This study aimed to identify soft scale insect species in five provinces (Ağrı, Bitlis, Hakkari, Iğdır and Van) in Eastern Anatolia. Species of the family Coccidae were collected from natural and cultivated plants between 2005 and 2008. In total, 31 species in 17 genera were found, including fifteen new species records for the Turkish scale insect fauna, namely: Didesmococcus unifasciatus, Eulecanium caraganae, Eulecanium ficiphilum, Lecanopsis subterranea, Lecanopsis taurica, Pulvinaria tremulae, Rhizopulvinaria armeniaca, Rhizopulvinaria dianthi, Rhizopulvinaria grandicula, Rhizopulvinaria hissarica, Rhizopulvinaria megriensis, Rhizopulvinaria turkmenica, Rhizopulvinaria variabilis, Rhodococcus turanicus and Vittacoccus longicornis .

Six new species of Newsteadia are described from the Nearctic and Neotropic Regions. A key is presented for the identification of 10 species currently included in the genus from these regions. The number of species in the genus worldwide is 37. A modified concept of the genus is presented and some new characters are given as diagnostic of the genus. The zoogeography of the genus is discussed.

Adult females of nine new species of Newsteadia ortheziids are described and detailed redescriptions are provided for the four species previously known from the Afrotropical Region including N. gomyi Richard, N. mauritiana Mamet, N. montana Mamet and N. wacri Strickland. A key is presented for the 13 species known to occur in the area and a detailed discussion is presented on the homology of the wax plates that cover the body of these fascinating scale insects.

The scale insect fauna of Romania is poorly known. Based on bibliographic sources and on collections made by the authors a complete checklist is presented. The number of scale insect species presented here from Romania is the following: 178 from outdoor and 29 species from indoor and greenhouse condition. The outdoor species belong to 9 families and 4 families for indoor species. The most numerous outdoor families were: Pseudococcidae (67 species), Coccidae (42 species), Diaspididae (37 species) and Eriococcidae (16 species). Most of the indoor species belong to: Diaspididae (20 species).The present paper contains data of 5 families and 28 species with collecting places, recording data.Three species were new for the scale insect fauna of the country: Spilococcus nanae Schmutterer, 1957, Spinococcus calluneti (Lindinger, 1912) and Rhizoecus albidus , Goux, 1936.

Planococcus citri (Risso, 1813) and Planococcus ficus (Signoret, 1875) (Hemiptera: Pseudococcidae) are important polyphagous pests species. Their high degree of morphological similarity in male and larval stage makes them difficult to distinguish. The aim of the study was to find a simple and fast PCR-based method to separate these two mealybug species. Thanks to the use of a short DNA extraction method and species-specific primer pairs, P. citri and P. ficus can be distinguished at any developmental stages within three hours.

A survey of scale insects was carried out in Ankara, in Middle Anatolia, Turkey from 2001 to 2003. Twenty-three species belonging to 5 families were recorded. Eleven of these species are new record for Turkey, namely; Exaeretopus agropyri (Hadzibejli), Exaeretopus formiceticola Newstead, Exaeretopus tritici Williams, Chortinaspis subterraneus (Lindinger), Diaspidiotus elaeagni (Borchsenius), Diaspidiotus sulci Balachowsky, Rhizaspidiotus canariensis (Lindinger), Acanthococcus devoniensis (Green), Acanthococcus tavignani Goux, Acanthococcus variabilis Goux, Neomargarodes festucae Archangelskaya and Porphyrophora minuta Borchsenius.

The maximum emergence (eclosion) of the males of P. pentagona occurred at 10.00–14.00 hours. The emergence started at temperatures above 11 °C. The maximum flight of males to pheromone traps occurred between 16.00 and 20.00 hours in days with sunshine. On days with clouds the flight already started at 10.00 hours. Intensive flight activity of males started at temperatures higher than 18 °C. The asynchrony between hatching time and flight time on sunny days could cause high mortality of the males before mating. The daily rhythm of flight was determined mainly by the light intensity. The flight was inhibited by wind speeds higher than 2 m/sec.

Sixty three scale insect species are reported from the Mezőföld area (Hungary), a mosaic area of predominantly intensive agricultural land and scattered grassland and forested areas. In comparison, from the Kőrös-Maros National Park, dominated by natural grassland areas, only 31 species were reported. From the Mezőföld data 4 species were new for the Hungarian fauna and almost all species from Mezőföld were new for the given locality. The Mezőföld fauna could be characterised by more rare species and a lower Global Frequency Value (=higher level of species rarity), suggesting a higher overall conservation value. Scale insect species numbers show a strong negative correlation with the ratio of woody plantations. There was an overwhelming presence of a steppic scale insect species in grassland assemblages, and impoverished woody fauna of the studied wooded areas. However, there was no correlation with plant species number, with the area of natural vegetation, or with the area of loess steppe patches, which shows that the original loess step fauna is impoverished, heavily disturbed. In summary we can say, that the Mezőföld loess scale insect fauna is relatively poor, could be characterised by widely distributed, mezophilous, common species. However, it also has several important steppic elements, and therefore deserves protection.
