Summary: The economic importance of the double-spined bark beetle, Ips duplicatus, has been increasing in many European countries. However, many aspects of its life cycle remain unknown, making its management challenging. This study found that the adult beetles primarily overwinter in forest litter, suggesting that removing infested trees during winter is ineffective. It is suggested that trees infested with adult I. duplicatus should be removed no later than September.

Summary: This study investigated the larval development and adult flight period of M. saltuarius and provided a theoretical basis for the control of pine wilt disease. The results revealed that the full larval period was 279.6 days, consisting of five instar stages. The adults began to emerge from early May to mid-August.

Summary: The study used scanning electron microscopy to examine the sensilla on the antennae and mouthparts of adult Ips typographus, identifying ten subtypes of antennal sensilla and thirteen mouthpart sensilla subtypes. The findings provide insights into the insect-host chemical communication mechanism and feeding choices.

Summary: This study investigated the effects of ultrasound on the juvenile hormone levels in Monochamus alternatus adults, a major global pest. Results showed that different frequencies of ultrasound exposure had varying effects on the JHIII titers of beetles at different ages.

Summary: The Eurasian spruce bark beetle may use volatile cues from symbiotic fungi to improve colonization and reproductive success. Fusel alcohols and acetates in fungal VOCs are the most attractive odorants.

Summary: This study uses molecular data to classify plant-feeding beetle species, particularly Monochamus in coniferous forests, and finds that it is a monophyletic group consisting of multiple associated species. The analysis identifies 17 conifer-feeding populations within this genus, and supports the retention of all current species.

Summary: In this study, the transcriptome data of overwintering and non-overwintering larvae of Monochamus alternatus were compared to investigate the molecular mechanisms involved in overwintering. The research revealed that overwintering M. alternatus relies on energy allocation trade-off, inhibiting energy-intensive activities and diverting energy towards the synthesis of antifreeze compounds and immune response to cope with the deleterious effects of winter.

Summary: Species in the genus Cryphalus are often difficult to identify in Europe, with frequent misidentifications due to their small size, similar appearance, and lack of diagnostic characters. This study provides robust morphological and molecular evidence supporting the recognized native species of Cryphalus in Europe, based on the examination of over 1000 specimens and a thorough literature review. A key for reliable identification, including new diagnostic characters, has been constructed. The study also highlights the need for taxonomic revision of the genus Cryphalus in the entire Palearctic region.

Summary: Volatile cues play a significant role in the location and discrimination of food resources by insects. This study investigated the behavioral responses and volatile organic compounds (VOCs) of the dung beetle Bubas bison to different types of animal dung. The results showed that horse dung attracted B. bison more strongly than cattle dung, and the diet of the horses also influenced their preference. Furthermore, the abundance and composition of VOCs varied with dung type and livestock diet.

Summary: Canopy fogging was used to sample the diversity of bark and ambrosia beetles in two western Amazonian rainforest sites in Ecuador. A subset of the data analyzed in this study found high diversity of these beetles, with a total species richness estimated between 260 and 323. However, undersampling was identified as a limitation affecting the accuracy of beta diversity estimates.

Summary: In this study, the sensilla types on the antennal surface of the double-spined spruce bark beetle were analyzed using high-resolution-scanning electron microscopy. Five different types of sensilla were identified, with minor differences between males and females. This study provides a foundation for future electrophysiological research on how the beetle detects ecologically important olfactory cues.

Summary: The study revealed differences in gut bacterial composition among M. saltuarius larvae feeding on different host tree species, with greater diversity in bacterial communities and metabolites in larvae feeding on P. tabuliformis. Xylems from P. tabuliformis had more diverse and abundant secondary metabolites, leading to larvae feeding on these trees having a stronger metabolic capacity for secondary metabolites than larvae feeding on other host tree species. Correlation analysis showed that dominant bacterial genera in P. tabuliformis feeders were more negatively correlated with plant secondary metabolites compared to other host tree feeders.

Summary: Using a machine-learning algorithm and bioclimatic variables, we predicted the potential distribution areas of Monochamus carolinensis. The results showed that precipitation factors were the main drivers for its biological suitability. The future distribution areas of M. carolinensis are expected to expand to high latitudes, with only a small percentage of the current suitable areas becoming unsuitable. The largest potential distribution areas are projected for 2070, mainly due to an increase in marginally and highly suitable areas.
