Interpretive Summary:

Technical Abstract: Capsid proteins have been shown to be a suitable target for phylogenetic studies in other insect viruses. A new insect infecting virus, isolated from the glassy-winged sharpshooter, GWSS, thus named, Homalodisca Coagulata Virus-1 (HoCV-1) demonstrated genetic relatedness to members within the Dicistroviridae, and appears to form a new clade within the newly recognized genus Cripavirus, “Cricket-Paralysis-like viruses”. Structural analysis of the HoCV-1 capsid protein indicated the presence of four domains with significant structural homology with previously established Cripavirus crystalline structures. HoCV-1 was found to increase sharpshooter mortality by ~20%, and was infective through microinjection, spraying, and bathing of insects with crude viral inoculum.
