The impact of temperature and insect-specific viruses on the transmission of alphaviruses by <i>Aedes japonicus japonicus</i>.

ABSTRACT: Arthropod-borne virus (arbovirus) infections are increasing globally, and invasive mosquito species are spreading. Since the end of the last century, Aedes japonicus has continued to spread in Europe as well as in North America. Aedes japonicus is known to be able to transmit several viruses, but extensive information about the vector competence of Ae. japonicus for alphaviruses is missing. Therefore, we infected field-caught Ae. japonicus mosquitoes from Germany with different alphaviruses that occur in areas with either tropical or moderate temperatures and are clustered as arthritogenic or encephalitic alphaviruses. Additionally, we studied the influence of temperature and natural infections with insect-specific viruses (ISVs) on the vector competence of A
