Abstract: A field experiment was conducted to study the bio-efficacy of some insecticides against mango hopper on mango at B.C.KV, Mohanpur, Nadia, West Bengal, India during 2016 and 2017. In present investigation, seven insecticides (including control) viz. Flonicamid 50%WG @ 15 g a.i. ha-1, Flonicamid 50%WG @ 20 g a.i. ha-1, Flonicamid 50%WG @ 25 g a.i. ha-1, Imidacloprid 17.8 % SL @ 25 g a.i. ha-1, Lambda cyhalothrin 5% EC @ 5 g a.i. ha-1 and Dimethoate 30%EC @ 50 g a.i. ha-1 were evaluated. Among all the treatments Flonicamid 50%WG @ 25 g a.i. ha-1 has found to be best treatment and recorded highest hopper mortality during the experiment. Highest mango yield of 74.4 Q/ha and 80.6 Q/ha were obtained in the treatment of Flonicamid 50% WG @ 25 g a.i. ha-1 dosage and the highest cost benefit ratio was also observed in the treatment Flonicamid 50% WG @ 25 g a.i. ha-1 in 2016 and 2017. All the doses of Flonicamid 50% WG were found safer to lacewings and spiders in mango ecosystem during the experiments.
