In this video, we describe the larval contact assay to evaluate the toxicity of the dopamine receptor antagonist amitriptyline on the third instar stage larvae of mosquitoes, known vectors of several human infectious diseases. Assessing the larval mortality upon incubation with different amitriptyline concentrations over different time intervals helps determine its lethal concentration 50.

Aedes aegypti mosquitoes infected with Wolbachia are being released into natural populations to suppress the transmission of arboviruses. We describe methods to rear Ae. aegypti with Wolbachia infections in the laboratory for experiments and field release, taking precautions to minimize laboratory adaptation and selection.

Numerous novel virus-like sequences have been found in mosquitoes due to the extensive use of sequencing technologies. We provide an effective procedure for isolating and amplifying viruses using vertebrate and mosquito cell lines, which might serve as the basis for future studies on mosquito-associated viruses, including mosquito-borne and mosquito-specific viruses.

In this candid interview, Anthony A. James explains how mosquito genetics can be exploited to control malaria and dengue transmission. Population replacement strategy, the idea that transgenic mosquitoes can be released into the wild to control disease transmission, is introduced as well as the concept of genetic drive and the design criterion for an effective genetic drive system. The ethical considerations of releasing genetically-modified organisms into the wild are also discussed.
FAQs
Survival can vary between developmental stages because environmental stressors, limited resources, pathogens, predators, and insecticides may disrupt development, feeding, reproduction, or nervous-system function differently. Separating larvae, juveniles, and adults in mortality assessments helps identify when populations are most vulnerable. This improves interpretation of population dynamics and clarifies which processes may influence later mosquito abundance.
Defined temperature, humidity, and exposure conditions make survival comparisons more meaningful by reducing uncertainty about the environment surrounding each mosquito group. These conditions help researchers determine whether mortality reflects a tested stressor or differences in habitat quality. Controlled comparisons are particularly useful when evaluating environmental change or assessing the effects of mosquito-control interventions.
Insecticide-related mortality provides evidence about how effectively an intervention affects mosquito survival and supports insecticide-resistance studies. If survival differs under a defined exposure, researchers can evaluate the relationship between the treatment and population response. Such measurements help distinguish effective control from reduced susceptibility and guide interpretation of how insecticides influence disease-vector populations.
Researchers measure mortality by tracking survival in mosquito groups exposed to defined environmental or treatment conditions, while considering the life stage being studied. Recording outcomes across temperature, humidity, or exposure settings allows comparisons among conditions. The resulting survival data can be used to evaluate habitat quality, environmental stress, or the effectiveness of a mosquito-control intervention.
Mortality data help evaluate whether control interventions reduce mosquito survival sufficiently to influence population abundance. When combined with information about environmental conditions and life stage, these measurements support risk assessment for mosquito-borne diseases and help guide insecticide-resistance studies. The findings provide a basis for comparing interventions and identifying environmental factors that may affect control outcomes.
Changes in mosquito survival can indicate how altered environmental conditions affect population dynamics and habitat quality. Because mosquitoes interact with predators, pathogens, resources, and broader ecological communities, mortality patterns may also help clarify changes beyond the mosquito population itself. These observations support environmental assessments that connect vector abundance with wider ecosystem interactions.
