Whats killing my bush????

[Ventureoverland]

Im not sure where to put this but I know there are some green fingered people out there, so thought Id ask a question...

We have just moved into a lovely house with an equally lovely garden. In the said garden is a "Silver Hills Manderin" bush (aka Citrus Riticulata 'Silverhills'). Its a nice looking bush but something else seems to like it more than me as it appears to have some sort of disease...

The pictures below show a healthy leaf and two (or many) leaves that are exhibiting the problem...

Any expert out there who could advise as to what the problem is and further, what is the solution to get rid of the problem and kill off the nasties as the plant is looking "worse for wear".

I'm not an expert on this, but look up "citrus leaf miner".

There are quite a few refs, and the pics look like yours.
Here's one: https://docs.google.com/viewer?url=http%3A%2F%2Fwww.dpi.nsw.gov.au%2F__data%2Fassets%2Fpdf_file%2F0006%2F137634%2Fcitrus-leafminer.pdf

Think Am is on the money.
Cut all the leafs that look like that off, put them in a plastic bag and then in the garbage. The plant should recover if you have to cut a lot of leafs off. Water the plant well, a couple of times a week.
Google and good luck may help you control them.

Thanks all...

I'll have a google today if I get a minute at work but will nevertheless take off all the damaged leaves tonight after work... Poor thing is going to look rather bare!!!

Thanks again
Jon
