Evaluation of dinotefuran 20 per cent SG against sucking pests of okra was undertaken in an experimental block at Agricultural Research Station, Bheemarayanagudi during Rabi 2012-13. The test chemical, dinotefuran 20% SG @ 30 g a.i. per ha is most effective dosage for the management of sucking pests like leafhopper, A. biguttula, aphids, A. gossypii, thrips, T. tabaci and whiteflies, B. tabaci and also recorded higher okra fruit yield of 93.01 q per ha. Apart from this, dinotefuran 20 per cent SG at varied dosages is quite safer to natural enemies. So, dinotefuran 20% SG @ 30 g a.i. per ha can be used for the effective management of sucking pests and for realizing higher okra fruit yield.Keywords

Studies related to species diversity and seasonal incidence of fruit flies in drumstick ecosystems were conducted at University of Horticultural Sciences (UHS), Udyanagiri, Bagalkot, India during Rabi 2015-16 and Kharif 2016. During Rabi 2015 Shannon Wiener index (H’) of diversity of the fruit fly population was maximum (H’=0.64) during 6th SMW of (February) 2016. The Pielou’s evenness (J’) value was maximum during 6th SMW of (February) 2016 and 52nd SMW of (December) 2015 (0.92 and 0.79, respectively). The maximum Simpson diversity index value (0.66) was recorded during 6th SMW of (February) 2016. During 2016 maximum H value (H’=0.61) was recorded during 38th followed by 36th SMW of (September) 2016 (0.79). The Pielou’s evenness (J’) ranged from 0.33 to 0.88. Maximum (J’) value was recorded during 38th SMW of (September) 2016 (0.88) and 36th SMW of (September) 2016 (0.79).Keywords
