What is a key advantage of using Insect Growth Regulators (IGRs) over traditional broad-spectrum insecticides?
Lower toxicity to non-target organisms
Why do Insect Growth Regulators (IGRs) tend to be more selective in their action compared to traditional insecticides?
They target specific stages of the pest's life cycle
How do Insect Growth Regulators (IGRs) help in delaying the development of resistant pest strains?
Unique mode of action that doesn't induce resistance quickly
What is a potential hazard associated with excessive exposure to certain Insect Growth Regulators (IGRs)?
Reproductive issues and health problems
How does Integrated Pest Management (IPM) contribute to reducing the environmental impact of using Insect Growth Regulators (IGRs)?
By combining multiple strategies to manage pests with fewer chemicals
Why is proper handling, storage, and disposal of Insect Growth Regulators (IGRs) crucial?
To mitigate risks of reproductive issues or health problems
How do Insect Growth Regulators (IGRs) typically disrupt the life cycle of insects?
By interfering with the physiological processes necessary for pest development
What is the specific target of some IGRs when it comes to the developmental stage of larvae?
Preventing larvae from molting to progress through subsequent stages
How do IGRs targeting adults disrupt the insect population?
By preventing eggs or pupae from developing into adult insects
What is a common outcome for larvae affected by IGRs that inhibit the molting process?
Becoming immobile and unable to feed effectively
How do IGRs contribute to reducing the spread of diseases transmitted by insects like mosquitoes?
By preventing mosquitoes from maturing into an infectious stage
What distinguishes Insect Growth Regulators (IGRs) from traditional chemical pesticides in terms of minimizing ecological impact?
They mimic natural hormones and target specific stages of the insect's life cycle
