Bionomics is indeed the 'thorough' study of living organisms and their relationship with the environment/ niche they thrive in.
Aim of Bionomics is mainly to decipher the driving factors for an organism to prefer a given niche. Given this key goal, it is apparent that one needs to focus on all aspects of an organism's life cycle and community dynamics.
So the answer to your question would be: Yes, one will need to focus on all the five points pertaining to Anopheles sp. (the 5th point i.e diseases caused) will more be an information resulting out of the study of its interactions with other living/ non-living forms), than a specific focal point for Bionomics.
