  • Spatial distribution and occurrence of Anophia leucomelas Linnaeus larvae in sweet potato fields was studied in 2015. A mathematic model for proper sampling was established using 6 gathering intensity indices,Taylor's power law, and Iwao'sm*-m regression methodolgy. The larvae appeared to have the pattern of assembling distribution in the fields. Their aggregating intensity increased with population density, and was due mainly to the environmental factors. Base on the data collected, a theoretical sampling number could be derived from the equation:N=1.962/D2(1.3102/m+0.6255), and the Kuno's model for sequential sampling:Tn=1.3102/(D2-0.6255/n).
