Biology of Spodoptera litura F. on Colocasia esculenta.

摘要

The life cycle of Spodoptera litura was completed in shorter period on KCA-1 genotype. The larval, pre-pupal and pupal period were also shorter in KCA-1. The weight and size of larvae and pupae was highest in KCA-1. Similarly, larval survival, percentage pupation and adult emergence were maximum in KCA-1 compared to other tested genotype, indicating the preference for KCA-1 by S. litura. The genotype Panch Mukhi was found to be the least preferred genotype by S. litura among the four tested genotypes of C. esculenta..
