Attraction of neonate Helicoverpa armigera (Hübner) (Lepidoptera: Noctuidae) larvae to different host plant volatiles

Ragesh PR, Satish Ganta, Indrakant K. Singh, Ashok K. Singh

The orientation responses of 1st instar grampod borer Helicoverpa armigera larvae to the green leaf volatiles of three leguminous crops; pigeonpea, Cajanus cajan; mungbean Vigina radiate and blackgram Vigina mungo were determined in no-choice and two-choice tests under laboratory conditions. The larvae showed positive orientational responses to the leaves of all the three test plants. However, larvae attracted more towards the pigeonpea as compared to blackgram and mungbean in no-choice and two choice conditions. The results clearly indicate that the first instar H. armigera larvae showed higher attraction towards the volatiles of pigeonpea followed by blackgram and mungbean. Role of such host plant volatiles in eliciting the orientational responses of pod borer larvae will be useful in understanding the establishment and subsequent damage by the larvae which further helps in developing efficient management strategies.
