Abstract
Investigations on biometrical analysis, growth and life tables of Heliothis armigera Hubner on different hosts via,, chickpea, cotton, groundnut, tobacco and wheat were carried out during 1980 to 1983 at the Department of Entomology, B.A.College of Agriculture, Anand either in Laboratory or under field conditions, Studies on biometrical analysis were carried out to test the applicability of Dyar's law to the larvae of H. arimigera, when reared on different hosts. The measurements of head capsule width (mm) of the larvae fall into five well defined groups, when the larvae were fed on chickpea, cotton, tobacco and wheat,whereas six distinct groups were recognised on groundnut at a constant temperature of 26 ± 1°c.
