Title

BIOLOGICAL ACTIVITY OF CYMBOPOGAN WINTERIANUS AND ALOYSIA CITRODORA LEAVES EXTRACTS AGAINST THE BLACK CUTWORM, AGROTIS IPSILON (HUBN.) (INSECTA: LEPIDOPTERA: NOCTUIDAE)

Abstract

Abstract: Black cutworm has a wide host range. A.ipsilon is a worldwide cosmopolitan pest over 30 important crops. However, larvae feed above ground until about the fourth instar. Present study was undertaken to evaluate the bioassay test of Cymbopogan winterianus and Aloysia citrodora plant extracts against A.ipsilon. Larvae were collected from Chincona village of Nilgiris.The study was conducted in the laboratory to evaluate the Cymbopogan winterianus and Aloysia citrodora plant extracts with different concentrations (0.5%, 1% and 2%). The biological activity was recorded of 24hrs under laboratory condition. The larval antifeedant activity was 85.45% and 90.35% in 4th instar larvae of A.ipsilon after the treatment of Aloysia citrodora and Cymbopogan winterianus plant extract at 2% concentration. Whereas 4th instar larval mortality was 90.42% and 98.32% after the treatment of Aloysia citrodora and Cymbopogan winterianus extract at 2% concentration. The pupal mortality was 85.36% and 94.15 at 2% of Aloysia citrodora and Cymbopogan winterianus extract. The larval duration of 4thinstar larvae of A.ipsilon was greatly extended after the treatment of Cymbopogan winterianus (9.02 days) than Aloysia citrodora (6.95 days ) at 2% concentration. The Pupal duration also extended after the treatment of Aloysia citrodora (13.56 days) and Cymbopogan winterianus (15.74 days) at 2% concentration. The fecundity also significantly reduced after the treatment of Aloysia citrodora and Cymbopogan winterianus and also recorded in adult longevity of A.ipsilon. The study was also conducted the nutritional indices of IV instar larvae of A.ipsilon after treatment of Aloysia citrodora and Cymbopogan winterianus extract. The Cymbopogan winterianus plant extract was more effective than Aloysia citrodora extract on larvae of A.ipsilon . High bioactivity was observed in the doses against Cymbopogan winterianus the greasy cutworm, A.ipsilon such result may offer an opportunity for developing alternatives to rather expensive and environmentally hazardous in organic insecticides.
