Varietal/germplasm screening of Ber, Ziziphus mauritiana (Lamk) against Ber fruit fly, Carpomyia vesuviana (Costa) under semi-arid conditions of Haryana

Jayant Yadav, Ram Karan Gaur and Meenakshi Devi

The present study was carried out to screen various varieties/germplasms of ber, Ziziphus mauritiana (Lamk) against ber fruit fly, Carpomyia vesuviana (Costa) during 2016-17 at ber orchard of Chaudhary Charan Singh Haryana Agricultural University, Regional Research Station, Bawal. The study on varietal/germplasm screening revealed that there were marked differences in per cent fruit fly infestation on different varieties/germplasms. Kaithali exhibited maximum fruit fly infestation (51.06%) and BS- 1 showed minimum fruit fly infestation (1.51%). Out of total 39 varieties/germplasms, maximum no. of varieties/germplasms i.e. 14 fell in the category of susceptible (31.00 - 40.99% infestation). Two varieties BS-1 and Illaichi fell in the category of resistant (1.00-10.99% infestation). The data on fruit fly infestation showed that there is huge scope of utilizing host plant resistance as a pest management strategy and thus the ill effects of pesticides can be minimized.
