Population Dynamics of Castor Insect Pests in Relation to the Weather Parameters of Southern Telangana Zone

Castor (Ricinus communis L.) is an important oilseed crop of dry land area with huge industrial importance. However, biotic stresses are becoming major bottleneck in yield improvement. In view change insect pest status current agricultural scenario and fluctuations climatic conditions will influence the incidence severity pests. Keeping this point studies on population relation to weather parameters was carried out assess pests castor during kharif, 2020 at Regional Agricultural Research Station, Palem relationship between parameters. Which revealed that leafhoppers have shown positive significant association maximum temperature (r=0.48) negative minimum (r=-0.59), evening relative humidity (r=-0.56). rainfall (r=-0.60). Thrips has (r=-0.65). Semilooper a correlation (r=0.17). Spodoptera litura exhibits (r=0.24), Percent capsule damage by borer had (r=-0.49) (r=-0.55).
