A pesticide is a chemical designed to kill a pest, whether it is an insect, a weed, or a fungus. Let's use a fictional pest and insecticide we'll call Beetle A and A-B-Gone. At first, A-B-Gone seems to leave no trace of Beetle A. Farmers start using A-B-Gone everywhere. Nearly all of the Beetle A population is wiped out, but there are a few survivors. These survivors have a special mutation that allows them to survive the onslaught of A-B-Gone. The survivors then rapidly multiply, creating a full size population of Beetle A that is totally immune to A-B-Gone. The beetle is now insecticide resistant. Then companies invent a new, more toxic pesticide, and the cycle repeats. The situation is, the insecticides always end up being useless, but they poison the water, soil, and all the organisms in the area in the meantime.
What else can I help you with?
How has crop dusting led to pesticide resistance?
The act of crop dusting itself has not led to pesticide resistance. Mismanagement of pesticide application is the root cause of pesticide resistance.
What is Population Resistance?
Population resistance is also known as pesticide resistance. Pesticide resistance describes a pest population's increasing resistance to a pesticide that use to be effective in terminating said pests.
What is pesticide resistance.?
Pesticide resistance describes the decreased susceptibility of a pest population to a pesticide that was previously effective at controlling the pest.
How does pesticide resistance develop over time?
The pesticide resistance develops over time due to the natural selection.
What are types of pesticide resistance?
Pesticide resistance can be classified into several types, including metabolic resistance, where pests develop enzymes to break down chemicals; target-site resistance, where changes occur in the pest's biological targets of the pesticide; and behavioral resistance, where pests alter their habits to avoid exposure. Additionally, cross-resistance can occur when a pest resistant to one pesticide also shows resistance to related chemicals. These mechanisms can significantly reduce the effectiveness of pest control measures over time.
How are humans contributing to anibiotic and pesticide resistance?
misuse and overuse.
Which describes what happens during the resistance?
f*** it... "s*** happens" el oh el.
What is an example of direct evidence for evolution is... genetic changes in plants antibiotic resistance in bacteria pesticide resistance in insects or all of the above?
All of the above examples are direct evidence for evolution. Genetic changes in plants, antibiotic resistance in bacteria, and pesticide resistance in insects all demonstrate how species can adapt and evolve to survive in changing environments. This supports the theory of evolution by natural selection.
Which concept is represented in a diagram that show the effect of spraying a pesticide on a population of insects over three generation?
The concept being represented in this diagram is likely the idea of pesticide resistance. The diagram is showing how the population of insects evolves resistance to the pesticide over generations, leading to a decrease in its effectiveness.
How pesticides resistance evolve?
Pesticide resistance evolves through natural selection. When a pesticide is applied, some individuals within the target pest population may have genetic variations that make them less susceptible to the pesticide's effects. These individuals survive, reproduce, and pass on their resistant traits to their offspring, leading to an increase in resistance over time. Continuous use of the same pesticide can further select for resistance, making it more difficult to control the pest population.
When a pesticide is sprayed and there are still survivorswhat can you assume about them?
When there are survivors after a pesticide is sprayed, it can be assumed that these individuals possess some level of resistance or tolerance to the active ingredient in the pesticide. This resistance may arise from genetic variations that allow them to survive exposure. Additionally, the survivors could have been in microhabitats where the pesticide concentration was lower or they may have behaviors that enabled them to evade the spray. Over time, these resistant individuals can contribute to a population that may become increasingly difficult to control with the same pesticide.
What are the positives of genetically modified food?
-more food production - better nutrition - pesticide resistance
