Read the first 6 Vector Control and Pest Management flashcards as text

  1. In public health, what is a 'vector' in the context of disease transmission?

    Answer: An organism that transmits a pathogen from one host to another

    A vector is a living organism, typically an arthropod such as a mosquito or tick, that transmits a pathogen between infected and uninfected hosts.

  2. Which mosquito genus is the primary vector for West Nile virus in the United States?

    Answer: Culex

    Culex mosquitoes, particularly Culex pipiens and Culex quinquefasciatus, are the primary vectors responsible for transmitting West Nile virus in the United States.

  3. What Integrated Pest Management (IPM) principle should be applied first before considering pesticide application?

    Answer: Identify the pest and use non-chemical prevention and control methods first

    IPM principles prioritize accurate pest identification followed by non-chemical strategies such as sanitation, exclusion, and habitat modification before resorting to pesticide application.

  4. Which disease is transmitted by Ixodes scapularis (black-legged tick) in the northeastern United States?

    Answer: Lyme disease

    Ixodes scapularis, commonly called the deer tick or black-legged tick, is the primary vector of Lyme disease caused by the bacterium Borrelia burgdorferi in the northeastern US.

  5. What is the primary purpose of source reduction in mosquito control programs?

    Answer: To eliminate or modify breeding habitats to prevent mosquito larval development

    Source reduction targets mosquito breeding sites by eliminating standing water, draining containers, or modifying drainage to prevent larval development before adult mosquitoes emerge.

  6. What is 'resistance management' in the context of pesticide use for vector control?

    Answer: Rotating pesticide classes and using non-chemical methods to prevent development of pesticide-resistant pest populations

    Resistance management involves rotating pesticide classes with different modes of action and integrating non-chemical control methods to slow the development of genetically resistant pest populations.
