny...
Just about the time you think you have been introduced to all the pests...
you find a new one!
Or a new version of an old one!
I love gardening..

I tested out several different pesticides last season to deal with
aphids scale and mealy bugs. I found that insecticidal soap and neem oil
would burn leaves in sun or in hot weather. Malathion and Seven also
would burn the leaves. Out of all the chemicals we tested Orthene
insecticide showed the most promise working well and not burning the
sensitive leaves that most aroids have. It is a strong chemical and
should be used as directed. I had hoped that some of the lesser
chemicals would have worked but the damage on the crop was very
noticeable and the bugs would return quickly and in some cases never
leave. I use it once I notice any out breaks now in the greenhouses.
