An experiment was conducted on safety studies on certain pesticides and biopesticides against Green lacewing, Chrysoperla zastrowi sillemi (Esben- Peterson) under laboratory conditions, which were carried out at Agricultural Entomology Laboratory at Vanavarayar Institute of Agriculture, Pollachi during December 2018 – March 2019. The data on per cent mortality of third instar grubs due to effect of pesticides and biopesticides shows that the treatment Bacillus thuringiensis 0.025%recorded 0 per cent grub mortality of third instar grubs and emerged as the best treatment. Next superior treatments in order of safeness were Pseudomonas fluorescens 0.5%, Nomuraea rileyi 0.5%,Abamectin 1.9 EC, Metarrhizium anisopliae 0.5%, Lecanicillium lecanii 0.5%,NSKE 5%, Thumbai leaf extract 5%, Neem-Azal 1%, Pungam oil 3%, Beauveria bassiana 0.5%,Novaluron 10 EC, Tobacco leaf extract 5%, Imidacloprid 17.8 SL, 3G mixture 5%, Thiamethoxam 25 WG, Lambda cyhalothrin 5 EC which recorded 8.9, 13.7, 16.6, 17.0, 18.4, 22.1, 23.4, 25.0, 31.3, 40.8, 44.2, 49.8, 78.9, 88.7 per cent mortality, respectively. Acephate 75% SP was the most toxic to the third instar grubs, which recorded 100 per cent grub mortality.
