First Old World Record of Cochliomyia Macellaria (Fabricius) (Diptera: Calliphoridae) from Bangladesh, with Notes on History of Tropical Myiasis and Routes of Introduction

The secondary screw-worm, Cochliomyia macellaria (Fabricius, 1775) is reported for the first time from the Old World. The single male specimen was collected in 2009 in Bangladesh, Dhaka, Gazipur District, and is deposited in the Canadian National Collection of Insects (CNC), Ottawa, Canada. The genus Cochliomyia Townsend, 1915, is endemic to the New World, except for the temporary occurrence of C. hominivorax (Coquerel, 1858) in Libya in 1988. An overview of myiasis cases prior to the description of the Old World primary screw-worm, Chrysomya bezziana (Villeneuve, 1914) is given and possible routes for the introduction of Cochliomyia macellaria into Bangladesh is discussed.
