Spatial Distribution of Spodoptera frugiperda (JE Smith) (Lepidoptera: Noctuidae) on Corn Crops in Durango, Mexico

Accurately determining the spatial distribution of an insect is crucial for making effective decisions and efficiently controlling their populations. This study aimed to determine population Spodoptera frugiperda (J. E. Smith 1797) (Lepidoptera: Noctuidae) larvae in corn plots near City Durango, Mexico. A total 30 corn-cultivated were sampled. In each plot, 5 points selected (5 coins method), where 10 consecutive plants these phenological stages V4 V10 checked presence recorded. Statistical analysis was conducted using Scattering Indices 2/χ2 Chi-square test (χ2). The results indicated that infestation slightly higher during stage V6 than V8. S. had a negative, aggregate, or binomial only (corresponding small larvae), while other stages, random.
