Author summary Genetic elements known drive can manipulate offspring, favouring or sex. fascinating phenomenon has inspired development systems several organisms. where females harbour XX XY chromosomes respectively, X-chromosome ‘shredded’ during gametogenesis, production non-functional X-bearing sperm, while are left intact able fertilise eggs. These produce offspring extremely biased towards males, which used tools control harmful insect populations. our applied molecular strategy Our aim was cellular consequences shredding chromosome, impact meiosis selection, achieve offspring. outcome study enhances understanding biological mechanisms behind sex-ratio distorters could inform ratio. Additionally, present sexing mostly females, providing fundamental deadly vector.

Acoustic communication plays an important role during the courtship of many mosquito species. Male mosquitoes show strong attraction to female wing beat frequencies, mediated via spectral matching between frequency and male ear mechanical tuning frequency. Such acoustic typically occurs within swarms, male-dominated aggregations with species-specific properties. Despite hundreds relevant publications being available, lack a central platform hosting all associated data hinders research efforts limits cross-species comparisons. Here, we introduce MACSFeD (Mosquito Communication Swarming Features Database), interactive for exploration our comprehensive database containing 251 unique reports focusing on different aspects communication, including hearing function, phonotaxis, as well swarming parameters. serves easily accessible, efficient, robust visualization tool research. We envision that further in-depth studies could arise following use this new platform. Database URL: https://minmatt.shinyapps.io/MACSFeD/.
