Malaise Traps

The Malaise trap, developed in the 1930s by Swedish entomologist Dr. René Malaise, is a crucial tool for passive insect sampling in entomology.  Its tent-like design features a sloping roof and a vertical mesh baffle that directs flying insects into a collecting bottle filled with a preservative solution.  This trap is particularly effective at attracting Hymenoptera and Diptera.  Recent innovations, such as BugDorm's SLAM Trap (Sea, Land, and Air Malaise Trap), enhance portability and adaptability, making it suitable for various habitats, including forest canopies and open bodies of water.  Additionally, the ez-Malaise Trap simplifies setup, making it convenient for research in remote locations and rugged terrains.
