Impact of nanoformulations on Bagrada bug, Bagrada hilaris (Burmeister) (Pentatomidae: Heteroptera) in Indian mustard under controlled condition

Laboratory experiments were conducted in order to find out the impact of nanoformulations on a painted bug, Bagrada hilaris at Department of Plant Protection, Aligarh Muslim University, UP during 2014-2016. The main objective was to study the effect of nanoformulations of NSKE, copper, silver and manganese in comparison with conventional chemicals like imidacloprid and Neemazal as a recommended insecticide on the mustard crop. Mustard pods and young branches were treated with six different concentrations 1:10, 1:100, 1:200, 1:500, 1:1000 and 1:2000 of the tested compounds. Fifteen individuals of painted bugs were released to each petriplate and the observations on mortality of insects were taken after 24 hrs, 48 hrs and 72 hrs of treatments in comparison with untreated control. Results showed that imidacloprid was most toxic than other tested compounds and documented the least LC50values (0.002) and within the nano formulations silver was found to be superior LC50 (0.004) followed by copper, manganese, NSKE with LC50 of 0.011, 0.032, 0.045 respectively. Whereas neemazal was found to be least effective and showed highest LC50 (0.124). The highest per cent mortality was found in the population treated with imidacloprid as (97.78±0.71) % over control (2.37±1.01) % at 1:10 concentration. Among all nanochemicals, per cent mortality was recorded maximum (84.44±0.58) in the population treated with silver at 1:10 concentration on the 4th day of application followed by copper (77.78±0.58), manganese (73.33±1.00) and NSKE (68.89±1.53).
