A protocol is developed to examine the effects of an epigenetic drug DZNep on the development, fecundity and survivorship of mosquitoes. Here we describe procedures for the aqueous exposure of DZNep to immature mosquitoes and a blood-based exposure of DZNep to adult mosquitoes in addition to measuring SAH hydrolase inhibition.

Reverse genetic approaches have proven extremely useful for determining which genes underly resistance to vector pathogens in mosquitoes. This video protocol illustrates a method used by the Dimopoulos lab to inject dsRNA into Anopheles gambiae mosquitoes, which harbor the malaria parasite. The technique manipulating the injection setup and injecting dsRNA into the thorax is illustrated.

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.
FAQs
Standardized conditions make egg-number differences more interpretable because females experience comparable opportunities to feed and lay eggs. If feeding access, oviposition conditions, or observation timing varies, measured output may reflect the setup rather than the biological factor under study. Consistency therefore supports comparisons involving genetics, nutrition, environmental conditions, pathogens, or insecticide exposure.
Egg counts provide a reproductive-output measure, but related observations can clarify what produced a difference. Recording blood-feeding status, survival, or egg development helps distinguish reduced reproduction from failure to feed, loss of the female, or altered development after egg production. This combined interpretation gives the assay greater biological context than egg number alone.
Genetic background, nutrition, environmental conditions, pathogens, and insecticides can all be examined as influences on mosquito reproduction. A fecundity assay detects their effects through changes in egg production under controlled conditions. Comparing these responses helps identify whether a factor is associated with increased or reduced reproductive output and supports broader studies of mosquito biology.
The workflow begins with individual female mosquitoes receiving a standardized blood meal, followed by placement under controlled oviposition conditions. Researchers then monitor the females for a defined period and count the eggs produced. The resulting records can be paired with feeding status, survival, or egg-development observations to support interpretation of reproductive performance.
The defined observation period establishes when egg production is assessed and makes measurements comparable across females or experimental conditions. It also prevents results from combining observations collected over inconsistent intervals. Because reproductive output may be linked with egg development or survival, clearly recording the time window helps researchers interpret what the egg count represents.
This assay is useful when researchers need to examine how reproductive output relates to mosquito biology, vector competence, population dynamics, or disease-control strategies. It can reveal reproductive effects associated with pathogens or insecticides and help evaluate how experimental conditions influence egg production. These results provide a measurable basis for studying factors that may shape mosquito populations.
