All flashcards
Flashcard 1: Identify one example of a chemical control method.
Answer: Application of insecticides. Direct chemical application for immediate pest mortality.
Flashcard 2: What does pest tolerance in crops refer to?
Answer: The ability of a crop to withstand pest damage. Plants continue functioning despite pest presence and damage.
Flashcard 3: Which method involves using plant-derived oils for pest control?
Answer: Botanical control. Plant compounds provide natural pest deterrent properties.
Flashcard 4: Which approach involves habitat manipulation for pest control?
Answer: Ecological control. Environmental modifications enhance natural pest control processes.
Flashcard 5: Which IPM step involves monitoring pest populations?
Answer: Pest identification and monitoring. Essential first step to determine when intervention is needed.
Flashcard 6: Which control method relies on genetic resistance?
Answer: Cultural control. Plant breeding develops varieties with inherent pest resistance.
Flashcard 7: What is the main disadvantage of chemical pest control?
Answer: Potential development of pest resistance. Repeated exposure leads to evolution of resistant pest populations.
Flashcard 8: Name a disadvantage of biological pest control.
Answer: It may take longer to reduce pest populations. Natural control agents require time to establish effective populations.
Flashcard 9: State one risk of overusing chemical pesticides.
Answer: Development of pesticide-resistant pest strains. Evolutionary pressure selects for resistance in pest populations.
Flashcard 10: Identify a practice that increases biological control effectiveness.
Answer: Conserving natural enemy habitats. Maintaining beneficial insect populations enhances natural pest suppression.
Flashcard 11: Which control method uses reflective mulches?
Answer: Physical control. Light reflection disrupts pest navigation and host finding.
Flashcard 12: What is 'biopesticide'?
Answer: A type of pesticide derived from natural materials. Naturally-derived compounds often safer than synthetic chemicals.
Flashcard 13: Which practice involves altering planting times to avoid pests?
Answer: Cultural control. Timing adjustments disrupt pest reproductive cycles and development.
Flashcard 14: Identify a pest control strategy that involves habitat diversification.
Answer: Ecological control. Multiple habitats support various natural enemies of pests.
Flashcard 15: Which method involves adjusting irrigation to manage pests?
Answer: Cultural control. Water management affects pest habitat conditions and survival.
Flashcard 16: What is the role of quarantine in pest management?
Answer: To prevent the importation of foreign pests. Inspection and isolation prevent establishment of invasive species.
Flashcard 17: Identify a challenge in biological control.
Answer: Establishing a balance without harming non-target species. Requires careful species selection to avoid ecological disruption.
Flashcard 18: Identify a practice that supports integrated pest management.
Answer: Regular monitoring of pest populations. Data collection informs timing and necessity of interventions.
Flashcard 19: What is a pheromone trap used for in pest control?
Answer: To attract and capture pests using chemical signals. Species-specific chemicals lure pests for monitoring or control.
Flashcard 20: Identify a key benefit of IPM.
Answer: Reduces reliance on chemical pesticides. Minimizes environmental impact while maintaining crop protection.
Flashcard 21: Identify a mechanical control method for pests.
Answer: Using traps or barriers. Physical barriers and devices directly remove or exclude pests.
Flashcard 22: What is the impact of monoculture on pest populations?
Answer: Increases pest populations. Single crop systems provide abundant resources for specialist pests.
Flashcard 23: What is one advantage of mechanical pest control?
Answer: Immediate reduction of pest numbers. Physical removal provides instant results without chemical residues.
Flashcard 24: What is the primary aim of chemical pest control?
Answer: To reduce pest populations using pesticides. Direct application of chemical compounds to kill or repel pests.
Flashcard 25: Which pest control method uses heat treatments?
Answer: Physical control. Temperature manipulation kills pests without chemical residues.
Flashcard 26: Which control method involves the use of sterile male pests?
Answer: Biological control. Sterile insect technique reduces reproductive success of pest populations.
Flashcard 27: What is the definition of integrated pest management (IPM)?
Answer: IPM is an ecosystem-based strategy focusing on long-term pest prevention. Combines biological, cultural, and chemical methods for sustainable pest management.
Flashcard 28: Which type of pest control focuses on minimizing habitat suitability?
Answer: Cultural control. Environmental modifications make conditions unfavorable for pest establishment.
Flashcard 29: What is the primary goal of ecological pest control?
Answer: To enhance ecosystem balance to manage pests. Works with natural processes rather than against them.
Flashcard 30: Which strategy involves using crop residues to control pests?
Answer: Cultural control. Plant debris management affects pest overwintering and reproduction.
