Spatial pattern of egg plant shoot and fruit borer, Leucinodes orbonalis Guen. (Lepidoptera: Pyraustidae) larvae
Published online by Cambridge University Press: 19 September 2011
Abstract
Studies conducted on the spatial pattern of Leucinodes orbonalis Guen. larvae at the Experimental Farm, Barapani of ICAR Research Complex for NEH Region, Shillong revealed that they follow positive binomial distribution within plant, shoot and fruit. The larvae were distributed as negative binomial (contagious) within plot (2 × 2 m) at all stages of sampling except during initial and last stages of crop where they follow positive binomial distribution. The possible reason for this change in distribution may be due to comparatively lower larval densities at initial and last stages of crop.
Résumé
Cet article présente les résultats obtenus concernant spatia pattern du Leucinodes orbonalis Guen. larvae à ferme des Complex ICAR De La Recherch, Shillong, Indie ces observations ont permis certain points. La distribution du larvae sur les plante et les fruits ont positive binomial. La distribution sur les plots ont positive binomial que pendant stage initiale et finale parce que le population des larvae ont moins à stages initiale et finale.
