brassica problem?

Hello, I'm new to this forum. I'm not sure if I have a problem or not:o

I have noticed that on many of my cabbages, there are a number of small weevils about 3 or 4mm long, grey with spots. They look very much like a picture that I have of a Vine weevil but I thought that Vine weevils were a bit larger than the ones that I have described. Could they be Gall weevils? These only have their grubs affects described in my books, and no picture or other description of the actual weevil. Does anyone have experience of these beasts?

Thanks

They sound more like ladybird larvae to me Stony. So they can only be good. However, a pic would be useful to make certain. Turnip Gall Weevils, on Brassicas, affect the roots, so I think it`s safe to rule them out. If you can`t supply a photo, then Google Ladybird larvae.:thumb:

 

Hi David. It's definitely a Weevil, with a pointed proboscis. I am familiar with ladybird larvae. If it was Gall larvae at the roots obviously there would have to be adult weevils to start the ball rolling I havee taken a photo and will try to download a link to it. Not sure if it will work though.

Thanks for looking at the problem.

It didn't work, not sure why but will try again later.

 

Hi David. I have now got a link that works in my post, to show a pic of the weevil, if you fancy a look at it.

Stony.

To post pics from photobucket...copy and paste the IMG tag.:thumb:

 

Thanks Tweaky, if you look at my last but one post you will see that I have posted a pic that works. Previously, I left the .jpg off of the link:o

Stony, you are right I`m afraid. That`s definitely Vine Weevil.

 

I thought that vine w' were larger than that I wonder how they will affect my brassicas? So far all crops being picked and dug in my patch are fine.

Having now looked at vine weevil pics on the web, I find that it's a much bigger beast than the many that are on my cabbages, and it has no proboscis. So I am no further foreward at the moment:confused:

I think that it may well be a Cabbage Gall weevil, but I cannot find a picture of an adult anywhere on the net:(

Stony, it wouldn`t be CABBAGE gall weevil, it would be TURNIP gall weevil.

 

Why do you say that, David? I found the cabbage gall weevil listed on the net, but no picture.
It is scientifically known as: Ceutorhynchus pleurostomus. Is that the same beast as the Turnip gall?

I've still not found a source for a picture of an adult cabbage weevil, or a turnip one either.

Anyone got a lead or an y idea's.

I do wonder, if I have not helped the situation, by putting an anti butterfly cage over all my brassicas, because that also keeps the small birds out, which might eat the pests.

Thanks
Stony

 

Stony, just had a look, and cabbage gall weevil and turnip gall weevil are, apparently, one and the same.:thumb: But I couldn`t find a pic either. Will keep looking, though.

 

Could it be a pea and bean weevil? see:
