Study Notes
- Biological control refers to the use of living organisms to manage pests, pathogens, and weeds
- Biological control offers advantages in agriculture and ecosystem management
- Biological control involves managing invertebrate pests, weeds, and plant pathogens
History
- 1762: Birds were used to control locusts
- 1888: The cottony cushion scale was controlled in citrus
- 1929: A beetle was used against cottony cushion scale
- 1964: A parasite was used to control castor semilooper
Factors Governing Biological Control
- Crop Factors: Tolerance to injury, crop value, and duration influence the effectiveness of biological control
- Pest Origin: Whether a pest is indigenous or exotic influences control strategies
- Environmental Conditions: Seasons and pesticide use can impact the effectiveness biological control
Characteristics of Effective Natural Enemies:
- Adaptability for thriving in different environments
- Host Specificity in targeting specific pests
- Rapid Multiplication to establish populations quickly
- High Search Capacity to effectively locate pests
- Easy Laboratory Culture for research and mass production
Challenges in Biological Control
- Hyperparasites can reduce the effectiveness of primary parasites
- Pesticide Use may harm natural enemies alongside pests
- Environmental Variability can affect reproduction and survival of biocontrol agents
Future
- Genetic Enhancement of natural enemies and improved mass rearing techniques are areas of research
- Integration involves combining biocontrol with other sustainable pest management strategies
