Ferenc Kozár – A dedicated and prolific worker on scale insects

At the XII Meeting of the International Symposium on Scale Insect Studies, delegates and coccidologists worldwide congratulate Dr Ferenc Kozár for his work on scale insects during over 40 years of concentrated study. Ferenc is well known for his contributions to economic and taxonomic work on scale insects. He entered the Agricultural University in Budapest, Hungary, in 1962, and then the University of Leningrad (now St Petersburg) and returned to Hungary where he has been employed as Research Scientist and then Head of the Department of Zoology of the Hungarian Academy of Sciences in Budapest until 1990. He then became Research Consultant, a position he has held since. His list of publications includes nine books and about 220 papers in scientific journals. He has described 13 new family-group names, 32 new genera, and about 175 new species. Much of this work has been done since 1990. We expect a steady flow of publications in the future

A systematic study of Peliococcus Borchsenius (Hemiptera: Coccoidea: Pseudococcidae), with descriptions of a new Palaearctic genus and four new species from Turkey

PubMedID: 25781247Within the Phenacoccinae (Hemiptera: Coccoidea: Pseudococcidae), there are four nominal genera that include species with clusters or groups of multilocular disc pores and/or oral collar tubular ducts of more than one size, namely Peliococcus Borchsenius (= Spinococcus Borchsenius and Eupeliococcus S?vescu), Peliococcopsis Borchsenius, Erimococcus Ezzat, and Seyneria Goux. This study analysed molecular data (from the mitochondrial gene cytochrome oxidase I, COI, and a fragment of the D2 and D3 regions of the large subunit ribosomal DNA gene, 28S) from Palaearctic species of Peliococcus, Peliococcopsis and a new genus, Pelionella Kaydan to demonstrate: (i) that Peliococcus and several morphologically similar genera do not form a monophyletic group; (ii) Peliococcus, as currently understood, is not monophyletic, and (iii) the structure of the multilocular disc pores is important for recognising the systematic position of these genera. The morphological data were fitted to the molecular tree to allow reassessment of the generic classification and to produce morphological diagnoses of the genera. Five species have been moved to the genus Erimococcus Ezzat: Peliococcus kimmericus Kiritchenko, P. montanus Bazarov & Babaeva, P. multitubulatus (Danzig), P. salviae Hadzibejli and P. talhouki Matille-Ferrero, as E. kimmericus (Kiritchenko) comb. nov., E. montanus (Bazarov & Babaeva) comb. nov., E. multitubulatus (Danzig) comb. nov., E. salviae (Hadzibejli) comb.nov. and E. talhouki (Matille-Ferrero) comb. nov. In addition, a new species of Erimococcus is described, namely Erimococcus ozani Kaydan sp. nov. Also Peliococcus ilamicus Moghaddam syn. nov. is recognised as a junior synonym of Phenacoccus kimmericus Kiritchenko (previously in Peliococcus, now in Erimococcus). A new genus, Pelionella gen. nov. is introduced to take nine species, namely Peliococcus balteatus Green, P. cycliger Leonardi, P. manifectus Borchsenius, P. stellarocheae Goux, P. glandulifer Borchsenius, P. tritubulatus Kritchenko, P. sablius Goux, P. grassianus Goux, P. proeminens Goux, as Pelionella balteata (Green) comb. nov., Pelionella cycliger (Leonardi) comb. nov., Pelionella manifecta (Borchsenius) comb. nov., Pelionella stellarocheae (Goux) comb. nov., Pelionella glandulifer (Borchsenius) comb. nov., Pelionella tritubulata (Kritchenko) comb. nov., Pelionella sablia (Goux) comb. nov., Pelionella grassiana (Goux) comb. nov. and Pelionella proeminens (Goux) comb. nov. In addition, two species are described as new: Pelionella multipora Kaydan sp. nov. and Pelionella kansui Kaydan sp. nov. Three species, namely Peliococcus daganiae (Bodenheimer), P. orientalis Bazarov and Spinococcus giuliae Pellizzari, are transferred to Phenacoccus as: Phenacoccus daganiae (Bodenheimer), comb. nov., Phenacoccus orientalis (Bazarov), comb. nov. and Phenacoccus giuliae (Pellizzari), comb. nov. Three new species synonymies are recognised: Peliococcus deserticola Ben-Dov & Gerson syn. nov. of Peliococcus cycliger Leonardi (now Pelionella cycliger), Peliococcus albertaccius Goux syn. nov. of Peliococcus manifectus Borchsenius (now Pelionella manifecta) and Peliococcus lycicola Tang syn. nov. is recognised as a junior synonym of Peliococcus chersonensis Kiritshenko. In addition, a new Peliococcus species is described, namely Peliococcus agriensis Kaydan sp. nov. Copyright © 2015 Magnolia Press

Investigations on biological characteristics of Pseudococcus comstocki (Kuwana) (Hemiptera: Pseudococcidae) on different two mulberry species and different temperatures [Pseudococcus comstocki (Kuwana) (Hemiptera: Pseudococcidae)'nin farkli sicaklik koşullarinda ve iki dut türü üzerinde gelişme ve üremesinin incelenmesi]

Asiatic originated Pseudococcus comstocki (Kuwana), the Comstock mealybug (Hemiptera: Pseudococcidae) is polyphagous cosmopolite species. Nowadays it is spreading through to Europe and becoming wide distribution. In this study, the developmental time, survival and fecundity of P. comstocki on two mulberry species (Morus alba and M. nigra) (Moraceae) were studied at four different temperatures (18±1, 23±1, 28±1 and 20-32°C) and thermal constant was calculated. According to results, it appears that performance of P. comstocki and, consequently, its population increase were affected by feeding with different mulberry species and at different temperatures, and M. nigra seems to be more likely susceptible to the mealybug than M. alba in each temperatures because it displayed the highest performance on this host plant. The results showed that the population on M. nigra (rm = 0.123 female/female/day; R0 = 108.933 female/female; T0 = 38.160 day; DT= 5.639 day) developed better than that on M. alba (rm= 0.115 female/female/day; R0 = 84.281 female/female; T0= 38.600 day; DT= 6.032 day) at 28°C. It was found that there was an inverse relationship between the growth period of the population and the temperature, development of the mealybug becoming fully grown was the fastest on both Morus species at 28 °C. The threshold for development (t) and the thermal constant (ThC) of the mealybug on M. nigra was determined as 7.87 °C, K = 513 degree-days respectively; while on M. alba, these parameters were found to be 7.76 °C and K = 518 degree-days respectively

A taxonomic revision of the mealybug genus ferrisia fullaway (Hemiptera: Pseudococcidae), with descriptions of eight new species and a new genus

The mealybug genus Ferrisia Fullaway is revised to include 18 species, based on morphological and molecular data. We distinguish the widespread pest species F. virgata (Cockerell) from morphologically similar species and provide a revised description and illustration for the adult female of F. virgata. We resurrect Dactylopius dasylirii Cockerell stat. rev. from synonymy with Dactylopius virgatus Cockerell as Ferrisia dasylirii (Cockerell) and apply this name to many North American and Caribbean populations previously recognised as F. virgata; F. dasylirii is the most difficult to distinguish morphologically from F. virgata and exhibits morphological and molecular variation among some populations. We designate a lectotype for D. dasylirii Cockerell. Eight new species of Ferrisia are described and illustrated based on the adult female, and named as Ferrisia colombiana sp. n., F. cristinae sp. n., F. ecuadorensis sp. n., F. kondoi sp. n., F. milleri sp. n., F. pitcairnia sp. n., F. uzinuri sp. n. and F. williamsi sp. n. The relationships of five of these new species and five named species are discussed in relation to a previously published phylogenetic tree that was based on nucleotide sequence data. Taxonomically informative morphological features (such as the size, shape and position of discoidal pores associated with the dorsal enlarged tubular ducts and the ventral oral-collar tubular ducts), identified for each of the genetic groups (clades) on the tree, are used to help to diagnose the species. We also describe and illustrate the adult female of a form of F. gilliGullan, found on Magnolia and some other host plants, that has numerous clusters of small ventral oral-collar ducts on the body margins. For seven named species-F. claviseta (Lobdell), F. malvastra (McDaniel), F. meridionalis Williams, F. multiformis Granara de Willink, F. quaintancii (Tinsley), F. setosa (Lobdell) and F. terani Williams & Granara de Willink- we provide revised illustrations of the adult females as well as diagnostic morphological notes and information on distribution and host plants. We also recognise Eurycoccus copallinae Ferris as a junior synonym (syn. n.) of Dactylopius quaintancii Tinsley (now F. quaintancii) and designate a lectotype for E. copallinae. We include photographs of the live appearance of the adult females of six Ferrisia species and also a key to all known species of Ferrisia based on the morphology of the adult females. We transfer the species currently known as Ferrisia floridana (Ferris) to a new monotypic genus, Pseudoferrisia gen. n., as Pseudoferrisia floridana (Ferris) comb. n., and provide a description of the genus and its type species (Ferrisiana floridana Ferris), as well as a new illustration of the adult female.
