Pheromone Lures and Traps
|
Sex Pheromones
Adult female insects that are ready for mating, emit species-specific chemical odours to attract males. This method of utilising pheromones - produced by insects for their procreation - as tools for their destruction, was first introduced in India by PCI. Lab-synthesised pheromones are specially packed and supplied as lures, to be used along with suitable traps to deceive, attract and trap male insects.

Monitoring
Installation of traps with suitable pheromone lures @ 2-3 per acre can provide information on pest incidence and intensity in agricultural fields. Based on the number of males caught, the timing and frequency of control measures can be determined.
|
|
Mass Trapping
Sex pheromones and traps can also be used as a device for reducing the population of target pests. The majorities of females present in cropped fields remain unmated and lay infertile eggs as a result of mass trapping of males.
|
|
Aggregation pheromones
Insects also produce chemicals to call others to a location, for e.g. when a food source is located. These are called aggregation pheromones and can be effectively used to trap both males and females since both sexes respond to the chemical signal.
