Sound and its reception are crucial for reproduction, survival, and population maintenance of many animals. In insects, low-frequency vibrations facilitate sexual interactions, whereas noise disrupts the perception of signals from conspecifics and hosts. Despite evidence that mosquitoes respond to sound frequencies beyond fundamental ranges, including songs, and that males and females need to struggle to harmonize their flight tones, the behavioral impacts of music as control targets remain unexplored. In this study, we examined the effects of electronic music (Scary Monsters and Nice Sprites by Skrillex) on foraging, host attack, and sexual activities of the dengue vector Aedes aegypti. Adults were presented with two sound environments (music-off or music-on). Discrepancies in visitation, blood feeding, and copulation patterns were compared between environments with and without music. Ae. aegypti females maintained in the music-off environment initiated host visits earlier than those in the music-on environment. They visited the host significantly less often in the music-on than the music-off condition. Females exposed to music attacked hosts much later than their non-exposed peers. The occurrence of blood feeding activity was lower when music was being played. Adults exposed to music copulated far less often than their counterparts kept in an environment where there was no music. In addition to providing insight into the auditory sensitivity of Ae. aegypti to sound, our results indicated the vulnerability of its key vectorial capacity traits to electronic music. The observation that such music can delay host attack, reduce blood feeding, and disrupt mating provides new avenues for the development of music-based personal protective and control measures against Aedes-borne diseases.

Human T-cell leukemia virus type I (HTLV-1) was the first human pathogenic retrovirus to be discovered. HTLV-1 induces a T-cell malignancy, adult T-cell leukemia-lymphoma (ATL), and inflammatory diseases, such as HTLV-1-associated myelopathy (HAM), HTLV-1 uveitis (HU), and HTLV-1-associated pulmonary disease (HAPD). Importantly, HTLV-1 maintains persistent infection by regulating viral gene expression and disrupting host signaling pathways - activities that are closely linked to its pathogenicity.

During oxidative phosphorylation, the leaked electrons generate superoxide anions to attack the mitochondrial inner membrane and impair mitochondrial activity. Three superoxide dismutases (SODs) are secreted to degrade host superoxide anions in Verticillium dahliae. However, the roles of mitochondrial SODs (mtSODs) in superoxide anion detoxification and in virulence are unknown in this fungus.

Contractile injection systems (CISs) - bacteriophage tails, tailocins, and bacterial type VI secretion systems - penetrate the envelope of the target cell by employing a contractile sheath-rigid tube mechanism. The membrane-attacking end of the tube carries a spike-shaped complex that ends with a spike tip. In bacteriophage P2, the spike and spike tip proteins are fused, and we used this phage to show that sheath contraction results in the translocation of the spike into the periplasm of the host cell.

As viral pathogens typically employ double-stranded RNA (dsRNA), host identification, modulation, and response to dsRNA is key. However, dsRNA is also abundant in host transcriptomes, raising the question of how these molecules can be differentiated.

Emerald ash borer (Agrilus planipennis Fairmaire) is an invasive wood-boring beetle that has killed millions of ash trees (Fraxinus spp.) across North America. In 2014, emerald ash borer was discovered attacking white fringetrees (Chionanthus virginicus L.
