    • E.

      5,000

    Correct Answer
    C. 1,000
    Explanation
    Since 1945, around 1,000 species of insects have developed resistance to one or more insecticides. This means that these insects have evolved mechanisms to survive exposure to insecticides that would normally kill them. This resistance can occur through various mechanisms such as genetic mutations or changes in behavior. The development of resistance in insects is a significant concern as it poses challenges for pest control and can lead to reduced effectiveness of insecticides over time.

    Rate this question:

  • 4. 

    Broad-spectrum pesticides may increase the number of best species through

    • A.

      Development of genetic resistance

    • B.

      Killing of predators of the pest species

    • C.

      Killing of parasites that may have kept the population of the pest low

    • D.

      Both killing of predators of the pest species and killing of parasites that may have kept the population of the pest low

    • E.

      All of these answers are correct

    Correct Answer
    E. All of these answers are correct
    Explanation
    Broad-spectrum pesticides can increase the number of pest species by multiple mechanisms. Firstly, they can lead to the development of genetic resistance in the pests, making them less susceptible to the pesticide over time. Additionally, these pesticides can kill the predators of the pest species, which would have otherwise helped control their population. Furthermore, they can also eliminate parasites that naturally keep the pest population low. Therefore, all of the given answers are correct in explaining how broad-spectrum pesticides may increase the number of pest species.

    Rate this question:

  • 5. 

    Which of the following approaches would be the least beneficial in trying to reduce insect damage

    • A.

      Rotating crops

    • B.

      Genetic engineering of crops

    • C.

      Planting monocultures

    • D.

      Bringing in natural enemies

    • E.

      Planting polycultures

    Correct Answer
    C. Planting monocultures
    Explanation
    Planting monocultures would be the least beneficial approach in trying to reduce insect damage. Monocultures refer to the practice of growing only one type of crop in a large area. This lack of diversity makes the crops more vulnerable to insect pests, as the pests can easily spread and multiply in such a concentrated environment. In contrast, rotating crops, genetic engineering of crops, bringing in natural enemies, and planting polycultures all promote biodiversity and can help reduce insect damage by disrupting pest lifecycles and providing natural pest control mechanisms.

    Rate this question:

  • 6. 

    Biological control of pests

    • A.

      Costs more money than pesticides to use

    • B.

      Is toxic to use

    • C.

      Is fast-acting

    • D.

      Is not toxic to use

    • E.

      Has never been very effective

    Correct Answer
    D. Is not toxic to use
    Explanation
    Biological control of pests is a method that involves using natural predators, parasites, or pathogens to control pest populations. Unlike pesticides, which can be toxic to both pests and the environment, biological control is not toxic to use. This method relies on the introduction or enhancement of natural enemies to regulate pest populations, providing a more eco-friendly and sustainable approach to pest management. While it may require additional costs and may not always be as fast-acting as pesticides, the fact that it is not toxic to use makes it a preferred option for many.

    • C.

      Insects develop resistance to pheromones

    • D.

      They are biologically magnified in nontarget species

    • E.

      They only work in large amounts

    Correct Answer
    A. They are costly and time-consuming to produce
    Explanation
    The weakness of using pheromones is that they are costly and time-consuming to produce. This means that it requires a significant investment of resources and time to produce enough pheromones for effective use. This can be a limitation in terms of scalability and practicality, especially in large-scale applications or when dealing with limited resources.

      A strong new form of chemical insecticide awaiting approval by FIFRA

    • B.

      A strong herbicide

    • C.

      A species-specific chemical sex attractant

    • D.

      A chemical that controls an organisms's growth and development

    • E.

      A strong pesticide

    Correct Answer
    D. A chemical that controls an organisms's growth and development
    Explanation
    The correct answer is "A chemical that controls an organism's growth and development." This is because hormones are chemical substances produced by the body that regulate various physiological processes, including growth and development. They act as messengers, signaling cells or tissues to perform specific functions and maintain homeostasis within the organism. Hormones play a crucial role in controlling processes such as metabolism, reproduction, and response to stress.
