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.
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 …
Unpredicted ecological and ecosystem services of biodiversity. Spontaneous vegetation, hedgerows, and maple trees as useful landscape components to i…
2020
Abstract Rural landscapes have been dramatically simplified and reduced. Large mechanical machinery was adopted and most of the natural helps such as living tutors in the vineyards disappeared or were replaced by cement or steel pillars. In the same way, field margins and hedgerows have also become restricted and simplified. The vegetation in the rural landscape mosaic provides alternative food and overwintering places, maintaining the inestimable importance of biodiversity in providing unexpected ecological services in agroecosystems. An important example could be predatory mites both as species and population density, providing ecological service for biological control such as the two-spo…
Biological and life table parameters of Typhlodromus laurentii and Iphiseius degenerans (Acari, Phytoseiidae) fed on Panonychus citri and pollen of O…
2015
Typhlodromus laurentii and Iphiseius degenerans are two generalist phytoseiid mites, broadly spread in the Mediterranean area, especially in citrus orchards. In the present work we report results on various biological and life table parameters of the two phytoseiids, fed on pollen of Oxalis pes-caprae and various stages of the tetranychid Panonychus citri. Iphiseius degenerans had the shortest post embryonic development (6.53 days), the highest oviposition rate (1.83 eggs/female/day) and the shortest mean time between eggs laid (0.55 day) on Oxalis pollen, whereas the two food types did not influence these parameters in T. laurentii. However, Oxalis pollen showed a positive effect on the su…

Mites of the genus Typhlodromus (Acari: Phytoseiidae) from Southern France: combined morphological and molecular approaches for species identification
2019
Mites of the family Phytoseiidae are important predators for biological control applications. They occur naturally in ecosystems but their overall distribution is not completely known. This study presents results of surveys carried out in the south of France. It proposes the use of a combination of morphological and molecular approaches for species diagnosis. Eighteen species of the genus Typhlodromus are reported from southern France, of which nine belong to Typhlodromus (Anthoseius) and nine to Typhlodromus (Typhlodromus). Eight of these species are new to the French fauna. The mitochondrial DNA CytB gene from 85 specimens (18 species) and the 12S rRNA gene from 30 specimens (9 species) w…

Typhlodromus hellenicus sp. nov. is described and illustrated. The following 11 additional species were recorded:T. pyri Scheuten, sensu Abbasova,T. exhilaratus Ragusa,T. recki Wainstein,T. kerkirae Swirski and Ragusa,Amblyseius cinctutus Livshitz and Kuznetsov,A. stipulates Athias-Henriot, A. aff.finlandicus (Oudemans), A. aff.aberrans (Oudemans),A. potentillae (Garman),Phytoseiulus persimilis Athias-Henriot, andPhytoseius (Phytoseius) finitimus Ribaga.
Status of two cryptic species, Typhlodromus exhilaratus Ragusa and Typhlodromus phialatus Athias-Henriot (Acari: Phytoseiidae): consequences for taxo…
2006
Typhlodromus phialatus and T. exhilaratus are morphologically close species. Their differentiation is based on the shape of the insemination apparatus and on idiosomal setae length. However, the setae length values are often intermediate between these two species and do not allow accurate identification. Furthermore, the handful of differences in insemination apparatus shape are also questionable as a means of differentiation. Synonymy between these species has thus been questioned. Three experiments were carried out. Idiosomal seta length measurements, molecular tests and cross experiments were conducted for three populations, identified as T. exhilaratus and T. phialatus according to the …
Description of three new species oftyphlodromusscheuten from italy with redescription oftyphlodromus baccettiiLombardini (acari: phytoseiidae)
1978
Abstract Three new species of predacious mites from Italy, Typhlodromus ernesti , T. laurentii and T. pegazzani are described and illustrated. T. baccettii Lombardini, 1960 is redescribed.
Considerations on systematics of the Phytoseiidae (Acari: Mesostigmata), with definition of a new species group and description of a new species
2015
The authors debate some aspects of the classification of the Phytoseiidae, especially the subfamily Typhlodrominae. Within this taxon, the rhenanus group is the most numerous species group of Typhlodromus (Anthoseius), with 206 nominal species. Detailed observation of morphological characters of the species in this group showed a considerable variation, suggesting the presence of different natural lineages. The discovery of the new species here described, Typhlodromus (Anthoseius) sandrae Ragusa & Tsolakis n. sp., allowed the definition of the new porathi species group. Definition of the new species group, a dichotomous key as well as the description of the new species are given.
