“…These preparations in a study demonstrated significant reduction in Tuta absoluta , a tomato leafminer. They presented no significant difference in their insecticidal efficacy when compared with a chemical pesticide, imidacloprid (El-Samahy et al, 2014 ). In another study, nanoemulsions of neem oil extracted from the seeds of the plant was developed in order to retard the high degradability of neem based biopesticides.…”

Over the years, extensive use of commercially available synthetic pesticides against phytophagous insects has led to their bioaccumulation in the environment causing increased resistance and reduction in soil biodiversity. Further, 90% of the applied pesticides enter the various environmental resources as a result of run-off, exposing the farmers as well as consumers of the agricultural produce to severe health issues. Therefore, growing attention has been given toward the development of alternate environmentally friendly pesticides/insecticides that would aid an efficient pest management system and also prevent chronic exposures leading to diseases. One such strategy is, the use of neem plant's (Binomial name: Azadirachta indica) active ingredients which exhibit agro-medicinal properties conferring insecticidal as well as immunomodulatory and anti-cancer properties. The most prominent constituent of neem is azadirachtin, which has been established as a pivotal insecticidal ingredient. It acts as an antifeedant, repellent, and repugnant agent and induces sterility in insects by preventing oviposition and interrupting sperm production in males. This review discusses, key neem pesticidal components, their active functional ingredients along with recent strategies on employing nanocarriers, to provide controlled release of the active ingredients and to improve their stability and sustainability.

“…Nanoparticles represent a new generation of environmental remediation technologies that could provide cost-effective solution to some of the most challenging environmental clean-up problems (Chinnamuthu and Boopathi, 2009). Silica nanoparticles (SNPs) have been evaluated against the cotton leafworm Spodoptera littoralis (El-bendary and El-Helaly, 2013), the tomato borer Tuta absoluta, the stored grain insect-pest [the rice moth] Corcyra cephalonica (Vani and Brindhaa, 2013), the pink bollworm Pectinophora gossypiella (Derbalah et al, 2014) and the lesser grain borer beetle Rhyzopertha dominica and the red flour beetle Tribolium castaneum (El-Samahy et al, 2014). The treatment of hydrophobic silica nanoparticles (SNPs) with the pulse seeds against the infestation of stored pulse beetle,…”

“…It caused a decrease in larval survival by 40% mortality at a minimum concentration of 15 mg. After 6 days of exposure, this mortality increased to 56.7, 86.7, and 96.7% at concentrations of 30, 60, and 90 mg, respectively (Table 2). The toxicity of MSNs was recorded previously against various insects (Mesbah et al 2017;Arumugam et al 2016;Ziaee and Ganji 2016; El-Samahy et al 2014;Vani and Brindhaa 2013;Barik et al 2012;Galal and El-samahy 2012;Rouhani et al 2012 andDebnath et al 2011).…”

Cinnamon (Cinnamomum zeylanicum Blume) essential oil has vast potential as an antimicrobial but is limited by its volatility and rapid degradation. To decrease its volatility and prolong the efficacy of the biocide, cinnamon essential oil was encapsulated into mesoporous silica nanoparticles (MSNs). The characterization of MSNs and cinnamon oil encapsulated with silica nanoparticles (CESNs) was estimated. Additionally, their insecticidal activity against the rice moth Corcyra cephalonica (Stainton) larvae was evaluated. The MSN surface area decreased from 893.6 to 720 m2 g−1 and the pore volume also decreased from 0.824 to 0.7275 cc/g after loading with cinnamon oil. X-ray diffraction, Fourier transform infrared spectroscopy (FTIR), energy-dispersive X-ray spectroscopy (EDX), and N2 sorption by Brunauer–Emmett–Teller (BET) confirmed the successful formation and evolution of the synthesized MSNs and CESN structures. The surface characteristics of MSNs and CESNs were analyzed by scanning and transmission electron microscopy. Compared with the sub-lethal activity values, the order of toxicity after 6 days of exposure was MSNs ˃ CESN ˃ cinnamon oil ˃ silica gel ˃ peppermint oil. The efficacy of CESNs gradually increases its toxicity more than MSN after the 9th day of exposure.
