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