Preimaginal development of Aedes aegypti L. (Diptera: Culicidae) in brackish water gives rise to adult mosquitoes with thicker cuticles and greater insecticide resistance

Medical and Veterinary Entomology, EarlyView.
The principal arboviral vector Aedes aegypti can develop in coastal brackish water field habitats (0.5–15 g/L salt) with larvae possessing thicker cuticles and greater resistance to the larvicide Temephos. Females emerging from brackish water‐developing preimaginal stages are now shown to have thicker and remodelled leg and abdominal cuticles and ...

Ingestion of attractive toxic sugar baits containing ivermectin before and after blood feeding affects the biology and reproduction of Aedes aegypti (Diptera: Culicidae)

Medical and Veterinary Entomology, EarlyView.
Attractive toxic sugar bait containing ivermectin (ATSB‐IVM) ingestion markedly reduced blood feeding, survival, oviposition, egg production and larval hatching, with the strongest effects when baits were ingested before blood feeding. Timing of ingestion (48–96 h before or after blood feeding) shaped sublethal impacts across the first and second ...

Effect of blood meals and mating on biodemographic characteristics of Aedes albopictus

Physiological Entomology, EarlyView.
Lifespan did not differ between virgin and mated males and females. The number of blood meals (one and two) significantly reduced adult lifespan compared with those with no blood meal. The effect of the second blood meal doubled females' egg production and their reproductive output.

Photodegradation of commercial insect repellents containing DEET and IR‐3535 under ultraviolet light associated or not with chemical ultraviolet filters evaluated by Raman spectroscopy

Photochemistry and Photobiology, EarlyView.
This study evaluated the photodegradation of commercial insect repellents containing DEET and IR‐3535 under UV‐A and UV‐B irradiation using Raman spectroscopy. Pure DEET and IR‐3535 showed intrinsic photostability, whereas DEET diluted in ethanol and a commercial DEET‐based formulation exhibited significant spectral changes after UV exposure.

Donor Dilemma: A National Simulation‐Based Case Curriculum for Teaching Donor Call Decision‐Making in Infectious Diseases Trainees

Transplant Infectious Disease, EarlyView.
An asynchronous donor‐call case‐based progressive disclosure curriculum was feasible and valued across diverse ID and TID training programs. ID and TID trainees reported improved confidence in their clinical reasoning and ability to evaluate donor‐suitability, supporting this educational approach to address a training gap.

Early Warning Systems and Emergency Declarations During Brazil's Largest Dengue Outbreak

Tropical Medicine &International Health, EarlyView.
ABSTRACT Objectives Early warning systems (EWSs) are essential for alert, detection, and response to potential public health emergencies. Brazil's 2024 dengue epidemic, the largest ever recorded, offers a critical case for assessing correspondence between timely epidemic risk detection and health governance responsiveness.

Korat‐Scrub Typhus Score: A Clinical Tool for Predicting Scrub Typhus in Patients With Acute Undifferentiated Febrile Illness

Tropical Medicine &International Health, EarlyView.
ABSTRACT Objective Scrub typhus is a major cause of acute undifferentiated febrile illness (AUFI) in the Asia–Pacific region. Nonspecific presentation, limited diagnostic accuracy and delayed treatment increase morbidity and mortality. This study aimed to develop a simple clinical score for early diagnosis in adults with AUFI. Methods A cross‐sectional
