Question: It is well known fact that, to slow down the growth of drosophila, they are grown at 18-19 degree Celsius. It helps in maintaining stocks for longer time without frequent change of food. Is it applicable to mosquitoes? especially *Aedes aegypti*? can we slow down its growth by growing them at lower temperature?

Answer: 
Check "[breeding temperature](https://www.google.fr/search?num=100&ei=MIhxWo_PGoz4kwXjp5-ACQ&q=%22breeding%20temperature%22%20mosquitoes&oq=%22breeding%20temperature%22%20mosquitoes&gs_l=psy-ab.3..0i22i30k1.12406.25620.0.25859.45.41.4.0.0.0.170.3738.31j9.41.0....0...1c.1.64.psy-ab..0.45.3859.6..0j46j35i39k1j0i67k1j0i46k1j0i20i263k1j33i160k1j0i13k1j0i13i30k1j0i13i5i30k1j0i8i13i30k1.80.wL5y7DSHlFM)" and similar obscure phrases for the search. 

There's a study on physical aspect of mosquitos bred in cold, they perhaps didn't note any significant metabolism change, you can read the articles, they mostly cover wing length scales and follicles.

There's a study on [lave development speed](http://server.ege.fcen.uba.ar/gem/pdf/Loetti%20et%20al.%202008.pdf) which passes over breeding temps, it may however cover "egg temperature".
Maybe: <https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3992806/> is a NIH paper that gives a quick overview on maintaining an A. aegypti colony. From the description they are somewhat fussy, but some of the lines imply temperature sensitivity at least at certain stages.
