I have some suggestions
1 don’t use the shadow effect on the figures
2 add the discussion and in your own words, talk more about your findings specially regarding prepupa because are the once we know can be induced to diapause, you can talk about at what temperatures they will be induced in diapause, and how can you brake the diapause
3 organize your results separate by stage, foe example,
eggs died at(which temperature) and survive at….
Larvae died at(which temperature) and survive at….
prepupa died at(which temperature) and survive at…. Then add what you found. They reduce their size as well right? I believe you have very good observations because you mentioned to me, do the same in your report.
