Adebayo and Akinbola, 2014, Distribution pattern and host preference of African invader fly, Bactrocera invadens (Drew, Tsuruta and White) [Diptera: Tephritidae] in Akure and its environs, Molecular Entomology, Vol.5, No.7 1-6 (doi: 10.5376/me.2014.05.0007)

The presence, distribution pattern and host preference of the African Invader Fly, Bactrocera invadens (Drew, Tsuruta and White) was studied in three different locations in Akure and its environs, Federal University of Technology Akure (FUTA), Federal College of Agriculture (FECA) and Ipogun (Ondo State, southwestern Nigeria) on mango, citrus and pawpaw for a period of eight weeks. Trapping of the fruit flies was done using fabricated plastic bottle traps baited with Methyl Eugenol (ME) (4-allyl-1,2-dimethoxybenzen) pre-mixed with insecticide, Plan D. The flywas present in the three locations sampled throughout the study period. Average value of the fly obtained revealed that Bactrocera invadens was most abundant at Ipogun village compared with FECA and FUTA and was significantly different at p > 0.05. The result also showed no significant difference in the number of catches at FECA and FUTA, but showed significant difference in Ipogun throughout the period of the study (p > 0.05). Pattern of catches was also observed to increase with the number of weeks on all the hosts at the three locations. The computed mean density of the fly in the various locations showed that number of fly caught was most on the mango host than citrus and pawpaw, though, no significant difference was observed between the three hosts at the end of the eight weeks. This study has provided information on the presence, distribution pattern and preference for already identified hosts within the region. It is therefore recommended that continuous monitoring of the fly’s population be initiated, while the comprehensive control measure is urgently required.
