Article Synopsis
  • Economic losses in livestock farming due to ticks are significant, with research focusing on plant extracts facing obstacles, particularly around formulation for effective use.
  • A study aimed to create a nanoformulation (AScn) using polycaprolactone nanoparticles and a hydrogel (ASlh) with xantan gum to enhance the efficacy and contact time of an extract against tick larvae.
  • Results showed the hydrogel (ASlh) significantly increased mortality of ticks at a concentration of 20 mg/mL, achieving 91.48% mortality, indicating its potential as a viable solution for tick control.

Article Synopsis
  • - The classification of termites, particularly the diverse Neoisoptera group, needs significant updates due to many incorrectly grouped taxa; researchers propose a new classification based on genomic analyses.
  • - The study identifies seven monophyletic family lineages within Neoisoptera and 18 subfamily lineages in the species-rich Termitidae, including several new subfamilies and the revival of some older ones.
  • - The new classification method is built on clear monophyletic lineages, which enhances its stability and adaptability for future studies, allowing it to incorporate yet-to-be-discovered species easily.

The ever-growing group of people living with dementia (PLWD) and their relatives face great challenges. The Covid 19 pandemic has once again placed a particular challenge on this vulnerable group. What started a decade earlier with telephone-based support groups experienced a real push during the pandemic in the form of video-based self-help services.

The neotropical Apicotermitinae is a common and widespread clade of mostly soil-feeding soldierless termites. With few exceptions, species of this group were originally assigned to the genus Müller, 1873. The application of internal worker morphology coupled with genetic sequencing has recently shed light on the true diversity of this subfamily.

Article Synopsis
  • A new genus and species of soldierless termites from South America has been described by Constantini, Castro & Scheffrahn.
  • The identification is based on unique morphology of the enteric valve, which has six slightly asymmetric cushions and central pouches made of smaller scales.
  • The species is supported by COI molecular sequence data and is found from Tobago to northern Argentina.
