Final answer:
The most important factor affecting the rate of blowfly stage development on a corpse is the mortality rate during specific developmental periods. This hypothesis can be tested by constructing a life table and calculating mortality rates at different age intervals.
Step-by-step explanation:
The most important factor affecting the rate of blowfly stage development on a corpse is the mortality rate during specific developmental periods. Research proposals suggest that the mortality rate might be high before or after sexual maturity is reached. This hypothesis can be tested by constructing a life table and calculating mortality rates at different age intervals. Additionally, factors such as temperature, availability of food, and other environmental conditions can also influence the rate of stage development.
