Summary: The mealybug Phenacoccus solenopsis is a polyphagous pest that poses a potential threat to plant health in the EU, mainly through imported fresh produce and plants for planting. It has been reported in Cyprus, Greece, and Italy, and phytosanitary measures are important in preventing further introductions and spread within the EU.

Summary: The cotton mealybug Phenacoccus solenopsis Tinsley (Hemiptera: Pseudococcidae) is an emerging invasive insect pest in China. Hymenopteran parasitoids have great potential to suppress populations of P. solenopsis and were investigated using a species delimitation approach. A total of 18 hymenopteran parasitoid species associated with P. solenopsis were identified, aiding in the potential use of these parasitoids in biological control programs.

Summary: The invasive mealybug on cotton, Phenacoccus solenopsis, is primarily controlled by conventional insecticides. However, these insecticides also have negative impacts on the potential biocontrol agent, Aenasius arizonenesis. The study found heterogeneity in the development of insecticide resistance and that profenofos, thiodicarb, and imidacloprid were hazardous, non-selective, and harmful to A. arizonenesis.

Summary: Microbial formulations from entomopathogenic fungi are emerging as effective alternatives to chemical pesticides in controlling crop pests. Among the five species tested in this study, higher doses of Metarhizium anisopliae, Beauveria bassiana, and Paecilomyces lilacinus were most effective in reducing the population of mealybugs on okra plants. Additionally, field trials showed higher doses of all biocontrol agents were more effective in controlling mealybug populations and increasing crop yield.

Summary: This study investigated the diversity of symbiotic microorganisms associated with the sap-sucking hemipteran insect, Phenacoccus solenopsis. The results showed significant differences in bacterial composition between female and male mealybugs, with Proteobacteria, Firmicutes, and Bacteroidetes being the dominant phyla in both sexes. The diverse assemblage of symbiotic bacteria in P. solenopsis may be critical in enabling this insect to utilize a wide range of host plants.

Summary: The cotton mealybug, Phenacoccus solenopsis, has different preferences for economic plants and weeds. The feeding behavior of the mealybug was studied on three exotic weeds of the Asteraceae family, and compared with cotton plants. The results showed that Artemisiifolia was the most suitable host for the mealybug, while B. pilosa and W. trilobata were less suitable. This study provides more evidence for the feeding harm of P. solenopsis and the role of exotic weeds as transfer hosts during uncultivated seasons.

Summary: Water scarcity is a major global challenge impacting food safety, food security, and human health. This study explored the potential of using vertical flow constructed wetlands (VF-CWs) with different indigenous wetland plants to treat chromium (Cr)-contaminated water. The results showed that VF-CWs vegetated with certain wetland plants can effectively remove Cr from water, with removal rates ranging from 47% to 92%. The wetland plants also accumulated Cr, with higher concentrations found in the roots. This research provides evidence supporting the use of VF-CWs with indigenous wetland plants as a sustainable technology for treating Cr-contaminated water.

Summary: The study determined the genetic characteristics of Bacillus thuringiensis Kurstaki (Btk) resistance in Earias vittella Fabricius, a potential pest for cotton and okra in South Asia. It was found that the resistance had autosomal, incompletely dominant, and polygenic nature. The study also showed that a high proportion of the resistance variation was heritable. These findings will support the development of effective resistance management plans to control E. vittella.

Summary: The performance of different macrophytes in floating treatment wetlands (FTWs) for the remediation of ciprofloxacin (CIP) contaminated water is investigated in this study. The FTWs have the potential to remove 30-43.58 mg L-1 CIP from water in 28 days, and also reduce the chemical oxygen demand and biochemical oxygen demand of water. Among the macrophytes, Canna indica is the most effective in removing CIP, while Typha domingensis is the least effective. This study contributes to the sustainable bioremediation of water contaminated with antibiotics.

Summary: This study investigated the distribution, speciation, hydrogeochemical behavior and environmental risks of chromium in tannery wastewater in Kasur district, Punjab, Pakistan. The concentration of chromium was higher in winter compared to summer, and exceeded the national environmental quality standard. The presence of chromium was mainly in the form of hexavalent and trivalent chromium, controlled by iron and magnesium minerals. Environmental risk assessment categorized the tannery wastewater as 'worst quality' and unsuitable for crop irrigation without treatment.

Summary: Antibiotic contamination in water is a global issue that poses severe health risks, but floating treatment wetlands (FTWs) show great potential for remediation. In this study, the use of FTWs with Fe3O4-NPs supported bacteria significantly enhanced the removal of Ciprofloxacin (CIP) and other pollutants from contaminated water. Fixing bacterial strains on iron oxide nanoparticles in FTWs proved to be an effective method for removing CIP and improving water quality.

Summary: The common house fly is a major carrier of diseases in humans and livestock and has developed resistance to many insecticides. This study found that alpha-cypermethrin resistance significantly increased in selected strains of common house flies compared to unselected strains. However, resistance to alpha-cypermethrin was unstable in field populations without exposure. The results of this study have implications for insect pest and vector management programs in Saudi Arabia.

Summary: This study investigated the susceptibility of Myzus persicae field populations to different insecticides and explored the metabolic mechanisms of resistance. The findings revealed varying levels of resistance to different insecticides, with moderate resistance to bifenthrin and acetamiprid, low-to-moderate resistance to fosthiazate, and low resistance to spirotetramat. However, the populations were susceptible to afidopyropen and flonicamid. Carboxylesterases and cytochrome P450 monooxygenases were found to be involved in the resistance, but glutathione S-transferases were not implicated. The study suggests the potential of flonicamid and afidopyropen as alternative insecticides for controlling M. persicae.

Summary: This study found that the house fly (Musca domestica L.) has developed resistance to the commonly used pyrethroid insecticide alpha-cypermethrin in Saudi Arabia. The resistance is due to the presence of metabolic enzymes such as glutathione S-transferases, specific esterases, and cytochrome P450 monooxygenases. The resistant strain of house fly exhibited lower fitness and decreased life history characteristics compared to the susceptible strain. These findings will contribute to the development of rational house fly control strategies.
