Hello Val.
I have been gradually converting some old pasture land into a no-dig garden over the last few years and had some problems with wireworm. I haven’t used any treatments, or grown any crops to try to reduce them, but have found that they do become less of a problem over time. I’ve found that thay were most damaging in the first year, but were much less of a proble from the second year on.
I now grow vigorous plants – usully squash or courgette on land just converted from pasture, then use it for other crops in subsequent years. The curcubits grow so fast that the wireworm don’t seem to damage them at all.
