Spatial distribution pattern of larvae of Aleurocanthus spiniferus in citus garden was studied by means of some distribution parameters such as mean crowding, David and Moor's clustering index, index of patchiness, proliferation index, the distribution of negative binomial, Iwao's patchiness, the and Taylor's law. The results showed that the spatial distribution pattern of larvae under all densities appeared to be aggregation distribution, which is characterized by individual attraction and predominant individual group such as cored distribution pattern.

In conjunction with MICQ, a nephogram clustering algorithm based on PSO is proposed, of which the coding and fitness function are projected. In addition, nowadays, many researches of nephogram classification usually focus on some single feature, and the classifications are achieved based on these unique features, correspondingly. This strategy would probably ignore the potential which is provided by the combined classification based on multiple features.
