The seasonal prevalence of the citrus red mite and its predators on Satsuma mandarin trees was surveyed by nakedeye observation and the beating method in three commercial groves in Shizuoka Prefecture in 2003 and 2004. Of the predators, only phytoseiid mites were caught mainly by beating, and their population dynamics were synchronized with those of the citrus red mite from June to September. Most adult females of phytoseiid mites caught by beating belonged to the species Neoseiulus californicus. Furthermore, one population of N. californicus caught from a surveyed grove showed development and oviposition on the eggs of the citrus red mite as well as the Tetranychus urticae eggs under experimental conditions. These results indicate that an indigenous population of N. californicus in conventionally controlled citrus groves in central Japan has the ability to suppress the population of P. citri on Satsuma mandarin.

In April 2023, following the annual International Committee on Taxonomy of Viruses (ICTV) ratification vote on newly proposed taxa, the phylum Negarnaviricota was amended and emended. The phylum was expanded by one new family, 14 new genera, and 140 new species. Two genera and 538 species were renamed. One species was moved, and four were abolished. This article presents the updated taxonomy of Negarnaviricota as now accepted by the ICTV.
