Summary: This study assessed the damage inflicted on horse chestnut leaves by the horse chestnut leaf miner and the Guignardia aesculi fungus, and modeled their interaction. Results showed that G. aesculi is the superior competitor, with overall leaf damage exceeding 50% in no-raking sites in August. The findings highlight the intricate interplay between insect pests and fungal pathogens, calling for further research in this understudied area.

Summary: With the help of volunteers, the secondary range of the invasive alien insect pest, horse-chestnut leaf miner, was determined in European Russia. The pest was confirmed in 24 administrative regions and produced outbreaks in southern Russia in 2021. The DNA analysis showed the presence of two haplotypes, indicating a further range expansion of the pest.

Summary: The presence of leaf miner infestation on Aesculus hippocastanum trees affects cambial activity and differentiation of conductive tissues, leading to changes in wood structure and narrower annual growth rings. These changes result in reduced cambial divisions, earlier cessation of wood differentiation, and altered wood structure with more vessels of smaller diameters in infested trees. However, the infestation does not influence secondary phloem differentiation or theoretical hydraulic conductivity.

Summary: Cameraria ohridella is a highly invasive pest of horse chestnut. The insecticide Cyantraniliprole, known for its potential effectiveness, has not been tested against this pest. All three application methods were effective, although they had different time frames for action. The rate of acropetal translocation was higher than basipetal translocation, and there was a correlation between cyantraniliprole concentration and photon emission in the treated plant tissues.

Summary: Using alien insect species as food and feed can address protein shortage and promote sustainable feed production, but their invasive potential needs to be considered due to its threat to biodiversity. While the European Union has authorized eight insect species for use as feed ingredients, the risk assessments have mostly focused on northern European regions. Some of these insect species have invasive potential and can negatively affect local ecosystems and cause economic losses. It is recommended to conduct risk assessments and monitoring programs in other EU regions, and also consider native insect species as alternative feed ingredients.

Summary: The study showed significant differences in the leaf eco-stoichiometric characteristics and soil properties of Spartina alterniflora at different tidal levels, with soil salinity and soil carbon-nitrogen ratio identified as key factors affecting its eco-stoichiometric characteristics. Nitrogen limitation was detected in the study area, indicating an important finding for understanding the nutrient distribution mechanisms and invasion strategy of S. alterniflora in the ecosystem.

Summary: The authors studied the seasonal development of horse chestnut leaf miners in green plantations of the Kharkiv region, comparing the data with other regions. They determined the sum of effective temperatures required for one generation of horse chestnut leaf miner moth. The research showed overlapping generations and increasing density of mines, with the highest density of butterflies found in the lower part of tree trunks.

Summary: Tuta absoluta, also known as Tomato Leaf Miner (TLM) moth, is a destructive pest that primarily mines on leaves and fruits of solanaceous crops. Its detection in Nepal in 2016 has raised concerns about the potential for significant yield loss. Therefore, farmers and researchers need to implement effective management strategies to increase tomato production in Nepal.

Summary: Climate change-induced droughts and insect outbreaks are causing more frequent and widespread forest mortality. A historic drought triggered a multi-decadal growth decline in trembling aspen, predisposing them to mortality during a leaf miner outbreak. This suggests that as the climate warms and insect outbreaks increase, we can expect persistent declines in tree growth and increased mortality.

Summary: The invasive spotted wing drosophila, Drosophila suzukii, negatively affects fruit and wine production and has been found to attack a wide range of potential host plant species in forest ecosystems. Its attacks on fruits lead to severe decay symptoms, and the abundance of D. suzukii is high, outcompeting native frugivorous species. This invasive species may have far-reaching consequences for ecosystem-level processes such as seed dispersal mutualisms.

Summary: The study explored the ecological sensitivity of sessile herbivorous insects to aerially applied insecticides in German oak forests. The results showed that the insecticides had varying effects on different guilds of insects, with diflubenzuron affecting leaf-miners but not gall-inducers, and tebufenozide showing a similar pattern. Overall, the net outcome of the insecticide treatment was positive for certain guilds but negative for others, highlighting the importance of considering species biology and interactions in risk assessment studies.

Summary: The study suggests that branch-localised induction of plant defenses and vertical stratification in forest canopies have significant impacts on herbivore assemblages, affecting predation and herbivory. Diverse factors, including branch-localised induction, variation between tree individuals, and predation, contribute to the variation across canopies.

Summary: Ants coordinate foraging behavior through species-specific trail pheromones. Previous studies on the trail pheromone composition of Solenopsis invicta, a notorious invasive ant species, have provided contrasting results. This study reanalyzed the chemicals in the ant's gland extract and confirmed the major components of the trail pheromone.

Summary: Extensive transcriptomic analyses have revealed distinct differences in the gene expression profiles of maize plants upon shoot and root attack, both locally and distantly from the affected tissue. This study provides detailed insights into the specificity of plant defense responses and offers a molecular resource for further genetic studies on maize resistance to herbivores. It also paves the way for novel strategies to enhance maize resistance to pests.

Summary: Through studying the volatiles emitted by rice plants, we found that they have direct and indirect resistance against the striped stemborer. The plants exposed to these volatiles exhibited increased expression of defense genes, higher levels of defensive substances, and attraction to parasitic wasps. These findings provide new management strategies to enhance rice resistance.

Summary: Cotton plants respond to herbivory by increasing gland density and defensive compounds, which is primarily triggered by physical damage rather than insect-derived elicitors. Repeated mechanical damage causes systemic induction of cotton glands without needing the presence of caterpillar regurgitant. This study provides valuable insights into chemical ecology and plant defense theory, and can be effectively used in practical classes.
