The next phase of their life is to turn into beetles (round about now), where they will then proceed to climb back up my tree, have some more leaves, lay some eggs.... then there'll be more grubs that will eat more leaves, then climb back down the tree into the soil by the roots, where they'll turn into beetles.... I don't know how long they've been getting attacked, but they're not healthy trees and sustained stripping of their leaves every year can't be good for their health I would think We have horses and heap the stable litter under the Elm trees. The attacks are minuscule (hardly at all), which I am told is due to the horse poo. Next door's Elms were attacked normally.

Also just found that there is a parasitic fly that has been tested at Agriculture Victoria’s Keith Turnbull Research Institute against native and beneficial insects and was found to only attack elm leaf beetle larvae. Not sure if it's available as yet. How pricey is it to buy beneficial insects and do you have to buy in bulk?! :S A survey must’ve completed by a certified surveyor. This form part of every DA requirement 3 224536 Thanks for the insights, that makes perfect sense, and yeah, I will be leaning on the experience of the excavator operator entirely. 6 16322 I want to build a bigger driveway (without a nature strip) than has been approved under my CDC. I’ve also had a DA approved to build a deck. It looks like I can do this… 0 4845 |
