Abstract
In this study, a mathematical model is made to estimate the median lethal
concentration or dose (LC50 or LD50). The model is based on the data of different
insecticide groups, where each one is represented by the effect of three insecticides
over different orders of insects by using different application technique. The trend of
change of the LC50 or LD50 is observed among the insect life cycle for each group of
insecticides. It is shown that for an insecticide group, there is a clear trend for the
change of the LC50 (or LD50) when going from an age stage to another. That trend is
simulated for each group to predict the LC50 or LD50 at an age stage by knowing it at
another stage and method of treatment used.
