Abstract

A previously unknown bark beetle species, Cryphalus eriobotryae sp. nov. Johnson, 2019 has emerged as a lethal pest of loquat (Eriobotrya japonica) in China. The description of new species has been provided. The new species is distinguished from the other Cryphalus by the weakly aciculate frons, by the antennae, with unevenly spaced procurved sutures, by the short pronotal disc, with hair-like setae, and by the widely spaced mesocoxae. The survey of plantation records from around Suzhou suggests that this beetle was introduced from another area not long before 2017. In the surveyed loquat plantation in 2018, 20–90% of trees showed signs of infestation, and 5% were killed in 2018, resulting in the death of over 1000 trees. Outbreaks of the apparently loquat-specific Cryphalus eriobotryae can be diagnosed by hundreds of cankers on the trunk, and wilted foliage. This pest is of concern as a loquat plantation pest and as a pest of fruit production and ornamental trees within Suzhou, and globally. View Full-Text
