Tidskriftsartikel (refereegranskat)abstract
- A new species of Epuraea, Epuraea sutcuimamun Avgin, Lason andamp; Audisio sp. n., from southern Turkey (Taurus Chain) was identified using morphological analyses. This species is a member of a circum-Mediterranean endemic group of sap beetles, the Epuraea latipes species group of the Dadopora lineage, which are mostly associated with cedar (Cedrus spp.) forests. Herein, the new species is described, the previously unknown association of the little-known Epuraea subparallela Grouvelle 1896 with meso-xerophilous oaks is reported, and some new records from southern Turkey (Taurus Chain) are listed for the latter species (previously only known from the Nur Mts. in SE Turkey, Osmaniye and Iskenderun provinces). An identification key to species of Dadopora lineage is also provided. Finally, the main palaeogeographic events affecting the Miocene to Holocene dispersal and evolution of species/populations of the Dadopora lineage on cedars and oaks, and the coincident distributional dynamics of Western Palaearctic Cedrus populations throughout the Mediterranean Basin, are discussed.

Impacts of moose (Alces alces) at different simulated densities on eco-morphological groups of soil mesofauna
- 2010

Ingår i: Entomologica Fennica. - 0785-8760. ; 21, s. 168-180

Tidskriftsartikel (refereegranskat)abstract
- We experimentally tested the impact of browsing, defecation and urination corresponding to four different levels of moose population density on abundance and number of eco-morphological groups of soil mesofauna in a Swedish boreal forest. The study was carried out in three fenced exclosures representing different levels of productivity (from nutrient-rich to nutrient-poor). Moose impact on soil communities was evaluated by analysing abundance, richness and diversity of mesofaunal groups, and by means of a multi-taxa index based on ecomorphological groups, the Biological Soil Quality index (QBS). There was a negative impact of high moose densities on the abundance and richness of soil mesofauna. Furthermore, low-moderate moose densities had a positive impact on abundance and number of eco-morphological groups. We conclude that moose can have a large impact on soil-living mesofauna, and therefore probably soil decomposition processes and biological soil quality, in young boreal forest stands.

The composition of the egg-parasitoid guild of the golden egg bug, Phyllomorpha laciniata (Heteroptera: Coreidae), in Spain
- 2012
-
Ingår i: Entomologica Fennica. - 0785-8760. ; 23, s. 95-101
-
Tidskriftsartikel (refereegranskat)abstract
- The golden egg bug (Phyllomorpha laciniata (Villers)) is a phytophagous insect with an unusual reproductive system. Females use the bodies of conspecifics, both males and females, as oviposition substrates. In addition, a varying fraction of the eggs is laid on the food plant. Egg carrying on conspecifics increases offspring survival. Predators and, especially, hymenopteran parasitoids are the main cause of egg mortality. So far, only the wasp Gryon bolivari (Giard) (Hymenoptera: Scelionidae) has been reported as an egg parasitoid of P laciniata in several Mediterranean populations. In this study, three new egg-parasitoid species are recorded from P laciniata: the primary solitary parasitoids Gryon monspeliense (Picard) and Telenomus sp. (Hymenoptera: Scelionidae), and the facultative hyperparasitoid Ooencyrtus telenomicida (Vassiliev) (Hymenoptera: Encyrtidae). All of these parasitoids have been reared from host eggs being carried by conspecific bugs. We discuss the taxonomy and biology of the individual parasitoid species, as well as ecological and evolutionary aspects of the interactions in this host-parasitoid system.

Habitat associations and occupancy patterns of burnet moths (Zygaenidae) in semi-natural pastures in Sweden
- 2004
-
Ingår i: Entomologica Fennica. - 0785-8760. ; 15:2, s. 91-101
-
Tidskriftsartikel (refereegranskat)abstract
- Burnets were surveyed in 100 semi-natural pastures in the province of Ostergotland, southeastern Sweden. We analysed the presence/absence of burnets in relation to habitat characteristics, and species richness of butterflies and plants. Five species were found (Adscita statices, Zygaena osterodensis, Z. viciae, Z. filipendulae and Z. lonicerae), all occurring in 33%-36% of the localities. Among these, four are nationally red-listed. More species were found on (1) large semi-natural pastures, compared with small, (2) low- to medium-grazed semi-natural pastures, compared with heavily grazed, and (3) open semi-natural pastures, compared with wooded. A. statices and Z. viciae had a higher frequency of occupancy at localities surrounded by a large density of pastures, but the occurence of the other species did not rely on this variable. The number of burnet species per locality was positively correlated with the number of butterfly species, and slightly positively correlated with species richness of plants. The difference in species richness among burnets, butterflies and plants may be explained by different responses to grazing pressure; the species richness of burnets and butterflies peaked in localities with a low grazing pressure, while species richness of plants was unaffected by grazing. As burnets are easily surveyed and indicate a high butterfly-species richness, they may be suitable indicators of species richness of pastures. As uniform management with heavy grazing is detrimental for burnets and for many butterflies, it should be avoided at localities with a species-rich fauna.

Somatic and population adaptations of Polysarcus denticauda (Orthoptera) in extreme altitudes
- 2009
-
Ingår i: Entomologica Fennica. - 0785-8760. ; 20, s. 207-214
-
Tidskriftsartikel (refereegranskat)abstract
- Altitudinal preferences, somatic and population adaptations in different ecological conditions were analysed in flightless bush-cricket species Polysarcus denticauda (Charpentier, 1825). Altitudinal analysis was performed in GIS software (more than 60 sites in Slovakia, Central Europe). Seasonal occurrence and population density were recorded in selected sites. To compare differences, absolute values of measurements (length of body, hind femur and tibia, cerci and weight) and Body Condition Index were taken from males. Study species prefers mesophilous montane up to alpine meadows in higher elevations (over 600 in a.s.l.). The development started over one month earlier in lowlands and populations reached several fold higher density there. Males from lowlands had body parameters significantly bigger apart from cerci. Cerci were significantly longer in males from mountains. However, males of the same size were significantly heavier in higher attitudes. In conclusion, refuges of montane meadows ecosystem support species survival nowadays.

Two new species of Allodia subgenus Brachycampta Winnertz from Norway and Sweden (Diptera : Mycetophilidae)
- 2007
-
Ingår i: Entomologica Fennica. - 0785-8760. ; 18:1, s. 17-23
-
Tidskriftsartikel (refereegranskat)abstract
- Allodia (Brachycampta) huggerti sp. n. from Sweden and Allodia (Brachycampta) rindeni sp. n. from Norway and Sweden are described based on a few adult males. Detailed illustrations of their terminalia are provided. The A. (B.) barbata species group is defined for species of which both dorsal and ventral branches of the male gonostylus are reduced to slender lobes, and the two new species both belong in this species group. They differ from other species in the species group primarily by the structure of the apicoventral corners of the gonocoxite, by the shape of the hypandrial lobe, and in details of the gonostylus. The new species seem to be most closely related with each other and further to A. (B.) racemosa Zaitzev, 1992 known from Alaska. The new species are named in memory of their collectors, the late dr. Lars Huggert (1942-2003) and the late Helge Rinden (1967-1999).

Tidskriftsartikel (refereegranskat)abstract
- The first European record of Exechia inaperta Ostroverkhova, 1979 is presented and its morphological difference from the allied E. exigua Lundstrom, 1909 is discussed. Diagnostic characters and detailed figures of male terminalia are given for both species. The new finding of E. inaperta in Estonia indicates a possibly disjunct Euro-Siberian distribution pattern of the South-Taiga, also observed in several other species of fungus gnats.

Mesopolobus incultus auct. (Hymenoptera : Pteromalidae) contains two distinct species: Mesopolobus incultus (Walker, 1834) and Mesopolobus amyntor (Walker, 1845)
- 2018
-
Ingår i: Entomologica Fennica. - 0785-8760. ; 29:4, s. 175-184
-
Tidskriftsartikel (refereegranskat)abstract
- Mesopolobus incultus auct. is hypothesized to consist of two different species, M. amyntor (Walker) and M incultus (Walker). This hypothesis is supported by molecular (cytochrome c oxidase subunit I, i.e. COI), morphological and biological data. Mesopolobus amyntor is a primary parasitoid of Mecinus pascuorum (Gyllenhal) and M. labilis (Herbst) (Coleoptera: Curculionidae) on Plantago lanceolata. Mesopolobus incultus is a primary parasitoid of Protapion fulvipes (Geoffroy) (Coleoptera: Apionidae) on Trifolium repens and T.pratense, and has also been inferred to act as a secondary parasitoid (hyperparasitoid) of Spintherus dubius (Nees) (Hymenoptera: Pteromalidae) or Bruchophagus gibbus (Bohe-man) (Hymenoptera: Eurytomidae). The results of this study lead to following nomenclatural changes: M. amyntor is removed from synonymy under M. incultus, and Pteromalus urgo, P. belesis and P. berecynthos, all described by Walker, are synonymized under M. amyntor. The species are diagnosed with characters illustrated.
