“…This proposes that purification of the extracts is important to enhance the larvicidal activity of compounds. This indicates that bioactivity guided fractionation and purification may lead to the isolation of active chemical compounds responsible for the larvicidal activity [43]. The fractions of P. stratiotes have low activity on Brine shrimp larvae.…”

Mosquito are well-known vectors that cause diseases particularly malaria and filariasis which are detrimental to human health. These vectors occur mainly in tropical countries where more than 2 billion people live in endemic regions with about one million deaths been claimed yearly from malaria and filariasis. The study is aimed at evaluating the larvicidal activity of Pistia stratiotes fractions on Anopheles mosquitoes (Diptera: Culicidae). The ethyl acetate extract of P. stratiotes was obtained through percolation process and was chromatographed to yield nine fractions. The larvicidal activity of each of the nine fractions was tested in triplicates by exposing the larvae to 500, 250, 125, 62.5 and 31.3 mg/ml, respectively. Phytochemical screening of the nine fractions revealed the presence of alkaloids, flavonoids, glycosides and phlobatannins in varying quantities. The result obtained shows that fraction E has the highest lethal effect on the Anopheles larvae at LC 50 ¼14.81 mg/ml and was weakly effective at 602.03 mg/ml on brine shrimp larvae. The gas chromatography mass spectrometry analysis of fraction E revealed the presence of 35 pre-cursor compounds. Hence, ethyl acetate fractions of P. stratiotes could be an effective larvicide against Anopheles mosquito larvae as it has been found to be harmless to other aquatic organisms. Further work should be done on other aquatic weeds that have larvicidal potential to isolate the bioactive compounds. ARTICLE HISTORY

Nanotechnology has acquired increasing interest recently in agriculture and crop production for achieving proficient utilization of resources by developing nanodelivery systems for agrochemical products or sensors (for nutrient status or water). The development of new nanofertilizers provides a promising opportunity to improve plant mineral nutrition. According to the reports, nanostructured materials are more efficient than traditional fertilizers, with a site-specific and controlled release of nutrients that not only increased the efficacy of plant uptake but also reduced negative environmental effects due to the loss of nutrients into the environmental matrices. In this section, we illustrate various kinds of novel nanostructured materials as promising carriers for nutrients such as nanoclays, carbon nanodots, carbon nanotubes, and nanofibers, hydroxyapatite nanoparticles, carbon-based nanomaterials, and polymeric nanoparticles. Also, the impact of nanomaterials on pesticides is discussed. They play a great contribution to enhancing agricultural productivity involving for gradual release and proper pesticide dosage to aid pest control. Different nanomaterials used are discussed contributing to the reduction of the exposure of humans to pesticides.

This work was a joint effort between the authors that is part of an ongoing collaboration aimed at providing scientific, medical, public health implications and evidence related to aerosolized coal fly ash including its use in the near-daily, near-global covert geoengineering activity. Author MW was primarily responsible for the entomological data. Author JMH was primary responsible for mineralogical and geophysical considerations. Both authors read and approved the final manuscript.
