abstract
An experiment was carried out to evaluate the resistance of different okra varieties against cotton jassid at Entomology Section of Rice Research Institute, Dokri, Larkana, during kharif season 2015. The highest infestation of jassid was observed in last week of May on Arizona (18.00) per plant followed by Super green (17.00), Sabzpari (16.66) and Reham (14.33). Similarly minimum infestation of jassid was observed in initial week of May on Sabzpari variety (2.00) followed by Super green (2.00), Arizona (2.33) and Resham (2.66). The data further showed the overall mean population of jassid on okra varieties i.e. Arizona (7.12 ± 5.22) followed by Super green (6.96 ± 4.30), Resham (6.42 ± 4.40) and Sabzpari (6.22 ± 4.93). It is concluded from the data that jassid population was significantly (P<0.05) affected by different dates, whereas non-significantly (P>0.05) by varieties and their interaction. Maximum jassid population was recorded on 29-05-2015, whereas minimum jassid population was observed on 19-06-2015. Jassid population was noted in variety Arizona while minimum population was recorded in variety Sabzpari.
