Vector Disease Control International (VDCI) has a long history of aiding mosquito control efforts necessary for recovery after natural disasters like hurricanes and major floods. As waters associated with these events begin to recede, both nuisance and vector mosquito species surge in abundance and consequently play an increased role in public health. When these situations arise, state and county agencies implement emergency response plans and many rely on Federal Emergency Management Agency or private contractors for assistance in reducing mosquito populations that can alter arbovirus transmission cycles, cause intolerable stress, hamper reconstruction efforts, and disrupt normal community functions. Vector Disease Control International owns the largest fleet of fixed-wing aircraft dedicated specifically to mosquito control and has worked every major storm event since Hurricane Bonnie in 1998. This article describes the logistics and operations required for implementing VDCI's emergency management plan, including the relocation of equipment, adult mosquito surveillance, delivery of pesticides, assessment of efficacy, and filing of low-level waivers and congested-area plans with the Federal Aviation Administration.

The dengue virus (DENV) is primarily transmitted by . Investigating genes associated with mosquito susceptibility to DENV2 offers a theoretical foundation for targeted interventions to regulate or block viral replication and transmission within mosquitoes. Based on the transcriptomic analyses of the midgut and salivary glands from infected with DENV2, alongside analyses of Aag2 cell infections, 24 genes potentially related to the regulation of infection with DENV2 were selected.

Dengue fever, caused by the dengue virus (DENV), poses a significant global health challenge, particularly in tropical and subtropical regions. Recent increases in indigenous DENV cases in Europe are concerning, reflecting rising incidence linked to climate change and the spread of mosquitoes. These vectors thrive under environmental conditions like temperature and humidity, which are increasingly influenced by climate change.

Flaviviruses are arthropod-borne viruses primarily transmitted through the mosquito or genus of mosquitos. These viruses are predominantly found in tropical and subtropical regions of the world with their geographical spread predicted to increase as global temperatures continue to rise. These viruses cause a variety of diseases in humans with the most prevalent being caused by dengue, resulting in hemorrhagic fever and associated sequala.

Current arbovirus surveillance strategies in Australia involve mosquito collection, species identification, and virus detection. These processes are labour-intensive, expensive, and time-consuming and can lead to delays in reporting. Mosquito excreta has been proposed as an alternative sample type to whole mosquito collection, with potential to streamline the virus surveillance pipeline.

is of great public health concern because of its vectorial capacity to transmit various arboviruses such as Zika, yellow fever, dengue, and chikungunya. In California, its expanding geographic distribution has been unrestrained. This urgently calls for innovative tools such as the use of sterile insect technique (SIT) to strengthen invasive control.
