Evaluation of a metofluthrin fan vaporizer device against phlebotomine sand flies (Diptera: Psychodidae) in a cutaneous leishmaniasis focus in the Judean Desert, Israel

Abstract

The OFF! Clip-On fan vaporizer device releasing metofluthrin was evaluated against phletobomine sand flies in the Judean Desert, Israel, in October, 2009. A total of 76,400 sand flies was collected, with male flies representing 98.3% Phlebotomus sergenti and 1.7% P. papatasi. Females comprised 43.0% of the total catch and included 6.7% blood-fed females. Similar proportions of flies were collected in both suction and sticky traps. In trials with unbaited suction traps, similar numbers of sand flies were collected in traps with a metofluthrin device, blank device, or no device (i.e., suction only). In suction traps baited with CO 2 , higher numbers of P. sergenti males and blood-fed females were collected in traps with a blank device compared to traps with a metofluthrin device. In sticky traps baited with CO 2 , there were no significant differences between catches in traps with a metofluthrin device, blank device, or no device. The results suggest metofluthrin from the device is not repellent against sand flies in a field environment despite showing insecticidal activity against flies collected in suction traps.

Field Evaluation of Four Spatial Repellent Devices Against Arkansas Rice-Land Mosquitoes

“…Clip-On. In the 1st study, Zollner and Orshan (2011) evaluated this device against phlebotomine sand flies in Israel. They used both suction and sticky traps.…”

“…There are many commercially available spatial repellent products currently on the market. These products include impregnated plastic or paper strips (Argueta et al 2004;Kawada et al 2005Kawada et al , 2008, coils (Jensen et al 2000, Ogoma et al 2012, candles (Muller et al 2008), fan emanators (Zollner and Orshan 2011), and heat-generating devices (Alten et al 2003, Collier et al 2006. Although much interest exists regarding the efficacy of these products, very few scientific studies, especially in the field against natural populations of mosquitoes, have been conducted.…”

Comparative Field Evaluation of Different Traps for Collecting Adult Phlebotomine Sand Flies (Diptera: Psychodidae) in an Endemic Area of Cutaneous Leishmaniasis in Quintana Roo, Mexico

“…The sticky trap has been evaluated under field conditions with a variety of designs. For instance, sticky traps were evaluated with blue and yellow colors baited with synthetic sex pheromones (Bray et al 2010), host odor (Oshaghi et al 1994), CO 2 in horizontal position (Moncaz et al 2013), or with CO 2 paired with a metofluthrin (Zollner and Orshan 2011), and colored chemical light sticks (Burkett et al 2007), with and without lights (Veronesi et al 2007). Another method of capture is the delta trap, which is mainly used for economically important insects, usually combined with sex pheromones (Barrera et al 2006).…”

Effects of the spatial repellent metofluthrin on landing rates of outdoor biting anophelines in Cambodia, Southeast Asia

“…Whether this was because of a repellent or a killing effect was not known. The efficacy of metofluthrin as a repellent may also differ among species or families as it apparently has little or no effect against Culicoides (Diptera: Ceratopogonidae) (Zoller & Orshan, ). Recently, emanators that should be effective for longer than previous emanators have been developed.…”
