Spatial distribution of legume pod borer, Maruca vitrata (Fabricius) (Lepidoptera: Crambidae) on Pusa 992 pigeon pea
cultivar during kharif (rainy season) 2011 and 2012 was analyzed through Taylor’s power law (TPL) and Iwao’s mean
crowding (IMC) regression. M. vitrata exhibited an aggregated distribution pattern on the crop. The pooled data for the
two years fitted well to the TPL (a D 1.05, b D 1.19, R2 D 0.967) and the IMC (a D ¡0.17, b D 1.124, R2 D 0.99). The
optimal sample sizes with the TPL parameters increased with an increased precision level. Based on the TPL parameters,
the decision lines of sequential sampling for M. vitrata were determined to be d D 3n § 2.5xn. The sequential sampling
plan would economize decision-making for an effective management of M. vitrata.
