| Conteúdo: | Abstract: Huanglonbing, or citrus greening, is the most serious disease of citrus which cause large economic losses. One of the strategies to avoid the spread of the disease is the control of Diaphorina citri psyllid, its insect vector, by the application of insecticides. Development of nanoinsecticides, which are less harmful to the environment and more efficient (in terms of cost and performance) than the existing formulations, is a current challenge. In this work, nanocarriers composed of chitosan–tripolyphosphate (by ionic gelification approach) and poly-ε-caprolactone (PCL)–chitosan (by double-emulsion–solvent evaporation method) for thiametoxam insecticide were developed and characterized. Toxicological assessments using Raphidocelis subcapta, Artemia salina and Caernohabditis elegans were performed comparing PCL–chitosan nanoparticle and PCL–chitosan loaded thiamethoxam in comparison to commercial pesticide. The nanoparticles obtained from optimized conditions resulted in positive charged nanoparticles, with medium dispersity. The double-emulsion method resulted in smaller nanoparticles (313.5 ± 7 nm) and increased encapsulation efficiency (36.6 ± 0.2%) in comparison to chitosan–tripolyphosphate nanoparticles. The lower encapsulation efficiency was observed in chitosan–tripolyphosphate, impairing agricultural applications. The EC50 values (mg L−1) of Raphidocelis subcapitata and C. elegans obtained for poly-ε-caprolactone with thiamethoxam were 56.15 (18.91–131.21) and 66.07 (1.20–274.14), respectively, and poly-ε-caprolactone without thiamethoxam 94.26 (22.42–166.10) and 214.63 (139.08–494.3), respectively. No toxicity was found in Artemia salina. Our results indicate that nanoparticles (with and without thiamethoxam) were more toxic to soil organisms (C. elegan) than commercial formulations. |

| Conteúdo: | Bisphenol A and ethinylestradiol, both considered as endocrine disruptors, have been found in surface water and effluents from municipal wastewater supply and can cause adverse health effects on wildlife species and in human beings at extremely low level. In order to remove these compounds from wastewater, constructed wetlands has been used since it proved to be more efficient, and has less cost than conventional treatments. One of the mechanisms of removal of endocrine disruptors by constructed wetlands is the uptake by macrophytes, so it is necessary to analyze these compounds in the plants of the system. Thus, the objective of this study was to develop and validate two methods by high performance liquid chromatography with fluorescence detector capable of determining these compounds in dwarf papyrus and water hyacinth. The evaluated parameters in the validation were: linearity (R2≥ 0.99), limit of detection (LOD = 0.045-0.15 μg g-1), limit of quantification (LOQ = 0.15-1.50 μg g-1), accuracy (recoveries from 83.5 to 119.4%) and precision (intra-day CV ≤ 6.2% and inter-day CV ≤ 5.8%). Samples from a constructed wetland were analyzed and the developed methods showed be suitable for intended purpose. |

| Conteúdo: | Abstract: The sterile insect technique (SIT) has been widely used to suppress several fruit fly species. In southern Brazil, millions of sterile flies of the South American fruit fly, Anastrepha fraterculus Wiedemann (Dipetra: Tephritidae), will be produced in a massrearing facility called MOSCASUL to suppress wild populations from commercial apple orchards. In spite of standard rearing conditions, the quality of pupal batches can be inconsistent due to various factors. The quantification of poor quality material (e.g. empty pupae, dead pupae or larvae) is necessary to track down rearing issues, and pupal samples must be taken randomly and evaluated individually. To speed up the inspection of pupal samples by replacing the manual testing with the mechanized one, this study assessed a multispectral imaging (MSI) system to distinguish the variations in quality of A. fraterculus pupae and to quantify the variations based on reflectance patterns. Image acquisition and analyses were performed by the VideometerLab4 system on 7-d-old pupae by using 19 wavelengths ranging from 375 to 970 nm. The image representing the near infrared wavelength of 880 nm clearly distinguished among high-quality pupae and the other four classes (i.e. low-quality pupae, empty pupae, dead pupae and larvae). The blind validation test indicated that the MSI system can classify the fruit fly pupae with high accuracy. Therefore, MSIbased classification of A. fraterculus pupae can be used for future pupal quality assessments of fruit flies in mass-rearing facilities. |
