The objective of this study was to develop a rapid, real-time method for the detection of locusts.Near infrared spectra(NIR) in the range of 3996~12489.5cm-1 were recorded and the range of 3996~11502cm-1 was selected.Models were established by using the cluster analysis method.Different methods were compared.The study showed that complete-linkage model gave better results than single-linkage and other methods with the correctly classification rate of 91.67% for the test data set.Results indicate that NIR me...
