Abstract
Abstract : The present investigation on “Bio-efficacy of some newer insecticides against sucking pests of pomegranate” was conducted during Ambia bahar 2020-21 on the field of Entomology (H-24) at National Research Centre on Pomegranate, Solapur.
The studies on seasonal incidence of sucking pests on pomegranate during Ambia bahar 2021 from 1st SMW to 18th SMW revealed that maximum incidence of aphids (16.45 aphids/10 cm shoot) was observed in 4th SMW whereas, aphid population correlated negatively significant with maximum temperature (r= -0.873), minimum temperature (r= -0.840) and evaporation (r= -0.828). However, the maximum incidence of thrips (13.38 thrips/10 cm shoot) was observed in 5th SMW whereas, thrips population correlated non-significant with sunshine (r= -101) and rainfall (r= -0.316). In case of natural enemies, the maximum occurrence of coccinellids (3.80/ 10 cm shoot) at 4th SMW and chrysopids (3.42 chrysopids/10 cm shoot) at 5th SMW were recorded.
Studies on bio-efficacy of some newer insecticides against sucking pests of pomegranate revealed that the treatment with Flonicamid 50 WG @ 1 g/L was found more effective against pomegranate aphid population followed by Cyantraniliprole 10.26 % OD @ 1 ml/L and Tolfenpyrad 15 % EC @ 1 ml/L. However, for the control of thrips treatment with Spinetoram 11.7% SC @ 1 ml/L found most effective treatment and followed by Flonicamid 50 WG @ 1 g/L Cyantraniliprole 10.26 % OD @ 1 ml/L. As regard the safety of insecticide to natural enemies, the treatment comprised of Cyantraniliprole 10.26 % OD @ 1 ml/L, Spinetoram 11.7% SC @ 1 ml/L were relatively safer to natural enemies i.e. coccinellids and chrysopids.

Description : The present investigation entitled “Bio-efficacy of some newer insecticides against sucking pests of pomegranate” was carried out at ICAR- NRCP, Solapur during 2020-21. The treatment comprised of insecticide, Cyantraniliprole 10.26% OD, Tolfenpyrad 15% EC, Afidopyropen 50 DC, Flonicamid 50 WG, Emamectin Benzoate 3% + Thiamethoxam12% WG, Diafenthiuron 40.1%+ Acetamiprid 3.9% WP, Spinetoram 11.7% EC and Control (water) which were executed in randomized block design with three replications.
