New records of phytoseiid mites from Italy, with description of a new species and a redescription of other two (Parasitiformes, Phytoseiidae)
2020
The Italian phytoseiid fauna consists of 91 valid species. Eighteen of them were described as new species from materials collected in various Italian localities. In the present paper we report nine new records from the Italian fauna and describe the new species, Neoseiulus mediterraneus belonging to the subfamily Amblyseiinae. Complementary descriptions of two rare species, namely: Typhlodromus (Anthoseius) singularis and Typhlodromus (Typhlodromus) knisleyi, were also added.
LE SOSTANZE DI ORIGINE VEGETALE NEL CONTROLLO DEGLI ACARI FITOFAGI E GLI EFFETTI COLLATERALI SUI FITOSEIDI
2016
I metaboliti secondari con caratteristiche biocide presenti in molte piante, possono rappresentare una buona scelta per il controllo delle popolazioni dei fitofagi nei processi agricoli ecocompatibili. In particolare nelle coltivazioni gestite in regime di agricoltura biologica o biodinamica, il controllo degli acari fitofagi risulta attualmente legato solo a tecniche di controllo biologico o tecniche colturali con risultati non sempre soddisfacenti. Nella presente revisione vengono riportate notizie sull’azione di diversi estratti vegetali nei confronti di acari fitofagi, nonché notizie sugli effetti collaterali di questi estrati nei confronti di alcune specie di acari predatori.

Generic concept of the phytoseiids (Acari: Phytoseiidae) according to Athias-Henriot
2010
The economic importance of the Phytoseiidae motivated many scientists to work on the systematics of this family. One of them was the French acarologist Claire Athias-Henriot. In her first work, she tackled the question of supraspecific groupings within this family from an evolutionistic point of view, and suggested a system for numbering dorsal shield setae, that could be applied to both hypotrichous and holotrichous forms. She also looked for other characters, such as the ratios of the distance between the insertions of some setae on dorsal and sternal shields, the presence of macrosetae on legs, and the length/width ratio of the ventrianal shield. Following Dosse (1957; 1958) who used the…
