Indirect transfer of pyriproxyfen to European honeybees via an autodissemination approach.
The frequency of arboviral disease epidemics is increasing and vector control remains the primary mechanism to limit arboviral transmission. Container inhabiting mosquitoes such as Aedes albopictus and Aedes aegypti are the primary vectors of dengue, chikungunya, and Zika viruses. Current vector con...

The frequency of arboviral disease epidemics is increasing and vector control remains the primary mechanism to limit arboviral transmission.
