发生在云南与东盟边境的一种新害虫——热带拂粉蚧(同翅目:粉蚧科)

【背景】热带拂粉蚧属于粉蚧类昆虫,食性杂,是危害热带和亚热带水果、蔬菜和园林植物的重要害虫,主要随水果、苗木和交通工具等介质进行远距离传播。2014年5月,在我国云南与缅甸边境发现该虫危害草本植物马松子。【方法】在收集整理热带拂粉蚧生物学、地理学等信息的基础上,介绍了其主要形态特征、寄主、分布、生物学特性,并对该有害生物的危害和防治进行了综合分析。【结果】热带拂粉蚧雌成虫长椭圆形,触角8节,体长2.5~3.0 mm,宽1.5~2.0 mm,主要通过孤雌生殖繁殖后代,形态特征与双条拂粉蚧非常相似。我国的广东、广西、海南、云南、福建等热带地区适合该虫生存和危害,一旦入侵我国会对花卉、水果和蔬菜等造成危害,给相关产业带来损失。【结论与意义】热带拂粉蚧在我国有传播扩散的可能,加强检疫是防范该虫入侵的主要手段,生物防治是治理该虫的重要措施。

A new species and a new record of the genus Balanococcus Williams(Hemiptera:Coccoidea:Pseudococcidae) from China

A new species and a new record of the genus Balanococcus Williams are described from China.They are B.zhejiangensis sp.nov.and B.kwoni Pellizzari Danzig,2007.The new species,collected from Zhejiang,China under leaf sheath of Phyllostachys praecox,is similar to B.kwoni Pellizzari Danzig,but can be distinguished by its hind coxa inflated,and only small type of oral collar tubular ducts present on dorsal surface.A key to Chinese species of Balanococcus is given.All specimens examined are deposited in the Insect Collection of Beijing Forestry University.     

Molecular phylogeny and species recognition in the mealybug genus Ferrisia Fullaway (Hemiptera: Pseudococcidae)

Previous allozyme and DNA nucleotide sequence studies of the mealybug genus Ferrisia Fullaway (Hemiptera: Pseudococcidae), although limited, have suggested greater species diversity than is recognized by the current morphology‐based taxonomy. Here we analyse nucleotide sequence data from one mitochondrial (cytochrome oxidase I) and two nuclear (EF‐1α and 28S D₂D₃) genes and recover ten well‐supported groups that allow us to reassess the taxonomic utility of morphological characters used for species recognition. We report on previously used morphological characters for which states are highly variable within genetic groups and identify new characters (of the wax‐exuding cuticular ducts and pores) with taxonomically informative states. The widespread pest species F. virgata (Cockerell), commonly called the striped mealybug, should be diagnosed more narrowly. From samples identified as F. virgata, we recover six clades that we equate with species and that can be distinguished with the newly identified morphological characters. We determine that five of the ‘electrophoretic species' identified informally by the late Uzi Nur based on electrophoretic mobility of 20 enzymes correlate with four of our genetic groups. This matching of Nur's putative species with ours was possible only because some of Nur's slide‐mounted voucher specimens were deposited in a museum and thus available for morphological study. Species confused with F. virgata are either new to science or were placed erroneously in synonymy with F. virgata by earlier authors: they will be described elsewhere. The most important characters of the adult female for distinguishing these species from F. virgata are the positions and characteristics of minute discoidal pore(s) associated both with the ventral oral‐collar tubular ducts and with the sclerotized area surrounding each dorsal enlarged tubular duct, and the number of sizes of the ventral oral‐collar tubular ducts. In addition, we determine that adult females of F. gilli Gullan from different populations on different host plants vary substantially in the number and size of clusters of small ventral oral‐collar ducts on the body margins – features previously suspected to indicate distinct species.
