Hazelnut Weevil (again)
« on: September 08, 2018, 11:32 »
This is a cut and paste from a post at about the same time last year that didn't get any replies. Am posting again because, unfortunately it's just the same this year - and I'm still none the wiser! Perhaps someone can help.

"The hazelnut crop looked really good this year. I try and pick the nuts before they fall in case they have the maggots/larvae of the hazelnut weevil in them. This is worse some years than others, although I can't work out why.
If it's a bad year the maggots tunnel out of the nuts, burrow down into the soil and pupate and emerge the following year to re-infest the trees.

Despite my best efforts with this, and also repeatedly raking the soil to expose any to birds etc. over the winter/early spring, it seems that there are lots of nuts with maggots :(

Does anyone have any advice to offer that I might try? Thanks."

Is it worth covering the soil under the tree, so the maggots cannot get into the soil/the ones already in the soil can't get out? Other than that I've no idea :(

Do you know when the weevils fall to the ground, if so you could put cardboard down  in the same vein as mum but then burn it to destroy them

Thanks to you both. That seems a good place to start. And I don't know why it hadn't occurred to me to try?      ::)

I've done a quick internet search for the pest.

Here's an article about the life cycle of the weevil, and here's the Wikipedia page with a little information about control (it references chemicals and nematodes).  I haven't looked to see whether either option is available to amateur gardeners in this country.
I try to take one day at a time, but sometimes several days all attack me at once...

Thanks for the link Yorkie. Interesting reading. Ema, thanks for the idea. Chickens might help with the weevils but could present their own complications!
