What two factors may contribute to insecticide resistance?
Large populations and previous exposure to environmental residue are two factors which may contribute to insecticide resistance. Strengthened immune systems can result from interactions with previous applications of the insecticide and from mutants within large numbers of same-generation, same-litter insects.
Why would insect population rebound after the use of DDT?
the insects might have developed a resistance to the insecticide
What has the author Peter W Shearer written?
Peter W. Shearer has written: 'Monitoring insecticide resistance of the western tentiform leafminer Phyllonorycter elmaella (Doganlar and Mutuura) (Lepidoptera: Gracillariidae) in northern Oregon' -- subject(s): Insecticide resistance, Leaf-miners
Why is killing bees using insecticide causing a problem?
in the bee stinger that will attract other bees and causes problem.
How do insecticides force evolution?
Widespread use of insecticides can lead to the evolution of insecticide resistance. In any population of insects there will be genetic variation ie individual insects are not identical; just like humans there are all different. Some individual insects will be more resistant to an insecticide than others. When an insecticide is used the individuals which are resistant will have a better chance of surviving. They will then pass on their resistance genes to their offspring, which will in turn have a better chance of surviving. In this way the resistance genes will spread through the population. This is an example of natural selection in action. See www.evolution.berkeley.edu/
Why do insecticide resistant organisms develop?
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.
Is global a proper noun?
Its an adjective As in "It is a global problem"
What are the benefits of using a non-repellent insecticide for pest control?
Using a non-repellent insecticide for pest control has benefits such as effectively killing pests without them detecting the chemical, leading to better control of infestations and reducing the chances of resistance developing in the pests.
What is the prefix of insecticide?
the prefix of the word insecticide is -in
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.
How do you kill a cicada?
use the systemic insecticide or the common spray insecticide. but better you use the systemic insecticide.
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
