Summary: A new EF fumigation technique with N-2 carrier was developed and evaluated for its efficacy against citrus mealybugs and phytotoxicity on banana fruit. The concurrent treatment of EF and N-2 showed effective control of mealybugs and the addition of PH3 enhanced the efficacy. The results suggest the potential application of EF and N-2 treatment for mealybug control.

Summary: Hibiscus mealybug is an emerging and serious pest of citrus in Florida, with measures such as sanitizing personnel and equipment helping to limit its spread. Isopropanol sprays can effectively incapacitate the majority of mealybug crawlers but are not effective against ovisacs. Steam treatments and hot water immersion can reliably lead to 100% mortality of ovisacs, but longer times and higher temperatures are needed for steam treatments if ovisacs are insulated by equipment.

Summary: The cotton mealybug Phenacoccus solenopsis is a highly invasive and harmful pest causing significant damage to cotton crops in multiple countries. Insecticidal control is currently the main method, but resistance to insecticides is increasing, making biocontrol agents a promising alternative for effective management.

Summary: This study assessed the potential of Planoccocus citri and P. solenopsis as prey for mass-rearing Orius laevigatus. The results showed that eggs of Ephestia kuehniella were the most suitable prey for mass-rearing. Although P. solenopsis had worse results than E. kuehniella, it still showed potential.

Summary: This study quantified the life-history parameters and reproductive ability of the invasive pest N. viridis on citrus and non-citrus host plants cultivated in Florida. The results showed that all citrus cultivars were susceptible to N. viridis, except for Citrus aurantium, indicating the need for pest management in citrus groves. Additionally, other host plants like M. paniculata, H. rosa-sinensis, and P. granatum were found to be suitable hosts for N. viridis.

Summary: This study presents a research on the mealybug genus Planococcus known from China, recognizing 12 species. A new species, Planococcus camelliae Zhang, sp. nov., is described based on the morphology of the adult female, while the presence of P. bambusifolii (Takahashi, 1951) in China is recorded for the first time. Molecular analyses using the mitochondrial gene cytochrome c oxidase subunit I (COI) are provided, along with a key to identify species of the genus Planococcus in China.

Summary: The study investigated the host stage preference and demographic parameters of the parasitoid species, Leptomastix dactylopii, which is a parasitoid of the vine mealybug, an important pest in vineyards. Results showed that L. dactylopii preferred female mealybugs and the 3rd nymphal instar as hosts, and could be utilized for biological control of the vine mealybug. The demographic parameters of the parasitoid indicated its ability to develop on female and 3rd nymphal instar of the mealybug.

Summary: This study investigated the demography and movement behavior of Planococcus ficus, a pest that affects grapevines worldwide. The findings showed that crawlers are more likely to move upwards towards a light source, while older gravid females tend to move downward. Larger and older mealybugs have a higher chance of establishing on grapevines and have a longer survival time without food. Crawlers can survive for about 2 days without food, while females from 4-week-old cohorts can survive for about 11 days without food.

Summary: The development and reproduction of Nephus includens on Planococcus ficus were studied at four different temperatures. The results showed that temperature had a significant effect on the predator's development and reproduction. The shortest development period and highest fecundity were observed at 30 degrees Celsius. Therefore, Nephus includens could be used as a valuable tool in the biological control of vine mealybugs.

Summary: Mesh exclusion bags are used to protect young citrus trees from Asian citrus psyllid and Huanglongbing disease. However, these bags can provide a micro-habitat for other insects such as Hibiscus mealybugs. In this study, the effectiveness of entomopathogenic fungi with and without insect growth regulators against Nipaecoccus viridis, a mealybug species, was evaluated. The results showed that formulated Beauveria bassiana-based products, alone or combined with an IGR, can effectively manage N. viridis populations on citrus trees protected with mesh exclusion bags.

Summary: In this study, zinc oxide nanoparticles (ZnO NPs) were synthesized from aqueous leaf extract of Acacia arabica and characterized. The results revealed that the green synthesized ZnO NPs exhibited strong antibacterial activity against foodborne pathogens, inhibiting both biofilm formation and exopolysaccharide production. The nanoparticles also showed significant antioxidant potential and were non-toxic to HeLa cell lines at the tested concentrations. These findings suggest that green synthesized ZnO NPs can be used as alternative therapeutic agents against antibiotic resistant foodborne pathogens.

Summary: This study used DNA barcoding to survey the insect diversity in Pakistan and found that the knowledge about insect species in Pakistan is limited. Most species can only be classified into order and family, with only a small portion classified into genus and species. The study also found that a majority of the insect species in Pakistan are unique to the country, but some species are also reported in neighboring countries.

Summary: This study synthesized zirconium oxide nanoparticles (ZrO2 NPs) from aqueous ginger extract and evaluated their antibiofilm and quorum quenching (QQ) potential against multi-drug resistant (MDR) Acinetobacter baumannii. The results demonstrated that ZrO2 NPs could generate reactive oxygen species (ROS) to disrupt the bacterial cellular membrane and inhibit biofilm formation by altering its chemical composition. Molecular docking studies also revealed the interaction between ZrO2 NPs and proteins involved in biofilm formation. Overall, the phytosynthesized ZrO2 NPs showed promising efficacy as alternative therapeutic options against MDR A. baumannii.

Summary: The delayed healing of wounds among people with diabetes is a severe worldwide problem. Hyperglycemia and increased levels of free radicals are the major inhibiting factors of wound healing in diabetic patients. Plant extracts rich in polyphenols can be an effective agent for wound healing, but optimization of the extraction protocol is needed to ensure efficacy.

Summary: Honey bees are effective sentinels for environmental contaminants, particularly particulate matter. Exposure to particulate matter had harmful effects on the foraging performances of honey bees, resulting in reduced foraging rates and speeds. The presence of particulate matter also led to a decrease in bee population, smaller broods, and lesser honey storage. Additionally, the presence of particulate matter affected the olfaction and flight performance of honey bees. The study also found an increase in sodium and potassium levels in the body fluids of bees exposed to agro-industrial particulate matter. The findings emphasize the importance of preventing the negative effects of particulate matter on bees' behavior and development.

Summary: The prevalence and relationships between putative native and exotic begomoviruses and the North Africa-Middle East haplotypes of B. tabaci were investigated in Oman. The study found close associations between various begomoviral species and the B. tabaci insect pest in the region. The results suggest that irrigated agriculture and global trade have facilitated the diversification and spread of begomoviruses.
