Chemosensory Receptors in the Larval Maxilla of Papilio hospiton
2022
Among the butterflies of the genus Papilio (Lepidoptera: Papilionidae), Papilio hospiton (Géné) has a geographical distribution limited to the Mediterranean islands of Sardinia (Italy) and Corsica (France). This is mainly due to the host range that includes only a few plant species of Apiaceae and Rutaceae growing on these islands. In a previous electrophysiological investigation conducted on the maxillary gustatory system of larvae of P. hospiton and its closely phylogenetically related species Papilio machaon, a significantly higher spike activity was shown for the gustatory neurons of lateral and medial styloconic sensilla in P. hospiton when bitter compounds were tested. This effect was…
First report of Antigastra catalaunalis on sesame in Greece.
2017
Τον Αύγουστο του 2016, καταγράφηκαν σοβαρές προσβολές σε καλλιέργειες σουσαμιού από το έντομο Antigastra catalaunalis (Duponchel) (Lepidoptera: Crambidae) σε αγροτικές περιοχές της Περιφερειακής Ενότητας Δράμας. Το A. catalaunalis είναι ένας σημαντικός εχθρός της καλλιέργειας του σουσαμιού σε περιοχές όπου αυτό καλλιεργείται. Παρατηρήθηκαν συμπτώματα προσβολής από τις προνύμφες του εντόμου σε φύλλα, βλαστούς και κάψες. Οι προσβολές καταγράφηκαν σε όλους τους αγρούς με καλλιέργεια σουσαμιού που επιθεωρήθηκαν, με επίπεδα προσβολής υψηλά τα οποία προκάλεσαν οικονομική απώλεια. Στο βαθμό που γνωρίζουμε, αυτή είναι η πρώτη αναφορά σοβαρών προσβολών σουσαμιού από το Α. catalaunalis στην Ελλάδα.
Factores desencadenantes del perjuicio de los simúlidos
2021
El incremento de los daños causados por los dípteros simúlidos, desde finales de la década de los 90, ha suscitado un interés especial en el estudio de este grupo de dípteros en nuestro país. Además de la importancia de los estudios faunísticos, para conocer las especies presentes en nuestros hábitats, resulta de interés conocer otros aspectos ligados a la incidencia de sus ataques tanto al ser humano como a las especies animales de interés veterinario. La revisión del estado actual de la familia Simuliidae en España ha permitido la confección del listado de las 52 especies presentes y sus mapas de distribución. Se han llevado a cabo estudios de eficacia de tratamientos biol…
Les contradictions de l'université de masse dix ans après (1973-1983)
1984
Jean-Pierre Jarousse : Die Widersprüche der Massenuniversität zehn Jahre später (1973-1983). Das von L. Lévy-Garboua vorgestellte Auswahlmodell zur Erklärung der Verschlechterung, die in der französischen Universität im Verlauf der siebziger Jahre empfunden wurde, sowie der scheinbare Widerstand zur Verminderung der Hochschulnachfrage, zeigte, dass die vom Student durchgeführte Kontrolle über seine Studienzeit diesem gestattete, die Universität zu besuchen ohne jedoch hieraus grössere künftige Vorteile zu erwarten. Unter Berücksichtigung der respektiven Entwicklung der Berufssituation der Abiturienten und der Hochschuldiplomierten, behaupten andere Verfasser im Gegenteil, dass der Universit…
Bonding efficacy of an acetone/based etch-and-rinse adhesive after dentin deproteinization
2012
Objectives: to evaluate the effect of sodium hypochlorite (NaOCl) treatment on dentin bonding by means of shear bond strength (SBS) measurements when using Prime&Bond NT (PB NT) adhesive. Ultrastructure of the interfaces was examined by scanning electron microscopy (SEM). Study design: Extracted human third molars were sectioned and ground to expose flat surfaces of superficial or deep dentin. Specimens were randomly assigned to two equal groups, and bonded as follows: (1) according to the manufacturers’ directions, after 35% H3PO4 etching, (2) 5% NaOCl treated for 2 minutes, after 35% H3PO4 etching. Each sample was embedded in a Watanabe shear test assembly for a single plane lap shear. Af…
Differential copper impact on density, diversity and resistance of adapted culturable bacterial populations according to soil organic status
2010
International audience; The effect of copper on the abundance, diversity and resistance of viable heterotrophic and copper resistant bacterial populations (CuR) was evaluated in soils differing only by their amount and type of organic matter. These soils have been obtained using a vineyard soil that had been subjected to three different organic matter managements (Not Amended (NA) or amended with Straw (S) or Conifer Compost (CC)) in a long term field experiment. Soil microcosms were artificially contaminated with copper (250 mg Cu kg−1 of soil) and incubated for 35 days. Throughout the incubation, a differential copper impact on viable heterotrophic and CuR bacterial enumeration was demons…
Rearing of Prays citri on callus derived from lemon stigma and style culture
2000
A new method for rearing the citrus flower moth (Prays citri Mill.) (Lepidoptera, Yponomeutidae) on lemon [Citrus limon (L.) Burm.] callus is reported. In the present research callus (an undifferentiated mass of plant cells that can be grown under sterile conditions on an artificial medium in vitro) was induced from lemon stigma and style explants cultured on Murashige and Skoog (MS) medium supplemented with 500 mg l -1 malt extract, 13.3 μM 6-benzylaminopurine, and 146 mM sucrose. Also somatic embryogenesis and plant regeneration were obtained from the cultures of styles and stigmas of lemon. Adults were obtained from larvae on infested flowers collected in the field. Different oviposition…
LA VIABILITÀ MINORE NELLA SICILIA CENTRO-MERIDIONALE: IL COMPRENSORIO DI CIGNANA TRA LA VIA SELINUNTINA E LA CATINA-AGRIGENTUM
2021
Obiettivo del contributo è esaminare il sistema stradale di età antica, con un’attenzione particolare rivolta alle vie secondarie, in un ben definito comprensorio della Sicilia meridionale, l’area del Progetto Cignana, pochi km ad est di Agrigento. Si tratta di cogliere non tanto i caratteri della viabilità di lunga percorrenza (la via Selinuntina e la via Catina-Agrigentum) quanto piuttosto le interconnessioni tra i principali assi viari, la rete secondaria (spesso attestata lungo i principali corsi d’acqua), gli insediamenti rurali e gli approdi sulla costa. This paper is aimed to analyze the ancient road system in a selected area of the Southern Sicily, between Agrigento and Licata (Cign…
Cloning and characterization of the promoter of Hugl-2, the human homologue of Drosophila lethal giant larvae (lgl) polarity gene.
2007
The human lgl gene, Hugl-2 (llgl2, Lgl2), codes for a cytoskeletal protein involved in regulating cell polarity. Here, we report the identification and functional characterization of the promoter region ( approximately 1.2kb) of the Hugl-2 gene. Luciferase expression assays show a high basal Hugl-2 promoter activity in different cell lines and primary human hepatocytes. Truncations of the promoter identified a GC-rich region important for this activity. Alignment of human and mouse genomic sequences demonstrate that this is an evolutionary conserved region fcontaining putative binding sites for several transcription factors including Elk-1 and Sp-1. Mithramycin A reduces Hugl-2 expression i…
