Weeks 4-6 at PDPH
While on the field, my supervisor taught me and the other interns how to differentiate mosquito larvae from a glance before taking a closer look. We took dips of various bodies of stagnant water, things such as tires, water basins, plastic bins, garbage left standing upright, and puddles of varying sizes. Every week we took 10 dips all around the city to send it to a lab so that there would be a record of what types of mosquitos were prevalent in specific areas. From a distance, if there are many mosquito larvae they may look like small dots in the water, and upon closer inspection we found that larvae spasm as they move and look like (in my opinion) sharp and prickly worm-like insects. By just looking at the mosquitos in their larval stage, we were able to venture a guess as to what the species of mosquito was and what it would look like if it were to hatch into an adult. Some presented light brown or yellow colorings, some were a darker brown or almost black color. (...
