Summary: Chromosome rearrangements in aphids have led to a significant reorganization over the past 30 million years, resulting in the inability to determine chromosome homology between Aphidini and Macrosiphini tribes. Despite rapid sequence evolution, low gene expression, and high transposable element load, gene content of the aphid sex (X) chromosome remained unchanged. Blood-feeding hemipterans, despite being more diverged, have conserved synteny, suggesting that rapid evolution of genome structure may be a unique characteristic of aphids.

Summary: The study found hundreds of genes deregulated in viruliferous aphids fed on TuYV-infected plants, with only a few genes linked to receptor activities and vesicular transport being common with those fed on an artificial medium containing purified virus particles. Behavioral studies showed that aphid locomotion behavior was affected by feeding on infected plants but not on artificial medium. This indicates that acquisition of TuYV particles alone leads to moderate gene deregulation, while higher gene deregulation is associated with aphid ingestion of phloem from infected plants, suggesting a major role of infected plant components on aphid behavior.

Summary: This study examined the influence of insect herbivory and AM fungal colonisation on maternal effects in the annual forb Senecio vulgaris over four successive generations. The results showed strong evidence of maternal effects in the second plant generation, and gradual recovery in subsequent generations. Aphid attack enhanced these effects, while AM fungi had little influence.

Summary: The study found that substrate-borne vibrations transmitted through the host plant can reduce the number of three aphid species, while airborne vibrations played through speakers had no detectable effect. These results suggest that non-specific substrate-borne vibrations may affect pests not known to use vibrations to communicate and should be further explored as a physical pest control method. Further research is needed to investigate longer-term effects of non-specific vibrations on pests, their host plants, and their natural enemies.

Summary: This study investigated the toxicity of essential oils (EOs) from Santolina chamaecyparissus (L.) and Tagetes patula (L.) on two aphid species, showing that EOs can impact aphid development and physiological processes through oxidative stress induction. The study also found that EO treatment reduced aphid fecundity and intrinsic rate of increase, while increasing levels of reactive oxygen species and lipid peroxidation in aphid tissues. Additionally, antioxidant enzyme activities were elevated in response to EO treatment, suggesting that oxidative stress plays a key role in the toxicity of EOs towards aphids.

Summary: The purpose of this study was to clone and investigate the function of S-adenosylmethionine synthase (BtSAMS) from Balsas teosinte in Arabidopsis plants. BtSAMS showed increased expression in response to aphid infestation in Z. mays ssp. parviglumis. Transgenic Arabidopsis plants expressing BtSAMS exhibited prolonged vegetative growth and increased resistance to peach aphids. BtSAMS may be a suitable candidate gene for conferring resistance to peach aphids in plants.

Summary: This study assessed the impact of basil on aphid biological control by predatory lacewings, revealing that basil enhanced lacewings' longevity and fecundity, and modulated their colonization patterns. High density intercrop basil arrangements led to increased lacewing colonization rates, longer population persistence, and faster aphid decline, highlighting the potential of functional plants in enhancing pest control in agricultural systems.

Summary: This study introduces a method using non-viruliferous aphids to acquire Brassica yellows virus from transgenic Arabidopsis thaliana and transmit it to healthy plants. While transmission rate was lower from frozen infected leaves compared to fresh ones, there was no significant difference in acquisition rates. This novel method can be utilized for viral inocula preservation, evaluation of host varietal resistance to BrYV, and investigation of interactions among the virus, aphids, and hosts.

Summary: The ladybird Eriopis connexa is an important natural enemy for controlling pest arthropods in agricultural systems. In this study, the suitability of three species of spider mites (Tetranychus evansi, Tetranychus urticae, Tetranychus ogmophallos) and a species of aphid (Myzus persicae) as prey for E. connexa was evaluated using two-sex life table parameters. The results showed that E. connexa could complete immature development on all prey species except for T. evansi. Among the prey species that supported E. connexa's development, T. urticae and M. persicae provided a faster development time. Oviposition days, longevity, and fecundity of E. connexa were significantly higher on T. urticae and M. persicae compared to T. ogmophallos. The net reproductive rate, intrinsic rate of increase, and finite rate of increase of E. connexa were also higher when feeding on T. urticae and M. persicae. Based on the overall performance of E. connexa, the order of prey suitability was M. persicae > T. urticae > T. ogmophallos > T. evansi.

Summary: In the last decade, genome editing technologies have become highly effective and are being used in clinical trials for treating genetic diseases. However, the debate about the bioethical and regulatory practices of genome editing still lacks satisfactory answers, despite over 50 years of discussions on the frontiers of genetics in human health and evolution. The delay in finding answers is due to an excessive focus on the effectiveness of the technologies in regulatory practices, rather than considering other factors such as accessibility and acceptability at a bioethical level.

Summary: This study analyzed the mutations in the for gene sequence in clones of the peach potato aphid and found that mutations were associated with a reduced number of winged females and the absence of exploratory behaviors. Quantitative PCR experiments confirmed similar results in clones with conserved coding sequences but low expression levels. The comparison of for transcriptional levels between different clones showed significant differences. Screening for for gene sequences may be useful in predicting peach potato aphid invasions.

Summary: The project aimed at digitizing specimens and studying the scientific research of zoologist Daniele Rosa found 19 oligochaete samples studied by Rosa in the historical collections of the Museum of Zoology and Comparative Anatomy, including holotype specimens of Allolobophora cuginii described by Rosa in 1905. The survey also identified specimens that could potentially be a second bolotype described by Rosa, but the lack of inventory data makes this attribution uncertain at present.
