<p class="jove_title">Preparation in advance of microinjection</p>
<ol>
<li>Blood feed mosquitoes: for injection from Monday to Friday feed females on the previous Thursday.</li>
<li>Prepare glass needles using program 3 or 2 (see Materials).</li>
<li>Laying tube for the embryos is Drosophila culture vial. Wet cotton wool in the bottom, with a wet disk of filter paper covering it.</li>
<li>Prepare plastic cover slip by sticking double-side tape to one end. Trim tape to cover slip so that it ends at edge of cover slip.</li>

microinjection of a. aegypti embryos to obtain transgenic mosquitoes

In this video, Nijole Jasinskiene demonstrates the methodology employed to generate transgenic Aedes aegypti mosquitoes, which are vectors for dengue fever.  The techniques for correctly preparing microinjection needles, dessicating embryos, and performing microinjection are demonstrated.
