Please use second-level headings[edit]

The Manual of Style indicates that headings should start with "==" (i.e. they should be second-level headings), not "===". Thanks! --Diberri | Talk 22:38, Oct 5, 2004 (UTC)

OK, no problem; my thinking was that "==" headers were a bit heavy given the relatively small amount of text, ref. the notes in the Manual of Style "Overuse of sub-headings should be avoided, as it can make the article look cluttered. Short paragraphs and single sentences generally do not warrant their own sub-heading" and "In circumstances where there is not enough text to justify a sub-heading, it may be preferable to use bolded text or bullet points within a section instead of using sub-headings" - MPF 10:24, 6 Oct 2004 (UTC)

Is map correct[edit]

If the origin of the beetle is Mexico, why does the distribution map show it as the Colorado state? jrbray

The center of origin is not known for sure. Colorado was one of the first places it became a problem, so that't why it has the name. 119.202.90.110 (talk) 18:24, 8 June 2009 (UTC)

Identification[edit]

DirkvdM coloradobeetle.jpg

Because of the stripes I thought this might be a colorado beetle, but the red head doesn't fit. If you recognise it could you add any info to the photo's page? Thanks. DirkvdM 18:32, 31 August 2006 (UTC)

This is not a CPB. CPBs are much wider and taller relative to their length (compared to this beetle), and the lack of 10 stripes (decemlineata) is a dead giveaway. 149.4.203.111 (talk) 20:10, 6 May 2009 (UTC)

Natural enemies[edit]

Does this bug has natural enemies: birds/other bugs that feed on them?

No significant ones. CPB sequester toxins from their host plants, and are therefore toxic themselves.119.202.90.110 (talk) 18:22, 8 June 2009 (UTC)

Ambiguous slash[edit]

Does "yellow/orange body" in the lead mean "yellow-orange body", "yellow and orange body", or "yellow and orange body"? If someone knows which it is, please edit the term. Even if it's some combination of those possibilities, it can be clarified. (By the way, maybe the answer to my question is obvious from the picture, but I have deuteranomaly.) —JerryFriedman (Talk) 03:58, 3 May 2009 (UTC)

"Life Cycle"[edit]

Someone deleted all contents of this section, leaving an orphan header. I have reinstituted the information. —Preceding unsigned comment added by 119.202.90.110 (talk) 18:29, 8 June 2009 (UTC)

Natural diet?[edit]

Obviously this insect is most notable to us as a potato pest, but based on the maps it seems its natural range, and the original range of the potato, do not overlap. Did the potato naturally spread from South America into SW North America, promoting the evolution of a new insect species in these "colonized" areas, or did the "potato beetle" actually predate the arrival of potatoes in this part of North America? If so, what was its principal diet and lifecycle before the establishment of potatoes? —Preceding unsigned comment added by 65.12.128.24 (talk) 22:38, 16 July 2009 (UTC)

Source for Soviet satellite propagada[edit]

I found a Czech propaganda video that discusses how potato beetles purportedly came to Europe by way of American Air Force planes.[1] Not sure about dating of it, I'll have to do some more digging. 207.172.208.89 (talk) 14:02, 7 August 2010 (UTC)


Tansi as organic insecticide[edit]

The following information would be good for the potato beetle page. I am not sure what would be the regular way to refer to it. If anybody could do it I would be happy: On the "Tansy"-page under the headline "Organic insecticide"i found:

Tansy can be used as in companion planting, and for biological pest control in organic gardens and sustainable agriculture. It is planted alongside potatoes to repel the Colorado potato beetle, with one study finding tansy reduced the beetle population by 60 to 100%.[1][2][3]

Is it endangered?[edit]

I used to see this insect every year in Ohio on our potatos when I was a boy. That has been 30 years ago and I haven't seen one since. Are they extinct in Ohio now? — Preceding unsigned comment added by 2602:306:C518:62C0:2450:24EA:EA5F:BE0D (talk) 05:04, 16 June 2012 (UTC)
