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.

Forschende unter anderem von der Schwedischen Universität für Agrarwissenschaften (SLU) haben entdeckt, warum bestimmte Frauen, insbesondere Schwangere, Mücken anziehen. Sie identifizierten 27 chemische Verbindungen in Duftproben, wobei Octenol eine Schlüsselrolle spielt. Die Erkenntnisse könnten die Entwicklung von Mückenfallen und Abwehrmitteln verbessern.
Alex Toussaint und Clovis Piedallu haben eine 40 Gramm schwere, autonome Drohne entwickelt, die Mücken im Flug anhand ihrer akustischen Signatur erkennt und eliminiert.

Dry winters and springs continue to suppress mosquito populations in Sweden. Researchers at the National Veterinary Institute predict another season with unusually few mosquitoes.
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.

Artificial streetlights are causing thousands of woodlice to form large circular "death spirals" in northern Israel. The behavior was documented by researchers from The Hebrew University of Jerusalem. It marks the first known instance of such collective movement in these ground-dwelling isopods.
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.
