When an insect eats plant matter that has been treated with DDT in which part of the insect would you expect the DDT to collect?
When an insect consumes plant matter treated with DDT, the chemical is likely to accumulate in its fat tissues. DDT is a lipophilic compound, meaning it tends to dissolve in fats rather than water, leading to bioaccumulation in the fat reserves of the insect. Over time, this accumulation can have toxic effects on the insect and can also impact predators that consume the insect.
Can DDT cause malaria?
No, DDT does not cause malaria. DDT is actually used to control the mosquito populations that spread malaria by killing the mosquitoes that carry the disease. Using DDT in a controlled and targeted manner can help reduce the incidence of malaria.
What was the first man-made insecticide?
The first man-made insecticide was DDT, which was developed in 1939 by a Swiss chemist named Paul Hermann Müller. DDT was widely used to control insect pests during World War II and in agriculture until its harmful effects on the environment and human health were discovered.
What were DDT uses?
DDT was used in the later 1950's and early 1960's for the erradication of mosquitoes, and other insects. It pretty much cured the Malaria in America and a great deal of the world. It was banned and now once again we are having a problem with Malaria and other insect borne infections.
What did the study in a Pennsylvania forest reveal about the environmental effects of using DDT?
The study in a Pennsylvania forest found that using DDT led to declines in bird populations due to eggshell thinning, which made them more susceptible to breaking during incubation. This ultimately disrupted the ecosystem by harming bird reproduction and population dynamics.
How does the narrator in the top of the food chain first try to control the insect population of Borneo?
He sprays DDT.
Why would insect population rebound after the use of DDT?
the insects might have developed a resistance to the insecticide
How does the narrator in Top of the Food Chain first try to control the insect population of Borneo?
He sprays DDT.

The use of DDT to control insect pests is?
Banned in most countries now
How has the eagle population fared since DDT use was banned?
Since DDT was banned, the population of bald eagles has increased, and the species has been moved from the endangered list to the threatened list. The population increased by about 15% during the first ten years after DDT was banned.
What effects can a DDT ban have on the population of fish?
DDT is dangerous for all living beings; but also is a very good insecticide.
What did the study in Pennsylvania forest reveal about the environmental effects of using DDT?
DDT killed ladybugs, which caused the aphid population to rise.
Can DDT cause malaria?
No, DDT does not cause malaria. DDT is actually used to control the mosquito populations that spread malaria by killing the mosquitoes that carry the disease. Using DDT in a controlled and targeted manner can help reduce the incidence of malaria.
How did the bald eagle die out?
DDT caused eggshells to be too brittle to hatch, and the eagles numbers plummeted..With the banning of DDT the population has rebounded to a point where they are no longer endangered.
What is the relationship between biological magnification and the reduction of the bald eagle population by pesticide DDT?
because DDT accumulates in fatty tissue, DDT concentrations increase as this chemical moves up in the food chain because at the top of the food chain, DDT concentration has increased almost 10 million times
