Subject: New invasive fruit fly, Bactrocera (Bactrocera) invadens, extends its distribution and host range across Africa
Date posted: April 27, 2005
Source: African Entomology

The newly described species Bactrocera (Bactrocera) invadens has quickly spread across tropical Africa since it was recently discovered in eastern Africa in 2003.  Bactrocera invadens is morphologically similar to Bactrocera (Bactrocera) dorsalis (Hendel), found in Southeast Asia, as well as Bactrocera (Bactrocera) kandiensis (Drew and Hancock), a native of Sri Lanka.  The fruit fly appears to be from the Indian subcontinent and was only discovered in Sri Lanka after it was first detected during surveys in Africa. This new species of Tephritid fly is causing significant economic damage to crops such as guava (Psidium guajava L.), mango (Mangifera indica L.), citrus (Citrus sp.), papaya (Carica papaya L.), and other wild hosts in Africa.  This pest has now been recorded from the following African countries in sequence: Kenya, Tanzania, Sudan, Benin, Uganda, Cameroon, Togo, Senegal, Ghana, and Nigeria.
