wrong order - balance[edit]

This article leads off with issues/problems with Biological pest control. It should start with more of a useful description of the topic for people who want to know about the subject before the soapbox is mounted. Yes there are problems however the use of biological controls is generally more environmentally concious than chemical control methods.

people keep mentioning ladybugs as a bio control agent, however i have heard that ladybugs are rarely used as a weevil is a lot more efficient. is lady bug the best organism to be talking about then?--Hypo Mix 08:27, 10 November 2007 (UTC)

Convergent ladybeetles (Hippodamia convergens) are the most commonly available insect sold in garden centers and nurseries in the US. I am not familiar with a weevil being used or a weevil that is more efficient in any type of bio control. Most weevils are plant feeders unless you are referring to a type of assassin bug which have very general appearing mouth parts, such as the minute pirate bug (Orius spp.)Bugguyak 11:26, 10 November 2007 (UTC)
might be an Australian thing... just so long as they are commonly used in the US —Preceding unsigned comment added by Hypo Mix (talkcontribs) 02:34, 12 November 2007 (UTC)
Many weevils are used in the biological control of weeds. I don't know of any that feed on insects or compete with ladybugs for prey.botanybob 23:38, 12 November 2007 (UTC)
i think i got the weevils part wrong, but i remember a lecturer saying something about an insect being more effective than lady bugs and therefore ladybugs being not commonly used, but it might be an Australian bug in which case it wouldnt be sold in the US (unsigned)
I've heard of ladybugs being used to control aphids (and have done so), but never weeds. (talk) 05:28, 14 July 2010 (UTC)


Most of this article (including pictures, formatting and references) is directly lifted from an article on the subject. article Dr. Root 19:49, 11 March 2007 (UTC)

I checked on this reference and it appears that the search engine at was simply referencing the wikipedia article on the subject, thus it is a copy of the wikipedia article rather than the other way around.--botanybob 20:53, 20 September 2007 (UTC) bffdbfdbfgdzfgvcdmjcghmgchmch

adverse effects?[edit]

What about the adverse effects of introducing species/ diseases as biological control? I think a section on this would be useful.

Done. Could be expanded though. Hope this helps. Bugguyak (talk) 12:37, 8 December 2007 (UTC)

I fixed the external link to the Cane Toads page so it now points to the intended page instead the ever-popular 404 (talk) 23:46, 4 October 2009 (UTC) This stuff i plagirized — Preceding unsigned comment added by (talk) 17:49, 20 March 2012 (UTC)


"It has a tapering segmented grey/black body with orange/yellow markings nettles in the garden and by leaving hollow stems and some plant debris over-winter so that they can hibernate over winter."???

expand context for this subject[edit]

Biological control is used and studied in a much wider context than organic gardening. For example, it has become the standard method of pest control on several commercial greenhouse crops such as tomatoes. It is also the subject of a large body of research work in applied entomology. As someone who works and has done research in this field, I found it odd that the introduction to this article is actually about organic gardening. It seems to me that the introduction should be about biological control in general, and its use in organic (or non-organic gardening for that matter) should be given as an example.

I agree that this article needs to be expanded in order to be accurate. There is no mention of the types of biocontrol, such as conservation, augmentation, and classical biological control.--Bugguyak 17:43, 13 May 2007 (UTC
What stood out to me, was the small amount of information on the use of biological control to control invasive species by introducing a predator from the invasive species' original environment. I don't know much about the subject, but UC riverside has a wealth of information on it. (talk) 05:34, 14 July 2010 (UTC)

Microbial biocontrol section needed[edit]

There is one mention of the fungus Trichoderma on the page. Should also be linked to Entomopathogenic fungi, Beauveria bassiana, Bacillus thuringiensis (Bt), and others. Nemetona 18:02, 26 May 2007 (UTC)

See biopesticide Roy Bateman (talk) 17:34, 19 August 2012 (UTC)

History and development of biological control section needed[edit]

It may also be useful to have some background information on the history of and development of biological control. This will help establish the scientific basis of this field. Some mention should be made of Paul DeBach's work and his colleague's and students. He was very influential in developing the field based on good scientific and technological foundations. For a brief summary of his work see Paul DeBach Trebot 17:13, 23 June 2007 (UTC)

Plants section comments[edit]

I do not believe that this section is well tied to the topic of biological control. Initial bullets are good, but the list of pest-repellant and deterrant plants goes beyond the topic. The effectiveness of this approach is highly questionable and methods are poorly documented. I would like to remove the table from this section and focus on the use of plants to provide food and habitat for beneficial organisms. Any other thoughts? --botanybob 21:47, 20 September 2007 (UTC)

Good job. I support this. Bugguyak 23:16, 20 September 2007 (UTC)


I think there is a mistake on references. The article of Collier et al. 2003 is more an article of T. Collier et R. Van Steenwyk -2004- A critical evaluation of augmentative biological control. Biological Control (31): 245-256 —Preceding unsigned comment added by (talk) 14:44, 7 March 2008 (UTC)

I removed "Other fungi ... evoke stress response of the plant facilitating further plant defence reactions.[citation needed]" - agree citation needed Roy Bateman (talk) 17:32, 19 August 2012 (UTC)

Pleasantly surprised to see our website listed as a reference in Wikipedia! But we have formally changed our name and web address.

Rabbit Haemorrhagic Disease[edit]

I am looking for some reviews for the article rabbit haemorrhagic disease. Thank you! —Preceding unsigned comment added by Lisakauth (talkcontribs) 17:22, 6 April 2008 (UTC)

Looks good! Thanks for putting in some hard work. By the way, you can sign with four tildes. OptimistBen (talk) 20:59, 10 April 2008 (UTC)

Copper oxide chloride[edit]

Copper oxide chloride also seems to be used frequenly as a (semi?)-biological pest control agent. Please include

Biological control is typically defined as the control of pest populations by use of living organisms or viruses. A chemical treatment wouldn't fall under the category of biological control since there isn't an organism involved. Kingofaces42 (talk) 01:38, 29 March 2012 (UTC)

Octopamine physiological effect in humans[edit]

Octopamine is considered an exciting target for new insecticides primarily because for many years it was thought to be absent in vertebrates. This leads most researchers to jump to the conclusion that it is not effective in vertebrates. However, this does not necessarily have to be the case. Several review papers discuss octopamine's watershed dichotomy between vertebrates and invertebrates.

Octopamine in invertebrates and vertebrates. A review. JC David, JF Coulon - Prog Neurobiol, 1985 - Prog Neurobiol. 1985;24(2):141-85

TYRAMINE AND OCTOPAMINE: Ruling Behavior and Metabolism T Roeder - Annual Review of Entomology, 2005 - Annual Reviews

The possible role of octopamine as a synaptic transmitter: a review. TP Hicks - Can J Physiol Pharmacol, 1977 -

But whatever the findings, the dichotomy remains due to size differences between terrestrial vertebrates and invertebrates. —Preceding unsigned comment added by (talk) 06:47, 13 March 2010 (UTC)

Create category of cities using biological control?[edit]

It seems to me it would be interesting to create a category to list cities that do regular annual municipal pest control, both biological and chemical. Whitehorse applies biological mosquito control as one of their stated municipal programs on their city website, alongside water and sewage and emergency services. It is well described/presented, so I linked that program to this page. A category for all such cities I think would be very interesting. Thoughts?--Tallard (talk) 10:31, 29 March 2011 (UTC)


as off-shoots from the Conservation section; here are following useful extra article; they can perhaps be added in the see also or external links section:

Natural vs artificial bio pest control[edit]

I added this link:

See also here.

I think we need to mention that simply "doing nothing" in certain areas of the farmland (ie if it's land with trees ((rain)forest) ) can also provide bio pest control. This seems to me to be much more cost-effective than providing bio pest control using some artificial way. KVDP (talk) 07:25, 19 September 2013 (UTC)

I think the 'Conservation' section that's already in the article implicitly covers this, though the info could perhaps be expanded. PaleCloudedWhite (talk) 08:57, 19 September 2013 (UTC)
I disagree; that method still asks for some input of the farmer. I think we need to add a new subsection (1.4 Leaving zones of land as is). I added this info at the see also section which can then be moved there:
  • Permaculture zone 5: leaving an environment as is also sparks the creation of natural predators for areas that are under cultivation

Needs topic split[edit]

Tries to cover too large a topic. Topic wanders focuses mostly on bugs - though i got here searching for weed control. It names weed control then says nothing about it - waste of time looking.

No good or specific advice is given except the obvious: get rid of it somehow, by one of the plainly obvious methods. Did NOT mention the most obvious: manually.


Hiding rant

That's the most jackass thing i've ever heard. and btw importation of species by gov has as often caused DEVISTATION and cost as it has improvement. what a facist.

One name drop product is given but not competetors, also that is wrong to do in article as well.


a government monopoly INTENTIONALLY PLANTED the weeds i'm LEARNING to get rid of - it's well known in my area they did. GOVERNMENT

AFTER i asked the "agent" not to plant anything and he offered an explanation it was not weed.

Bugs, some pests that eat plants

Often local authorities keep track of certain pests and have a plan ready. Though there may be other remedies.

Weeds, De-thatching

Weeds have weak roots and thus pull easier than grass. Thus if dethatched and corrections are made (sun, seeding, soil) the grass should win with thatching.

See heavy duty rake: Rake (tool) and lawn devices about dethatching.

Lawn chemicals work by the same principle, they constrict root systems to a point in which weaker roots do less well. Some chemicals are safe for the environment others not so much, none are safe around small children. If you have a soar throat: stop.

Lawncare experts use both chemicals and de-thatching, and of course farming and planning as said above. (talk) 13:40, 10 September 2014 (UTC)

I formatted your comments into one section to make them easier to reply to. Remember that Wikipedia is not a forum. It's also not a how-to manual, so you'll need to consult professional or university content for help with your weed problem.
Otherwise though, I do agree that the article is unwieldy, but it's needs a major rework before any splitting would even be considered. It does read from the perspective of controlling insects with bio-control, which is very much an undue weight issue since we aren't getting as much on plants or other pest organisms where bio-control is used. Ironically, I'm an entomologist that specializes in biological control, but I would like to take some of the main textbooks on the topic and rework the general content and summarize things better in the future to cover both the pests and biological control agents better and more concisely (probably later this fall). Something for the to-do list, but I'll be keeping an eye on this page. Otherwise, governments actually do tend to be the biggest user of bio-control (at least in classical/importation), and mechanical removing of weeds is not biological control (you need another organism controlling the pest), so those aren't particularly issues here.
