Talk:Bark beetle

Underrated

There are several deficiencies in the article, including grammar and bias. However, the biggest deficiency is that this is an important article that has not been given adequate attention. The bark beetle is devastating the Black Hills of South Dakota or Paha Sapa. See http://www.bhfra.org/mountainpinebeetles.htm http://www.ext.colostate.edu/pubs/insect/05528.html http://www.nationalparkstraveler.com/2010/03/mount-rushmore-national-memorial-drafting-plans-fight-bark-beetles5447 The beetle is destroying significant portions of the Black Elk Wilderness and Custer State Park, home to such distinctive features as Needles (Black Hills) and Sylvan Lake (South Dakota). http://www.fs.fed.us/r2/bark-beetle/images/sdphotos.pdf The problem is magnified by its duration, the beauty destroyed will take generations to replace.

Predators

How about a section on predators? —The preceding unsigned comment was added by 83.138.136.92 (talk • contribs) 00:38, 4 December 2006 (UTC).

Bark Beetle Predators Bark Beetle predators (Question asked on the original page): Bark Beetles are predators of trees, preying on coniferous trees such as longleaf pines. As they prey n these trees, they accumulate millions of dollars in timber damage[1][2] by creating tunnels within the bark of these trees. These tunnels began to cut off the food supply such as the xylem and phloem, and the water [3]supply the tree needs to survive. But these predators don't just prey on one tree, they move based on a chemical signal from a female bark beetle, which they become alerted by, and began to attack and cause damage to millions of trees, damaging trees stand after tree stand. However, the predator of these coniferous trees, the bark beetle, also has a predator, leaving them to become the preyed upon[1].

Bark Beetles are prayed upon by birds such as woodpeckers[4], beetles such as the black-bellied clerid (Enoclerus lecontei)[5], flies such as the long-legged flies (Dolichopodidae)[1], mites such as the Phoretic mites [1][6]. The phoretic mites are more than just a predator of the bark beetle, mainly preying on the larvae. Phoretic uses the bark beetle to move from one location to the next.[6][1]

As prey, the bark beetle pheromones used to attract other bark beetles become kairomones[7] to their prey. The pheromones distinguish as kairomones are hormones, pheromones, or allomones of bark beetles, which in turn is used as a locater by prey that is attracted by it, which directs the predator to the back beetle. (flies).[7]

Pictures?

A bit heavy on the repetitive pictures of trees and lacking of any beetle pictures. —The preceding unsigned comment was added by 64.75.187.195 (talk) 01:14, 31 March 2007 (UTC).

I have rearranged the pix to make it more pleasing layout-wise. The problem with the actual beetles is that they are so tiny! So good pictures are rather rare. I'd suggest that when the article is expanded with a discussion of systematics or diversity or whatnot, it might be better to add pix of the actual beetles if enough are available. Maybe remove the gallery with the feeding traces for thet. Dysmorodrepanis (talk) 04:08, 8 July 2008 (UTC)

'Galleries gallery'? Is this a typo? It seems redundant. Sigil VII (talk) 18:49, 14 November 2008 (UTC)

Actually no - it's a gallery of photos of bark beetle "galleries" (which is the name of these regular feeding trails) :D Dysmorodrepanis (talk) 12:03, 8 April 2009 (UTC)

Here's an interesting image. http://earthobservatory.nasa.gov/IOTD/view.php?id=36216 —Preceding unsigned comment added by 174.39.162.229 (talk) 17:36, 19 December 2008 (UTC)

Tone

Could someone who knows a bit about it rewrite this part with some content?
In the Western United States, bark beetles are attacking pine forests. And scientists are striking back. Scientists took slices of infected pine trees to their labs. They watched the beetles work. They recorded sounds made by the beetles. Then they loudly played the recordings back to the beetles. The sounds really bugged them. Male bark beetles did not behave normally. They became vicious. They actually killed females. "This is a promising line of attack," says Dr. Wufila Gronenberg. Loudspeakers could someday be far more effective than bug spray. citation needed.

From the story behind it, I suspect there is a peer-reviewed source we can use. Dysmorodrepanis (talk) 00:10, 11 October 2011 (UTC)

Scolytinae vs. "Bark Beetles"

I think it's a bit confusing (if not inaccurate) to redirect Scolytinae to bark beetles, and treat the latter term as inclusive of the taxon as a whole. Although members of the subfamily are often referred to broadly and informally as "bark beetles," it contains some taxa that are not phloem feeders, such as ambrosia beetles and even some fruit/seed borers. Although some brief mentions of these other guilds are found in the article, many of the statements in the Ecology section are true only of the phloem-feeders. Perhaps we could have a separate article about Scolytinae as a whole, and keep this one as exclusively about the phloem-feeding scolytines? Eickwort (talk) 20:44, 12 November 2019 (UTC)

Alternatively, we could keep it as is, and just edit the content to distinguish between the different feeding guilds. I'll start working towards that.Eickwort (talk) 00:29, 14 November 2019 (UTC)

Toxicity of "Bark Beetles"

I will be editing/ adding information on Bark Beetles of North America. I will include the name of bark beetles, it's chemical toxicity, how they communicate with it's community, and how they destroy forest. I will also provide link created by sources such as the U.S.D.A. Forest Service who has created pictured documentation of bark beetles, and pre-reviewed papers to support information presented.

I found this article to be very interesting! The Conotrachelus posticatus is also a true weevil species just as the one in this article. Here is more information about that same beetle: https://en.wikipedia.org/wiki/Conotrachelus_posticatus (E.kidest) — Preceding unsigned comment added by E.kidest (talk • contribs) 04:35, 28 April 2024 (UTC)
