Principal component analysis (based on the correlation matrix, eigenvalues > 1.25) of different parameters, such as the percentage reduction of S. frugiperda in Kharif (RKS) and Rabi (RRS) sown crops. PCA on the larval population of S. frugiperda on ten plants at pre and post-treatment in Kharif (PKP, PKS) and Rabi (PRP, PRS) sown crops and leaf damage score caused by S. frugiperda at pre- and post-treatment in Kharif (LDKP, LDKS) and Rabi (LDRP, LDRS) sown crops
