Abstract: Micro sciences including nanotechnology are nm-scale investigations of extremely small objects. Specific and mixed age Tribolium castaneum and Trogoderma granarium have been reported from Faisalabads grain market. The population had been acclimatized to the laboratory for each of the two species. Pupa of same age were obtained during insect rearing and in separately plastic containers for adult development (2 weeks) to increase diverse population. After isolation of plant products, biosynthesis of microparticles was performed similarly to standard operating procedure
