Summary: Odontotermes parvidens is an important pest termite species that primarily feeds on cellulosic sources. Communication among nestmates is crucial for their daily activities, with sensory structures on their antennae playing a key role. Studying the antennal sensory structures of soldier and worker individuals is essential for understanding the sensory system of O. parvidens, with various types of sensilla observed and their potential functions discussed.

Summary: This study investigated ovarian development and oogenesis in the Asian subterranean termite Coptotermes gestroi, and found that ovarian development and functionality are age-dependent, with younger individuals possessing immature oocytes and functional queens always having mature terminal oocytes. Oogenesis in alate females was not uniform, and non-functional neotenics displayed variation in ovarian development. These reproductive features should be considered in evaluating their impact on colony development.

Summary: Autophagy is crucial for cell function, recycling intracellular components during starvation and eliminating spent organelles and proteins. Wdfy3 is a scaffold protein linked to intellectual disability, neurodevelopment delay, and autism spectrum disorder, and its haploinsufficiency in mice results in decreased mitophagy and affects synaptic function and glycogen synthesis.

Summary: The study on the reproductive mechanism of Reticulitermes aculabialis revealed the significant roles of different types of workers in egg-laying and chamber-making activities. Additionally, morphological changes were observed in swarmer alates, while the sex ratio of workers within the colony showed a significant dominance.

Summary: Eusocial insects, such as termites, have diverse mechanisms of reproduction. The study focused on the breeding mechanism of Reticulitermes aculabialis and found that non-reproductive worker termites performed significantly better in egg-laying and nest-building compared to primary reproductives. The study also revealed significant morphological differences in swarmer alates and the queen's weight. Workers play a crucial role in the termite colony, involving tasks like foraging, caring for young termites and eggs, constructing galleries, and assisting soldiers in defending the colony.

Summary: The mitochondrial genome of Reticulitermes ovatilabrum, 15,913 bp in length, encodes 37 genes and shows a high A/T content. Phylogenetic analysis places it closely related to R. kanmonensi and R. periflaviceps, providing a valuable resource for evolutionary studies in termites.

Summary: This study investigated the efficacy of chitinase and protease produced by Bacillus licheniformis PR2 as cuticle-degrading enzymes for the biocontrol of worker termites. Treatment with the bacterial broth culture and the crude enzyme fraction of B. licheniformis PR2 resulted in high mortality rates and visible damage to the termites' cuticles. These results suggest that the enzymes produced by B. licheniformis PR2 represent an effective eco-friendly strategy for controlling termite damage.

Summary: In this study, the phenotypic traits of F1 hybrid colonies of two destructive subterranean termite species were investigated. The nest architecture and soldier morphological traits of the hybrid colonies were compared to those of the parental species. It was found that the carton materials in the hybrid colonies were disorganized and the soldier morphometric traits varied across different mating combinations. However, four qualitative morphological differences were identified for soldier identification of hybrid Coptotermes.

Summary: Liver glycogen from diabetic individuals is more fragile than that from non-diabetic individuals, which may contribute to blood-sugar imbalance. Proteomic analysis identified three candidate proteins potentially involved in the binding mechanism of alpha particles.

Summary: The insect olfactory system plays a crucial role in insect survival and reproduction. Differences in morphological and physiological adaptations are observed in different castes of termites, and the expression patterns of olfactory genes vary among alates, workers, soldiers, nymphs, and larvae. These differences may be related to the division of labor within termite colonies.

Summary: Termites cause significant economic losses worldwide, and the use of insecticides for their control leads to further economic losses. Developing alternative termite control methods is important due to concerns for human health and the environment. This study assessed the effects of plant extracts on termites and determined the median lethal concentration (LC50) of five different plant extracts. The findings suggest that garlic, clove, lavender, cinnamon, and marjoram extracts have potential as efficient and sustainable termite control agents.

Summary: The study found that heavy weightlifting exercise results in substantial glycogen utilization from all three subcellular localizations in type 2 fibers, while primarily depleting intermyofibrillar glycogen stores in type 1 fibers. Therefore, a better understanding of the impact of resistance training on myocellular metabolism and performance requires focusing on compartmentalized glycogen utilization.

Summary: A new species of termite, Lukotermes milescaput gen. et sp. nov., is described based on a dealate specimen from Eocene amber. It is characterized by its elongate head and tibial spur formula 2:2:2. This very small termite is believed to have weight as a crucial factor in mesothermal climates rather than tropical climates.
