Comparative analysis of the insecticidal activity of Biogenic Zinc Oxide Nanoparticles, Iron Oxide Nanoparticles and piper nigrum fruits extract against 1st instar larva of House fly, (Musca domestica) (Diptera: Muscidae)

The housefly (Musca domestica) is a common and important medical insect that can transfer more than a hundred of pathogens. Thus, there is a crucial need for effective strategies with biocompatibility properties to be considered in eliminating the widespread of this insect. Green-manufactured Zinc oxide nanoparticles (ZnONPs) and iron oxide nanoparticles (α-Fe2O3NPs) have been highlighted as biocompatible and eco-friendly choices to counteract the threat of insecticidal-resistant insects. Thus, the current study evaluates their potential by investigating their activity against 1st-instar larvae of houseflies. ZnONPs and α-Fe2O3NPs were synthesised using Piper nigrum fruit extract as a reducing and capping agent. The nanoparticles were characterised using an ultraviolet-visible spectrophotometer, Fourier-transform infrared spectroscopy, X-ray diffraction, and scanning electron microscope measurements. The study explored the impacts of various concentrations of ZnONPs and α-Fe2O3NPs using a feeding assay of 1st-instar larvae and investigated the mortality and morphological changes in larvae, pupae, and emerging adults. Biogenic nanoparticles had a sub-spherical shape with a size of 20-30 and 30-40 nm for ZnONPs and α-Fe2O3NPs, respectively. The nanoparticles have caused obvious morphological abnormalities in the larvae, pupae, and adult emerging. LC50 values of ZnONPs, α-Fe2O3NPs and Piper nigrum fruit extract were 2, 1.2 and 75 mg/g, respectively. ZnONPs and α-Fe2O3NPs may accord to reducing the attempts, risk indications, and economic amounts raised from applying chemical insecticides. Thus, insect administration using nanoparticles could unfold deep advanced sides.
