What the paper covers
Confirms nudivirus infection in Palauan CRB-G using molecular, microscopy and experimental evidence, and compares isolates.
Read it in context
Infection and injected larvae do not themselves establish population suppression in Hawaiʻi.
Study setting & findings
Palau · Field sampling and laboratory virus comparisons
More than 75% of trapped adults from both haplotypes were PCR-positive. Microscopy and laboratory work supported active infection; the tested virus isolates differed in laboratory performance.
