Question
1.Select and describe one example of antibiotic resistance or pesticide resistance. Be specific in your choice.?Describe the background for your choice of resistance. Include details about the disease or pest and the established control strategies. How have we used antibiotics (to treat a particular disease), or pesticides (to protect from a pest); and how has this changed?
2.Explain how the resistant trait evolved based on principles of natural selection and evolution of a trait at the population level.
3.For your specific example, what are the consequences of resistance in terms of human health or crop loss / damage?
4.What steps can be taken to prevent or slow down the evolution of antibiotic or pesticide resistance? Do you think we will succeed in doing so? Why or why not?
Provide references in APA format. This includes a reference list and in-text citations for references used throughout the assignment.
Explanation / Answer
3.For your specific example, what are the consequences of resistance in terms of human health or crop loss / damage? Pests survive and kill our crops. Human loss and damage - less food means fewer mouths are fed, a particular problem for third-world countries that still don't have enough food. Pesticide resistance will also mean that our food might be contaminated with these pests AND the pesticides used to treat them - a double problem that studies are beginning to indicate might contribute to higher rates or earlier onsets of cancer. 4.What steps can be taken to prevent or slow down the evolution of antibiotic or pesticide resistance? Do you think we will succeed in doing so? Why or why not? Pest resistance to a pesticide can be managed by reducing selection pressure by this pesticide on the pest population. In other words, the situation when all the pests except the most resistant ones are killed by a given chemical should be avoided. This can be achieved by avoiding unnecessary pesticide applications, using non-chemical control techniques, and leaving untreated refuges where susceptible pests can survive. 4. Will this succeed? According to evolutionary principles, no - not in the long run. Pesticide resistance will never "end" because it can never be "wiped" from the gene pool until all pests are eliminated - which will never happen.
