Abstract

The present investigation on "Studies on species composition and host range of different scarabaeid adults under rainfed situations of Belagavi district" was carried out during kharif 2014-15 at Chikkodi (Hattarwata) and Hukkeri (Akkiwata) taluks of Belagavi district. Irrespective of the different locations the faunistic study of different scarabaeid adults occurring in the groundnut growing tracts of Belagavi district revealed that Holotrichia fissa Brenske is most dominant species associated with groundnut. Irrespective of the occurrence of different species Ziziphus mauritiana Lam. attracted more numbers of adults. Holotrichia fissa Brenske was found to show the higher preference to ber (Z. mauritiana) followed by other hosts like Lannea coromandelica (Hautt.) Merill. in all the locations. While Bauhinia racemosa Lam. and Ziziphus horrida Roth. are recorded as new hosts for H. fissa. On the contrary, Holotrichia serrata (Fabricius) showed a definite preference for neem.
