Principles of Arthropod Control
Arthropod control is a vital component of public health aimed at preventing vector-borne diseases (e.g., Malaria, Dengue, Zika, Filariasis). Modern approaches prioritize Integrated Vector Management (IVM).
Methods of Control
| Method | Action |
|---|---|
| Environmental | Source reduction, drainage, and modifying habitats (e.g., filling stagnant water). |
| Chemical | Insecticides (organophosphates, pyrethroids), larvicides, repellents. |
| Biological | Using natural predators (e.g., Gambusia fish for mosquito larvae). |
| Genetic | Sterile insect technique (SIT), genetically modified mosquitoes. |
High-Yield Public Health Notes:
- Source Reduction: The most permanent and effective method (e.g., destroying breeding sites).
- Residual Spraying: Indoor Residual Spraying (IRS) remains a cornerstone for malaria control, focusing on resting surfaces.
- Insecticide Resistance: A major challenge; requires rotation of chemical classes and monitoring of vector susceptibility.
- Personal Protection: Use of LLINs (Long-Lasting Insecticidal Nets) and repellents (DEET).
