Characterization of Nanospheres Containing Zanthoxylum riedelianum Fruit Essential Oil and Their Insecticidal and Deterrent Activities against Bemisia tabaci (Hemiptera: Aleyrodidae)

Abstract: The aim of our study was to produce and characterize poly-ε-caprolactone (PCL) nanospheres containing essential oils from Zanthoxylum riedelianum fruit and to evaluate their stability gains as well as their insecticidal and deterrent activities against whitefly (Bemisia tabaci). The PCL nanospheres exhibited a homogeneous spherical morphology, with particle diameters between 106.7 nm and 129.2 nm, pH of approximately 6, zeta potential (ZP) lower than −19.0 mV and encapsulation efficiency higher than 98%.

“…146 More examples of herbal loaded NE are presented in Table 1. 142,143,[147][148][149] Nanocrystals They are pure drug crystals with nanosized particles (Figure 9) in which toxic side effects resulting from the encapsulating/solubilizing excipients may be eliminated. 150 The best known features of nanocrystals are high drug-loading capacity and platform stability that render them to be widely used to deliver poorly hydrophilic materials in the form of a colloidal dispersion.…”

“…Polymers like poly (lactide) (PLA), poly-ε caprolactone (PCL) and poly lactide-co-glycolide (PLGA) are the most commonly used substances for nanoprecipitation (Rosset et al, 2012). Nanoencapsulation of Zanthoxylum riedelianum EO through nanoprecipitation caused improvement in the insecticidal activity against whitefly (Bemisia tabaci) and reduction in its photo-degradation up to 33% (Pereira et al, 2018). Besides, being the fast and economic technique, it is best suited for encapsulating hydrophobic substance (EOs) in comparison to hydrophilic core material (Ladj-Minost, 2012).…”
