“…Also, the growth and survival index values became low when reared on leaves and squares compared to young bolls and mature bolls. These results are in accordance with those of earlier workers (Rupnar, 2018;Hallad et al, 2011;Likhitha andBhamare, 2018, Mahalakshmi andPrasad, 2013;Naik et al, 2012). Among the different public sector Bt cotton hybrids superior results were expressed by PKV Hy-2 BG II when H. armigera larval instars fed on leaves and squares at 60-80 and 90-110 days old crop, respectively and NHH-44 BG II when fed on young bolls and mature bolls at 120-140 and 150-170 days old crop, respectively.…”

Laboratory experiment was conducted to find out the survival and development of Helicoverpa armigera (Hubner) on public sector Bt cotton hybrids (NHH-44 BG II, PKV Hy-2 BG II, PDKV-JKAL-116 BG II, G. COT-10 Hy. BG II and G. COT-08 Hy. BG II). Instarwise observations were documented on leaves, squares, young bolls and mature bolls at 60-80, 90-110, 120-140 and 150-170 days old crop, respectively. The results revealed that the early instars of H. armigera exhibited higher larval mortality than the later instars. The surviving larvae revealed adverse effect on many parameters viz., larval and pupal weight, % pupation and adult emergence indicating low growth and survival indices.
