Fennica 10: 7-28. 27 species of Chloropinae are recorded from Finland, 7 of them for the first time. 14 species are recorded from Karelia and 3 from the Kola Peninsula, all for the first time. The distributions of all species in the territory investigated are mapped. The type specimens of Lasiosina parvipennis Duda are examined and a lectotype designated. A key to the genera and species of Chloropinae, except for species of the genera Chlorops and Meromyza, is given. The distribution in Finland of all species of Chloropinae, including the genera Chlorops and Meromyza, is dis­ cussed. The fauna of Chloropinae of Finland is compared with the faunas of St. Petersburg Province, Estonia and Yakutia. Emilia P.

Niepodległości 10, 61-875 Poznań, Poland Received: 27 March 2020 Accepted: 14 May 2020 Abstract The article presents the results of 3-year field studies, whose purpose was to assess the impact of maize sowing method, type of cultivar and NP fertiliser sowing method on the health of maize plants. Changing weather conditions during the study years significantly differentiated the percentage of maize plants damaged by pests and affected by diseases. The positive effect of the row method of NP fertiliser application in maize cultivation not only reduced plant infestation by Fusarium diseases, but also reduced Frit fly Oscinella( frit L.) pressure. The “stay-green” hybrid was characterized by a significantly lower susceptibility to feeding of the European corn borer (Ostrinia nubilalis Hbn.) compared to the traditional cultivar. Sowing maize of the traditional cultivar using the direct sowing system increased damage to plants caused by Frit fry larvae (Oscinella frit L.) compared to sowing into soil cultivated in a traditional way.

A list of the 24 species in 16 genera and two subfamilies collected in Kuril Islands is given. Twenty-two species are firstly recorded from Iturup Island. Chlorops mugivorus Nishijma et Kanmiya, 1975 and Rhodesiella tripectinata Kanmiya, 1983 are recorded for the fauna of Russia for the first time. Moreover, Thaumatomyia trifasciata (Zetterstedt, 1848) is firstly recorded from Kuril Islands (Paramushir). Key words: Diptera, Chloropidae, fauna, new records, Kuril Islands, Russia. Э. П. Нарчук. Новые данные о злаковых мухах (Diptera: Chloropidae) острова Итуруп (Россия, Курильские острова) // Дальневосточный энтомолог. 2016. N 318. С. 20-24. Резюме. Приведен список собранных на Курильских островах 24 видов злаковых мух из 16 родов и двух подсемейств. Впервые для острова Итуруп указываются 22 вида. Chlorops mugivorus Nishijma et Kanmiya, 1975 и Rhodesiella tripectinata Kanmiya, 1983 впервые отмечаются в фауне России. Впервые для Курил (о-в Парамушир) указывается Thaumatomyia trifasciata (Zetterstedt, 1848). The Chloropidae is a family of Cyclorrhaphous flies with great taxonomic diversity. Most of species have phytophagous larvae developing in shoots or in inflorescences of grasses and sedges (Poaceae and Cyperaceae). Many species have saprophagous larvae feed on decaying tissues of plants damaged by other insects, in fungi, in rotting wood with mycelia. Some species have carnivorous or parasitic larvae developing in egg cocoons of spider, egg pod of Acrididae and Mantidae, some species are predators of root aphids.

  • Distribution of Oscinellinae (Diptera: Chloropidae) in the Danish Landscape Lise Brunberg Nielsen
    Distribution of Oscinellinae (Diptera: Chloropidae) in the Danish landscape Lise Brunberg Nielsen Nielsen, Lise Brunberg: Distribution of Oscinellinae (Diptera: Chloropidae) in the Danish Landscape. Ent. Meddr 82: 39-62, Copenhagen, Denmark, 2014. ISSN 0013-8851 Abstract About 29,700 Oscinellinae were collected by means of sweep net, water traps and pitfalls in a variety of uncultivated habitats in Denmark mainly in Jutland. So far 75 species belonging to 21 genera are re­ corded from Denmark. Eleven species are new to the Danish fauna. Morphological details of Aphanotrigonum brachypterum, A. hungaricum, A. nigripes, Conioscinella gallarum, lncertella albipalpis, I. nigrifrons, I. kerteszi, I. scotica and Oscinella angustipennis are presented. The distribu­ tion of Oscinellinae in the Danish landscape is discussed. In Denmark, farmland dominates, so the two most abundant Oscinellarspecies of ara­ ble land, Oscinella frit and 0. vastator, are also predominant in most nat­ ural habitats. Small and larger uncultivated areas, however, making up only 25 % of the Danish landscape, contain a rich fauna of Oscinel­ lines. The advantage of different sampling methods combined is demonstrated. Sammendrag Fordelingen af fritf1uer (Diptera: Chloropidae) i det danske landskab.

Al-Saffar Iraq Natural History Research Center and Museum, University of Baghdad, Baghdad, Iraq Corresponding author: [email protected] Received Date:27 March 2018 Accepted Date:30 April 2018 ABSTRACT The aim of this study is to survey and make to revision the genera and species of Chloropidae fauna of Iraq. The investigation showed four species belonging four genera, which belongs to two subfamilies, and one unidentified species belonging to the genus Elachiptera Maquart, The specimens were compared with stored insects at Department of Entomology and invertebrates, Iraq Natural History Research Center and Museum. Key words: Brachycera, Chloropidae, Diptera, Eye fly, Grass fly, Iraq. INTRODUCTION The family Chloropidae Schoenher,1840 (frit flies, grass flies or eye flies) belongs to super family Carnoidea. It has four subfamilies: Chloropinae, Oscinellinae, Rhodesiellinae, and Siphonellpsinae (Brues et al.,1954). The members of Chloropidae are worldwide distribution or cosmopolitan and are found in all Zoogeographical regions except Antarctica; they are about 3000 described species under 200 genera (Sabrosky,1989; Canzoneri, et al., 1995; Nartshuk, 2012; Bazyar et al., 2015). The grass flies are also found in marshes, vegetation areas, forests; the members of the family are phytophagous. Some species as a gall maker of stems likes Lipara lucens Meigen, 1830 on Phragmites australis (Poaceae) are affected on the morphological tissue (Van de Vyvere and De Bruyn, 1988); and many larvae feed and developed flower heads, shoots and seeds of Poaceae and some feed on the stems of cereals, thus affected of economic production (Alford,1999; Karpa, 2001;Petrova et al., 2013).

Wiesenborn1 ABSTRACT.—Phoradendron juniperinum (Viscaceae) is a dioecious, parasitic plant of juniper trees ( Juniperus [Cupressaceae]) that occurs from eastern California to New Mexico and into northern Mexico. The species produces minute, spherical flowers during early summer. Dioecious flowering requires pollinating insects to carry pollen from male to female plants. I investigated the pollination of P. juniperinum parasitizing Juniperus osteosperma trees in the Cerbat Mountains in western Arizona during June–July 2016. I examined pollen from male flowers, aspirated insects from female flowers, counted conspecific pollen grains on insects, and estimated floral constancy from proportions of conspecific pollen in pollen loads.

  • Chloropidae (Diptera) of Turkey with Descriptions of New Species and New Records
    ISRAEL JOURNAL OF ENTOMOLOGY, Vol. 41–42, 2011–2012, pp. 115–144 Chloropidae (Diptera) of Turkey with descriptions of new species and new records EMILIA P. NARTSHUK Zoological Institute of the Russian Academy of Sciences, Universitetskaya nab 1, 199034 St. Petersburg. E-mail: [email protected] ABSTRACT A list of Chloropidae from Turkey is provided, containing 64 species from 31 genera and 4 subfamilies. Three species are described as new. Two additional species were only identified to genus level. Twelve species are listed based only on literature data. Most species (40) are recorded from Turkey for the first time. KEYWORDS: Diptera, Chloropidae, Asia Minor, Turkey, new species, new faunistic data INTRODUCTION Grass flies of the family Chloropidae (Diptera, Cyclorrhapha) of Turkey are insuf- ficiently studied, and only 21 species have been recorded to date. Loew (1858) de- scribed 3 species: Oscinis brevirostris (now Aphanotrigonum cinctellum (Zetterstedt)), O. marginata (now Polyodaspis ruficornis (Macquart)) and Crassiseta megaspis (now in Elachiptera). He also cited Constantinopolis as type locality for the two former spe- cies and Asia minor for the latter species. Becker (1912) described Chlorops pallidior from Asia Minor. Duda (1932-1933) recorded Oscinimorpha albisetosa Duda, Chlo- rops fasciatus Meigen and Thaumatomyia sulcifrons Becker from Asia minor, Lodos (1957) recorded Oscinella frit (Linnaeus) as Scatopse nigra, but his drawings of the fly, including its wing, beyond question refer to O. frit. This species was mentioned by Özer (1976) as well. Lessman (1962), who studied pests of cones of Ceder libani, found larvae of a fly, which he did not name (see comments below under Hapleginella laevi- frons (Loew, 1858)).
