A record of <em>Baculovirus penaei</em> from <em>Penaeus marginatus</em> Randall in Hawaii.

This article reports the occurrence of B. penaei in an additional host species, Penaeus marginatus Randall, and geographical area, Hawaii. Penaeus marginatus or Opai Lolo is the only member of the genus Penaeus indigenous to the Hawaiian Islands. Additional juvenile (01 to 4-0 g) P. marginatus were collected from the Kuliouou tidal flats from January to March 1984. These shrimp were held in aquaria for 7-10 days prior to examination. Shrimp were sacrificed by injection and immersion in Davidson&#39;s fixative, and after 24 h transferred to 50% ethanol for storage. Preserved hepatopancreata were processed for routine histopathology and stained with haematoxylin and eosin.
