Extra Nucleolar Activity Associated with Chromosome Segment in The Heredity 56 (1986) 237—241 The Genetical Society of Great Britain Received 22 July 1985 Extra nucleolar activity associated with presence of a supernumerary chromosome segment in the grasshopper Oedipoda fuscocincta J. P. M. Camacho, J. Navas-Castillo Departamento de Genética, Facultad de Ciencias, and J. Cabrero Universidad de Granada, 18071 Granada, Spain. The standard males of Oedipoda fuscocincta show a single active nucleolus organiser region (NOR) located in the secondary constriction of the M9 chromosomes. Nine males from three different populations proved to be heterozygous for a heterochromatic supernumerary segment which is distally located on the S10 chromosome. This also showed NOR activity. All available data seem to support the hypothesis that this extra segment on the S10 chromosome has arisen by translocation of part of the M9 chromosome, specifically that located between the centromere and the secondary constriction.

Meriem*, M. Lotfi, B. Nadhira Laboratoire de recherche Valorisation des actions de l'homme pour la protection de l'environnement et application en santé publique, Université de Tlemcen, BP 119 13000 Tlemcen Algérie *Corresponding author E-mail: [email protected] Received: 28.06.2021. Accepted: 09.07.2021. The Orthoptera represent a crucial link in the food chains as primary consumers. They have long been recognized as crop pests causing extensive damage and thus, arousing scientific interest around their diet. This study aims to know the diet and trophic preferences of two locust species Oedipoda miniata mauritanica (Lucas, 1849) and Oedipoda caerulescens sulfurescens (Saussure, 1884), under natural conditions. The sampling was carried out in 2016 in Ghazaouet, a coastal region of Tlemcen subject to a sub- humid climate. We examined Feces contents by comparing the epidermal fragments of plants ingested by these two locusts with a reference collection prepared from plant species existing in the sampled biotope. This method is practical for field research as it is simple, fast, and objective. The food spectrum of the two Oedipodinae reveals their clear preference for three plant species over all the plants present in the study area, and each species chooses its food according to its availability and nutritional characteristics. Moreover, Oedipoda miniata mauritanica shows a great affinity towards the plant species Lavendula dentata, with a consumption rate > 59%, on the other hand, Oedipoda caerulescens sulfurescens prefers the plant species Lavendula multifida, with a consumption rate >50%.

We studied a population of the Red-winged grasshopper Oedipoda germanica, which is a highly stenotypic and endangered species in Central Europe. The locality studied is completely isolated and at the northern limit of this species distribution (north-west of the Czech Republic). We used capture-mark-recapture in 3 consecutive years (2008–2010). We estimated the total population size using POPAN software to be 136 adults in 2008, 70 in 2009 and 122 in 2010.

    Die Rotflügelige Ödlandschrecke, Oedipoda germanica (Latreille , [1804]) (Caelifera), im Naturpark „Saale-Unstrut-Triasland“ (Sachsen-Anhalt) von Michael WALLASCHEK Zusammenfassung Im Jahr 2005 wurde in einem Projekt zum Pflege- und Entwicklungskonzept des Naturparks „Saale-Unstrut-Triasland e.V.“ (Sachsen-Anhalt) in bekannten und potentiellen Lebensräumen der Rotflügeligen Ödlandschrecke, Oedipoda germanica (LATREILLE, [1804]), das Vorkommen der Art, die genaue Lage und Umgrenzung der Habitate, die Größe der Populationen und deren interne Gliederung, die Struktur der Biotope, die Lage von Ausbreitungsbarrieren oder -korridoren sowie die Gefährdung durch anthropogene und natürliche Faktoren untersucht. Im Naturpark konnten insgesamt vier aktuelle Fundgebiete dieser Kurzfühlerschreckenart mit zusammen sechs räumlich getrennten Populationen nachgewiesen werden: Göttersitz bei Naumburg, eine Population mit ca. 30 Tieren; Rödel bei Großwilsdorf, 2 Populationen mit ca. 15 und ca. 5 Tieren; Schafberg bei Zscheiplitz, zwei Populationen mit ca. 30 und ca. 150 Tieren; Steinbruch am Lohholz bei Weischütz, eine Population mit ca. 10 Tieren). Bei letzterem Fundort handelt es sich um den Erstnachweis, zugleich um den derzeit nördlichsten bekannten in Sachsen-Anhalt und im Areal. Im Altfimdort „Himmelreich“ bei Bad Kosen gelang dagegen die Bestätigung des Fundes von 1935 nicht. Ein Vergleich mit den Verhältnissen in anderen Teilen des Areals ergab, daß die Populationsgröße nur in einer Untersuchungsfläche auf dem Schafberg - zumindest theoretisch -
