Abstract

This study on the Helicoverpa armigera (Hubner) was carried out in rabi 2020–21 at the College of Agriculture, Campus Latur, at the Post Graduate Experimental Field of the Department of Agricultural Entomology. The findings showed that H. armigera passed through two generations on safflower. The mortality in early instar larvae of H. armigera infesting safflower was found to be 11.11 and 19.44 % due to infection of HaNPV during the first and second generations, respectively. However, during the second generation, early instar larvae also died to the tune of 10.34 % due to parasitisation of Campoletis chlorideae. The mortality in late instar larvae was found to be 25.00 and 21.73 % due to HaNPV during the first and second generations, respectively. However, late instar larvae also died to the extent of 11.53 and 5.54 % due to unknown reasons and C. chlorideae, respectively. During the first and second generations, pupal mortality was found to be 33.33 and 41.15%, respectively, due to unknown reasons. The trend index and generation survival were 1.33 and 0.44 and; 0 and 0.27 during the first and second generations, respectively.
