Abstract:
The study was conducted in the Department of Biology - College of Education - University of Samarra, which aims to combat the third instar larvae of the date moth Ephestia cautella using bio-prepared zinc nanoparticles from the fungus Verticillium lecanii and comparing it with the biomass of the fungus Verticillium lecanii and finding out which is most effective in eliminating the third instar of the date moth Ephestia. cautella and biomass concentrations were used (1, 1.5, 2) g / L.
Only distilled water was used in the control plants, with a time period of (24, 48, 72) hours for each concentration, Three concentrations of zinc nanoparticles were used: (0.250, 0.125, 0.62) ml / liter , and only distilled water was used in the control laboratories, with a period of time of (24, 48, 72) hours for each concentration, and for each concentration, three replicates were used for each concentration, and 10 larvae of the date moth Ephestia cautella were placed in each replicate for each replicate of the experiment, and the results of each were given: Biomass had high killing results at a concentration of 2 ml/L after 72 hours, and nano zinc at a concentration of 0.250 ml/L after 72 hours.
