摘要

The ThermaCELL with allethrin and OFF! Clip-on with metofluthrin were tested in a 939 m(2) vented enclosure against nymphal lone star ticks, Amblyomma americanum (L.). Repellency assays were conducted at varying distances relative to product specifications for repellency range. Nymphal ticks acclimated for 24 h in chambers attached to 10 repellency tracks per repetition. Devices were turned on, and the tick travel distance and delay until beginning to travel were recorded. Mortality of ticks was recorded after 24 h. Mortality assays were also conducted at the same distances with five ticks per cage, and 12 cages per distance radially distributed around a device. Cages were removed after 5 min, 15 min, 30 min, and 60 min of exposure and checked after 24 h for mortality. Significant travel distance was found when exposed to the ThermaCELL and OFF! Clip-on at their shortest test distances. Significant mortality also resulted at the same distances. Ticks exposed to active devices for longer than 15 min had significant mortality at the shortest distance for OFF! Clip-on and multiple distances for the ThermaCELL. Overall, the spatial repellent devices ThermaCELL with allethrin and OFF! Clip-on with metofluthrin both demonstrated desirable effects when tested against A. americanum nymphs.
