【Background】Rhynchophorus ferrugineus (Olivier) is an alien and dangerous insect pest, which had been attacking various palmaceous plants and had led to a vast loss in southern China in the past ten years. 【Method】This paper deals with the spatial pattern and relevant parameters in the larval population of R.ferrugineus by means of field investigations, aggregation index and regression analysis methods. 【Result】In the Iwao′s model, the parameters α=0.4208＞0，and β=1.5133＞1, indicated that R.ferrugineus larvae showed an aggregated distribution pattern in the field. Taylor power law analysis indicated that the larvae spatial pattern was aggregated, due to mutual attraction among individuals. 【Conclusion and significance】R.ferrugineus larvae are highly aggreagated in the field in China, which requires an optimal sampling and sequential sampling model for field investigations.
