Insect pheromones and their use in Integrated Pest Management (IPM)

• Pest monitoring

• Mass trapping

• Lure and kill

• Mating disruption

 

Pheromone and IPM

·       Pheromones can be utilized to catch or deter insects. Example: Pheromone “traps”, which contain the pheromone emitted by the female gypsy moth can be set to catch male moths

 

Definition

·       Pheromones are chemicals emitted by an animal that signals another animal of the same species. Example: female gypsy moths emit a pheromone to attract a male

 

Pheromones:

semiochemicals released by an indand affect other ind within the same species (intraspecific effects)

·       Aggregation Pheromones: release by ind of one species that attract conspecific ind to the source organisms (e.g. stinkbugs)

·       Alarm Pheromones: elicit escape and defensive behavior. (e.g. Ants)

·       Sex Pheromones: involve with attraction between sexual partners to increase mating probability. Emitted by one sex, to attract opposote sex (e.g. moths, butterflies)

·       Other Pheromones: Trail, maturation, epidiectic (dispersal)
