    Study on the Spatial Distribution Patterns of Nephopteryx sp. Larvae and Sampling Methods

    • The spatial distribution patterns of larvae of Nephopteryx sp. were studied by means of aggregation indices and Iwao's regression model. The result showed an aggregation distribution pattern for the larvae and a uniform distribution for the fruit damaged by the larvae. With the different sampling methods compared, it was found that random sampling method was the best.
