A field population of fall armyworm Spodoptera frugiperda (J.E. Smith) after toxicological bioassays, was subjected to laboratory selection with chlorantraniliprole and flubendiamide to investigate how resistance develops. The S. frugiperda field population from Multan (Mt Field-Pop), Pakistan, at second generation exhibited moderate resistance to chlorantraniliprole (27.48-fold) and flubendiamide (20.77-fold), very low resistance to abamectin and fenoxycarb (7.9-fold), but high resistance to lufenuron (78.3-fold) and pyriproxyfen (96.8-fold) compared to a laboratory susceptible population (LAB-SUS). Selection of S. frugiperda with chlorantraniliprole and flubendiamide over 10 generations resulted in the development of 198.7-fold and 136.5-fold resistance to these insecticides, respectively. The realized heritability (h2) of resistance to chlorantraniliprole and flubendiamide in S. frugiperda was estimated at 0.15 and 0.16, respectively. Selection for chlorantraniliprole resistance increased the resistance by 22.3-fold for flubendiamide, 17.5-fold for abamectin, and 10.9-fold for pyriproxyfen, but had no effect on resistance to lufenuron and only a slight increase in resistance (2.4-fold) to fenoxycarb. Similarly, selection with flubendiamide increased resistance to chlorantraniliprole (31.9-fold) but did not lead to resistance development against the insect growth regulators (IGRs) lufenuron, pyriproxyfen, and fenoxycarb. The inheritance analysis of chlorantraniliprole and f...
