Field evaluation of the relative attractiveness of enriched ginger root oil (EGO)lure and trimedlure for African Ceratitis species (Diptera: Tephritidae)

Mwatawala M.W., Virgilio M., Quilici S., Dominic M., De Meyer M.. 2013. Journal of Applied Entomology, 137 (5) : p. 392-397.

The males of some fruit flies (Diptera: Tephritidae) are known to be attracted to specific parapheromones. The trapping results between trimedlure (TML) and enriched ginger root oil (EGOlure) were compared at two experimental sites in Morogoro (Central Tanzania) for a period of 12 weeks co?inciding with the main citrus season. Both attractants captured a comparable diversity of fruit flies, except that EGOlure also attracted fruit flies, such as Ceratitis cosyra, not normally found in TML?baited traps. Both EGOlure and TML attracted mainly or exclusively male fruit flies, but the catches with EGOlure were equal or superior to those with TML. It is concluded that EGOlure should be considered as a suitable alternative for TML in detection, monitoring and control programs for African fruit flies of the genus Ceratitis. It has the added advantage that it combines the attractiveness with regard to species spectrum of both TML and terpinyl acetate.
