Integrated Pest Management (IPM)
Dehydration (with diatomaceous earth): when in contact with any insect, in any development stage, it causes erosion of the exoskeleton resulting dehydration and eventually the insect’s death. It is a highly safe, efficient and economic pest control practice when dealing with insects, storage mites, house insects (fleas, bedbugs, ants, cockroaches) and even harmful wood infesting insects such as termites.
Pressure: a. High pressure b. compressed dry air
Drying: exposure to the sun or to an autoclave
Mechanical movement i.e sieving
Void: Total or high and continuous void
Asphyxiation: mixing seeds with oil
Washing using water
Heat: a hot current of air is preferred when dealing with products whereas hot water or steam is better for means of transport, tools and machinery.
Cold: Mostly on fresh fruit in order to control Diptera in their early development stages.
Electrostatic Field: i.e. a machine that electrocutes dry wood termites at 90 watts, 90,000 volts and a frequency of 100 kHz. without raising, at the same time, the temperature of the material processed
Irradiation: sterilizing products for immediate consumption by humans mostly with gamma rays and infrared radiation.
Through the use of insect-statics, we can “dilute” the density of the population of harmful insects to the point where no stored products are completely destroyed and there is no significant economic damage. Decreasing the number of insects in a certain space in order to avoid chemical treatments is what we call insecti-stasis.
Phototropism (electrical traps)
It is applied with the use of light traps and it is based on what is called positive phototropism. It is used for the collection and determination of insects moving through closed up spaces as well as for the reduction of mostly flying insects.
Pheromone Traps
Pheromones are a means of chemical communication between members of the same species. They include sex pheromones, aggregation pheromones and alarm pheromones.
