In recent decades, the common and the tropical bed bugs have experienced a resurgence in many parts of the world. The evolution of insecticide resistance in bed bug populations is considered a significant factor contributing to this resurgence. We analyzed samples of Cimex lectularius L.

The hemoflagellate parasite is transmitted by triatomine kissing bugs and may co-infect humans together with its Chagas disease-causing congener . Using real-time quantitative polymerase chain reaction (RT-qPCR) and antimicrobial assays, we studied () the temporal and spatial distribution of in common bed bugs, , following oral ingestion and hemocoelic injection of and () the immune responses of bed bugs induced by infections. Irrespective of infection mode, no live were present in the bed bugs' hemolymph, salivary glands, or feces.

Vector control is essential for eliminating malaria, a vector-borne parasitic disease responsible for over half a million deaths annually. Success of vector control programs hinges on community acceptance of products like long-lasting insecticide-treated nets (LLINs). Communities in malaria-endemic regions often link LLIN efficacy to their ability to control indoor pests such as bed bugs (Cimex lectularius L.

Article Synopsis
- Neonicotinoid pesticides, widely used around the world, are neurotoxic and are found in various environments, including food and water sources.
- An analysis of U.S. EPA data reported 842 non-occupational poisoning incidents linked to these pesticides from 2018 to 2022, with significant cases resulting in major illnesses and fatalities primarily associated with specific products.
- The study calls for the EPA to utilize its authority to revoke unsafe pesticide uses, emphasizing the importance of preventing neurotoxicity linked to these substances.

Over the last two decades, an increase in bed bug infestations has been observed worldwide. Although their definitive role as vectors of infectious agents has not yet been demonstrated, bed bugs have a direct effect on human health through dermatological reactions to their bites and psychological disorders linked to domestic infestations. In this study, the effectiveness of using MALDI-TOF MS to correctly identify these two bed bug species at immature stages was assessed, as well as it effectiveness as discriminating between the immature stages (IS) of C.
