Went to a seminar detailing this bug today and half the avocado growers in Southern Cal were there along with many pesticide applicators. Do a search, 286 known tree species it's gotten into so far. The one found in LA County is genetically different than the one recently found in El Cajon. AND...it is no bigger than a sesame seed! It was not an uplifting seminar.

Mats, I guess I'm an inert blob for appreciating a little spoon feeding now and again.

I still love ya Davey m'lad!

So far palms are safe. One of it's main hosts is, of all things, is Castor Bean.

Avo growers cannot use a systemic pesticide for apparent reasons,ie; the fruit.

The critter bores it's holes through the cambium and deposits a strain of Fusarium, which it retains in it's mandibles, along with it's eggs. The eggs hatch and the larvae feed on the Fusarium, spreading it throughout the host via the various galleries they have bored out.

I'm no doom-sayer but this guy stands to make the RPW look like an amateur.
