Macrolepidopterele din sudul Dobrogei Die Makrolepidoptera der Süddobrudscha (Südostrumäniens) László Rákosy1, Levente Székely2 1Institutul de Cercetări Biologice, Republicii 48, Cluj-Napoca, Romania .2Str. Fîneţii nr. 15, Săcele, Braşov, Romania article no.: Entomologica romanica 1: 17-62, 1996 Zusammenfassung: Vorliegende Arbeit umfaßt sämtliche bekannte Daten über die sogenannten “Makrolepidopteren" (einschließlich Cossidae, Hepialidae, Sesiidae und Zygaenidae) aus dem südlichen Teil der Dobrudscha (Südostrumänien). Ausgehend von eigenen und Literaturdaten weisen die Autoren 792 Arten und Unterarten von Makrolepidopteren, nach. Die wissenschaftliche Bedeutung der Ökosysteme der südlichren Dobrudscha liegt auch in der Anzahl von über 45 Taxa von Makrolepidopteren, die aus diesem Gebiet erstmalig für die Fauna Rumäniens erwähnt Wurden. Über 40 Arten sind aus anderen Teilen Rumäniens nicht bekannt (z.B.: Dyspessa salicicola, Malacosoma castrensis shardaghi, Nychiodes waltheri, Asovia maeoticaria, Dyscia sicanaria osmanica, Pyrgus armoricanus, Zerynthia cerysi ferdinandi, Pseudophilotes bavius egea, Z. osterodensis, Z. loti caliacrensis, Z.  purpuralis pluto, Cryphia tephrocharis, Luperina dumerilii, Euxoa glabella, Dichagyris melanura albida, Agrotis obesa nivea, Yigoga flavina, Episema lederi, E. korsakovi pennatula u.a.). Die zoogeographische Analyse der Familie der Noctuidae berechtigt die Autoren zu der Behauptung, daß sich im Süden der Dobrudscha die größte Anzahl pontische und pontomediterrane Elemente der Fauna Rumäniens konzentriert. Die Wälder und die reliktäre Steppe der südlichen Dobrudscha bewahren Pflanzen- und Tiergemeinschaften, die in anderen Teilen Europas nicht vorkommen. Leider erlitten gerade diese interessanten Gebiete und Ökosysteme in den letzten Jahren Zerstörungen, die sich in der Reduzierung der Anzahl der Arten bei Pflanzen und Tieren äußern. Neben Faktoren die diese Umweltschäden bewirken, werden von den Autoren konkrete Maßnahmen zum Schutz, und Erhalt der Ökosysteme vorgeschlagen. Die Arbeit schließt mit der vollständigen faunistischen Artenliste mit Hinweisen betreffend die Häufigkeit und mit der Aufzählung der genauen Fundorte	[details, abstract]	[pdf]

(C.) petriceki, Dicerca (Argante) moesta, Palmar festiva, Anthaxia (s.str.) midas and Chrysobothris leonhardi. The species Anthaxia kiessenwetteri, Anthaxia rossica, Anthaxia anatolica and Anthaxia nigrojubata incognita are known in Romania only from a few recordings from papers published abroad. Within this paper there are figures and identification keys of the species mentioned above as well as of those they resemble mostly from the Romanian fauna. The suitable labels of the specimens, the host plants and the zoogeographical origins and distribution are also given.	[details, abstract]	[pdf]
Imbalances between the sexes in Mantis religiosa populations Dezechilibrul dintre sexe în populaţiile de Mantis religiosa Ildikó Hideg1 1Lorand Eotvos University, P.O. Box 514, H-1055, Budapest, Hungary article no.: Entomologica romanica 1: 77-82, 1996 Rezumat: Însumând rezultatele cercetărilor conduse timp de 17 ani într-o arie experimentală din Budapesta, am fost surprinsă de raportul inegal dintre sexe la Mantis religiosa. Cauza principală este dată de partenogeneza specifică acestei specii, iar cauza secundară, de mortalitatea crescută a descendenţei mascule.	[details, abstract]	[pdf]
Studii ecologice la specii de lepidoptere nocturne în zona Cluj (Transilvania, România), prin cercetări cu capcane feromonale şi capcane luminoase. 1. Caracterizarea zonei, metoda de lucru, lista sistematică şi consideraţii asupra abundenţei speciilor de Noctuidea capturate la capcana luminoasă (1986-1990) Ecological studies on nocturnal Lepidoptera species in Cluj area (Transylvania, Romania) by means of pheromonal and light traps. 1. The caracterisation of the region, methods, the systematique list and considerations about abundance of Noctuidea species catched in light traps during 1986-1990 Gheorghe Stan1, Ioan Coroiu2 & László Rákosy1 1Institutul de Cercetări Biologice, Republicii 48, Cluj-Napoca, Romania 2Babeş-Bolyai University, Catedra de Zoologie, Clinicilor 5-7, 40006 Cluj-Napoca, Cluj County, Romania article no.: Entomologica romanica 1: 83-137, 1996 Summary: Ecological studies in Lepidoptera species with nocturnal behavior, on the basis of sampling data with light and pheromone traps (and other methods), are part of biological, ecological and behavioural researches for monitoring insect species and control in pest Lepidoptera. These studies were initiated in Cluj area (Romania) in 1980 at Institute of Biological Research, Laboratory of Experimental Entomology. In the paper are presented the species list, catched in light trap during 1986-1990, the type of light trap, the period of flight and variation in abundance for Noctuoidea populations. The catched fauna were analysed in correlation with vegetation, and possible relationships between species and the preferential host plants were presented for characteristic habitats of the area (grasslands and hay fields, wet meadows, river meadows forests, deciduous forests, shrubs, vegetable culture and another agroecosystems). On the other hand, the concept of pest species in the area was discussed. During 1986-1990 were catched 42250 individuals for 320 species and the Noctuidae family was prevalent. The population variability and variation in abundance were analysed by means of the quotient of generation (CG), the index of overwintering (IH) (after Meszaros et al. 1979), the coefficient of variation (Cv) (after Spitzer & Rejmanek 1980; Rejmanek & Spitzer 1982), the annual ratio (RA) for monovoltine species, and the regression equation (y=a+bX; where y is the mean annual catch ant the X is the year). For bivoltine and monovoltine species (with mean > 10 individuals/year, and mean< 10 individuals/year), the realtion between the coefficient of variation and mean was analysed by means of the regression equation (where y is Cv and X is the mean). A good cluster and a positive correlation was obtained for bivoltine species with the mean between 10-60 individuals and Cv=0.28-1.43. For majority of species, sex ratio (RS), the sexual index (IS) and the emergence model (the phonologic type) were established. These parameters were utilised with their initial meaning after cited authors, and they were a good modality in ecological studies for lepidoptera populations. For catch, two types of traps were used (Fig. 2, Fig. 3) and they were installed in characteristic habitats (Fig. 10). The influence of light trap model, the site and quality of the light source on the level of catches (Table 5) was analysed. The importance of the light trap for ecological studies in insects as sampling method, single or in combination with another techniques is discussed.	[details, abstract]	[pdf]

Evaluarea numărului de spermatofori şi ouă în studiul capacităţii reproductive la femelele unor specii de lepidoptere capturate în capcana luminoasă Ecological studies on nocturnal Lepidoptera species in Cluj area (Transylvania, Romania) by means of pheromonal and light traps. 2. Evaluation of the number of spermatophores and eggs for the study of reproductive capacity in female Lepidoptera species catched in light trap Gheorghe Stan1, Viorica Chis2, Ioan Coroiu2 & László Rákosy1 1Institutul de Cercetări Biologice, Republicii 48, Cluj-Napoca, Romania 2Babeş-Bolyai University, Catedra de Zoologie, Clinicilor 5-7, 40006 Cluj-Napoca, Cluj County, Romania article no.: Entomologica romanica 1: 139-158, 1996 Summary: Reproductive status of females in 86 Lepidoptera species (with 8620 individuals) collected in light trap, was anlysed by spermatophores and eggs counts. Only females with maximum 10 individuals per species were considered. The number of spermatophores was determined by dissecting the bursa copulatrix and the amount of mass eggs were noted and counted in ovarioles and oviductus communis. The stages of eggs evolution were classified as immature eggs (no chorionated oocytes), and mature eggs (chorionated oocytes).	[details, abstract]	[pdf]
