Evolution. Each generation has some differences from the preceding generations. The survivors from one generation pass their genes on to subsequent generations. A trait that increases survival rate (resistance to an insectide) is passed on more frequently than a trait which is detrimental to procreation.
What else can I help you with?
A large population of the house flies was sprayed with a newly developed fast-acting insecticide the appearance of some house flies that are resistant to this insecticide supports the concept that?
there is genetic variation within the house fly population. The resistant house flies were able to survive the insecticide because they carried genes that made them immune to its effects. Over time, if these resistant house flies survive and reproduce, the overall population may become more resistant to the insecticide.
Humans have inadvertently promoted the evolution of insects that are resistant to insecticides by?
Insects became resistant because the insecticides were used on the continuously. Most insects will die at first, but there will be some that have the right genetics to resist that insecticide. When that happens the insect will the favorable gene reproduces and creates more insects that are resistant. Humans promoted this evolution by using the same insecticide on the insects.
What do all organisms have?
All organisms have cells, grow and develop, reproduce, maintain homeostasis, and respond to their environment.
Within a decade of the introduction of a new insecticide nearly all of the descendants of the target pests were immune to the usual-sized dose the most likely explanation for this immunity is that?
Natural selection is one way to explain it. When the survivals of the insecticide reproduced, the gene that allowed them to live was passed on. In time, the gene was spread throughout the entire population and every member of the pest became immune.
What will scientists have to develop to kill these new resistant strains?
Scientists will need to develop alternative treatments to target the specific mechanisms of resistance in these new strains. This could involve creating new antibiotics or combination therapies that can effectively combat the resistant bacteria. Additionally, strategies to prevent the spread of resistance, such as improved infection control measures, will also be crucial.
What are insecticide resistant organisms?
Many insects can develop a resistance, typically those that are commonly treated and breed quickly, like bedbugs, roaches, even rodents

Why does insecticide that used to work will no longer affect an insect population?
Because there are always individual insects that are stronger than the rest, and they survive to breed. Their offspring will also be strong, or resistant to the insecticide. In time all that's left is a resistant population!
How is fluorine used in insecticides?
Fluorine is used in some insecticides to increase their effectiveness by enhancing their potency and reducing their toxicity to non-target organisms. It can help to improve the stability and durability of the insecticide, making it more resistant to environmental degradation.
What three organisms that might be killed if the farmer sprayed insecticide on them?
Bees, ladybugs, and earthworms might be killed if the farmer sprayed insecticide on them. Each of these organisms have important roles in the ecosystem, such as pollination, pest control, and soil health.
What is insecticide poisoning?
Insecticide poisoning is exposure to a group of chemicals designed to eradicate insects that cause affected persons to develop clinical signs that can progress to death.
What does resistant or susceptible mean?
These terms refer to antibiotic sensitivities; antibiotic resistant organisms versus antibiotic susceptible organisms.
Within a decade of the introduction of a new insecticide nearly all of the descendants of the target pests were immune to the usual sized dose the most likely explanation for this immunity to the in?
eating the insecticide caused bugs to become resistant to it.
What do you call on the organisms that a insect killer?
The organisms which eat insects are called insectivores.
What is true of organisms?
Organisms grow and develop

Why does an insecticide that used to work well no longer affect an insects population?
An insecticide that used to work well may no longer affect an insect population if they grow resistant to it. This occurs when some individuals are able to survive, and then pass on their genes to the next generations.
