Symptoms and Yield Loss Caused by Rice Stripe Mosaic Virus Siping Chen, Weilin Li, Xiuqin Huang, Biao Chen, Tong Zhang and Guohui Zhou*
Chen et al. Virology Journal (2019) 16:145 https://doi.org/10.1186/s12985-019-1240-7 RESEARCH Open Access Symptoms and yield loss caused by rice stripe mosaic virus Siping Chen, Weilin Li, Xiuqin Huang, Biao Chen, Tong Zhang and Guohui Zhou* Abstract Background: Rice stripe mosaic virus (RSMV) is a tentative new Cytorhabdovirus species in family Rhabdoviridae transmitted by the leafhopper Recilia dorsalis. Although the virus was first detected in southern China in 2015, few studies have investigated rice symptoms and yield losses caused by RSMV infection. Methods: In this study, we observed and systematically compared symptoms of three virally infected, representative varieties of indica,hybridandjaponica rice and determined the yield parameters of the artificially inoculated plants. Results: The three RSMV-infected cultivated rice varieties exhibited slight dwarfing, striped mosaicism, stiff, crinkled or even twisted leaves, an increased number of tillers, delayed heading, cluster-shaped shortening of panicles and mostly unfilled grains. Slight differences in symptom occurrence time were observed under different environmental conditions. For example, mosaic symptoms appeared earlier and crinkling symptoms appeared later, with both symptoms later receding in some infected plants. Yield losses due to RSMV also differed among varieties. The most serious yield reduction was experienced by indica rice (cv. Meixiangzhan), followed by hybrid indica rice (cv. Wuyou 1179) and then japonica (cv. Nipponbare). Single panicle weight, seed setting rate and 1000-kernel weight were reduced in the three infected varieties compared with healthy plants—by 85.42, 94.85 and 31.56% in Meixiangzhan; 52.43, 53.06 and 25.65% in Wuyou 1179 and 25.53, 49.32 and 23.86% in Nipponbare, respectively. -

The genus Parasogata Zhou, Yang & Chen, 2018 is here reported from India represented by the new species Parasogata sexpartita sp. nov. collected in a recent exploration and survey of delphacids from Nagaland in northeastern India. A second species of Eoeurysa Muir, 1913 from India, the new species Eoeurysa sagittaria sp. nov., was found in Rampur, Una, Himachal Pradesh. Both new species are described with illustrations, and a molecular identification is given with the mtCOI gene sequence. A modified key to species of the genera is also provided. Keywords.

Dokdo is a volcanic island created by a volcanic eruption that promoted the formation of Ulleungdo (located in the East sea), which is ~87.525 km away from Dokdo. Dokdo is an important island because of geopolitics; however, because of certain investigation barriers such as weather and time constraints, the awareness of its insect fauna is less compared to that of Ulleungdo. Dokdo’s insect fauna was obtained as 10 orders, 74 families, and 165 species until 2017; subsequently, from 2018 to 2019, 23 unrecorded species were discovered via an insect survey. -

Acta Musei Moraviae, Scientiae biologicae (Brno) 90: 195–207. – Leafhoppers, planthoppers and psyllids light-trapped into streetlamps were examined at two sites in complex ruderal habitats (fields, annual and perennial ruderal vegetation, scrub with ruderal and alien species) in Slatina, on the periphery of the city of Brno in South Moravia. A total of 1628 specimens and 61 species were found. Among the dominant species were Empoasca vitis, E. decipiens, E. pteridis, Macrosteles laevis, Psammotettix alienus, Javesella pellucida, Laodelphax striatella, Zyginidia pullula, Kybos lindbergi, and Edwardsiana rosae. Noteworthy are records of Kybos calyculus and Oncopsis appendiculata (both new for the Czech Republic), several rare species living in dry ruderal grassland (Recilia horvathi, Macrosteles quadripunctulatus, Balclutha saltuella), and hygrophilous species caught on dispersal flight (Pentastiridius leporinus, Calamotettix taeniatus, Cicadula placida, Limotettix striola, and Paramesus major).

Introduction Leafhoppers (Cicadomorpha), planthoppers (Fulgoromorpha) and psyllids (Sternorrhyncha: Psylloidea) are phytophagous insects belonging to the order Hemiptera. They suck plant sap, mostly from phloem vessels, some groups feed on xylem or mesophyll tissues. -

E-mail: [email protected] Abstract The new genus Aethodelphax gen. nov. is described to include one new species, Aethodelphax prairianus sp. nov. and 7 species transferred from Delphacodes: Aethodelphax aetocephalus (Beamer, 1948), comb. nov., A. alatus (Beamer, 1948), comb. nov., A. caninus (Beamer, 1947), comb. nov., A. concavus (Beamer, 1948), comb. nov., A. megadontus (Beamer, 1951), comb. nov., A. paraparvulus (Beamer, 1948), comb. nov., and A. sagittatus (Beamer, 1947), comb. nov. A diagnosis for all species, illustrations and an identification key is provided. All species are found in the midwestern and southeastern states of the U.S., except A. caninus which is recorded from Arizona and New Mexico, and are all associated with native grasslands. Key words: Delphacidae, Fulgoroidea, Delphacodes, new genus, new species Introduction This study reports a new and locally common species of Delphacidae that appears to be restricted to bluestem grasses, Andropogon spp., in native tallgrass prairies. It is superficially similar to the widespread bluestem special- ist Muirodelphax parvula (Ball) (see Hamilton & Kwon 2010) and has probably been overlooked until now in grassland surveys. -

Zusammenfassung Die vorliegende Arbeit hat sich zum Ziel gesetzt, den Populationskomplex der hawai’ischen Höhlenzikade Oliarus polyphemus als Modellsystem für das Stu- dium schneller Artenbildungsprozesse zu erschließen. Dazu wurde ein theoretischer Rahmen aus Konzepten und daraus abgeleiteten Hypothesen zur Interpretation be- kannter Fakten und Erhebung neuer Daten entwickelt. Im Laufe der Studie wurde zur Erfassung geografischer Muster ein GIS (Geographical Information System) erstellt, das durch Einbeziehung der historischen Geologie eine präzise zeitliche Einordnung von Prozessen der Habitatsukzession erlaubt. Die Muster der biologi- schen Differenzierung der Populationen wurden durch morphometrische, etho- metrische (bioakustische) und molekulargenetische Methoden erfasst. -

Biodiversity Data Journal 9: e62011. https://doi.org/10.3897/BDJ.9.e62011 Abstract Background Dokdo, a group of islands near the East Coast of South Korea, comprises 89 small islands. These volcanic islands were created by an eruption that also led to the formation of the Ulleungdo Islands (located in the East Sea), which are approximately 87.525 km away from Dokdo. Dokdo is important for geopolitical reasons; however, because of certain barriers to investigation, such as weather and time constraints, knowledge of its insect fauna is limited compared to that of Ulleungdo. Until 2017, insect fauna on Dokdo included 10 orders, 74 families, 165 species and 23 undetermined species; subsequently, from 2018 to 2019, we discovered 23 previously unrecorded species and three undetermined species via an insect survey.
