Garlic repels mosquitoes and prevents them from mating or laying eggs. The compound diallyl disulfide is responsible for these effects. This provides a scientific basis for a belief held for centuries.
Garlic has been considered a natural mosquito repellent for centuries. Its pungent smell is believed to drive away the insects that transmit diseases such as dengue fever and malaria.

Forskere fra blandt andet Sveriges lantbruksuniversitet (SLU) har fundet frem til, hvorfor visse kvinder, og særligt gravide, tiltrækker myg. De har identificeret 27 kemiske forbindelser i duftprøver, hvoraf stoffet octenol spiller en central rolle. Opdagelsen kan føre til forbedrede myggefælder og insektmidler.
Alex Toussaint and Clovis Piedallu have created a 40-gram autonomous drone that detects and eliminates mosquitoes in flight using their acoustic signature.

Dry winters and springs continue to suppress mosquito populations in Sweden. Researchers at the National Veterinary Institute predict another season with unusually few mosquitoes.
Statens Veterinærmedicinske Anstalt, SVA, modtager i øjeblikket hundredvis af kuverter indeholdende myg fra privatpersoner over hele Sverige. Myggene indsamles som en del af citizen science-projektet Myggkartan for at kortlægge risikoen for myggebårne sygdomme.

Researchers have developed a targeted treatment using the chemical bistrifluron to control drywood termite infestations. The approach interferes with the insects' molting process and achieved high mortality rates in laboratory tests.
A new study shows that deer keds, blood-feeding flies, scale back their visual capabilities after landing on a host and shedding their wings permanently. Researchers found that the insects reduce activity in key vision-related genes by about half. The change allows them to redirect energy toward feeding and reproduction.

Researchers have discovered that distantly related butterflies and moths have used the same two genes, ivory and optix, for more than 120 million years to create similar warning colors on their wings. This finding suggests evolution can follow predictable genetic pathways rather than being entirely random. The study focused on species from South American rainforests.
