Abstract: The author reports in this paper that mistakes have been found in "The Model of the Dynamic of Insect Population and Its Graph Theory" after his examination. The mistakes were mainly made in the following four aspects:1. The replacement of forecasting equation by the random difference equation.2. The use of the three examples as evidence taken from the known sample series to forecast the sample series itself.3. The inconformity of problems discussed with the mathematical model.4. Definition of each interval period of growth phases according to the metamorphoses of insects.
