Mosquitoes still pose a clear risk to human and animal health. Recently, nanomaterials have been considered one of the cost-effective solutions to this problem. Therefore, alumina nanoparticles (Al) were synthesized using an auto-combustion method, followed by calcination at 600 and 800 °C. Glucose (G) and sucrose (Su) were used as fuels and the combustion was performed at pH 2, 7, and 10. The as-synthesized Al2O3 nanoparticles were characterized by XRD, FTIR, SEM, and TEM. Alumina nanoparticles prepared using G and Su fuels at pH 7 and 800 °C (Al-G7-800 and Al-Su7-800) have crystallite sizes of 3.9 and 4.05 nm, respectively. While the samples (Al-G7-600 and Al-Su7-600) synthesized at pH 7 and 600 °C were amorphous. The prepared alumina nanoparticles were applied to the larval and pupal stages of Culex pipiens. The results showed that alumina nanoparticles cause higher mortality in the 1st larval instar than in all other larval instars and pupal stages of Culex pipiens after treatment at a high concentration of 200 ppm. Additionally, the larval duration after treatment with LC50 concentrations of alumina (Al-G7-800 and Al-Su7-800) was 31.7 and 23.6 days, respectively, compared to the control (13.3 days). The recorded data found that the content of glutathione-S-transferase, alkaline/acid phosphatase, β/α-esterase, and total protein were altered upon treatment with the LC50 concentration of alumina (Al-G7-800) nanoparticles. Based on these findings, alumina nanoparticles are a promising candidate as a potential weapon to control pests and mosquitoes.

“… 27 The bioapplications based on magnetic NPs have gotten special attention because they have prominent advantages over other materials in terms of cost and ease of manufacture, physical and chemical stability, biocompatibility, and environmental safety, as well as the ability to be tuned and functionalized for specific applications. 28 Metal oxide NPs such as zinc oxide, 29 titanium dioxide, 30 silicon oxide, 31 , 32 iron oxides, 33 , 34 copper oxide, 35 and tungsten oxide 36 are also low-cost materials, easy to produce, and chemically stable. As a result, these nanomaterials are excellent candidates for various applications, including water treatment, 37 antimicrobials, 38 sensors, and many more.…”

Nanotechnology research is emerging as a cuttingedge technology, and nanocomposites have played a significant role in pest control. Therefore, the present study focuses on the synthesis of tungsten oxide (WO 3 ), iron oxide (magnetic nanoparticle, MNP), and copper-doped iron oxide (MNP-Cu) nanocomposites and explores the different effects of their binary combinations with the insecticide cyromazine against Spodoptera littoralis. The synthesized nanoparticles were characterized by transmission electron microscopy, X-ray diffraction, Fouriertransform infrared spectroscopy, and Raman spectroscopy. None of the tested nanomaterials showed any toxicity against the different stages of S. littoralis. Larval and pupal durations increased with increasing cyromazine and nanomaterial concentrations. The longest larval and pupal durations were recorded under treatment with the mixture of cyromazine (100 mg/L) + MNP-Cu (500 mg/ L); the survival periods were 23.5 and 15.6 days, compared with 10.8 and 7.7 days in the control, respectively. The percentages of pupation and adult emergence were negatively affected by all treatments. Among the 500 mg/L nanomaterial combinations, only cyromazine (25 mg/L) and WO 3 (500 mg/L) resulted in adult emergence (at a rate of 27.3%). Some abnormalities in the S. littoralis stages were observed following treatment with the tested materials. The glutathione S-transferase and alpha-esterase enzyme activities in S. littoralis were significantly increased after treatment with cyromazine, followed by cyromazine/MNP-Cu combinations. The quantitative polymerase chain reaction (Q-PCR) data showed that all treated insects had a higher immune response than the control. Finally, mixes of nanocomposites and cyromazine may be suggested as viable alternatives for S. littoralis management.

The objective of the study was to determine the species composition of mosquitoes and their associated insects and fungi inhabiting drain water in different agricultural areas of Assiut governorate, Egypt. During 72 inspection visits and 164 examinations of drain water pools in seven areas of Assiut governorate, results indicated the presence of six identified mosquito species. Culex pipiens is considered the most frequent mosquito species with the highest Incidence Area Weight value IAW21. All six identified mosquito species were encountered in El-Badary area with an Incidence Species Weight ISW value of 14.Nine insect species belonging to five orders were recorded. Pantala flavescens (Odonata: Libellulidae) is considered the most frequently associated insect species in all areas. Incidence Area Weight IAW for each identified species indicated that P. flavescens had the maximum value of IAW 14. Also, the maximum value of Incidence Species Weight was ISW 22 in El-Badary area.Twenty-four fungi species were identified from agricultural drain water pools. Aquatic fungi were twenty-two species inhabiting agricultural drain water and Nine fungi species were isolated from the associated insects. Some of these species recorded as entomopathogenic fungi for mosquitoes including Fusarium oxysporum, F. solani, and F. incarnatum. The incidence values of all fungi species isolated reached the maximum of 17 in Spring. So, the associated insect species and fungi with mosquitoes in the present study can play an active role as biological control agents in Integrated Pest Management (IPM) approach. This contributes to achieving the Sustainable Development Goals (SDGs).
