Insect traps for monitoring and control
Insect traps are useful tools for monitoring insect populations to determine the need for control or the timing of control practices. In some instances, attractants and traps also can be used to control insect populations directly by mass trapping or mating disruption. Mass trapping is most likely to be effective when the density of the target pest is low and immigration into the trapped area is minimal, as is the case in restricted environments (e.g. greenhouses).
Insect traps consist of a visual (colour, shapes and light) and/or chemical (scent) attractant to attract the target insect, plus a device to capture the insect once it arrives. Most insect traps either use glue to immobilise insects or have funnel structures to prevent them from escaping.
