This is very much just a starter. I finally found a general definition (and since EPPO standards are accepted in EU legislation this should be acceptable)
Suggested sections are (in no particular order).
I have knowledge/expertise in insecticide and fungicide resistance and would be grateful for inputs in other areas, particularly herbicides.
It may make sense to split off articles on insecticide/herbicide/fungicide resistance.
All comments welcome. Maccheek 09:40, 7 November 2006 (UTC)
I'm glad people have made an attempt at expanding this article but I think there are a number of areas that need to be addressed. The referencing is also poor, Introduction to insect biology and diversity, is not an appropriate source for information on resistance.
Parts of the article are taking an anti pesticide stance, while some of the comments may be valid they ignore the benefits of pesticides and that new compounds are much safer.
also, the sentence about Rachel Carson predicting the resistance does not seem to be that relevant, and lacks an adequate source. — Preceding unsigned comment added by 173.202.194.9 ( talk) 03:18, 24 November 2011 (UTC)
Biased towards insecticides and based on general sources that appear to have little specialist knowledge of the area. The first sentence is debatable on not particularly relevant. The second paragraph is unlikely to be true in much of the developed world. Second sentence of third paragraph is of very minor relevance. First sentence of fourth has misinterpreted the facts, or at least is badly written in such a way that it can be misinterpreted.
The first known case of pesticide resistance was not to DDT but was I believe in San Jose scale to lime sulphur in 1908. The examples ought to focus on particularly important cases, Colorado Potato beetles (resistant to 16 insecticide groups up to 1984), Diamond Back Moth, Tobacco Whitefly, Black Sigatoka disease.
The physiology focuses on only one mechanisms of resistance, and does so poorly. A pest does not "develop an enzyme", it may produce more of an enzyme or it may mutate an existing one but it won't produce a new one. Resistance may be caused by; Up rating detoxification mechanisms Increasing transport of the chemical away from the active site Insensitivity of the active site Sequestration Decreased penetration Changes in behaviour
I will when I find time, mainly to track down more appropriate references as I don't have easy access to an academic library! And amongst other things I have a meeting on fungicide resistance to arrange!

Artificial selection refers to when humans deliberately select for particular traits by deciding which members of a population to breed. This is not really what is going on with pesticide resistance (I hope...) so I have changed this to "selection", which describes both artificial and natural selection.

The introduction to this page says that Rachel Carson predicted pesticide resistance in 1962. However, the DDT article notes that DDT resistance was *observed* in 1956. Any suggestions? -- De Guerre ( talk) 02:22, 6 June 2014 (UTC)

Hello @ Waddie96: This short description [1] is over 40 characters long and that is the recommended limit. I wrote the previous version however I'm not sure it's very good and we don't have to keep it. However I think we should stay at/under 40. Invasive Spices ( talk) 22:28, 7 November 2021 (UTC)
