Summary: The effects of substrate-borne vibration with frequencies of 30 and 300 Hz on the population of Trialeurodes vaporariorum and fruit sets in greenhouse tomatoes were investigated. The results showed that 300 Hz vibration significantly reduced the number of T. vaporariorum, while 30 Hz vibration had a suppressive effect at higher acceleration. Regarding pollination, 300 Hz vibration did not affect fruit sets, while 30 Hz vibration increased fruit sets. This study suggests that applying substrate vibration to tomatoes can effectively control T. vaporariorum infestation and promote pollination.

Summary: The study analyzed gene expression differences in copepods during different reproductive processes, identifying indicators for diapause preparation and potential genes for functional studies. Through transcriptomic data and functional analysis, physiological differences in copepods during different reproductive and dormant phases were revealed.

Summary: The fruit fly reduces reproduction in response to cold, but can recover through AstC signaling. AstC stimulates egg production by activating AstC-R2 neurons. These findings have implications for controlling pest and disease vector populations.

Summary: The study examined the impact of nutrition in the first 12 weeks of life on testicular and sexual development in bull calves. Results showed that offering a high plane of nutrition not only improved growth and metabolic status, but also advanced testicular development for precocious sexual maturation.

Summary: The development pattern of termite queens and workers differ, with the former developing through nymphal line and the latter through apterous developmental line. However, in Cavitermes tuberosus, secondary reproductives can also develop through nymphal line. The study showed that gene expression differs between primary queens and secondary queens, with muscle development and contraction, flight, and olfactory learning genes down-regulated in both primary and secondary queens.

Summary: This study explores the possible use of conspecific male cues in wolf spiders and found that male wolf spiders can assess their competitive environment and adjust their reproductive behavior by using substrate-borne vibratory cues from conspecific males. The assessment and perception of density-dependent conspecific courtship signaling can be used as social information to adjust the reproductive behavior of focal males.

Summary: Substrate-borne vibration, previously undocumented in T. oceanicus, has been identified in both typical and purring male morphs during courtship, suggesting a shared mechanism (wing movement) for producing both airborne and substrate-borne sounds. While purring males produce higher frequency songs in both airborne and vibrational channels compared to typical males, there is no difference in amplitude between morphs in the substrate-borne channel, which may have implications for mating decisions as females prefer louder songs. This study paves the way for further exploration of variation in substrate-borne vibrations, receiver responses, and evolution of substrate-borne vibrations alongside rapid shifts in airborne acoustic signals in T. oceanicus.

Summary: In a well-known paper from 1964, Charles Michener investigated the relationship between colony size and reproductive efficiency in hymenopterous societies. He concluded that efficiency decreases with increasing colony size. However, subsequent studies have challenged this conclusion by pointing out various biases in Michener's data and suggesting alternative explanations for the observed pattern. Analyses of post-1964 studies suggest that, for most species, there is no loss of efficiency with increasing colony size. Two exceptional taxa, halictid bees and independent-founding paper wasps, show negative trends consistent with Michener's hypothesis in some species. Various mechanisms are proposed to explain how efficiency can change with colony size.

Summary: This study assessed different sugar alcohols as more species-selective feeding stimulants for pest insects. The results showed that sorbitol and xylitol were attractive to wasps, while erythritol acted as a non-nutritive feeding stimulant. None of the sugar alcohols acted as feeding stimulant for bees.

Summary: This study investigated the effects of excluding mammals and including native animals inside the Orokonui Ecosanctuary fence on beetle abundance, diversity, and community composition. The results showed that sites inside the fence had a higher abundance and diversity of beetles.

Summary: Behavioral shifts in animals are often driven by ontogenetic processes such as aging or life experiences, through changes in their physiology and/or gene expression. Colonies of eusocial animals such as social hymenopterans may experience behavioral shifts at the colony-level due to maturation and/or experience throughout the colony cycle. In this study, we investigated the nest defense behavior of social wasp Vespula vulgaris colonies and found that nest defense behavior decreases over time, regardless of how frequently they faced a simulated predator attack.

Summary: Xylem anatomy is crucial for studies in the evolution of terrestrial plants, tree ecophysiology, forestry, and wood science. Utilizing sanded wood surfaces for microscopic level investigations can provide clear visualization of xylem micro-features, offering advantages such as cost and time effectiveness, large sample area, intact cell walls, and preserved chemical content. Comparing to traditional wood sections, using sanded wood surfaces can be a simpler and more efficient method for xylem microscopy and automatic image analysis of xylem structure.
