What role does pheromone trapping play in pest management?

• A. It increases pesticide utilization
• B. It monitors pest populations and disrupts mating
• C. It attracts beneficial insects
• D. It enhances crop growth

Answer: (B)

Pheromone trapping serves a crucial role in integrated pest management by monitoring pest populations and disrupting mating behaviors. Pheromones are chemical signals used by insects to communicate, particularly in attracting mates. When traps baited with synthetic pheromones are used, they can effectively capture male insects, thereby reducing their ability to mate with females, leading to a decrease in pest populations over time. This method also serves as a monitoring tool, providing valuable data about the presence and abundance of specific pest species. By understanding the population dynamics through these traps, growers can make informed decisions regarding the timing and necessity of additional pest control measures, such as applying pesticides. The dual purpose of monitoring and mating disruption makes pheromone trapping an effective, environmentally friendly strategy within the broader framework of pest management, as it helps minimize reliance on chemical insecticides while keeping pest populations in check.
