Yet another insect question
Bought a 15yr old seemingly healthy Fukien Tea at an arts festival. 2wks later I notice a lot of sap falling from one large branch. Another 2wks later I clearly have an infestation of some small white bugs on the underside of leaves, mostly confined to the one now very sticky branch. Blasted most of them off with a water jet. Eggs look like black spots glued to the leaf undersides. There is one winged insect in the photo trapped by the sticky sap - don't know if he's just unlucky or part of the problem. Tops of several leaves have whitish deposits that look more like some chemical residue than webs. The tree seems otherwise quite healthy. Are these red spider mites? They don't look red to me.

Maybe aphids?
http://images.google.com/images?q=aphid http://forum.bonsaitalk.com/f13/und...help-25571.html http://forum.bonsaitalk.com/f7/cont...story-2242.html These are just two of many threads on fukien and aphids. Fukien tea is very prone to catch insects. Some measures when you see problems (from what I've read on the posts): 1. Mechanically remove them (your water jet, or shake the plant so they fall) 2. Soap solution 3. Repeat soap solution two weeks after Preventive (after you get rid of the problem): 1. Not too much watering, not too little 2. Systemic insecticide. I have fukien teas, and have kept them well by using the "complete solution" kind of fertilizer/systemic insecticide/disease prevention type of product made for roses.

Thanks for correctly identifying the bugs. I thought aphids were scaly but now I'm finding photos that do look like what I've got. I'll try the soap and rose products (my wife is into roses).

aphids
You might want to make sure you have gotten rid of any ants that are around the tree too. Ants actually "farm" aphids like cattle. They place them on plants and work the herd, they milk the aphids by stroking the bodies and collecting the sticky substance that the aphids give off. If you don't get rid of the ants, you will never get rid of the aphids. Of course, a good systemic poison might do the trick, making the tree poisonous to anything that feeds on it.

susieq,
I think I caught this before the ants found it - the weather here is cool enough that I've had to keep it indoors except on the warmer afternoons. The branch was covered in sticky ooze - to the point of dripping on the table - so our house must be pretty much ant-free. But thanks for the warning. I'm sure I haven't seen the last of these aphids. I do seem to have one small millipede living in the roots that I haven't been able to kill, but so far I can't see he's doing any harm (maybe even good?). |
