Abstract

Summary The trypanosomatid flagellates of the genus Phytomonas were found in the salivary glands and gut of the invasive western conifer seed bug Leptoglossus occidentalis (Hemiptera, Coreidae) in Crimea. The parasites were isolated into axenic culture and identified by phylogenetic analysis based on the 18S rRNA and gGAPDH genes as P. serpens . Previously, all isolates of this species have been obtained in Brazil, from either tomato fruits or their pest bugs Phthia picta (Hemiptera, Coreidae). We investigated the morphology of trypanosomatids from the new isolate in the host bug, laboratory culture, and experimentally infected tomato fruits using light and transmission electron microscopy. We propose hypothetical scenarios of L. occidentalis involvement in the life cycle of P. serpens in the territory, which is new for both species.

一个令人困惑的发现:在克里米亚西部针叶树种子虫Leptoglossus occidentalis的巴西番茄寄生虫Phytomonas serpens

摘要在克里米亚入侵的西部针叶树种子虫西方细舌虫(Leptoglossus occidentalis，半翅目，蠓科)的唾液腺和肠道中发现了植单胞菌属的锥虫鞭毛虫。通过18S rRNA和gGAPDH基因的系统发育分析，鉴定为P. serpens。以前，该物种的所有分离株都是在巴西从番茄果实或其害虫picthia picta(半翅目，Coreidae)中获得的。利用光镜和透射电镜对新分离的锥虫虫在宿主虫、实验室培养物和实验感染番茄果实中的形态进行了研究。我们提出了西方l.s occidentalis参与P. serpens在领土上的生命周期的假设情景，这对两个物种来说都是新的。

期刊介绍： Protistology is one of the five "organism-oriented" journals for researchers of protistan material. The Journal publishes manuscripts on the whole spectrum of lower Eukaryote cells including protozoans, lower algae and lower fungi. Protistology publishes original papers (experimental and theoretical contributions), full-size reviews, short topical reviews (which are supposed to be somewhat "provocative" for setting up new hypotheses), rapid short communications, book reviews, symposia materials, historical materials, obituary notices on famous scientists, letters to the Editor, comments on and replies to published papers. Chronicles will present information about past and future scientific meetings, conferences, etc. THE PECULIARITIES OF THE JOURNAL - reviews, overviews and theoretical manuscripts on systematics, phylogeny, evolution and ecology of protists are favourably accepted - the manuscripts on multicellular organisms concerning their phylogenetic and taxonomic relationships with protists are also accepted - the size of manuscripts is usually not limited
