Efficacy And Characterization Of Synthesized Zinc Oxide Nanoparticles Against Tribolium Castaneum And Trogoderma Granarium

Nano sciences and nanotechnology are the study of extremely small things at nm scale. The present studies were carried at Chemistry Laboratory, Punjab Bioenergy Institute, University of Agriculture Faisalabad. Different and mixed age Tribolium castaneum and Trogoderma granarium was collected from grain market which is located to be Faisalabad. The population for each of the two insect were acclimatized to the laboratory. To raise homogenous population, pupa of the same age were collected during in rearing of insect and in separate plastic jars for adult emergence (2 weeks). After extraction of plant materials, biosynthesis of nanoparticles was done accordingly to standard procedure. Toxicity Bioassays were done by three concentrations (5, 10 and 15 %) of the plant extracts (for each of the simple plant oils as well as nano-particles). Data according to mortality was recorded after 24, 48 and 72 hours of the treatment.Highest mortality (15.10%) and lowest (46.12%) was noticed against Tribolium castaeium. In case of nanoparticles data, 66.32% mortality was recorded by ZnO oxide particles against the Tribolium castanium and 49.51% against Trogoderma granarium. Repellency bioassay was done by area preference method. ZnO gave highest repellency 79.17. 77.56% ZnO highest replency was, against the Trogoderma granarium.Data of all the bioassays were analyzed by factorial under CRD statistical design.
