NEET PG High-Yield: Fly Control
Houseflies (Musca domestica) are mechanical vectors for diseases like typhoid, cholera, and dysentery. Control focuses on interrupting their life cycle.
Control Strategies
| Method | Action/Examples |
|---|---|
| Environmental (Sanitary) | Most effective. Refuse storage, proper disposal, and sanitation. |
| Chemical (Residual) | Spraying walls/ceilings with Malathion or Diazinon. |
| Chemical (Poison Baits) | Sugar/bait mixed with insecticide (e.g., Dichlorvos). |
| Mechanical | Fly traps, sticky papers, and screening of food/windows. |
High-Yield NEET PG Pearls:
- Primary Method: Sanitation (source reduction) is always the first-line and most durable intervention.
- Life Cycle: Understanding the egg-larva-pupa-adult stages is key; control at the larval stage is often more effective than adult control.
- Vector Type: Remember, they are mechanical vectors, not biological (the pathogen does not multiply within the fly).
- Indicator: The presence of excessive houseflies is an indicator of poor sanitation.
