Questions Related to zoology

The practices like hand-picking, barriers, traps, vacuuming and tillage to disrupt breeding is considered under

zoology sustainable agriculture microbes and farming biopesticide environmental protection

  1. Mechanical control

  2. Biological control

  3. Responsible use

  4. None of the above

Show answer
Correct Option: A
Explanation:

Integrated pests management is a method which uses the natural agents like the microbes and insects to control the population of other harmful pests and insects. Mechanical control is applied when the pests reach an unacceptable level. This method includes techniques like bagging fruit, sieves, hand-picking, barriers, traps, vacuuming and tillage to disrupt breeding. 

Thus, the correct answer is option A.

How many basic set of principles are included in integrated pests management?

  1. Five

  2. Four

  3. Twenty

  4. Eight

Show answer
Correct Option: D
Explanation:

Eight basic principles are included in integrated pest management.

  • Achieving prevention and suppression of harmful organisms.
  • Monitoring of harmful organisms.
  • Decisions made based on monitoring and thresholds.
  • Non-chemical methods.
  • Pesticide Selection.
  • Reduced Use of Pesticides.
  • Anti-resistance strategies.
  • Evaluation.
So, the correct answer is option D.

Plant and animal quarantines are included in

  1. Regulatory methods

  2. Chemical methods

  3. Cultural methods

  4. Monitoring method

Show answer
Correct Option: A
Explanation:

Integrated pests management is a method which uses the natural agents like the microbes and insects to control the population of other harmful pests and insects. Different methods are used for the control of the pests. When the plant and the animals are affected by the pests or disease, they are shifted to a place and quarantined to prevent the other plants and animals from getting affected. These are considered under the regulatory methods. 

Thus, the correct answer is option A.

  1. Biological method

  2. Mechanical method

  3. Regulatory methods

  4. Chemical methods

Show answer
Correct Option: B
Explanation:

Integrated pests management is a method which uses the natural agents like the microbes and insects to control the population of other harmful pests and insects. Mechanical control is applied when the pests reach an unacceptable level. This method includes techniques like screens, beating with stick, bagging fruit, sieves, hand-picking, barriers, traps, vacuuming and tillage to disrupt breeding. 

Thus, the correct answer is option B.

The phenomenon of using a predator for controlling a pest is

  1. Biological control

  2. Genetic engineering

  3. Artificial control

  4. Confusion technique

Show answer
Correct Option: A
Explanation:

Biological control is a method to control pest by using living microorganisms or its product. It is used as natural enemies like the predators, parasites, pathogens, and competitors to suppress and maintain populations of a target pest species (insects, mites, weeds, plant pathogens, and other pest organisms). This is the most widely used method in today's world for the control of pests. 

Thus, the correct answer is option A.
