Attempts have been made to examine the trends and forecasting in area, production and productivity of cotton crop in three districts of Northern Telangana Zone. Linear and compound growth rates were calculated for this purpose. Ten growth models were fitted to the area, production and productivity of cotton crop and best- fitted model for future projection was chosen based upon least residual mean square (RMS) and significant Adj R2 besides, the important assumption of randomness of residuals was tested using one sample run test. The reference period of study was from 1979-80 to 2012-13 and it was carried out in three districts of Northern Telangana zone.Keywords

The diversity and abundance of Diptera at the Agri-biodiversity Park, Professor Jayashankar Telangana State Agricultural University, Hyderabad was studied from September 2019 to January 2020. Five collection methods (pitfall trap, yellow pan trap, manual collection, light trap and yellow sticky trap) were used and 6739 individuals under 27 families were collected. The results revealed that the most abundant family was Dolichopodidae (10.76%) followed by Sarcophagidae (10.19%) and Ceratopogonidae (8.92%). Yellow pan trap collected maximum number of individuals (2789), and revealed occurrence of maximum number of families (18). Shannon-Weiner diversity Index, Margalef’s species richness index and Pielou’s evenness index of the study area were 2.953, 2.949 and 0.896, respectively, indicating rich diversity of Diptera.Keywords
