Can carrot fly affect other veg?

[Normans Mum]

Hi all
Recently pulled some radishes, which I had planted inbetween onions. On slicing them have found small white maggots in the centre of all of them. Could it be carrot fly as maggots are very small, or could it be onion fly ? If so will my onions be affected as well ?

Very interesting. Thank you, MIkey

Probably flea beetle grubs. They will attack any brassica. I think carrot fly will attack parsnips.

Cabbage root fly will attack any brassica. Radish,turnips,swede,cabbage,kale sprouts.calabrese and wallflowers and of course their favourite cauli's.

Probably missed out quite a few also, but you get my point!

Could it be carrot fly .. or could it be onion fly ?

Nope, radishes are brassicas.

It's cabbage root fly larvae, they do my radishes so badly that I've given up trying to grow them.

Flea beetle larvae are teeny tiny "delicate and thread like" and feed on root hairs http://richland.uwex.edu/files/2012/07/Flea-Beetle.pdf

Even though they're brassicas they're only a short term crop so I grow them out of rotation in with my parsnips and carrots which are enviromeshed throughout so no worries there - slugs however are a different story.
