Key words: Heteroptera, Nabidae, new record, Argentina. 1 Entomology Department, North Dakota State University, Dept. 7650, P.O. Box 6050; Fargo, ND. USA. 2 Departamento de Zoologia Medica, Centro de Estudios en Biodiversidad (CEBCh), Magallanes No 1979, Osorno, Chile.* Autor por correspondencia: eduardo.faundez@ndsu.eduFecha de Recepcion: 30 Enero, 2015.Fecha de Aceptacion: 10 Junio, 2015. Nabidae es una familia de insectos heteropteros que cuenta con cerca de 500 especies distribuidas en 20 generos (Schuh & Slater 1995). Los nabidos son insectos predadores, caracterizados por sus patas protoracicas adaptadas para cazar y manejar presas (Schuh & Slater 1995). Por esta razon es que las especies de esta familia son ampliamente usadas como controladores de plagas (Braman 2000); adicionalmente tambien son de interes por su capacidad de picar a seres humanos de forma adventicia (Faundez & Carvajal 2011). En Argentina esta familia ha sido revisada recientemente y se encuentra representada por 14 especies clasificadas en cinco generos (Cornelis & Coscaron 2013); sin embargo, para algunas especies aun existen pocos registros, especialmente en las zonas aridas del noroeste del pais.

first ever report of a bite by nabis argentinus meyer dur hemiptera heteroptera Nabidae on a human
Biodiversity and Natural History, 2017Co-Authors: Marcela Cornelis, Fernando Diez, Maria Del Carmen CoscaronAbstract:Herein, we described the first ever reported bite of Nabis argentinus Meyer-Dur 1870 on a human. The bite was registered in the locality Santa Rosa La Pampa, Argentina (36°37'29.02"S, 64°17'19.13"W). The insect was not provoked by the victim, and thus, the bite was probably not in self-defense. We therefore concluded that the insect bite the victim because it was searching for sources of hydration.

zur kenntnis der raubwanze himacerus apterus f heteroptera Nabidae teil i1
Journal of Applied Entomology, 2009Co-Authors: H KoschelAbstract:Studies on the entomophagous bug Himacerus apterus F. (Heteroptera, Nabidae). Part I deals with: systematic and distribution, - rearing methods, - morphology of adults, eggs and larvae, - function of proposcis and development of H. apterus. The species occurs in Europe and in the Middle and South of Asia. Pbormia regina-(Dipt.) larvae are the optimal food for the bug with view to mass rearing. 89% brachypterous and 11% macropterous ♀ ♀ as well as 98% brachypterous and 2 macropterous ♂ ♂ have been found in Bavaria in 1967 and 1968. Descriptions are given of internal genitalia, eggs, larval stages and adults with special consideration of construction and function of the proboscis. There were 4 larval stages. The duration of their development amounted to 7.7 - 7.9 - 10.2 and 15.2 days.

zur kenntnis der raubwanze himacerus apterus f hetereptesa Nabidae
Journal of Applied Entomology, 2009Co-Authors: H KoschelAbstract:Abstract Studies on the entomophageous bug Himacerus apterus F. (Heteroptera, Nabidae). Part 2 deals with the biology, ethology and ecology of H. apterus. The average number of eggs amounted to 20,2 per female. The eggs are deposited within the stems of lower plants where they hibernate. H. apterus is very polyphagous. The young larvae feed on little insects and mites living on gramineae and herb plants. The third instars climb bushes and trees. The intraspecific behaviour depends on the degree of satiaton. The bugs show a menotactic orientation: by help of rays they are able to keep fixed directions. Vertical patterns are of particular importance For orientation. By means of an actograph, constructed for this purpose, the running-activity was settled. H. apterus avoids agricultural localities. Chief biotops of this species are bright pine woods grown with gramineae and bushes. The employment of H. apterus for biological control of forest pests is not yet possible by reason of cannibalism and deficncy of eggs. Zusammenfassung Zur Erweiterung der bisher geringen Kenntnisse uber die in bayerischen Kiefernwaldern stellenweise recht haufige Raubwanze Himacerus apterus F. wurden 1967–69 systematische, geographische, morphologische, biologische, ethologische und okologische Untersuchungen durchgefuhrt. Die systematische Stellung sowie die Verbreitung der Art werden dargestellt. H. apterus kommt auser in den Alpen und auf den Nordfriesischen Inseln im gesamten Gebiet der Bundesrepublik vor. Die fur eine Aufzucht der Wanze gunstigsten Methoden und Bedingungen werden beschrieben. Die leicht beschaffbaren Maden der Glanzfliege Phormia regina erwiesen sich als optimale Ernahrungsbasis fur eine Massenzucht von H. apterus. Der ausere Korperbau sowie die auseren und inneren Geschlechtsorgane beider Geschlechter werden beschrieben. In den bayerischen Untersuchungsgebieten waren 1967 und 1968 von 385 H. apterus-lmzgmes 89% kurzfluglige und 11% langfluglige Weibchen sowie 98% kurzfluglige und 2% langfluglige Mannchen. Das Ei und die 4 Larvenstadien der Raubwanze werden beschrieben. Zu den Funktionen des Russels zahlt wahrscheinlich auch die mechanische Aufbereitung der gelosten Nahrungspartikel. Der von H. apterus in die Beute gespritzte Stoff ist ein Nervengift. Das Gesamtgewicht der von einem H. apterus-Welbchen in 66 Minuten durch Gift getoteten Beutetiere betrug etwa 500 mg. Die Nahrungsaufnahme vollzieht sich im Wechselspiel zwischen Speichel-Ausscheidung und -Aufnahme. Die Befruchtung der Eier findet bereits in den Eischlauchen statt. Das H. apterus-Weibchen besitzt im Gegensatz zu den meisten anderen Wanzen keinen Spermienbehalter (Receptaculum seminis). Die Eizahl betrug im Mittel 20,2 (ausgebildete Eier). Vom Korpergewicht des Weibchens last sich auf Grund des unterschiedlichen Ernahrungszustandes nicht auf die Anzahl ausgebildeter Eier schliesen. Die Eier werden im Herbst in die Stengel von Krautern und Grasern hinein abgelegt, wo sie uberwintern. Die Entwicklung der Larvenstadien dauerte bei 21–22°C im Mittel 7,7 - 7,9 - 10,5 und 15,2 Tage. Es gelang, aus abgetoteten Weibchen herauspraparierte Eier zu uberwintern und zur Entwicklung zu bringen. Das Nahrungsspektrum von H. apterus ist sehr umfangreich. Die Erst- und Zweitlarven ernahren sich von kleinen Insekten und Milben der Krautschicht. Von der Drittlarve ab geht H. apterus auf Strauchern und in Baumkronen dem Beutefang nach. Die Totungsrate richtet sich nach der Beutedichte. Sie betrug bei Beutetieruberangebot maximal fast 1 Beutetier pro Tag. Unter Laborverhaltnissen ist H. apterus schwacheren Artgenossen gegenuber kannibalistisch. Das Verhalten der Artgenossen untereinander wird vom Sattigungsgrad bestimmt. Zwischen den Geschlechtern gibt es deutliche Verhaltensunterschiede. H. apterus orientiert sich im Raum menotaktisch: Mit Hilfe von Lichtstrahlen werden bestimmte Richtungen eingehalten (Lichtkompas-Orientierung). Besondere Bedeutung fur die Orientierung haben auch vertikale Reizmuster. Charakteristisch fur H. apterus sind Putzbewegungen mehrerer Beine zugleich. Optische und taktile Reize spielen die Hauptrolle beim Beutefang. Die Laufaktivitat der Wanze wurde mittels eines hierfur konstruierten Aktographen registriert. Hinsichtlich der Biotop-Bindung ist H. apterus nicht euryok. Sie meidet landwirtschaftliche Kulturflachen. Hauptbiotop ist der lichte, nicht zu trockene Kiefernwald mit ausgebildeter Kraut- und Strauchschicht. Die wichtigsten biotischen Umweltfaktoren sind die Vogel als rauberische Feinde. Unter den abiotischen Faktoren dominiert die Kombination von Temperatur- und Luftfeuchtigkeit. Die Imagines sind kalteempfindlicher als die Larven. Ein Einsatz von H. apterus als Mittel der biologischen Schadlingsbekampfung scheitert - zumindest vorerst - am Kannibalismus der gefangengehaltenen Tiere sowie am Mangel an Eiablagen.

achiasmatic male meiosis in the heteropteran genus nabis Nabidae hemiptera
Hereditas, 2008Co-Authors: Seppo Nokkala, Christina NokkalaAbstract:Male meiosis in three species of Nabis (N. brevis, N. flavomarginatus, N. limbatus) was studied. All species have the chromosome number 2n=18 (16A+XY). Nucleolar organizing regions were found to be located on the sex chromosomes. Male meiosis is characterized by the presence of a prominent diffuse stage. Autosomal bivalents during late meiotic prophase and metaphase I consist of two parallelly aligned chromosomes; no traces of chiasmata could be found. The cytology of Nabis is further characterized by the lack of telokinetic activity of chromosomes in male meiosis, the presence of interkinesis stage, the nonradiality of the first metaphase plate and the radiality of the second metaphase plate, and the distance pairing of the sex chromosomes instead of the usual touch-and-go pairing at second metaphase. The significance of cytological characteristics in constructing the phylogeny of the Heteroptera is discussed.

Direction of karyotype evolution in the bug family Nabidae (Heteroptera): New evidence from 18S rDNA analysis
European Journal of Endocrinology, 2007Co-Authors: Christina Nokkala, Valentina G Kuznetsova, Snejana Grozeva, Seppo NokkalaAbstract:The bug family Nabidae (Heteroptera) includes taxa showing either a low chromosome number 2n = 16 + XY or high chromosome numbers 2n = 26 or 32 + XY. In order to reveal the direction of karyotype evolution in the family, a molecular phy- logeny of the family was created to reveal the taxon closest to the ancestral type and hence the ancestral karyotype. The phylogeny was based on a partial sequence of the 18S rDNA gene of both high and low chromosome number species belonging to the subfami- lies Prostemmatinae and Nabinae. Phylogeny created by the Neighbour Joining method separated the subfamilies, Prostemmatinae and Nabinae, which form sister groups at the base of this phylogenetic tree, as well as within the Nabinae, tribes Nabini and Arach- nocorini. Combining karyosystematic data with the phylogeny of the family indicated that the ancestral karyotype was a high chro- mosome number, consisting of 2n = 32 + XY. During the course of evolution changes have occurred both in meiotic behaviour of the sex chromosomes and in the number of autosomes. The direction of karyotype evolution was from a high to low autosome number. Abrupt decreases in the number of autosomes have occurred twice; firstly when the tribe Arachnocorini differentiated from the main stem in the subfamily Nabinae and secondly within the tribe Nabini, when within the genus Nabis 2n = 16 + XY species diverged from the 2n = 32 + XY species. A scheme of the sequence of events in karyotype evolution during the evolution of the Nabidae is presented.

cytogenetic characterization of the trinidad endemic arachnocoris trinitatus bergroth the first data for the tribe arachnocorini heteroptera cimicomorpha Nabidae
Folia Biologica, 2007Co-Authors: Valentina G Kuznetsova, Jo-anne Nina Sewlal, Snejana Grozeva, Seppo NokkalaAbstract:As an extension of the ongoing cytogenetic studies of the bug family Nabidae (Heteroptera: Cimicomorpha), the first evidence for the tribe Arachnocorini (the subfamily Nabinae), with reference to the Trinidad endemic, Arachnocoris trinitatus Bergroth, is provided. This is an attempt to gain a better insight into the evolution, systematics and within-family relationships of the family Nabidae. The studies were conducted using a number of cytogenetic techniques. The male karyotype (chromosome number and size; sex chromosome system; NOR location; C-heterochromatin amount, distribution and characterization in terms of the presence of AT-rich and GC-rich DNA), and male meiosis with particular emphasis on the behavior of the sex chromosomes in metaphase II are described. Also investigated are the male and female internal reproductive organs with special reference to the number of follicles in a testis and the number of ovarioles in an ovary. A. trinitatus was found to display a number of characters differentiating it from all hitherto studied nabid species placed in the tribe Nabini of the subfamily Nabinae, and in the tribe Prostemmatini of the subfamily Prostemmatinae. Among these characters are chromosome number 2n = 12 (10 + XY), the lowest within the family, nucleolus organizer regions (NORs) situated on the autosomes rather than on the sex chromosomes as is the case in other nabid species, and testes composed of 3 follicles but not of 7 as in other nabids. All the data obtained suggest many transformations during the evolution of A. trinitatus.

new cytogenetic data on Nabidae heteroptera cimicomorpha with a discussion of karyotype variation and meiotic patterns and their taxonomic significance
European Journal of Entomology, 2004Co-Authors: Valentina G Kuznetsova, Snejana Grozeva, Seppo NokkalaAbstract:As a part of ongoing cytogenetic studies on the bug family Nabidae (Heteroptera), the karyotypes and meiotic patterns of male Nabis (Aspilaspis) viridulus Spinola, 1837, N. (A.) indicus (Stal, 1873) (subfamily Nabinae) and Prostemma guttula (Fabricius, 1787) (subfamily Prostemmatinae) are described. N. viridulus and N. indicus differ from P. guttula in their chromosome numbers, which are 2n = 32 + XY and 2n = 26 + XY, respectively, and behaviour of the sex chromosomes in male meiosis, which, respectively, show "distance pairing" and "touch- and-go pairing" in spermatocyte metaphase II. The karyotype of 2n = 34 and "touch-and-go pairing" are considered to be plesiomor- phic characters in Nabidae. The evolutionary mechanisms that might underlie different chromosome numbers, the taxonomic significance of karyotype variation and the distribution of meiotic patterns in the family, are discussed.
