Flight Traps

Proven insect flight collection traps made from sun-resistant polyester with double or triple sewn seams.

The Standard 6-Meter Malaise Trap

The Standard 6-Meter Malaise Trap Model 3012 is a flight trap with dual dry/wet collection heads. The traps were originally developed by Drs. Gressitt and Gressitt and we have been selling this trap for more than 20 years around the world. The fabric is sun-resistant polyester and all seams are double or triple sewn.

The Migration Trap

The Migration Trap Model 3212 is very similar to the Standard 6-m Malaise Trap but insects intercepted on each side of the baffle are captured separately allowing determination of flight direction.

The Light-Weight Townes Trap

The Light-Weight Townes Trap Model 3412 is about 2 meters long, made of sun-resistant polyester, and comes complete with a single aluminum and polypropylene wet-and-dry collection head.  This trap is also available as the Odonate Townes Trap Model 3419 with a collection head large enough to accommodate dragonflies (Odonata).

Adult Mayfly Updraft Blacklight (UV) Trap

The Adult Mayfly Updraft Blacklight (UV) Trap Model 3519 was developed for the capture of adult mayflies (Ephemeroptera) using a four-watt blue-blacklight (UV).  The three-inch diameter intake of the trap is at the lower end of the collection chamber and just above the blacklight tube.  The design is such that the insects do not go through the aspiration fan which is located at the top of the unit under the rain shield.

Other Traps

The John W. Hock Company over the years have built custom traps and devices for single users; usually by only word of mouth, others hear of them, order them, and they become part of our product line.  The Mayfly Updraft Blacklight (UV) Trap Model 3519 is an example from 2012; it was developed in concert with Matthew Green, a graduate student at North Carolina State University.  Another example is the Frommer Updraft Gravid Trap Model 1719 for collecting gravid Culex; this was developed in response to a request from Dr. Robert Frommer, formerly with the Manatee County Mosquito Abatement District in Florida for a Culex trap that produced pristine specimens as the catch does not go through the aspiration fan.  A third example is the Harris County Mosquito Abatement District’s (HCMAD) ruggedized Sewer Trap Model 519.55 in Texas; we developed this in collaboration with Dr. Ray Parsons, formerly director of HCMAD.  Their need was for a bullet-proof trap that would be suspended under the lid of storm sewers for catching their West Nile virus mosquito, Culex quinquefasciatus.  A final example is the Hamer Floating Emergence Trap for Catch Basins and Wells Model 619; this was developed in concert with another graduate student, Gabe Hamer while he was pursuing his PhD at Michigan State University.  Here is an article from the American Mosquito Control Association of this trap (Hamer et al. 2011. JAMCA) and a poster on the Floating Emergence Trap.

So if you have an idea, need something special or see a need, let us know!  Everyone benefits from collaboration.  If we think your idea has potential for others, we may add it to our product line and there is no developmental costs to you.
