salivary gland hypertrophy virus (MdSGHV) affects house flies by enlarging salivary glands, impeding ovary development in females, and mating behavior in both males and females. It is not known if this virus impacts the quantity of saliva produced by house flies. This study aimed to establish baseline saliva quantities in healthy across sexes and ages and examine how MdSGHV infection influences saliva output in 5-day-old males.

Article Synopsis
  • The text discusses a diverse group of unicellular fungi that live as obligate symbionts in various arthropods, particularly targeting species like bees and butterflies.
  • It highlights that these fungi have experienced significant genome reduction, losing many genes essential for free-living yeast, notably lacking those related to energy production and showing diminished endocytosis-related genes.
  • The study uncovers specific genetic motifs linked to gene expression and reveals interesting phylogenomic insights, including host-switching events, which could inform strategies for managing these pathogens.

Glutathione S-transferases (GSTs) are an important class of enzymes that facilitate the conjugation of reduced glutathione (GSH) with electrophilic substrates, including some insecticides. Two inhibitors of GSTs, ethacrynic acid (EA) and diethyl maleate (DEM), are often used as diagnostic tools to implicate GST involvement in insecticide resistance, but their modes of action against insect GSTs are largely assumed based on mammalian studies. In mammalian studies, there are two proposed mechanisms of inhibition of GST function by EA and DEM: 1) scavenging or "depleting" cytosolic GSH through non-enzymatic conjugation, and 2) inhibition of GST activity directly by the inhibitor-GSH conjugate (EA-SG and DEM-SG).

House flies (Musca domestica L.) (Diptera: Muscidae) are challenging pests to control. Biological control using Carcinops pumilio beetles may help to reduce house fly populations.

House flies are notoriously difficult to control, owing to their tendency to live in close relationships with humans and their livestock, and their rapid development of resistance to chemical controls. With this in mind, we explored an alternative chemical control, a spatial repellent to deter L. from points we wanted to protect (i.
