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: Species range expansion induced by climate change and human activities can have negative impacts on native populations and communities. This study provides evidence that a range-expanding wood-borer moth heavily attacks a foundation plant species in salt marshes, impacting its recruitment and succession. The research also highlights the importance of maternal oviposition effects in range-expanding insects using novel host-plants.

Summary: Studies have shown that the endophytic EPF Beauveria bassiana can affect the oviposition selection of Asian corn borer. However, the survival rate of Asian corn borer larvae, pupae, and adults is lower on B. bassiana-colonized maize plants, which is correlated with lower plant nitrogen content.

Summary: Species with large geographical ranges provide a model for studying how populations respond to different local conditions, especially in terms of climate variation. Maternal behavior, such as nest-site choice, can mitigate the effects of divergent climatic conditions across a species' range. This study found that painted turtles non-randomly nested in microhabitats with less canopy cover and higher nest temperatures, suggesting that nest-site choice is homogenizing nest environments and slowing embryonic evolution. However, nest-site choice may not compensate for rapid increases in local temperatures.

Summary: The selection preferences of different morphs of aphid vectors for infected or noninfected wheat plants were studied, revealing that infective aphids prefer noninfected plants while noninfective aphids tend to select infected plants, possibly due to the influence of volatile components. Furthermore, virus-infected plants release increased volatiles which may attract noninfective aphids in a concentration-dependent manner, providing new evidence for the vector manipulation hypothesis.

Summary: Plant viruses are often transmitted by insect vectors, and the transmission can be affected by the preferences and infection status of the vectors. Mathematical modelling has been used to study the effects of vector preferences and infection on plant virus epidemics, showing how these factors impact disease incidence and transmission dynamics. This research highlights the importance of considering the interaction between virus infection, vector behavior, and population dynamics for a comprehensive understanding of plant virus epidemics.

Summary: In nature, many invertebrates interact and associate with plants, but our knowledge of spiders and their plant associations is limited. This review focuses on web-building spiders and provides an overview of their interactions with plants. Specifically, it examines the notable interactions of both non-web-building and web-building spiders with plants, and discusses specific associations of web-building spiders with plants, such as the Acacia-Eustala association in Panama. The review also explores mechanisms for host plant location and suggests future research directions.

Summary: The presence of rhizobia colonization influences the effects of plant viruses on host chemistry, vector behavior, and virus transmission. The co-colonization of plants by rhizobia and viruses led to increased dispersal of aphids and higher transmission rates. However, virus infection suppressed the production of volatile compounds, but aphids did not show preferences for these compounds.

Summary: The relative importance of ecological factors and species interactions for shaping species distributions is still debated. Species abundances depended on host plants, followed by climatic factors, with a dose of competition between species sharing host plants. The relative importance of these factors mildly changed among the three host plant groups.

Summary: Plant invasions pose a threat to global ecosystems and biodiversity, especially in the face of climate warming. This study investigated the impact of elevated temperature on the volatile emissions of invasive plants and the preferences of herbivores. Results showed that while elevated temperature did not change the behavioral preferences of herbivores towards invasive plants, it indirectly increased oviposition preference for native plants, potentially leading to increased damage to native plants under global warming scenarios.

Summary: Rice dwarf virus (RDV), transmitted by insect vectors Nephotettix virescens and Nephotettix cincticeps, affects rice yield and causes economic losses. Two volatiles emitted from RDV-infected rice plants, namely (E)-beta-caryophyllene (EBC) and 2-heptanol, were found to influence the olfactory behavior of non-viruliferous and viruliferous N. virescens. EBC attracts non-viruliferous N. virescens towards infected rice plants, promoting virus acquisition, while 2-heptanol repels viruliferous N. virescens to prefer virus-free plants, facilitating virus transmission.

Summary: This study compared the reproductive capacities, ovary development, and vitellogenin (Vg) gene expression in spinosad-susceptible and -resistant western flower thrips to investigate the reason for the fitness cost in spinosad resistance. The results showed that the spinosad-resistant strain exhibited a decrease in fecundity and shortened ovariole length compared to the susceptible strain. The downregulated expression of Vg was found to contribute to these phenotypic changes and the fitness cost.

Summary: Detoxification is crucial for agricultural pests to withstand pesticides, and cytochrome P450s, carboxyl/choline esterases (CCEs), and glutathione-S-transferases are responsible for this ability. Previous studies mainly focused on the effects of upregulation, downregulation, or mutation on CCEs, while the role of alternative splicing remains unclear. In this study, we identified two variants of TcCCE23 in Tetranychus cinnabarinus, and found that splicing affected the detoxification ability of TcCCE23. Overexpression of the spliced variant, CCE23-V2, resulted in higher mortality of mites under fenpropathrin exposure compared to the control group. Furthermore, molecular docking analysis suggested that splicing enlarged the substrate binding cavity of CCE23-V2, potentially enhancing its ability to accommodate fenpropathrin molecules. These findings indicate that splicing plays a significant role in enhancing the detoxifying capability of TcCCE23.

Summary: Communities of bacteria, especially symbionts, play a vital role in the growth and development of pests like Bemisia tabaci Mediterranean (MED), an invasive insect. This study investigated the infection density patterns of Cardinium in MED populations and the effects of high temperatures. Two isofemale lines from the same Chinese population and from other countries were examined using different techniques. The results revealed two different infection density patterns of Cardinium and showed that high temperature significantly affected the diversity and functions of bacterial communities in whiteflies with high-density Cardinium.

Summary: Bradysia odoriphaga is a major insect pest in Asia that affects 30 commercial crops in seven plant families. The long-term use of chemical pesticides has led to resistance in these pests, as well as environmental issues and food contamination. In this study, the BodoOBP10 protein in B. odoriphaga was identified as playing a role in the recognition and localization of host plants. Silencing BodoOBP10 expression through RNA interference significantly reduced the insects' response to sulfur-containing compounds.

Summary: In this study, the diamondback moth and its pathogen Bacillus thuringiensis were used to investigate the adaptive evolutionary mechanism. The host adaptation to the pathogen was associated with the insertion of a retrotransposon into the promoter of the MAP4K4 gene. This insertion enhanced the host defense mechanism against the pathogen by activating a hormone-modulated MAPK signaling cascade. This research provides new insights into the coevolutionary mechanism between host organisms and their microbial pathogens.

Summary: Investigation found that acaricides inhibiting mitochondrial succinate dehydrogenase (SDHIs) have excellent control over phytophagous mites but limited toxicity to predatory mites and other beneficial organisms. The molecular mechanism of this selectivity is not fully understood. The main reason for this selectivity is that SDHIs have approximately 200-fold stronger inhibition on the SDH target in spider mites compared to predatory mites, indicating strong target-site selectivity.

Summary: Insect vectors and insect-borne plant viruses pose a serious threat to agricultural production. Insecticides are commonly used to prevent the transmission of insect-borne viruses. However, the relationship between insect vector resistance and arboviruses has not been extensively studied. This study explores the effect of Tomato chlorosis virus (ToCV) on the insecticide resistance of Bemisia tabaci MED. The results show that ToCV infection upregulates detoxification-related genes and increases the activity of detoxification enzymes in B. tabaci, leading to reduced sensitivity to certain insecticides.
