The antifungal and insecticidal activities of 34 extracts from 27 plant species were evaluated against fungal phytopathogens of the genus Fusarium and Xyleborus Scolytine ambrosia beetles involved in Fusarium dieback (FD) and laurel wilt (LW) diseases. Sixteen extracts caused mycelial growth inhibition (MGI) above 23 % at 2 mg mL against F. solani, those from S. nudum and M. argyrophylla exhibited the highest MGI (57 % and 49 %, respectively). Thirteen extracts displayed significant antifungal activity against F. kuroshium, those from C. nocturnum and M. argyrophylla exhibited the highest MGI (100 % and 54.9 %, respectively). Additionally, ten plants extracts caused mortality in at least one of the beetle species tested, mainly from Solanaceae species. In the most active species, 39 phenolics were identified that may have contributed to their biological effects. This study is one of the first to report the potential of plant-derived natural products against the causative agents of FD and LW.

Saprolegniasis is one of the most dangerous fungal diseases of fish, causing significant mortality in fish hatcheries and young ones. The present study aimed to isolate and characterize the causative fungus from fingerlings of Pangasianodon hypophthalmus cultured intensively in freshwater cages in Indian reservoirs and to determine minimum inhibitory concentrations of different antifungal compounds against the fungal hyphae and zoospores. The fungal isolates grown on potato dextrose agar showed an abundance of gemmae, elongated mycelia, non-septate hyphae, primary zoospores, mature zoosporangia with numerous zoospores, cysts with bundles of long hairs and were further identified as Saprolegnia parasitica following PCR amplification and sequencing of internal transcribed spacer region.

Article Synopsis
- Aedes mosquitoes spread serious diseases like dengue and zika, leading to a need for eco-friendly solutions due to insecticide resistance and few effective vaccines.
- This study explored the interaction between the fungus Metarhizium anisopliae and Aedes albopictus, finding that the fungal infection boosts the mosquitoes' immune response and activates specific immune genes that help fight off the fungus.
- Researchers discovered a microRNA called miR339-5p that regulates immune genes; using a synthetic version of this microRNA increased the fungus's effectiveness in killing mosquitoes, indicating a potential for genetic modifications to improve mosquito control methods.

Allicin (diallyl thiosulfinate) is an abundant bioactive compound in garlic (Allium sativum L.) with broad-spectrum antiinflammatory, antifungal, antioxidant, and antitumor properties. The bioactive compounds of garlic including allicin may also help reduce the incidence of various diseases, although the individual contributions and precise mechanisms are still largely unknown.

The present study aimed to evaluate the impact of ultrasonic treatment on the development of volatile flavor compounds in beef during postmortem aging and its potential mechanism. Results showed that ultrasound treatment may cause an increase in the total content of unsaturated fatty acids, which could lead to lipid oxidation and potentially result in changes in the flavor development. Additionally, it was also found that ultrasound exacerbated protein oxidation.
