This was my Screw Pine or Palm Pandanus tectorius last year at 6 November 2013. I grew it from seed which germinated in 2005.
Since then this healthy palm started to go downhill. It was only last month that it occurred to me that it might have the Pandanus Leafhopper infection (Jamella australiae). This leafhopper is native to North Queensland north of here but has been introduced to Southern Queensland and Northern New South Wales where it is devastating groves of this iconic species. The problem is that it is kept in check in the north by a parasitic wasp which is not present in the south. You can read about the problem here where a local authority is battling to save their Pandanus.

There is a picture of the leafhopper here. It is about 8mm in length.

Here, I am going to detail my attempt to save my palm over the coming months by cleaning up the foliage and injecting a systematic insecticide into the trunk and branches.
