Edits by user has nothing to do with the Colorado potato beetle and is a clear violation of wikipedia rules. Quick glance at the user's profile would explain anti-Russian bias. — Preceding unsigned comment added by (talk) 17:39, 1 October 2014 (UTC)

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. (talk) 18:24, 8 June 2009 (UTC)

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. (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. (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 (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 (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. (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)


Just a note that there have been some recent edits [2][3] using an incorrect use of endemic for this article. The editor started some discussion on my talk page, so I'm moving it here.

In short, wikilinking endemic rather than Endemic (epidemiology) is the correct useage here. Colorado potato beetle is not a disease where the latter link would be correct, and the term endemic in the non-epidemiological sense is about as common place in invasion biology as can be. The meaning of "not endemic" here is that it is not native to the region. Kingofaces43 (talk) 19:17, 24 September 2016 (UTC)

Dear Kingofaces43, your statement saying that endemic in epidemiological sense is not applicable to this kind of beetle, but only to describe the status of infective diseases of mankind IS RIGHT!
Since that my first attempt to correct the meaning of concerned sentence EXCLUDED the misleading term and link, which are not useful in this context.
My first correction was clear and precise, avoiding "endemic" plus the link leading to geographical / ecological endemism.
For sure an alien, possibly invasive species may not be endemic to a region at same time, thus superfluous to mention at all (European states).
After 2nd reverting of yours the sentence says again, that Colorado potato beetle is endemic to Russia, where it is an alien pest animal in real.
Do you see the clear contradiction within the sentence?
I am not sure, otherwise you would have understood the meaning of my first alteration and accepted it.
The term "endemic" in turn is NOT commonly used to describe invasive organisms for usual, yet may be used casually like here:
Leptinotarsa decemlineata HAD BEEN ENDEMIC to a relatively small region comprising the state of Colorado and minor parts of adjacent states, before its inadvertent spreading by mankind around the world, when the beetle became an invasive pest animal.
Next time please do not change my correction without asking, i would have explained the meaning to you.

It looks like you're having some misunderstandings (maybe language issues) here because what you were wikilinking and saying earlier is at least partially contradicting what you are saying now. The original (endemic) should have remained compared to Endemic (epidemiology) based on what you're saying now, especially since the changes you made were even less accurate terms. It can be a nuanced term, but the usage was technically correct (native isn't the best term, but rather confined to certain regions).
I can see what the original writer seemed to with that sentence now, but what I've updated has a very different meaning than the two edits you previously made. I hope that's clearer now once you see the edit if you compare your individual edits again. Kingofaces43 (talk) 20:39, 26 September 2016 (UTC)

Stamnariophilus 21:59, 26 September 2016 (UTC) Dear reviewer, the one and only important fact is that you got the message and at last removed the inapplicable term. No matter if you may understand it for real, but please do not change without basic knowledge. I am biologist, got no "English problems" at all and do know about meaning of biologic terms - for usual. "Endemic-geogr/ecol." was useless and wrong in previous version, and i guess you do not know about the real meaning. "En.-epidemiol." might have made sense, in case it was used for all kinds of organisms, but is apparently restricted to human diseases. I was not sure about the latter fact (see my note at your talk page) thus my 2nd edit was wrong. For the next interactions: please do not undo my contribution, but do ask me for the reason. I surely could have explained why "endemism" is to be removed from the sentence, and you had learned the real meaning of the term in biological sense.
