The sporogonic stages of Plasmodium berghei (NK 65) were studied in Anopheles stephensi under a scanning electron microscope. Banana shaped ookinetes were observed from 12 h post-feed mosquitoes. Each ookinete had a small protuberant 'conoid' at the anterior end. The surface of the ookinete was smooth. The development of oocysts was asynchronous. Immature oocysts had smooth walls and mature ones had wrinkled surfaces. The oocysts had no specific pore or opening for liberation of sporozoites. No morphological difference was observed between the sporozoites of oocysts and those of salivary glands except size variation.
