Nota sobre tortrícidos ibéricos del género Pammene Hübner, [1825] (Lepidoptera : Tortricidae)

2006

Se dan a conocer dos especies de Tortricidae (Olethreutinae, Grapholitini) del género Pammene Hübner, [1825]: P. obscurana (Stephens, 1834) y P. suspectana ([Lienig] & Zeller, 1846). Éstas se diagnosticaron mediante el estudio de la genitalia de ejemplares masculinos capturados en Cataluña en trampas delta de base pegajosa, cebadas con feromona sexual de Cydia pomonella (Linnaeus, 1758) y de Grapholita molesta (Busck, 1916). La primera es nueva para Cataluña (España); la segunda lo es para la fauna íbero-balear. Two species of Tortricidae (Olethreutinae, Grapholitini) belonging to the genus Pammene Hübner, [1825]: P. obscurana (Stephens, 1834) and P. suspectana ([Lienig] & Zeller, 1846) are…

Contribución al estudio de la familia Tortricidae Latreille, 1803 (Lepidoptera), con especial referencia a la fauna neotropical

2015

La familia Tortricidae Latreille es uno de los grupos de lepidópteros más diversos con alrededor de 10.000 especies, distribuidas en tres subfamilias (Chlidanotinae, Tortricinae y Olethreutinae), 20 tribus y más de 1070 géneros. Dentro de esta familia se encuentran plagas de gran importancia económica como el gusano de las yemas del abeto, Choristoneura fumiferana Clemens 1865 (Tortricinae: Archipini), y el gusano de la manzana, Cydia pomonella L. 1758 (Olethreutinae: Grapholitini). La clasificación de esta familia está basada en caracteres morfológicos, principalmente en los genitalia de los machos y la venación alar. Recientemente la filogenia del grupo ha recibido especial atención desde…

A catalogue of the Castniidae (Lepidoptera) in the California Academy of Sciences, with general and historical comments

2019

A catalogue of the Castniidae (Lepidoptera) in the California Academy of Sciences, with general and historical comments. The material representing 168 specimens with 46 species and subspecies belonging to the Castniidae (Lepidoptera) deposited in the California Academy of Sciences was studied. A brief comment on the history of Academy is provided, as well as general comments on natural history, distribution and other details for each mentioned species and subspecies.

Analysing the origins of the strong variability of impact by Tischeria ekebladella, a common mining moth on oak leaves.

2015

Tischeria ekebladella (Lepidoptera : Gracillariidae) is a common moth with its caterpillar often mining oak leaves, morerarely chestnut leaves. As a rule, the mining impact of the species exhibits strong variations according to locations,inviting to investigate quantitatively the respective contributions of the three main factors that regulate the level of minesdensity within host. As the direct monitoring in the fi eld of these governing factors is very diffi cult (when not virtuallyimpossible), we use a newly designed procedure (“MELBA”) which allows tracing back to these factors indirectly, on thebasis of posterior, easily recorded data (in terms of the histogram of the distribution of t…

Immunological priming in the wood tiger moth (Parasemia plantaginis)

2014

Hyönteisiin lukeutuu monia merkittäviä tuholaisia, taudinvälittäjiä ja hyödyllisiä lajeja, minkä takia hyönteisten taudit, taudinaiheuttajat ja immuunipuolustus ovat ekologisesta, ekonomisesta ja lääketieteellisestä näkökulmasta tärkeitä tutkimuskohteita. Viimeaikaiset tutkimukset paljastavat hyönteisten ja muiden selkärangattomien immuunijärjestelmien pystyvän erikoistumaan ja luomaan pitkäkestoista immuniteettia. Jälkimmäinen ilmiö tunnetaan tieteellisissä artikkeleissa nimellä ”immunological priming”, jonka voisi kääntää suomeksi esimerkiksi ”immuunipohjustukseksi”. Immuunipohjustus on muistinkaltaista vastustuskykyä, joka auttaa elimistöä puolustautumaan tehokkaammin toistuvia tartuntoj…

One Species, Hundreds of Subspecies? New Insight into the Intraspecific Classification of the Old World Swallowtail (Papilio machaon Linnaeus , 1758)…

2022

The Old World swallowtail Papilio machaon Linnaeus, 1758 is one of the most well-known and most characteristic members of the family Papilionidae. Over the past two centuries, the butterfly has been the subject of many studies. P. machaon is characterised by a tendency to change the wing colour pattern. In turn, due to the great interest of collectors and amateur entomologists, these studies have been converted into the description of over 100 colour forms, aberrations and subspecies. In this study, mitochondrial DNA (mtDNA), 16S rDNA and cytochrome b sequences were used to examine the correlation between the intraspecific classification and genetic structure of P. machaon. The study used 8…

Study of the bacillus thuringiensis Cry1Ia protein oligomerization promoted by midgut brush border membrane vesicles of lepidopteran and coleopteran …

2020

Bacillus thuringiensis (Bt) produces insecticidal proteins that are either secreted during the vegetative growth phase or accumulated in the crystal inclusions (Cry proteins) in the stationary phase. Cry1I proteins share the three domain (3D) structure typical of crystal proteins but are secreted to the media early in the stationary growth phase. In the generally accepted mode of action of 3D Cry proteins (sequential binding model), the formation of an oligomer (tetramer) has been described as a major step, necessary for pore formation and subsequent toxicity. To know if this could be extended to Cry1I proteins, the formation of Cry1Ia oligomers was studied by Western blot, after the incuba…
