valuation The efficiency of Nanotechnology and biological activity of Nanoparticle for two plant extracts Ricinus communis and Neriun oleander against immature stages of Greater wax moth.Galleria mellonella (Lepidoptera: pyralidae)

The results of present study conducted on the Laboratory advance entomology \ Department biology Faculty Education for Girls University Kufa, during years 2018-2019 evaluating efficiency Nanotechnology and biological control effect two plant extracts different immature stages greater wax moth Galleria mellonella (Lepidoptera: Pyrallidae). eggs, first fourth larval instars. cold aqueous extract castor Ricinus communis Nerium oleander leaves ,from which concentrations ( 1,2,3 4) mg ml were prepared in Laboratory. experiments include enhancement these toxic nature with chemically particles, silver nanoparticles, conducting multiple same instars insect, was treated .The statistical as well observation superior nanoextracts over mortality eggs latval Experiments indicated that percentages when (76, 91, 96) % respectively while nano was(83.3 ,92.3 ,98.6 )% respectivly . N.oleander (86.6%, 96.6%, 99.4%) compared (93.3, 100, 100) nanoparticle larvae phases at 4 / ml. It also proved instar most sensitive to instar, where highest (96.6, (86.6, 93.3)% N. R.communis respectively.
