Sample interview questions: How do you assess the impact of insect pests on natural ecosystems and biodiversity?
Sample answer:
Assessing the Impact of Insect Pests on Natural Ecosystems and Biodiversity
To evaluate the impact of insect pests on natural ecosystems and biodiversity, entomologists employ a comprehensive approach that includes:
1. Population Dynamics Monitoring:
- Tracking population densities and distribution of target pests over time using sampling methods (e.g., traps, surveys).
- Analyzing population trends to identify potential outbreaks and assess associated risks.
2. Host Plant Impact Assessment:
- Evaluating the extent of damage caused by pests to host plants, including defoliation, reduced growth, and yield losses.
- Assessing the effects on plant health, reproductive capacity, and overall ecosystem functioning.
3. Competition and Predation Studies:
- Investigating the impact of pests on native insect communities, including competition for resources and predation pressure.
- Determining the potential disruption of natural food webs and ecological balance.
4. Habitat Modification Analysis:
- Assessing the role of habitat modifications (e.g., deforestation, land use changes) in facilitating pest outbreaks.
- Identifying environmental factors that inf… Read full answer
