Abstract: A comprehensive study was carried out on mass rearing of Green Lacewing, Chrysoperla carnea (Stephen) (Chrysopidae: Neuroptera) with the objective to rear the cannibalistic larvae in a simplest and economical way and to wipeout the use of anesthesia (carbon dioxide), vacuum sucker in adult handling and other problems viz. cleaning and sanitation of adult rearing cage, ventilation and illumination in the cage, use of chemical for harvesting of eggs on black organdy and diapause phenomena of adults due to humidity below 35 percent. The difficulties in field releases of the voracious predator viz. reduced viability of eggs during chemical harvesting, ill defined field applications and high perdition of stalk less eggs in the field were also target of the research studied.
