Summary: Research showed that Cerambyx welensii has a broad sensitivity to tree volatiles, with strong EAG responses to specific blends of monoterpenes emitted by its main oak hosts. Female C. welensii may be able to detect oak trees with a limonene-type chemotype, influencing their host choice. Additionally, high antennal activity was observed in response to odorants from non-host tree species, which may have implications for pest management strategies.

Summary: Methyl salicylate (MeSA) as a volatile compound acts as an inducer of plant defense against pathogens and certain herbivores, particularly aphids. Exposing plants to MeSA reduced aphid settling and altered their preference for plant odor. MeSA exposure induced resistance factors in barley plants against bird cherry-oat aphid, highlighting its potential for aphid pest management.

Summary: Biological control is an important process for sustainable plant production, and this study reviews microbes that could be used as pesticides against microbial plant pathogens, insects, and nematodes. The focus is on beneficial microbes in the rhizosphere that promote healthy plant growth and have pathogenic effects on plant pathogens. Metabolites released by these microbes inhibit the growth of bacterial and fungal pathogens and are toxic to insects and nematodes. The study evaluates the use of these metabolites for plant protection in the rhizosphere.

Summary: This study demonstrated that soil cadmium (Cd) stress can significantly induce leaf volatile organic compound (VOC) emissions in Populus yunnanensis, and the released VOCs are less attractive to both specialist and generalist herbivores. Furthermore, the herbivores' odor selection and oviposition preference were negatively correlated with leaf total VOC emissions, confirming the defensive role of Cd-induced VOCs. This finding expands our understanding of the Elemental defense hypothesis and provides new insights into predicting herbivore damage in metal-polluted habitats.

Summary: Pathogen suppression and induced systemic resistance are alternative strategies for sustainable agriculture, and Actinobacteria have been widely used as biocontrol agents. Actinobacteria not only produce substances and enzymes that antagonize pests, but also stimulate plant growth. They can also induce systemic resistance against pathogens, but the mechanisms are still unclear.

Summary: In this study, we found that the growth, sporulation, and production of volatile organic compounds (VOCs) and indole-3-acetic acid (IAA) of the fungus T. atroviride were affected by mechanical damage. We observed that mycelium injury combined with photoperiod conditions triggered conidiogenesis, stimulated IAA secretion, and enhanced the emission of specific compounds, while darkness had the opposite effects. Furthermore, we also found that specific compounds produced by the fungus inhibited the growth of a necrotrophic fungus. These findings suggest that fungal integrity and light signaling play a role in modulating the biochemical and ecological attributes of T. atroviride.

Summary: This study investigated how BVOCs influence plant-insect communication, specifically focusing on the interaction between Japanese white birch and a leaf beetle in O3-polluted urban forests. Results showed that the leaf-emitted BVOCs play a role in attracting the leaf beetle, but the composition of BVOC blends varied among Betulaceae host trees. The presence of O3-reactive species in the emissions from white birch could disrupt the communication with the leaf beetle, suggesting a complex interplay between BVOCs, host preferences, and O3 pollution in plant-insect interactions.

Summary: This study characterized and analyzed the detoxification gene CYP302A1 in the fall armyworm (FAW) and found higher expression levels in midgut tissue and older larvae. Increased P450 activity in the midgut of FAW larvae after exposure to rice plants was observed, as well as higher mortality in larvae treated with PBO followed by exposure to rice plants. Additionally, downregulation of the CYP302A1 gene, along with higher mortality, reduced larval weight, and shorter developmental time, was observed in dsRNA-fed larvae exposed to rice plants. Results suggest that the inducible P450 enzyme system and related genes enable herbivores to adapt to diverse host plants by utilizing secondary compounds.

Summary: This study assessed the resistance and fitness costs of the fall armyworm to the insecticide indoxacarb. After 24 generations of selection, the resistance to indoxacarb significantly increased, accompanied by longer developmental time, shorter adult longevity, and lower fecundity. The study also suggested the involvement of P450 enzymes in indoxacarb resistance. These findings provide valuable insights into the resistance mechanism of the fall armyworm and guidance for pest management decisions.
