During module 7 you learned about various fly species which are important to forensic entomology. In a few weeks, you will learn how to use the developmental time of these species to estimate a time of colonization interval. In order to do that, however, you must be able to find developmental data on these species. That brings us to this writing assignment. You are going to begin to build your developmental data library, and aggregate that data into a usable table.
At the bottom of this assignment, you will see a list of ten common forensically important species. Using the library web site, Google Scholar, or any other resource you may have, find, for each of these species:
- The developmental time necessary for each species to develop through the egg stage, first instar, secondinstar, third instar, pupal stage, and fully develop from egg to adult (total developmental time)at four different temperatures (these temperatures are up to you, based on the references you have found)
- The developmental threshold for each species
- The season in which the fly is most abundant
- The approximate geographical range of each species
Once you have your references, create a table of your species summarizing the developmental time and threshold. Include each developmental stage (egg, first instar, second instar, third instar, pupa, adult) in your table. See the example table below. Below the table, write out the known range for the insect, and its seasonal preferences within its known range. Each species should have its own table. Make sure to reference where you got this information.
Note: Some species are well studied, while others are not. If you find more than one paper outlining the developmental data of a species, include it. If you only find minimal data on a species, include what you can.
Put the tables and information about each species in a PDF document to turn it in. (Yes, it's going to be easiest to do this in Excel, but Canvas doesn't display Excel files very well, which will make this extremely difficult to grade). At the end of your document, have your bibliography including all of the references you used to create your tables.
UseESA format(Links to an external site.)to reference your articles both inline and in the bibliography. You will need a minimum of 12 references for this assignment. I will use the attached rubric to grade your submissions. Good luck! Here’s the list of species
Cochliomyia macellaria
Chrysomya rufifacies
Chrysomya megacephala
Phormia regina
Lucilia sericata
Lucilia cuprina
Pollenia rudis
Calliphora vomitoria
Calliphoria vicina
