Investigation was carried out at Entomology Department, B. A. College of Agriculture, Anand Agricultural University, Anand on variations in morphometric traits of susceptible and resistant populations of pigeonpea pod borer, Helicoverpa armigera (Hubner) Hardwick collected from different districts viz., Anand, Ahmedabad, Dahod and Vadodara of middle Gujarat studied during the year 2015-16 and 2016-17 The result showed that the larval and pupal, lengths and weights of H. armigera were significantly more in case of Vadodara and Ahmedabad district populations as compared to Anand and Dahod district populations as well as laboratory reared susceptible strain. The lengths of the femur and tibia for each leg as well as lengths and widths of both wings of Vadodara, Ahmedabad, Anand and Dahod district populations were found slightly more than the adults of susceptible strain. | Morphometric variations between susceptible and resistant population of helicoverpa armigera Hubner hardwick in pigeonpea from the different locations of middle gujarat
