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…
Three new species of phytoseiid mites from Kenya (Mesostigmata: Phytoseiidae)
1978
The following 13 species of predacious mites of the family Phytoseiidae are recorded from various plants in Kenya: Amblyseius albizziae sp. nov., A. kenyae sp. nov., A. natalensis Van der Merwe, A. lokele Pritchard & Baker, A. largoensis (Muma), A. rykei Pritchard & Baker, A. teke Pritchard & Baker, Typholdromus kikuyuensis sp. nov., T. magdalenae Pritchard & Baker, Phytoseius amba Pritchard & Baker, p. ferox Pritchard & Baker, Iphiseius degenerans (Berlese), I. gongylus Pritchard & Baker. The new species and the male of A. natalensis are described.
<i>Amblyseius fennicus</i> sp. n. (Acarina, Gamasina: Phytoseiidae) from Finland, with a key to the <i>A. americanus</i> group
2012
A new species is described belonging to the Amblyseius (s. str.) americanus group (Denmark & Muma, 1989). It was collected regularly from trunks of old trees in Finland. A key is given including the known species of the A. americanus group.
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…
