Observations on midgut of Apis mellifera workers (Hymenoptera: Apoidea) under controlled acute exposures to a Bacillus thuringiensis-based biopestici…
2016
International audience; AbstractMorphostructural investigations have been carried out on Apis mellifera workers treated with single controlled acute exposures to a biopesticide containing Bacillus thuringiensis (Bt), to detect midgut changes until 96 h. Our findings show concentration-dependence of these changes, reflecting in different degrees on both mortality and behaviour. In particular, some midgut changes are also found 96 h after treatment. Our results show that the tested product does not affect survival at presumable environmental concentrations, so confirming the lesser toxicity of Bt-based biopesticides compared to other pesticides. However, in the light of the discovered long-te…
A morphological and mitochondrial assessment of Apis mellifera from Palermo, Italy
1998
A characterization of the honey bees from western Sicily (Palermo, Italy) is presented. Mor- phological comparisons to A. m. ligustica were made using data taken from honey bee populations from southeastern (Bari) and central (Emilia Romagna) Italy. The honey bees of the Palermo area have distinct morphological differences compared to the mainland honey bees. The mtDNA haplotype common in subspecies within the African lineage of A. mellifera predominated in the Sicilian honey bee samples (13 out of 16). These results suggest both the potential and the desirability to expend efforts to conserve A. m. sicula. © Inra/DIB/AGIB/Elsevier, Paris
Apoyo a la autonomía, satisfacción de las necesidades psicológicas y bienestar : invarianza de un modelo estructural en futbolistas y bailarines
2015
La teoría de las necesidades psicológicas básicas (Deci y Ryan, 2000) defiende que en los contextos sociales en los que se apoya la autonomía se promueve el bienestar a través de la satisfacción de las necesidades psicológicas básicas. En base a este marco teórico, el objetivo del presente trabajo fue triple: primero, poner a prueba un modelo en el que se analizaba la secuencia: percepción del apoyo a la autonomía ofrecido por el profesor/entrenador - satisfacción de las necesidades psicológicas básicas - bienestar; segundo, examinar el papel mediador de las necesidades, y tercero, estudiar la invarianza del modelo entre dos poblaciones. Participaron 197 bailarines (Medad = 18,65 ± 3,73) y …
The role of native flower visitors in pollinating Opuntia ficus-indica (L.) Mill., naturalized in Sicily
2011
Abstract The role of insects in pollination and consequently in fruit set and quality was assessed in two commercial orchards of the cactus pear, Opuntia ficus-indica (L.) Mill., in Agrigento Province, Sicily. In 1997, insects visiting flowers were sampled during May–June (the first bloom) and July (the second bloom, induced by the “scozzolatura” practise). More than 50 insect species belonging to 10 orders were collected in May–June, while only five species of Hymenoptera Apoidea were collected in July. The quality of fruits arising from the second bloom showed that Hymenoptera alone were able to guarantee effective pollination. To verify the role of insects in pollination in 1996 (during …
Fauna Europaea: Hymenoptera - Apocrita (excl. Ichneumonoidea)
2015
Fauna Europaea provides a public web-service with an index of scientific names (including important synonyms) of all living European land and freshwater animals, their geographical distribution at country level (up to the Urals, excluding the Caucasus region), and some additional information. The Fauna Europaea project covers about 230,000 taxonomic names, including 130,000 accepted species and 14,000 accepted subspecies. This represents a huge effort by more than 400 contributing specialists throughout Europe and is a unique (standard) reference suitable for many users in science, government, industry, nature conservation and education. Hymenoptera is one of the four largest orders of inse…

Cultural adaptation of the Smiling is Fun program for the treatment of depression in the Ecuadorian public health care system: A study protocol for a…
2021
Background Depression is one of the world's major health problems. Due to its high prevalence, it constitutes the first cause of disability among the Americas, where only a very low percentage of the population receives the adequate evidence-based psychological treatment. Internet-Based Interventions (IBIs) are a great alternative to reduce the treatment gap for mental disorders. Although there are several studies in low-and middle-income countries proving IBIs' feasibility and acceptability, there is still little evidence of the effectiveness in diverse social and cultural contexts such as Latin America. Methods Two studies will be described: Study 1 is focused on the cultural adaptation o…
Abeilles et plantes cultivées en Espagne : actualisation des données pour le melon, la pastèque et l’amandier
2021
[EN] Pollinators of most of the plants cultivated in the Mediterranean regions of Europe are still unknown. We provide new data and we review previously available information on bees (Apoidea) associated with three economically important crops in Spain: melon (Cucumis melo L.), watermelon (Citrullus lanatus (Thunb.) Matsum. & Nakai) and almond (Prunus dulcis (Mill.) D.A.Webb). We found that, overall, 98 bee species spanning four families visit flowers of the studied crop species, and 46 additional species were sampled within the crops with pan-traps. The bee assemblages visiting melon include 7–33 species, with moderate to high importance of small Lasioglossum (Halictidae) and of honey bee …
Influence of a humid zone on entomocoenosis diversity.
2017
The authors studied the insect diversity associated to humid and dry zones in the Caselli Nature Reserve (Pisa, Tuscany) in 2016 by using two Malaise traps. The average number of species and individual captures increased in the humid zone to about 118% for species and to 152% for individuals respectively. This richness increase was observed for some families of Coleoptera and Hymenoptera Aculeata and Apoidea. Surprisingly, a richness decrease of Lepidoptera (to 89% and 66% respectively for species and individuals) and Orthoptera (to 44% and 21% respectively for species and individuals) in the humid zone has been observed.
First records of pollinators of two co-occurring Mediterranean Apocynaceae
2011
This article presents results of a field survey of pollinators of two Apocynaceae, Periploca laevigata subsp. angustifolia (Labill.)Markgraf (Periplocoideae) and Caralluma europaea (Guss.) N.E.Br. Asclepiadoideae) co-occurring on Lampedusa Island, Mediterranean sea. Fifteen species within nine families of Diptera have been identified as pollinators of the two plants. The families involved are Tephritidae, Milichiidae, Trixoscelididae, cathophagidae, Anthomyiidae, Muscidae, Calliphoridae, Sarcophagidae, Rhinophoridae. Families of Muscidae and Sarcophagidae are the more represented, respectively with four and three species. P. laevigata subsp. angustifolia seems to have a broader spectrum of …
