Dicranocentrus liuae sp. n. is described from the northern subtropical region of China. The new species is most similar to D. wangi Ma & Chen, 2007, but differs from it in the relatively shorter Ant. V, the 1+1 central macrochaetae on Abd. III, the number of chaetae on tenaculum, and the absence of dental spines. The systematic position of Dicranocentrus is also discussed. Present evidence, par...
چکیده پادمان یا دم فنری ها فراوان ترین بندپایان کوچک خاکزی هستند. اندازه آنها کوچک و از لحاظ طبقه بندی در گروه دهان درونیان قرار دارند. شش پایان بدون بال و دارای شاخک می باشند. اغلب گونه ها دارای فورکا در بخش عقبی شکم می باشند. در جهان حدود 7000 گونه از پادمان شرح داده شده اند. این حشرات همه جازی هستند و به غیر از چند گزارش که حاکی از این هستند پادمان آفت محصول می باشند در کل به عنوان حشرات س...
Five new eyed species of Sinella from China, respectively with 3, 3, 2, 1, 1 ommatidia on each side, are described here: S. longisensilla sp. nov., S. yui sp. nov., S. pseudobrowni sp. nov., S. sacellum sp. nov. and S. gracilis sp. nov. Clypeal chaetae and chaetae along cephalic groove exhibit differences among these species and could be used to distinguish species in Sinella and Coecobrya. A k...
Seven Australian species of the genus Drepanura are reported. Two of the seven are new and five are redescribed. The new species are: D. liuae sp. nov. and D. polychaeta sp. nov. Redescriptions are given for D. albocoerulea (Schött, 1917), D. cinquilineata Womersley, 1934, D. citricola Womersley, 1934, D. cobaltina (Schött, 1917) and D. coeruleopicta (Schött, 1917). The chaetotaxy is described ...

RNAi-based genetically engineered (GE) crops for the management of insect pests are likely to be commercialized by the end of this decade. Without a workable framework for conducting the ecological risk assessment (ERA) and a standardized ERA protocol, however, the utility of RNAi transgenic crops in pest management remains uncertain. The overall goal of this study is to assess the risks of RNA...
Two new Coecobrya species, which were newly collected in 2014, are described from China. Coecobryasanmingensis sp. n. from southeast China (Fujian) is the fourth 1+1 eyed species in the genus; it can be distinguished from other three species by the ciliate chaetae X and X2-4 on the ventral side of head, the abundant chaetae on the trochanteral organ, a large outer tooth on the unguiculus, the a...
The taxonomic status of the subgenera of Lepidocyrtus Bourlet is confused. Currently ten subgenera are recognised but their separation, using the existing set of diagnostic characters, is not clear. Collections over the last forty years have shown that species of Setogaster Salmon, originally described as a genus (Trichogaster Handschin) and currently considered a subgenus of Lepidocyrtus, are ...
