Control of Dacus ciliatus with pyrethroids
Dacus ciliatus (Diptera: Tephritidae – EPPO A1 quarantine pest) was discovered in 1997 in a limited area in Southern Negev, Israel (see EPPO RS 97/124). In laboratory studies and under quarantine conditions, it was observed that, unlike many other fruit flies, D. ciliatus was not affected by organophosphate insecticides. However, all tested pyrethroids (cypermethrin, fenpropathrin, bifenthrin) showed good efficacy against the adults when applied by surface contact or oral administration. It was also observed that piperonyl butoxide considerably increased the toxicity of pyrethroids. Further studies are now needed to identify a suitable attractant which could be used in combination with pyrethroids to control D. ciliatus.
