Abstract:

Studies related to species diversity and seasonal incidence of fruit flies in guava ecosystem was conducted at University of Horticultural Sciences (UHS), Udyanagiri, Bagalkot, India during 2015-16 and 2016-17. The species diversity indices of fruit flies during 2015-16 showed that Shannon index of diversity of the fruit fly population was maximum during 48th standard matereological week (SMW) of (November) 2015 (H’=1.06), followed by 27th SMW of (July) 2015 (H=’0.83). Maximum J' value was recorded (J'=0.98 and 0.96, respectively) during 40th and 51st SMW of 2015 and 1st, 3rd and 48th SMW 2016. The maximum Simpson diversity index value was recorded (0.84) during 1st SMW of (January) 2016. During 2016-17, Shannon index of diversity of the fruit fly population was maximum during 25th SMW of (June) 2017 (H’=1.08). Maximum J' value was recorded (0.98) during 25th SMW followed by 23rd SMW of (June) 2017 (0.95). The maximum Simpson diversity index value (0.84) was recorded during 23rd SMW of (June) 2017. When the total fruit flies were considered irrespective of the species, the first major peak population (80.25 flies per trap/week) was observed during 27th SMW of 2015 and during 29th SMW of (July) 2017 (71.50 fruit flies/trap/week).
