Abstract:
The study was conducted with the aim of furthering our understanding influence of abiotic factors on relative abundance and infestation rates of the fruit flies in ridge gourd during kharif season of 2018 and kharif 2019 at Post Graduate Research Farm, Department of Agricultural Entomology, MPKV, Rahuri, Dist. Ahmednagar. The data on kharif season of 2018, the catch number of adults fruit flies ranged between 31.77 to 98.33 per trap per week. The activity of fruit flies reaching the peak of 98.33 fruit flies/trap/week during 1^st week of September (36^th standard week). During cropping season, the infestation varied from 15.18 to 56.98 per cent on number basis. Minimum per cent fruit damage (15.18) was recorded in 2^nd week of October (41^st SMW), while maximum (56.98) during 1^st week September (36^th SMW). In kharif 2019 number of fruit fly adults ranged between 18.67 to 83.33 per trap per week. Minimum per cent fruit damage (7.33) was recorded in 1^st week of August (31^st SMW), while maximum (56.12) during 1^st week of September (35^th SMW). The data on correlation between fruit flies with different meteorological parameters showed that the various meteorological parameters were found to be non-significant except minimum temperature.
