FROMMER UPDRAFT GRAVID TRAP MODEL 1719

The Frommer Updraft Gravid Trap Model 1719 operates in a fashion similar to the CDC Gravid Trap (Model 1712) by creating an upward current of air from within the confines of the oviposition pan, so that the mosquitoes are drawn into the unit during their pre-oviposition examination of the medium. The chief advantage of the 1719 over the 1712 trap is that the Frommer version has a collection chamber below the fan and the adults are not exposed to the aspiration fan; the result is pristine specimens that are easy to identify. A second important feature of the Frommer Updraft Trap is the inclusion of two complete collection chambers; this means once-a-day tending. After collecting one night, visit the trap any time in the next day with the second collection chamber, remove the first chamber with last night’s catch, insert the second chamber and attach the battery. Return to the lab with the first day’s catch/chamber and process. This trap was developed and evaluated with the aid of Dr. Robert Frommer of the Manatee Mosquito Control District of Florida.
