Asparagus Beetle aaagh!

[spectrawax8]

I've just finished squashing about 50 - 60 of the (luckily) brightly coloured sex maniacs ( lots of couples) but I believe the next step is a grey grub? Is this right. any advice?
The whole things been a bit of a shock as the pests have managed to strip about 8 fronds which go yellow dry and die (like ringed trees), considering that its taken 3 years to get a crop (delicious).

I've never seen the grubs - you can see the little black eggs on the stems. I think the grubs eventually pupate in the soil. The next generation overwinter in the old stems which is why you need to cut the foliage down in the autumn and preferably burn it.

I feel your pain. . .usually in my back where I crouch over the plants trying to spot the beetles, but so far this year it hasn't been too bad down here. We had a monsoon on Saturday so I think they may have got washed away - really need some warmth now for some good growth.

Bob Flowerdew says to leave one asparagus plant up over winter (don't cut it back) ... then in spring it will become infested with all the asparagus beetles in the area and you can burn the whole lot, beetles and all.

Ooo I'll give it a try, bit scary tho as dont want to do anything to encourage the little blighters.
Comfreyfan, you'r right about the backache, ouch!
I found a couple of neat egg rows -4in each - squished.

So thats why they always say 'cut the spears about an inch below the surface' to fend of the grubs overwintering.

By the way I just got 5 Bocking 14 cuttings for Xmas pressie (belatedly) so looking forward to making my own organic fertiliser. Are you a Lawrence D. Hills fan also then Comfreyfan?
