Talk:Insecticide

1. Insecticides

It is chemically more correct to talk about organochlorine insecitides / compounds, for the chlorinated hydrocarbons we are dealing with are not chlorides. I propose to change this through the entire article. (RapidoII (talk) 10:05, 9 September 2008 (UTC))

There is significant disagreement over the actual environmental effects of DDT use in human habitation. Blind obeisance to agenda-driven screeds such as Rachel Carson's 'Silent Spring' which resulted in worldwide bans on its use is directly responsible for millions of deaths from malaria in underdeveloped countries.

This controversy should be explored in an unbiased manner.50.10.99.70 (talk) 05:43, 21 May 2011 (UTC)

There is no disagreement on the environmental effects of DDT and its breakdown products like DDE. These compounds are toxic, persistent and bioaccumulative and there is an enormous scientific paper corpus documenting modes of action and effects. 2001:BB6:1852:A700:7406:AAFB:777B:2220 (talk) 09:31, 11 July 2022 (UTC)

Classes of agricultural insecticides

Mode of action should be removed from the entry "The classification is done in several different ways", while the entire entry would benefit from a more logical organisation / formatting. How would we classify insecticides which are fermentation products like Dow AgroSciences' spinosad? Organic Insecticides? (RapidoII (talk) 10:09, 9 September 2008 (UTC)) I beg to differ - MoA is by far the most satisfactory way to classify all pesticides. Spinosad is in group 5. Roy Bateman (talk) 07:26, 13 December 2016 (UTC)

Focus on environmental effects

"Scare quotes" and strawmen do not an argument make. Sections like this make the entire encyclopedia look amateurish.

The article does not represent insecticides in an encyclopedic fashion. The article's main section is Environmental effects, with no mention of history, developement or worldwide usage. There are most definately well documented adverse effects of insecticides and these should be included. However, the article is not a forum to discuss only why restricting DTT use to vector control has reduced selection of resistant insects. The article should be a broad and NPOV review of insecticides in general. Goldfinger820 05:51, 23 December 2005 (UTC)

Agreed. It needs a re-write. Bihal 22:54, 23 January 2006 (UTC)

Totally agreed. This article also contains a great degree of negative, non-neutral phrases, e.g. opponents to environmentalism; this accusation, while sensational... More objective phrases should be used.

Doesn't really explain how insecticides work, except to say that they work on the nervous system.

kramsay 24 May 2006

I did not realize that DDT caused euphoria...where can I get some? The article is reasonably well done considering one of the biggest concerns regarding insecticides is environmental but there is insufficient information on the mechanistic function of insecticides to make the extensiveness of the environmental discussion reasonable.

There is no solid scientific evidence that DDT causes the thinning of egg shells. This article reeks of POV. HvySlpr (talk) 23:47, 29 July 2008 (UTC)HvySlpr

This is simply not true. There are many experiments showing mode of action e.g. Lundholm, E. 1987, "Thinning of eggshells in birds by DDE: Mode of action on the eggshell gland", Comparative Biochemistry and Physiology, C, vol. 88C, no. 1, pp. 1-22. 2001:BB6:1852:A700:7406:AAFB:777B:2220 (talk) 09:29, 11 July 2022 (UTC)

Merge

Can someone who edits this article please merge articles like ovicide and larvicide either here or into Types of insecticide if need be? Richard001 04:03, 15 July 2007 (UTC)

Went ahead with ovicide, but larvicide is a pretty respectable stub, so I left it alone. Someone else can do it if they want though. Removing merge tag. delldot talk 20:32, 3 October 2007

Ovicide

Actually, this could also refer to the killing of eggs by animals, a form of infanticide. Perhaps a disambiguation would be better for this? Richard001 (talk) 21:23, 23 March 2008 (UTC)

A standardized definition of the term of insecticide is needed...

If it belong to the category of pesticides, then the products may have to be regulated--222.64.27.1 (talk) 23:26, 1 June 2009 (UTC)

Perhaps there is a USDA or other legal definition, but there are other countries where such "regulations" can differ but the article certainly needs an overhaul with citations. Shyamal (talk) 09:26, 2 June 2009 (UTC)

Section on "environmental impacts" but almost no material on impacts on human health

I will get on this soon, probably create a new section, I just wanted to bring it to people's attention that I think this is a serious omission on this article, as this has been extensively studied in the scientific literature, and there is already material on specific pages for various insecticides. Cazort (talk) 15:40, 25 June 2009 (UTC)

General POV issues

A lot of this article reads as prescriptive, normative statements--i.e. insecticides should be used in this way, they should not be used in this way, etc. and these comments are totally unsourced. I find this very problematic. I think we need to source such statements and state "Such-and-such group recommends to use insecticides in such a way." or "such-and-such group warns against X on the grounds of Y". I think if there is a clear scientific consensus of any of the statements, this needs to be backed up with multiple sources and identified as a consensus. The article now is just full of bold, unfounded assertions. Cazort (talk) 15:55, 25 June 2009 (UTC)

Agree with the above. There is also a danger that issues are raised that belong on other pages - so for instance, I have moved application of household insecticides to the pesticide application page. Roy Bateman (talk) 10:01, 15 August 2009 (UTC) examples of insecticides substance are:baygon mighty killer,kwik and other chemichal substances.

Merging "Natural insecticides" with "Insecticides" articles

The "Natural insecticides" article contains conclusions derived directly from 2010 Research and development of a specific company (Provipax S.A.). As data put forward in the specific article have been recently discovered we feel that it should stand alone and NOT be merged with any other article, having a lot to offer to the reader after it's editing has finished. Thank you. — Preceding unsigned comment added by Dandreadis (talk • contribs) 23:25, 22 December 2010

The Natural insecticides article has been deleted so this discussion is now moot. Malcolmxl5 (talk) 17:00, 20 January 2011 (UTC)

Alternatives

I am adding an alternatives section to this article to talk about Integrated Pest Management. Feel free to leave a comment here or on my talk page if you think anything I write is inappropriate for Wikipedia. Anuprecious (talk) 04:15, 12 December 2018 (UTC)

IP editor: these Talk Pages are places to discuss improvements to articles, in this case insecticide. Do you have a suggested improvement? Mike Turnbull (talk) 15:37, 26 September 2023 (UTC)

Systemic Insecticides

Systemic insecticides are taken up by the plant and than migrate within the plant. They can thus kill insects eating (or sucking from) the plant at a place different to the place where the insecticide was applied. I just corrected the statement that systemicity means long-lasting or residual activity. There is a remnant of this misunderstanding in the "contact insecticide" section saying that contact insecticides are not long lasting. This statement should probably be deleted. Another problem is the statement that the Bt in Bt GMOs is systemic. The statement that it is incorporated thoughout the plant is correct, but I don't think that makes it a systemic insecticide. I am not complete certain that the term "systemic insecticide" is never used for Bt in Bt-GMOs, but it is not used in the citation given. If no-one has any objections I will modify the text correspondingly.Bosula (talk) 18:14, 8 November 2023 (UTC)

All your suggestions sound like improvements to me, so go ahead. Pyrethroids are, of course the classic example of long-lasting contact insecticides, so a reference for one of those (e.g. cyhalothrin) could be used when clarifying that part. Mike Turnbull (talk) 18:20, 8 November 2023 (UTC)

Hello Mike,

I deleted the bit about contact insecticides not showing residual activity, citing cyhalothrin. I wrote on the Bt talk page asking if anyone knew if Bt-toxin moved in plants or not. I assume not but hesitate to modify the text without knowing.

The section on Insecticide Development links to Pesticide Development, which badly needs improvement and which I will improve. Can I ask your opinion on the statement there starting with "Insecticide development is being discouraged and slowed down by public sentiment surrounding the worldwide colony collapse disorder crisis." This is not true, and I won't be able to find literature citing the continued research budgets. Can you think of any legitimate way of deleting this paragraph?

Also can I ask you another question. Have you met any disadvantages of using your name? I followed what I thought was the recommended procedure and used an old userid. However if there are no disadvantaged I will put my name in the user page.

regards, Tony Bosula (talk) 13:21, 9 November 2023 (UTC)

On the CCD mention, that looks like WP:OR to claim development was slowed due to CCD. One could make the case for general pollinator concerns rather than just CCD since the links to pesticides are more nebulous and complicated, but sources would still be needed over at that article.

As for names, I be careful and suggest not using them in this topic unless WP:DOXXING is not a concern for you. That's not about content though, so happy to discuss some of that on my user talk page. KoA (talk) 16:33, 9 November 2023 (UTC)

I will make another comment on the Pesticide page in the "discovery" section, about the lack of information on the criteria used by agencies funding academic research. I will keep using my code name in the meantime (thanks for the tip). Bosula (talk) 12:41, 16 November 2023 (UTC)
