“…There has been a steady increase in published studies concerning the encapsulation of essential oils and/or their constituents in matrices including natural or synthetic polymers, lipids, and proteins, among others, according to the desired characteristics (Chen et al, 2009(Chen et al, , 2015de Oliveira et al, 2014;Gabriel Paulraj et al, 2017;Guimarães et al, 2015;Keawchaoon and Yoksan, 2011;Negahban et al, 2007Negahban et al, , 2012Negahban et al, , 2014Yang et al, 2009). However, it should be noted that most of these studies have focused on the development of methods for the encapsulation of these compounds for food and pharmaceutical purposes (Pavela and Benelli, 2016;Rodríguez et al, 2016).…”

Recent decades have witnessed major growth in the use of agrochemicals worldwide,for maximizing the food production for a rapidly growing human population. However, the indiscriminate use of these substances especially the pesticides has led to the accumulation of toxic residues in food, soil, air, and water, as well as the development of resistance in pests. Moreover, pesticides affect soil enzymes, which are essential catalysts that govern soil quality. In order to meet the food security, it is necessary to produce more food, sustainably and safely, in a diminishing area of available arable land and with decreased water resources. Given this situation, there is an increased interest in the use of alternative substances to synthetic agrochemicals that present less risk to the environment and human health while increasing the food safety. Promising results have been obtained using compounds derived from aromatic plants for the control of agricultural pests. Such compounds of botanical origin can be highly effective, with multiple mechanisms of action, while at the same time having low toxicity towards nontarget organisms. However, the large-scale application of these substances for pest control is limited by their poor stability and other technological issues. In this backdrop, the present work discusses perspectives for the use of compounds of botanical origin, as well as strategies employing the encapsulation techniques that can contribute to the development of systems for use in sustainable agricultural practices.

Background The use of synthetic insecticides is one of the most common strategies for controlling disease vectors such as mosquitos. However, their overuse can result in serious risks to human health, to the environment, as well as to the selection of insecticidal resistant insect strains. The development of efficient and eco-friendly insect control is urgent, and essential oils have been presented as potential alternatives to synthetic insecticides. Moreover, nanoencapsulation techniques can enhance their efficiency by protecting from degradation and providing a controlled release rate. Results We assessed the potential of chitosan nanoparticles in encapsulating Siparuna guianensis essential oil, and maintaining its efficiency and prolonging its activity for the control of Aedes aegypti larvae. The encapsulation was characterized by scanning electron microscopy (SEM), Fourier-transform infrared spectroscopy (FTIR), and thermogravimetric analysis (TGA), with an encapsulation efficiency ranging from 84.8% to 88.0%. Toxicity studies have demonstrated efficacy against mosquito larvae over 50% for 19 days with 100% mortality during the first week. This persistent action is presumably due to the enhanced contact and slow and maintained release conferred by chitosan nanoparticles. Furthermore, the exposure of aquatic non-target organisms (e.g. embryos and small adult fishes) revealed adequate selectivity of these nanoparticles. Conclusions The encapsulation of S . guianensis essential oil in chitosan nanoparticles showed promising potential as a larvicide control alternative and should be considered within strategies for fighting Ae . aegypti .

Biopesticides are very important alternatives to the synthetic pesticides and several botanicals have been reported as pesticides, antifeedants, insect growth regulators and repellents [3]. Biopesticides offer a more sustainable solution to pest control than synthetic alternatives.…”

Abstract. Nanotechnology plays an important role in providing opportunities and possibilities for the development of a plant extracts, particularly applied for agriculture using the organic nanoparticles extract as bioinsecticide. This paper reports the extraction of L. camaraas an insecticidal compound applied to control the S. litura larvae which is the main pest for agricultural commodities in Indonesia. The objective of this research is to evaluate the toxicity performance of nano extract to S. litura larvae. The extract was prepared by maceration and evaporation and followed by particles stabilization. The received suspension was characterized using a Particles Size Analyzer (PSA). The performance evaluation was conducted using dye feed method by observing at 24 h and 48 h. The toxicity performance of L. camara nano extract on S. litura larvae was evaluated based on the lethal concentration which was obtained at 50% of 3 rd instar larvae S. litura (LC 50 ) and the toxicity level. The larval mortality data was analyzed by probit analysis to obtain LC 50 values. The results showed that the LC 50 value of L. camara nano extract after 24 h was 16,347 ppm and after 48 h the LC 50 value was 3,548 ppm. The smaller LC 50 values indicate a stronger toxicity level, in contrast the best toxicity was LC 50 after 48 h with the concentration of 3,548 ppm. Referring to toxicity category standard with LC 50 pesticide value, the range 0.5-5 g/L is considered as medium toxic category. Toxicity level of L. camara nano extract to S. litura 3,548 ppm or 3,548 mg/L is considered as medium toxic category.
