The goals of using semiochemicals in pest control are
# to monitor pest populations to determine if control is warranted and
# to alter the behavior of the pest or its enemies to the detriment of the pest. In general, the advantages of using semiochemicals are 
## they have adverse effects only on target pests, 
## they are relatively nontoxic and required in low amounts, 
## they are nonpersistent and environmentally safe 
## they appear difficult for insects to develop resistance against. Monitoring of pest populations with pheromones is often integrated in management programs.
