- Abstract:
- ... Vector-borne diseases are considered public health concerns. As vaccines for some of these diseases are not available or still have serious restrictions, the vector control is an important strategy. Aedes aegypti mosquitoes can transmit dengue, yellow fever, chikungunya and Zika viruses. Chemical compounds are used to control A. aegypti populations which are usually toxic to non-target organisms ...

- Abstract:
- ... An integral part to integrated mosquito management is to ensure chemical products used for area-wide control are effective against a susceptible population of mosquitoes. Prior to conducting an intervention trial using an insect growth regulator, pyriproxyfen, in South Texas to control Aedes aegypti, we conducted a larval bioassay to evaluate baseline levels of susceptibility. We used seven ...

- Abstract:
- ... Aedes aegypti, as one of the vectors transmitting several arboviruses, is the main target in mosquito control programs. Permethrin is used to control mosquitoes and Aedes aegypti get exposed due to its overuse and are now resistant. The increasing percentage of permethrin resistant Aedes aegypti has become an important issue around the world and the potential influence on vectorial capacity needs ...

- Abstract:
- ... Rapid spread of vector borne diseases, especially through mosquitoes is in alarming rise worldwide. Among mosquitoes, Aedes aegypti is a major vector transmitting arboviruses such as dengue and zika to human population. The ineffectiveness of control measures against these arboviruses has necessitated alternate strategies to curb disease transmission. Recent studies show that symbiotic bacteria ...

In insects, this technique is often applied through the delivery of dsRNA. In the adult female Aedes aegypti, a main vector of human‐infecting arboviruses, efficiency of gene silencing following dsRNA injection varies greatly according to targeted genes. Difficult ...
