Red Lily Beetle
I've got these. I realised I had them last year when I found them
growing on the fritarillaria meleagris. I wasn't too fussed, however, because the lilies seemed to survive, and didn't become too ragged. I drowned the pair or two that I found. Yesterday, however, I caught thirteen of the monsters, in a different part of the garden (the fritarillary seem to be OK this year) and drowned them all. I have a trough planted with lilies that I have been meaning to replant. Not sure of the exact sub species. The majority of the beetles that I caught were on chives, actually, but chives that were in very close proximity to some legacy lilies that I inherited when I bought this house, not exactly sure of the sub species there. These lilies already have very ragged leaves. I cannot, as yet, see any trails of eggs on the underside of the leaves. I have been meaning to unpack and replant this trough - it is replete with bulbils and stuff. I had been meaning to plant up some bulbils in a smallish pot and pass them on to a friend of mine. I would like some advice as to what I should do next. I am tempted just to chuck all the lilies, get rid of them, no more lily beetle, haha. I have just done fairly extensive research, and this group, amongst others, has reccomended Provadol (?), Malthiol, and Neem. Also, people have said that catching the beetles and larvae and killing them eventually brings the numbers down. What I want to do is unpack this trough of lilies, repack some of the grand old ladies (untouched by raggedness, at leas this year), dump the compost into land refill, along with unwanted bulbils, repack, and then either apply Provadol (?) or Neem (malthion is a nono from having googled on it) or just do the hunting thing, and maybe dig up and chuck out the legacy variety that apppears to be most strongly affected. And I'm just wondering whether or not this appears to be a reasonable thing to do. Am I likely to kill or reduce the infestation this way? I caught 13 of the beetles yesterday, and one got away. With regular inspection, and a repotting so that they are less crowded, along with an application of a fairly beneficial insecticide for a couple of months, am I likely to make a difference?

Glenys Sounds a reasonable solution Glenys. I get them too on my lilies but picked them of and destroying them seems to work for me. You just need to be vigilant and keep at it. By killing them of now you might prevent them from laying eggs. The RHS has a lot of info on them and a research program: http://www.rhs.org.uk/advice/profiles0500/beetle.asp Jenny |

Are these the ones that drop off when you go near so that you put a sheet of greased paper underneath to catch them?? -- Jane Ransom in Lancaster.

Except that I have been putting a jam jar lid underneath and then tipping them into some soapy water contained in the jam jar. Looking at the grey grey outside. I really need to go out and sort these lilies out now. Another cup of coffee, first.

Digging up all your lilies sounds a bit excessive to me. Lily beetle can do
a lot of damage in a short time, but with regular inspections you can keep the numbers down. I had been simply squishing them up until last year, but my Dad suggested a product called 'Bug Killer' which really does seem to keep them at bay. Regular applications of this spray at monthly intervals should do the trick. Neil "MissJuggs" wrote in message ... I've got these.
