what is the difference between DDT and Dieldrin?
480929
They are similar in that they are both chlorinated aromatic hydrocarbons.  Think ring carbon structure and then oxidizing it with a powerful oxidizer like chlorine.  Also, hey are both insecticides that are stable or persistent in the environment, hence their bad rep.\n\nDifferences.  Hmmm?  DDT has five chlorines while dieldrin has six.    DDT has two rings (derived from benzene)but they are not fused, while Dieldrin has two fused rings (derived from napthalene).\nI'm sure there is more, such as they mode of reaction, but someone else will have to help.

Insecticides are chemical or biological agents used to control insects either through killing them or decreasing their destructive behaviors.

DDT was the first modern pesticide and is arguably the most well known organic pesticide. It is a highly hydrophobic colorless solid with a weak, chemical odor that is nearly insoluble in water but has a good solubility in most organic solvents, fat, and oils. DDT is also known under the chemical names 1,1,1-trichloro-2,2-bis(p-chlorophenyl)ethane and dichloro-diphenyl-trichloroethane (from which the abbreviation was derived).\n\nDDT was developed as the first of the modern insecticides early in World War II. It was initially used with great effect to combat mosquitoes spreading malaria, typhus, and other insect-borne human diseases among both military and civilian populations, and as an agricultural insecticide. The Swiss chemist Paul Hermann Müller of Geigy Pharmaceutical in Switzerland was awarded the Nobel Prize in Physiology or Medicine in 1948 "for his discovery of the high efficiency of DDT as a contact poison against several arthropods."\n\nIn 1962, American biologist Rachel Carson published the book Silent Spring, which alleged that DDT caused cancer and harmed bird reproduction by thinning egg shells.[1] The book resulted in a large public outcry which eventually led to the insecticide being banned for agricultural use in the USA, and was one of the signature events in the birth of the environmental movement. DDT was subsequently banned for agricultural use in many countries in the 1970s due to what many believe is a negative environmental impact. There is still a great controversy regarding the extent of this impact and the reduced use of DDT to fight human diseases.

Depends on the pesticide.\n\nA broad-leafed herbicide such as Round-Up (glyphosate) or 2,4-D would kill the cabbage.\n\nA bacterial insecticide such as Bacillus thuringiensis kurstaki would have no effect at all on the cabbage.\n\nPesticide is a very broad term, which covers any chemical or product used for the control of pests, including weeds (plants), fungus, invertebrates (including insects) or even vertebrates.  \n\nFor a more specific answer, you'll have to specify which pesticide.

The World Health Organization has approved indoor use of the pesticide DDT. DDT, a chemical that repels and kills insects, will lower the death rate in malaria-affected regions, such as Africa, Asia, and other countries as well. The organization believes that appropriate use of DDT can temporarily control malaria DDT, to this date, remains the only pesticide for this task. However, the opposing side of DDT, the Pesticide Action Network North America, argues that it may cause health problems in children. The side effects include premature birth and development delay. Early forms of DDT also had effects on the environment, including the thinning of bird eggshells and population decline in certain species. The spokesperson of PANNA also insists that malaria can be treated with other less harmful chemicals. One of the less harmful chemicals, pyretheroids, was banned.\n\n\nim not sure about that end part. thats not the end is it??

Some individuals have had success conducting their own exterminations by preparing an insecticide mixture of pyrethrins and fresh-water diatomaceous earth. At least one manufacturer produces a household insecticide D-20 with only .2% naturally derived pyrethrins and 1.0% Piperonyl Butoxide, which magnifies the pyrethrins effectivenes by 10 times. Natural pyrethrins are more expensive than many alternatives. The function of the pyrethrins is to stimulate the nervous system of the bugs so that the spasms will allow the diatomaceous earth to dessicate, puncture, and kill the bugs through mechanical action. Great care should be taken not to use products with salt-water diatomaceous earth or heat-treated diatomaceous earth, which can damage the lungs of any mammal (dogs, cats, or humans) which inhale it, and has also been known to cause cancer. Fresh-water diatomaceous earth, however, is commonly used to deworm cats, dogs, and humans, and is considered as safe as table salt.\n\nOthers have used fruit and vegetable insecticides, comprised of a mixture of pyrethins and canola oil, which are usually safe for humans and most pets (aside from fish).\n\nContrary to popularly disseminated information, extreme heat or extreme cold is usually not effective in eliminating bedbugs. Pest control professionals receive reports of infestations even in the dead of winter, and manufactured environments of extreme heat or cold (such as encasing a mattress in a bag and placing it in direct sunlight, or placing a suspect piece of bedding or clothing in a freezer) usually cannot stay consistently hot or cold enough to sufficiently kill bedbugs, which are not particularly sensitive to temperature extremes. In addition, since bedbugs normally disperse, treatment of a bed or mattress is insufficient to eradicate an infestation.

You should be able to find that information on the epa's mosquito website.  When I tried to access information on Texas, the link was missing but it is http://www.epa.gov/pesticides/health/mosquitoes/resources.htm for future reference.

Naphthalene or paradichlorobenzene?  Either way, yes.
