A key step in mosquito mating is auditory: Male mosquitoes detect the precise buzz of a female nearby, often in the midst of large swarms of other mosquitoes. A new study identifies a specific neurotransmitter chemical, octopamine, linked to mosquito hearing, suggesting that targeting it with insecticide could be a new potential avenue for mosquito management.
A derivative of volcanic rock called perlite shows effectiveness as a mechanical insecticide against Anopheles gambiae mosquitoes. The substance is believed to act by causing dehydration in the mosquitoes.
Last year, groundbreaking research showed Anopheles mosquitoes can ride high-altitude winds to spread far and wide. A new study published in July confirms that, after such flights, the mosquitoes remain healthy and capable of transmitting the pathogen that causes malaria.
New research shows that late-stage Anopheles gambiae larvae will eat eggs and first-instar larvae of their own species, calling into question the common view that females of the mosquito species avoid laying eggs in water where other larvae are already present.
A new study shows that fertilizer present in water where mosquitoes breed can boost growth of bacteria, algae, and fungi, which mosquito larvae feed on, resulting in accelerated larval development and greater survival rates to adulthood.
