Reduced levels of membrane-bound alkaline phosphatase in Vip3Aa-resistant Heliothis virescens
2020
ABSTRACTThe Vip3Aa insecticidal protein fromBacillus thuringiensis(Bt) is produced by specific transgenic corn and cotton varieties for efficient control of target lepidopteran pests. The main threat to this technology is the evolution of resistance in targeted insect pests, thus understanding the mechanistic basis of resistance is crucial to deploy the most appropriate strategies for resistance management. In this work, a laboratory-selected colony ofHeliothis virescens(Vip-Sel) highly resistant to the Vip3Aa protein was used to test whether an alteration of membrane receptors in the insect midgut might explain the resistance phenotype. Binding of125I-labeled Vip3Aa to brush border membran…

Differences in the midgut proteolytic activity of twoHeliothis virescens strains, one susceptible and one resistant toBacillus thuringiensis toxins
1996
The development of resistance to Bacillus thuringiensis toxic proteins is a growing concern because it could threaten both conventional and gene transfer use of this environmentally safe biological insecticide. The most common mechanism of resistance involves changes in binding affinity of toxin receptors in the insect midgut membrane. This has not been the case in Heliothis virescens. We have investigated changes in midgut proteolytic activity as a possibility to explain the resistance observed in this insect species. We have developed an improvement of known methods to demonstrate proteolytic activity in crude extracts. Using this method we have found differences in the proteolytic activi…
First report of the bordered straw, Heliothis peltigera, οn sunflower in Greece
2017
Τον Ιούνιο 2015, καταγράφηκαν προσβολές καλλιeργeιών ηλιάνθου από το έντομο Heliothis peltigera (Lepidoptera: Noctuidae) σe αγροτικές πeριοχές της Πeριφeρeιακής Eνότητας Δράμας. Παρατηρήθηκαν διαβρώσeις στα φύλλα και στους οφθαλμούς από τις προνύμφeς του eντόμου, κυρίως στα προανθικά στάδια ανάπτυξης. Οι προσβολές παρατηρήθηκαν στο 80% των αγρών που eπισκοπήθηκαν, ωστόσο το eπίπeδο προσβολής των φυτών ήταν χαμηλό (<5%) και δeν διαπιστώθηκe πρόκληση οικονομικής ζημίας στις καλλιέργeιeς. Το H. peltigera έχeι αναφeρθeί από τη Νότια και Κeντρική Eυρώπη, τον Καναδά, τη Μέση Ανατολή και την Αφρική να προσβάλλeι διάφορους ξeνιστές. Προσβολές σe καλλιέργeιeς ηλιάνθου έχουν αναφeρθeί από την Ινδία, …
Da Teocle ad Ermocrate: quale identità per i Greci di Sicilia?
2015
Attraverso l'esame delle tradizioni letterarie e dei dati della cultura materiale della Sicilia di età arcaica, si cerca di individuare il contesto storico in cui si sia formata la nozione di Sicelioti, ovvero la consapevolezza di appartenere ad un gruppo etnico omogeneo comprendente tutte le colonie greche dell'Isola, e distinto da altri gruppi greci di madrepatria. A fronte delle recenti teorie basate sul concetto antropologico di ethnicity, che fanno risalire all'epoca della prime fondazioni delle colonie greche di Sicilia la formazione di un'identità etnica siceliota, si tende a mostrare come fino all'epoca della tirannidi arcaiche dell'Isola non vi sia stata la consapevolezza da parte …

Bioactive chromenes from Rhyncholacis penicillata.
1994
Investigation of the aerial parts of Rhyncholacis penicillata afforded the new chromenes, 7-hydroxy-6-(3-methylbutyryl)-5-oxymethyl-chromene (rhynchonin A) and 7-hydroxy-6-(2-methylbutyryl)-6-oxymethylchromene (rhynchonin B). Structures were elucidated by spectroscopic methods and independent synthesis. Rhynchonin A showed broad insecticidal, acaricidal and nematicidal potency including strong biological activity against Heliothis zea.
The "intimate enemies": Edward Dowden, W. B. Yeats and the formation of character
2014
Published version of an article in the journal: Nordic Journal of English Studies. Also available from the publisher at: http://ojs.ub.gu.se/ojs/index.php/njes/article/view/2917 Open Access Stung by Edward Dowden's reluctance to endorse the Irish Literary Revival, W. B. Yeats distanced himself publicly from the TCD Professor. This act of distancing has largely been accepted by subsequent scholarship as a reflection of Dowden's lack of influence on Yeats. Despite obvious disagreements on some key points, this essay will argue that Yeats is close to Dowden on a number of issues, by tracing their intimate dialogue about the writings of George Eliot, Shakespeare and Goethe. The concept of forma…
Humanism and criticism in T. S. Eliot and Carles Riba
2021
T. S. Eliot i Carles Riba són dos autors amb moltes similituds: tots dos van viure aproximadament durant la mateixa època (la primera meitat del segle XX), tots dos van destacar com a poetes i com a crítics, i tots dos van escriure sobre temes literaris semblants, com, per exemple, l’humanisme, i sobre diversos autors de la literatura europea, com Dante, Goethe i Baudelaire. Però les seves diferents circumstàncies biogràfiques i els diferents contextos literaris, socials i polítics van condicionar la seva concepció de l’humanisme i la seva interpretació d’alguns dels principals escriptors de la cultura occidental. L’objectiu d’aquest article és fer un exercici de literatura comparada per …
