Study Notes
Resistance Management of Pesticides
- Strategies for resistance management have been developed to address the problem of pesticide resistance.
- Two key elements of resistance management: • Reducing the frequency of pesticide use to prevent pests from developing resistance over multiple generations. • Using pesticides at high concentrations to kill individuals with resistance genes, which are likely to be present in heterozygous individuals when resistance is rare.
Complications in Resistance Management
- Non-target species can evolve resistance to pesticides, as they receive reduced doses at the ecological periphery of the treatment zone, allowing heterozygotes to survive.
- Example: In Central America, the malaria vector mosquito Anopheles albimanus showed higher levels of insecticide resistance in cotton-growing areas than in non-cotton-growing areas.
Pesticide Resistance in Insects
- Insects have developed resistance to multiple insecticides due to attempts to change pesticides.
- Prolonged use of pesticides in an area has led to the evolution of insect strains resistant to specific chemicals, such as DDT.
- The resistance problem is exacerbated when pests develop resistance while their natural predators do not, allowing pest populations to increase unchecked.
