Tetranychus urticae is the most important pest on different crops worldwide. Search for endemic phytoseiid mites co-occurring with the above pest, which might be good candidates as biocontrol agents, represents the policy followed by most scientists in recent years. The aim of the present work was to assess the various biological and demographic parameters of Neoseiulus longilaterus, associated with T. urticae on weeds, in laboratory conditions using the latter tetranychid and pollen of Oxalis pes-caprae as food. The results showed a better performance of the predator on the prey as regards the postembryonic development (7.63 and 8.18 days for prey and pollen respectively) and the demograph…

First record ofTetranychus ludeniZacher (Acariformes: Tetranychidae) in Italy

2018

Tetranychus ludeni Zacher is reported here for the first time in Italy. It was found on some cultivated and spontaneous plants, often associated with Tetranychus urticae Koch. Four phytoseiid mites, widely distributed in the Mediterranean countries, Phytoseiulus persimilis Athias-Henriot, Iphiseius degenerans Berlese, Typhlodromus (Anthoseius) kerkirae Swirski and Ragusa, and Typhlodromus (Anthoseius) transvaalensis Nesbitt, were found associated with T. ludeni In Sicily. The morphological characters for the identification of the four Italian Tetranychus species are also reported.

On the identity of Neoseiulus fallacis (Garman 1948) (Parasitiformes, Phytoseiidae): redescription of the species and description of the new species …

2016

ABSTRACTNeoseiulus fallacis (Garman) is a broadly commercialised phytoseiid mite used in Integrated Pest Management (IPM) programmes especially in northern and southern America. However, its taxonomic status was, until now, equivocal because no redescription based on type material had ever been made. The authors redescribe N. fallacis from type material in Garman’s collection, designating the lectotype and paralectotypes for the species. Moreover, a new species of the fallacis complex, discovered among the fallacis type material, is described and named N. garmani sp. nov. in honour of Philip Garman.

Phytoseiid mites from Basilicata region (Southern Italy): species diversity, redescription of Typhloseiulus arzakanicus Arutunjan and a dichotomic ke…

2017

A survey of phytoseiid mites was carried out in the Basilicata region (Southern Italy) between 1976 and 2014 on wild and cultivated plants. A total of 38 species belonging to eleven genera and two subgenera were found on 59 plant species. The most common species was Euseius finlandicus (Oudemans) (39%) followed by Typhlodromus (Typhlodromus) exhilaratus Ragusa (32.2%), Kampimodromus aberrans (Oudemans) (27.1%), Typhlodromus (Anthoseius) cryptus (Athias-Henriot) (23.7%). Typhloseiulus arzakanicus (Arutunjan), found for first time in Italy, is redescribed here, while the male of this species is described for the first time. A dichotomic key of the species belonging to the genus Typhloseiulus …

Pilosella hoppeana subsp. sicula Di Grist., Gottschl. & Raimondo (Asteraceae), a new endemic subspecies from Sicily (Italy)

Candollea 71: 7–12. In English, English abstract. DOI : http://dx.doi.org/10.15553/c2016v711a2 Pilosella hoppeana subsp. sicula Di Grist., Gottschl. & Raimondo (Asteraceae), a new endemic subspecies from the Madonie and Nebrodi Mountains (Sicily, Italy), is described and illustrated. It is morphologically close to Pilosella hoppeana subsp. macrantha (Ten.) S. Braut. & Greuter, but the two subspecies can be distinguished by the indument on the bracts. Its morphology, distribution, ecology, taxonomic relat…

S-nitrosylation: An emerging post-translational protein modification in plants

2011

International audience; Increasing evidences support the assumption that nitric oxide (NO) acts as a physiological mediator in plants. Understanding its pleiotropic effects requires a deep analysis of the molecular mechanisms underlying its mode of action. In the recent years, efforts have been made in the identification of plant proteins modified by NO at the post-translational level, notably by S-nitrosylation. This reversible process involves the formation of a covalent bond between NO and reactive cysteine residues. This research has now born fruits and numerous proteins regulated by S-nitrosylation have been identified and characterized. This review describes the basic principle of S-n…

Resource profitability, but not caffeine, affects individual and collective foraging in the stingless beePlebeia droryana

2019

ABSTRACT Plants and pollinators form beneficial relationships, with plants offering resources in return for pollination services. Some plants, however, add compounds to nectar to manipulate pollinators. Caffeine is a secondary plant metabolite found in some nectars that affects foraging in pollinators. In honeybees, caffeine increases foraging and recruitment to mediocre food sources, which might benefit the plant, but potentially harms the colonies. For the largest group of social bees, the stingless bees, the effect of caffeine on foraging behaviour has not been tested yet, despite their importance for tropical ecosystems. More generally, recruitment and foraging dynamics are not well und…

Exploring the presence of pollutants at sea: Monitoring heavy metals and pesticides in loggerhead turtles (Caretta caretta) from the western Mediterr…

2017

Marine turtles are considered good sentinel species for environmental assessment because of their long lifespan, feeding ecology, habitat use and migratory nature. In the present study, we assessed presence of cadmium, lead and mercury, together with organic pollutants, both in fat and muscle tissue of 25 stranded loggerhead turtles (Caretta caretta) stranded along the Valencian Community coast (East Spain) (43.7±13.5cm). Mean concentrations of Cd, Pb and Hg were 0.04μg/g w.w., 0.09μg/g w.w. and 0.03μg/g w.w. in fat and 0.05μg/g, 0.08μg/g and 0.04μg/g in muscle, respectively. These measures indicate a relatively low mean heavy metal concentration, which may be explained by juvenile size and…
