Future Thrusts for Development of Insect Sex Pheromones as Monitoring Tools
Monitoring pest populations with pheromone-baited traps has long been recognized as one of the major benefits of sex pheromone research. At first glance this technique seems simple enough. After all we have powerful synthetic pheromones, manufactured traps, and reasonably effective formulation systems. The problem lies in interpreting the trap catches. We find it difficult to estimate population sizes from the number of trapped insects. The season of the year, population level, plant host, weather conditions, and many other conditions affect our ability to extrapolate from our trapping sample to the whole population.
