Experiments were carried out under laboratory condition to assess the toxicity of nano emulsion of hexanal on egg and grub stage of green lacewing, Chrysoperla zasrowi sillemi Stephens (Chrysopidae: Neuroptera) through laboratory bioassay. The results showed that, nanoemulsion of hexanal was found to cause egg hatchability up to 88.50 percent in higher concentrations of 0.06 percent. Egg hatchability at field recommended concentration of 0.02% was found maximum of 91.44 percent respectively. In addition nano emulsion of hexanal at field recommended concentration 0.02% tested against grubs of C. zastrowi sillemi results revealed that zero percent grub mortality in poison food technique and 6.25 percent in diet contamination method at 48 and 24 h after exposure it was least toxic to grub of C. zastrowi sillemi. The maximum percent pupation and adult emergence was recorded in nanoemulsion of hexanal @ 0.02% showed 90 and 100 percent, respectively. In addition the effect of nanoemulsion of hexanal on biological parameters of C. zastrowi sillemi showed that 14.80 days adult longevity and 323 egg are laid by five female. The results clearly indicated that all the concentration of nano formulation of hexanal was harmless to C. zastrowi sillemi which recorded a mortality of < 30 percent as per the threshold prescribed by IOBC.
