Bactrocera invadens (Drew, Tsuruta & White)

Scientific Name:
Bactrocera invadens
Describer:
Drew, Tsuruta & White
Title:
Update on the distribution of Bactrocera invadens – First find in Bhutan
Summary:

Significance: Within the last few years Bactrocera invadens has been rapidly spreading across Africa. A report also recently emerged that the fruit fly is in Southern India (http://www.pestalert.org/viewNewsAlert.cfm?naid=44). Drew et al. has now reported this pest in Bhutan (2007), marking a northeastern spread from the known distribution.

Issues of Concern: Bactrocera invadens poses a significant threat to many economically important fruit crops. It is also morphologically similar to Bactrocera (Bactrocera) dorsalis(Hendel), which is found in Southeast Asia, as well as Bactrocera (Bactrocera) kandiensis (Drew and Hancock), a native of Sri Lanka.
