Abstract：
Recently, nanoparticles have been widely used in agricultural pest control as a secure substitute for pesticides. However, the effect of nanoparticles on controlling the subterranean termite Odontotermes formosanus (O. formosanus) has not been studied yet. Consequently, this study aimed to evaluate the effectiveness of some nanomaterials in controlling O. formosanus. The results showed that zinc oxide nanoparticles (ZnONPs), titanium dioxide nanoparticles (TiO2NPs), and chitosan nanoparticles (CsNPs) biosynthesized using the culture filtrate of Scedosporium apiospermum (S. apiospermum) had an effective role in controlling O. formosanus. Moreover, the mortality rate of O. formosanus after 48 h of treatment with ZnONPs, TiO2NPs, and CsNPs at a 1000 µg/mL concentration was 100%, 100%, and 97.67%, respectively. Furthermore, using ZnONPs, TiO2NPs, and CsNPs on O. formosanus resulted in morpho-histological variations in the normal structure, leading to its death. X-ray diffraction, UV-vis spectroscopy, Fourier transform infrared spectroscopy, scanning electron microscopy, dynamic light scattering, energy dispersive spectroscopy, and the Zeta potential were used to characterize the biosynthesis of ZnONPs, TiO2NPs, and CsNPs with strong activity against O. formosanus termites. Overall, the results of this investigation suggest that biosynthesized ZnONPs, TiO2NPs, and CsNPs have enormous potential for use as innovative, ecologically safe pesticides for O. formosanus control.
摘要：
最近,作为一种安全的农药替代品,纳米粒子已广泛应用于农业害虫防治。然而,纳米颗粒对控制地下白蚁Odontotermesformosanus（O。formosanus)尚未研究。因此,本研究旨在评估一些纳米材料在控制O.formosanus中的有效性。结果表明,纳米氧化锌(ZnONPs),二氧化钛纳米颗粒(TiO2NPs),和壳聚糖纳米颗粒（CsNPs）生物合成的培养滤液cedosporiumcapiospermum（S.apiospermum）在控制Formosanus方面具有有效作用。此外，用ZnONPs治疗48小时后，Formosanus的死亡率，TiO2NPs,和CsNP在1000μg/mL浓度为100%，100%,和97.67%，分别。此外，使用ZnONPs，TiO2NPs,和CsNPs在O.Formosanus上导致正常结构的形态组织学变化，导致它的死亡。X射线衍射,紫外-可见光谱，傅里叶变换红外光谱,扫描电子显微镜，动态光散射,能量色散光谱，Zeta电位用于表征ZnONPs的生物合成，TiO2NPs,和CsNP对O.Formosanus白蚁具有很强的活性。总的来说,这项研究的结果表明，生物合成的ZnONPs，TiO2NPs,CsNP具有巨大的创新潜力，用于O.Formosanus控制的生态安全农药。
