- Pest Management
- Biological control agents
- Biological control agents involve bringing in the natural predator of the pest
- The aim of this is to control the pest, not eradicate it
- Advantages
- Are very specific
- They do not need to be reapplied because the organism will reproduce
- Pests cannot become resistant to BCAs
- Disadvantages
- The BCA may end up becoming a pest, as with the cane toad
- These usually take a while to 'kick in'
- Chemical pesticides
- Pesticides are chemicals that are designed to kill pests
- Good pesticides should:
- Be specific and only target the pest they were designed for
- Not bioaccumulate to reduce the chance of them entering the food chain
- Be cost-effective
- Break down into harmless chemicals
- Advantages
- They usually take effect very quickly
- Are usually very effective at killing pests
- Disadvantages
- The chemicals almost always have some effect on non-target organisms
- They must be reapplied at intervals
- Pests can develop a genetic resistance to the chemicals
- Integrated pest management
- 1. Choosing animal and plant species that suit the local area
- 2. Providing a suitable habitat for natural predators
- 3. Regular screening for signs of pests
- 4. Removing the pest manually (by hand picking)
- 5. BCAs
- 6. Pesticides as a last resort
- Biological control agents
