To some extent. Hard winters reduce such things.

But living in a town makes more difference. If there aren't enough
of both the winter and summer hosts in the vicinity, there won't be
a permanent blackfly population. Same as for malaria.

Are you saying that towns make for more or less hostile condition for
blackfly?

More hostile for the blackfly, in general.

Thanks, that's encouraging :-)

I've never grown broad beans before but mine, sown in March I think, are
now about 8" high with lots of flowers.

There's no sign of blackfly on them but I'm sure I've heard something
about nipping out the tips being a preventative.

What's regarded as the tip? A couple of leaves or the lot above the
flowers?

What's the purpose?

TIA

Just found the packet, they were Suttons and dwarf. Pinching out the tips
was suggested as a blackfly prevention.

Should have read the packet first, innit!
