Dissection of Midgut and Salivary Glands from Ae. aegypti Mosquitoes

Overview

This video demonstrates dissection techniques for removing the midgut and salivary glands from Aedes aegypti mosquitoes, which are critical for studying vector pathogens like Plasmodium falciparum and the dengue virus.

Key Study Components

Area of Science
