Records of two species of the family Anisopodidae from Portugal are presented. Sylvicola punctatus is new to the Portuguese fauna.
New data is provided on 13 species of Limoniidae, which are rare to Poland. Three species: Hexatoma (Eriocera) chirothecata (Scopoli, 1763), Hoplolabis (Eurasicea) idiophallus (Savchenko, 1973) and Metalimnobia (M.) tenua Savchenko, 1976 are recorded for the first time in Poland.
This short note deals with the two faunistical records of Acrocera orbiculus and Ogcodes zonatus (Acroceridae) in Van Province and in Turkey.
This study was carried out between 2009 and 2011 in the Inner West Anatolia region (Afyonkarahisar, Kütahya and Uşak). It was determined that the collected species belonged to eight subfamilies, 21 genera and 54 species. Neurigona suturalis is a new record for Turkey and the other 53 species are new records for the Inner West Anatolia.
Three new Diptera species collected from different provinces of Turkey have been recorded for the first time from Turkey: Otites lamed (Schrank, 1781) (Ulidiidae), Chamaepsila homochroa Friedberg & Shatalkin, 2008 (Psilidae), and Cylindromyia rubida (Loew, 1854) (Tachinidae).

Orange wheat blossom midge, Sitodiplosis mosellana (Géhin) (Diptera: Cecidomyiidae), is a major economic pest of wheat ( Triticum aestivum Linnaeus). Here, we review its general biology, history of global spread, economic impact, and methods available to manage its populations. Outbreaks have been reported across the Northern Hemisphere, including in China, Japan, the European Union, the United Kingdom, the United States of America, and Canada. Predators and parasitoids can help attenuate these outbreaks, but control has relied mainly on use of foliar insecticides. Wheat cultivars with resistance to midge conferred by the Sm1 gene became commercially available in 2010 and increasingly are grown to manage midge populations. Forecasting models have been developed in different countries to predict wheat midge populations in an effort to mitigate the degree of economic damage by supporting wheat cultivar selection and to optimise the timing of insecticide applications in conventional wheat production systems. Conservation of natural enemies, insecticides, resistant cultivars, and models combine to form effective integrated pest management programmes for midge, illustrated for Canada with a decision-making flowchart. Future work is needed to address the likely development of midge biotypes with resistance to the Sm1 gene and insecticides currently in use.
[Journal: Entomologisk Tidskrift]. First records of twenty-three gall midge species in Denmark are reported: Asphondylia
ervi Rübsaamen, Contarinia acetosellae Rübsaamen, C. viburnorum Kieffer, Dasineura
astragalorum (Kieffer), D. fructum (Rübsaamen), D. harrisoni (Bagnall), D. lotharingiae
(Kieffer), D. papaveris (Winnertz), D. saxifragae (Kieffer), D. traili (Kieffer), Herbomyia
robusta Möhn, Jaapiella chelidonii Fedotova, Lasioptera arundinis Schiner, L.
calamagrostidis Rübsaamen, Mayetiola festucae Ertel, M. phalaris Barnes, M. ventricola
(Rübsaamen), Mycodiplosis coniophaga (Winnertz), Parallelodiplosis galliperda (Löw),
Piceacecis abietiperda (Henschel), Rabdophaga strobilina (Bremi), Taxomyia taxi (Inchbald)
and a probably undescribed species of Contarinia Rondani. Thus, 363 fully identified
gall midge species are now documented from Denmark along with 25 species, which have
been identified to genus level only. The species number per subfamily is 335 Cecidomyiinae
(311 fully identified and 24 identified to the genus level only), 0 Winnertziinae
and 14 Porricondyliinae (13 fully identified and one identified to the genus level only), 24
Micromyinae and 15 Lestremiinae.
