dc.description.abstractExperimentation for management of fruit fly on summer squash was conducted at Chatha farm, SKUAST-Jammu from March 2017 to June 2018 up to the harvest of the crop. In the present investigation, twelve types of lures with different combinations were studied for monitoring the fruit fly population. The studies revealed that, there was a significant difference recorded among all the twelve traps. In commercial traps, Green victory methyl eugenol (ME) fruit fly trap showed the best performance in capturing adult fruit fly population throughout the cropping period with catch of 479.33 fruit flies/trap. However, among innovative traps, low cost mineral bottle trap (ME + wooden block + spinosad) was found superior with 436.33 fruit flies/trap. The seasonal incidence of fruit fly observed at the experimental site indicated that fruit fly was found damaging and remained active on summer squash attaining peak value in the 26th SW(317 fruit flies/trap). The correlation studies showed that the fruit fly population was highly significant and positively correlated with mean relative humidity (morning and evening) and rainfall but highly negative correlation was found with maximum temperature. Among the six modules tested against fruit fly during 2018, module I was found to be superior and showed highest (87%) adult fruit fly mortality and least percent damage both on number basis (16.15%) and weight basis (11.69%). It was followed by module II having 17.15 per cent damage on number basis. However, in module III 23.40 per cent fruit damage was recorded on number basis followed by module IV with 28.35 per cent fruit damage. Among all the modules, the highest fruit damage on number basis was recorded in Module VI (60.19%). Thus the descending order of performance of modules were as follows: Module I > Module II > Module III > Module IV > Module V >Module VI. The perusal of the data during 2018 revealed that all modules were found to be cost effective but the highest yield and highest cost benefit ratio were obtained in case of module-I. The highest healthy fruit yield was also recorded in module I (350 q/ha) followed by Module II (320 q/ha). However, in module V (Farmer’s practices) yield of 160q/ha was recorded.The lowest yield was recorded in module VI (Control) i.e 80 q/ha. The module I gave highest benefit of Rs. 215550.00 followed by module II with benefit of Rs. 189268.00. The results also showed that the highest Cost Benefit ratio was obtained in case of Module I (1: 3.96) followed by module II (1:3.73) . The least C: B ratio was in module VI (1: 1.22).en_US
