Technical Abstract: Insect traps are used for general survey of insect diversity, for detection of new invasions of insect pests in time and/or space, for delimitation of area of infestation, and for monitoring population levels of established pests. This information is used to make decisions on the initiation of control measures or to measure effectiveness of a pest management program. Traps for specific insect species or pest groups use combinations of cues to lure the target insect and exploit aspects of the insect's behavior to facilitate movement of insects into the trap. Several factors influence the effectiveness of a specific trap. The ability of the trap to mimic and present those cues to the insect; the strength of those cues in influencing the insect's behavior, and the proper placement of the trap in the habitat are all important. We present an overview of the basic trap types and variations of those basic trap types for specific uses. These may be used with or without attractant cues. We then discuss traps used in combination with a variety of cues, including visual, chemical and acoustic, to make them more specific and/or more effective. Several automated monitoring systems that will transmit information on trap capture to an off-site station are then described. Finally, the use of insect traps as part of an insect pest management program, both for monitoring and for control, are discussed.
