Summary: Chemical elicitors, such as 4-chlorophenoxyacetic acid (4-CPA), can induce chemical defenses in rice plants to protect against white-backed planthoppers (WBPH). 4-CPA treatment modulates peroxidase activity and induces the deposition of lignin-like polymers, while also increasing the levels of flavonoids and phenolamines. This study suggests that 4-CPA could be used as a potential chemical elicitor to protect rice crops from planthopper damage.

Summary: This study investigated the migration patterns of two rice planthoppers and five natural enemy species in eastern Asia, and found that they regularly comigrate from late April to late October each year. There was a significant positive correlation between the biomass of planthoppers and the ladybug H. axyridis, and the ratio of rice planthoppers to natural enemies varied across months. These findings provide important insights into the occurrence of rice planthoppers in eastern Asia and contribute to the regional monitoring and management of this pest.

Summary: Insectivorous bats have a positive impact on reducing plant damage and protecting yield in rice fields. Excluding bats from experimental plots resulted in increased defoliation of rice plants. Although there were no significant differences in yellowing of rice and total yield between experimental and control plots, bat activity levels correlated with rice growth. These findings highlight the importance of bats in suppressing pests and their potential for integrated pest management in Indian rice ecosystems.

Summary: Rice planthoppers (RPH) are important pests causing significant yield losses. Forecasting RPH population dynamics is challenging due to complex spatial and temporal dispersion processes impacted by multiple factors. This study proposes a deep learning-based model, combining graph convolutional network (GCN) and long short-term memory network (LSTM), to capture RPH population dynamics. The model outperforms other deep learning methods and traditional time series forecasting approaches, providing an accurate tool for forecasting RPH population dynamics and guiding pest control strategies.

Summary: Forest management intensity in Europe has varying implications for structural and environmental conditions, as well as the conservation of ecological communities. This study found that silvicultural treatments promoting rare habitat structures can enhance trap-nesting bees, wasps, and their parasitoids. Forest management and associated vegetation characteristics influenced the abundance, richness, parasitism rates, and network structure of the bee/wasp-parasitoid communities. Clear-cut plots showed the highest abundance and richness, while unmanaged plots had the lowest. The results highlight the importance of early successional habitats and different forest management types in shaping the size and speciality of host-parasitoid networks.

Summary: Bees are exposed to multiple stressors, including pesticides and lack of flowering resources. The impacts of pesticides on bees vary depending on the type of flowering resources available. However, the effects of fungicides, which are commonly used and frequently encountered by bees, have been largely overlooked. This study highlights the importance of complementary flowering species for bumblebees' fitness and tolerance to fungicides, and calls for further research to improve guidelines for pesticide risk assessments and plant choices to protect pollinators.

Summary: Forests in Germany have roads, paths, and trails with a density of 5.03 km/km(2). The abundance, diversity, and composition of bees on these roadsides are determined by the flowering area and the presence of grassland. Creating road verges that favor native flowering plants is crucial for supporting wild bees in forest ecosystems.

Summary: Carbon-focused climate mitigation strategies are important in forests, but we need better understanding of their impact on biodiversity. A study using a large dataset from subtropical forests found that aboveground carbon was not strongly related to multitrophic diversity, while total carbon including belowground carbon was a significant predictor. Relationships were nonlinear and strongest for lower trophic levels. Tree species richness and stand age influenced these relationships, suggesting long-term forest regeneration is effective in reconciling carbon and biodiversity targets. This highlights the need to carefully evaluate the biodiversity benefits of climate-oriented management.

Summary: Pollen amino acid concentrations were lower in plants exposed to low concentrations of herbicide, and pollen fatty acid concentrations were lower in plants exposed to low concentrations of fertilizer. Nectar amino acids were higher in plants exposed to low concentrations of either fertilizer or herbicide. Exposure to low fertilizer concentrations also increased the quantity of pollen and nectar produced per flower. The insect visitation rate correlated with nectar amino acids, pollen amino acids, and pollen fatty acids.

Summary: This study analyzed the impacts of landscape heterogeneity and climate conditions on pollinating insect communities in two economically important mass-flowering crops in Europe. The results showed that flower-visiting insects responded differently to landscape diversity and climate parameters, and these responses varied depending on the crop type. Therefore, it is important to understand the population changes of pollinating insects in response to land use and climate change, in order to ensure the continued provision of pollination services to pollinator-dependent crops in the context of global change.

Summary: Most grasslands in Europe are created or altered by human activities like livestock grazing or mowing. Grassland abandonment reduces overall biodiversity, but affects different taxonomic groups differently. Factors such as management type, grassland type, and time after abandonment do not significantly influence grassland biodiversity. Maintaining grassland management is crucial for biodiversity conservation in European grasslands.
