Abstract/Description: | AbstractHost plant resistance is an important component for management of the melon fruit fly, Bactrocera cucurbitae (Coquillett) owing to difficulties associated with its chemical and biological control. The 43 snapmelon genotypes were taken for screening against B. cucurbitae and significant differences were found in percentage fruit infestation and larval density per fruit. Pooled data showed that the snapmelon genotypes IC-430176, DKS-AHS 2011/4, IC-430190 and DKS-AHS 2011/3 had fruit infestation (18.63%, 14.46%, 10.79% and 18.19%, respectively) and larval population per plant (8.80, 8.73, 8.32 and 8.67, respectively) and declared as resistant genotypes to fruit fly. The genotypes IC-430154, IC-430155, IC-430156, IC-430157, IC-430158, IC-430159, IC-430161, IC-430164, IC-430168, IC-430169, IC-430170, IC-430171, IC-430172, IC-430177, IC-430178, IC-430182, IC-430183, IC-430184, IC-430186, IC-430187 and DKS-AHS 2011/1 were categorized as susceptible genotypes, whereas, the genotypes IC-430160, IC-430162, IC-430163, IC-430165, IC-430166, IC-430167, IC-430173, IC-430174, IC-430175, IC-430179, IC-430180, IC-430181, IC-430185, IC-430188, IC-430189, IC-369788, DKS-AHS 2011/2 and DKS-AHS 2011/5 were moderately resistance genotypes to fruit fly in pooled data of both the seasons viz., 2014 and 2015. Lower values of host plant susceptibility indices based on fruit infestation (HPSI) were recorded on genotypes IC-430176, DKS-AHS 2011/4, IC-430190 and DKS-AHS 2011/3 (39.35%, 30.54%, 22.79 and 38.42%, respectively) could be used as a source of resistance for developing snapmelon genotypes resistant to fruit fly. |
