Read the following text and answer any four questions on the basis of the same :
Ecological Indicators : The presence of dragonflies can reveal changes in the water ecosystems more quickly than studying other animals or plants. In fact, from the nymph to the adult stage, the dragonfly has a significant, positive ecological impact. Dragonfly eggs are laid and hatched in or near water, so their lives show an impact on both water and land ecosystems. Once hatched, dragonfly nymphs can breathe in the air or underwater which enables them to eat mosquito larvae, other aquatic insects and worms, and even small aquatic vertebrates like tadpoles and small fish. Adult dragonflies capture and eat adult mosquitoes.
Community wide mosquito control programs that spray insecticides to kill adult mosquitoes also kill dragonflies.
Q. The approach to biological control includes :
  • a)
    Import and release of an insect pest to a new area to provide hosts for natural enemies.
  • b)
    Import and release of natural enemies from the native home of an alien insect pest that has invaded a new area.
  • c)
    Preservation of natural enemies (predators & parasites) that are already established in an area.
  • d)
    Use of insecticides to reduce alien insect pests to establish a new equilibrium position.
Correct answer is option 'A'. Can you explain this answer?

Approach to Biological Control:

Biological control is a method of controlling pests using other living organisms. The approach to biological control includes the following strategies:

Import and release of an insect pest to a new area to provide hosts for natural enemies:
- This involves introducing a natural enemy of the pest species to control its population.
- The natural enemy feeds on the pest, reducing its numbers and preventing damage to crops.

Import and release of natural enemies from the native home of an alien insect pest that has invaded a new area:
- In this strategy, natural enemies from the native habitat of the pest are brought into the affected area to control its population.
- These natural enemies are already adapted to the pest species and can effectively reduce its numbers.

Preservation of natural enemies (predators & parasites) that are already established in an area:
- This strategy focuses on protecting and enhancing the populations of natural enemies that are already present in the environment.
- By preserving these predators and parasites, the pest population can be naturally controlled without the need for additional introductions.

Use of insecticides to reduce alien insect pests to establish a new equilibrium position:
- While biological control methods are preferred, in some cases, insecticides may be used to reduce pest populations.
- The goal is to establish a balance between the pest species and its natural enemies, ensuring sustainable pest control in the long term.
