Extremely potent antifeedant neo-clerodane derivatives of scutecyprol A
2004
Two known neo-clerodane diterpenoids, scutecyprol A (1) and scutalbin C (2), have been isolated from the acetone extract of the aerial parts of Scutellaria sieberi. The antifeedant activity of scutecyprol A (1), of its 15-oxo derivative (3), and of several halohydrins (4-9), synthesized starting from compounds 1 and 3, against Spodoptera littoralis have been determined and structure-antifeedant relationships are discussed.
Intra- and Trans-Generational Phenotypic Responses of the Greater Wax Moth, Galleria mellonella, to a Low-Nutrition Larval Diet
2020
We investigated the intra- and trans-generational effects of larval diet on immune function, body size and development time of the greater wax moth, Galleria mellonella (Lepidoptera: Pyralidae). We found that moths reared on a diet diluted with cellulose (a low-nutrition diet) were about one-third smaller, had about one-fifth longer development time and exhibited about 10% stronger encapsulation responses as compared with moths reared on the standard diet. The low-nutrition parental diet prolonged the development time of male offspring that were fed the low-nutrition diet by about 4% and the development time of female offspring that were fed the standard diet by about 1%. However, females t…
Macrolepidoptera (Insecta: Lepidoptera) Indicator of Climate Changes
2011
Lately, it has become increasingly clear that global warming has a significant impact on a broad range of organisms, regardless of their ecological and geographical spread. Temperature is one of the most important abiotic factors that determine the spatiotemporal dynamics of structural and functional parameters of populations of Lepidoptera and influencing production and survival of these species of insects in nature. Climate warming has the potential to affect some processes related to the ecology and life cycle of the butterfly, especially directly controlled temperature, such as: gathering the required temperature for a species to reach reproductive maturity, growth initiation and cessat…
High Bacterial Agglutination Activity in a Single-CRD C-Type Lectin from <em>Spodoptera exigua</em> (Lepidoptera: Noctuidae)
2017
Lectins are carbohydrate-interacting proteins that play a pivotal role in multiple physiological and developmental aspects of all organisms. They can specifically interact with different bacterial and viral pathogens through carbohydrate-recognition domains (CRD). In addition, lectins are also of biotechnological interest because of their potential use as biosensors for capturing and identifying bacterial species. In this work, three C-type lectins from the Lepidoptera Spodoptera exigua were produced as recombinant proteins and their bacterial agglutination properties were characterized. The lowest protein concentration producing bacterial agglutination against a panel of different Gram+ an…
UNA LISTA COMENTADA DE LOS SPHINGIDAE DE BOLIVIA (INSECTA: LEPIDOPTERA)
2001
An annotated checklist of the Sphingidae (hawkmoths) of Bolivia is presented. A total of 189 species and subspecies are confirmed. Locality data derived from specimens in the collections of the Department of Entomology of the Natural History Museum Noel Kempff Mercado of Santa Cruz de la Sierra; the Bolivian Collection of Fauna, La Paz; The Natural History Museum, London; and the Carnegie Museum of Natural History, Pittsburgh, are given. A map of these localities and a synoptic discussion of their geography and ecology are also provided. Data on species not represented in these collections are collated from the publications of J. Haxaire and D. Herbin and presented. Diagnostic features to e…
Synthesis of (Z)-5-Decenol and (Z)-5-Decenyl Acetate, Components of the Sex Pheromones of a Variety of Lepidoptera.
2003
Two simple Wittig procedures for the synthesis of (Z)-5-decenol and (Z)-5-decenyl acetate based on the monoacetylation or monobromination of 1,5-pentanediol were followed.

The Protected Species of Lepidoptera in the Oak Forest "Dumbrava Sibiului", Romania
2011
This paper presents the results of research on Lepidoptera fauna of protected forest located Dumbrava Sibiu, near Sibiu city . The theme of the work is included in a study of forest biodiversity and Sibiu Lepidoptera "Dumbrava Sibiului" is part of a school project postdoctoral lasted several months in the forest.
 The first data on Lepidoptera fauna of the forest were reported by Daniel Czekelius collection and analysis covers a total of 45 species collected from the surrounding forest. An important contribution collections were then collected in the Transylvanian Saxons in 1009 and until around 1960 years and have made such an important contribution to knowledge of this group of insec…
An Overview of Genus-Level Taxonomic Problems Surrounding <I>Argyroploce</I> Hübner (Lepidoptera: Tortricidae), with Description of a New…
2002
Argyroploce unedana Baixeras, new species, is described from the Iberian Peninsula. The species is closely related to A. arbutella (L., 1758), which occurs on most of the European continent; the two species are allopatric. Although they share similar biologies, the two can be distinguished by structures of the male and female genitalia. Genitalia variability is analyzed. Forewing patterns and hindwing anal roll are discussed in relation to their systematic significance. The olethreutine wing pattern is reexamined. A review of the genus-level taxonomic problems surrounding Argyroploce Hubner, [1825] and allied genera suggests a fragile situation in the present systematic scenario within the …
Parasitization ofEphestia kuehniellaZeller (Lep., Pyralidae) byPhanerotoma (Phanerotoma) ocularisKohl (Hym., Braconidae)
1993
Laboratory studies of the parasitism by P. (P.) ocularis into E. kuehniella showed that this parasitoid had a great capacity to parasitize the host. Real parasitism rate turned between 84.5% and 100% whereas effective parasitism and adult emergence rate were, comparatively, lower. Superparasitism rate was low (16.57 %).

Parasitismus, Superparasitismus und Schlupfraten Laboruntersuchungen zur Parasitierung von Ephestia kuehniella durch P.
