Bed bugs, leeches, and hookworm-related cutaneous larva migrans are skin infestations that are usually considered of minor importance because they produce discomfort rather than cause or transmit disease. Bed bugs have been increasing tremendously in high-income countries in recent years, causing distress to affected individuals and economic loss. Infestation by land leeches causes mainly unpleasant skin reactions, whereas infestation by aquatic leeches may be more dangerous, leading to anemia and in severe cases, to death. Cutaneous larva migrans produces an intense pruritus that can be exasperating for the patient and cause sleep disturbance. An overview is given of these three infestations with a discussion of the causative agents, transmission, clinical manifestations, diagnosis, and treatment.

Natural Resources Defense Council, 20 N Wacker Dr #1600, Chicago, IL, 60606, USA.
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.
Efficiency of MALDI-TOF MS at identifying and discriminating immature stages of cimex lectularius and cimex hemipterus bed bugs.

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.

Background: Isoxazolines inhibit γ-aminobutyric acid chloride channels in insects and acarids by binding to postsynaptic receptors. This prevents chloride influx, leading to depolarization/hyperexcitation, paralysis, and death. Here, we evaluated the potential utility of a novel isoxazoline, isocycloseram, against several urban insect pests.

Article Synopsis
- The study investigates insecticide resistance in bed bugs, specifically identifying a resistant strain in Japan with a high pyrethroid resistance ratio compared to other strains.
- Researchers sequenced the genomes of both resistant and susceptible strains, enabling them to identify 729 unique mutated transcripts related to resistance, highlighting key genes involved in the process.
- The findings suggest that targeting specific genes through genome editing could help understand the evolution of resistance and improve monitoring methods for resistance levels in bed bugs.
Barriers of persistent long-lasting insecticidal nets utilization in Northwest Ethiopia: a qualitative study.

Article Synopsis
- Malaria remains a major public health issue in Ethiopia, and while Long-Lasting Insecticidal Nets (LLINs) are effective in reducing transmission, their consistent usage is hindered by various behavioral and socio-economic factors.
- A study conducted in East Belessa District involved interviews with community members and key informants to deeply understand the challenges to LLIN use, utilizing an interpretive description approach for context analysis.
- Findings revealed three key themes: community knowledge about malaria and LLINs, perceptions of malaria risk, and various barriers—including individual, socio-cultural, and institutional factors—that affect the regular utilization of LLINs.
