Suitability of Parts of Gram Plant for the Development and Growth of Heliothis armigera (H?bner) (Lepidoptera: Noctuidae)

The effects of the stem, leaf, flower and pod of gram plant on the growth and post-embryonic development of Heliothis armigera were investigated. During the investigation, the temperature ranged from 11 to 25?C and R.H. from 47 to 91%. The investigation revealed that the tested parts of gram plant behaved like different food. Plants; these parts differed in their capacity to support survival, development and growth. The stems failed completely to support these aspects; the flower prolonged larval period and also caused the poorest survival.
