Mosquitoes from the Culex pipiens complex are found worldwide and have been the focus of numerous studies due to their role as vectors of human pathogens. We investigated the population genetic structure of Cx. pipiens s.

Lysosomes are digestive organelles that are crucial for nutrient sensing and metabolism. Lysosome impairment is linked to a broad spectrum of metabolic disorders, underscoring their importance to human health. Thus, lysosomes are an attractive target for metabolic disease therapies.

Gaucher's disease (GD) is a genetic disease characterized by a mutation in the metabolic enzyme glucocerebrosidase (GBA1), leading to the accumulation of glucosylceramide in tissues. We previously discovered that a -inserted mutation in the gene of fruit flies, , mimics human neuronopathic GD (nGD) characteristics, providing a promising model for studying the molecular mechanisms of the disease. We also reported that extremely low-frequency electric fields (ELF-EFs) promote sleep and extend the lifespan of wild-type flies.

Mosquitoes are responsible for the transmission of numerous pathogens, including Plasmodium parasites, arboviruses and filarial worms. They pose a significant risk to public health with over 200 million cases of malaria per annum and approximately 4 billion people at risk of arthropod-borne viruses (arboviruses). Mosquito populations are geographically expanding into temperate regions and their distribution is predicted to continue increasing.

In modern agriculture, control of insect pests is achieved by using insecticides that can also have lethal and sublethal effects on beneficial non-target organisms. Here, we investigate acute toxicity and sublethal effects of four insecticides on the males' sex pheromone response and the female host finding ability of the Drosophila parasitoid Leptopilina heterotoma. The nicotinic acetylcholine receptor antagonists acetamiprid, flupyradifurone and sulfoxaflor, as well as the acetylcholinesterase inhibitor dimethoate were applied topically as acetone solutions.
