Abstract:In this summa, the state-of-the-art in sampling technique of insect populations are reviewed. The theory and practice of the sampling technique for insect populations were summarised, On sampling for estimating population abundance, the sampling scheme and data analysis, selection of sample unit, calculation of optimum sample size and simplified estimation method (estimating population defisity from relationship between zeroquardt frequence & population density) were reviewed respectively. Also the Risk Decision Sampling (Sequential Sampling) and Simpli-fied Sequential sampling (Presence-Absence Sequential Sampling) were approached.
