Description

The present study reports Megaselia scalaris (Loew, 1866) as a facultative endoparasitoid of the Bombay
locust, Patanga cf. succincta (Johannson, 1763) for the first time. This case of parasitism was observed inside the
insect box where the recently collected locust was stored. The life cycle of the scuttle fly, which was studied till
the adult emergence, is described. The results of this study may help us to understand M. scalaris as the natural
enemy of the Bombay locust. It may also generate fresh concepts for integrated pest management strategies.
