Biology and harmfulness of Planococcus vovae (Nassonov) (Hemiptera: Pseudococcidae) in Belgrade area

Planococcus vovae (Nassonov) (Hemiptera: Pseudococcidae) is an important pest on plants of the family Cupressaceae. Its numerous populations have been present in recent years on Juniperus spp. in Belgrade. Feeding by sap-sucking on all aboveground plant organs, it causes growth stagnation, chlorosis, drying of needles and branches, and even of entire plants under heavy infestation. Additionally, the scale excretes large quantities of honeydew, on which sooty mold develops, reducing photosynthesis and causing faster plant deterioration. Throughout 2007 and 2008, P. vovae was recorded on Juniperus spp. in 12 localities in Belgrade, and on Thuja sp. in a single locality. The pest was found to develop three generations per year and overwinter on branches at the egg or second instar stages. The first generation adults were observed at the end of May, the second generation at the beginning of August, while the third generation was recorded at the beginning of October. Different overwintering modes, and variable oviposition, embryonic and larval development periods led to an overlapping of generations and continuous presence of all developmental stages on plants. In different localities the infestation of plants varied in abundance from a few individual specimens to very large colonies. The highest infestation intensity was recorded in the localities Bezanija, Dorcol and Vozdovac. The predatory species Chrysoperla carnea (Stephens) (Neuroptera: Chrysopidae) and Nephus bipunctatus (Kugelann) (Coleoptera: Coccinelidae) were found in the scale colonies. Regarding N. bipunctatus, this was its first record as a new species in the Serbian fauna.

New data on spider fauna from northern Serbia

During two years of research on the epigeic fauna in agroecosystems of northern Serbia, which was conducted as a part of SEE-ERA NET PLUS project no. 51, 5488 spider specimens were collected at three fields with oilseed rape (Brassica napus var. oleifera), turnip rape (Brassica rapa x chinensis) and winter wheat (Triticum aestivum) as subsequent crop at Stari Zednik (Vojvodina). A total of 62 species from 15 families were identified. Pardosa agrestis and Xysticus kochi were the dominant species in the studied fields. Spider families with significant presence were Lycosidae, Linyphiidae, Thomisidae, Gnaphosidae, Theridiidae and Philodromidae. Seven species are new to the spider fauna of Serbia.

New records of the tribe Bryobiini berlsese (Acari: Tetranychidae: Bryobiinae) from Serbia, with notes about associated predators (Acari: Phytoseiidae)

This paper gives an overview of the present knowledge and some new faunistic and zoogeographic data of the insufficiently researched tribe Bryobiini in Serbia. In Serbia, this group of mites is represented by eight species, including four species new to Serbian fauna: Bryobia angustisetis Jakobashvili, B. lagodechiana Reck, B. ulmophila Reck and B. vasiljevi Reck. New data on host plant species and families have also been obtained - two new host plant species for B. angustisetis, two host plant species and two host plant families for B. graminum, one host plant species for B. lagodechiana, four host plant species and one host plant family for B. rubrioculus, two host plant species and one host plant family for B. ulmophila, and one host plant species for B. vasiljevi. This overview was supplemented with data on the other groups of leaf-inhabiting mites that coexist with Bryobiini species. Statistical analysis of interspecific association was done to determine the role of 15 associated predatory mite species belonging to the families Phytoseiidae, Anystidae and Trombidiidae.

Description of Preadult Stages (Protonymphs and Deutonymphs) of Discourella Radnaensis (Willman, 1941) Species (Acarina: Anactinotrichida: Uropodina)

Description of Preadult Stages (Protonymphs and Deutonymphs) of Discourella Radnaensis (Willman, 1941) Species (Acarina: Anactinotrichida: Uropodina) Discourella radnaensis species was described by Willmann from Slovenia, Radna city in 1941, the holotype being female. Since then, the species has not been collected, probably because Uropodina faunal studies in the Balkans were very few. Acarologic material was collected in Serbia, Djerdap National Park, Mount Veliki Strbac (768 m altitude), from litter of mixed deciduous forest and the bark of the decomposing trunk of deciduous trees. In addition to a female, individual protonymphs and deutonymphs were collected. Discourella radnaensis species is thus recorded for the first time in the fauna of Serbia, and pre-adult stages (protonymphs and deutonymphs) are described for the first time in literature.

Preliminary list of horse flies (Diptera, Tabanidae) of Serbia

Thirty six species of horse flies (Tabanidae) were previously known from Serbia (Europe). The present faunistic study of horse flies (Tabanidae) has resulted in the recording of the 4 new species Atylotus fulvus (Meigen, 1804); Tabanus miki Brauer in Brauer and Bergenstamm, 1880; Tabanus unifasciatus Loew, 1858; and Heptatoma pellucens (Fabricius, 1776), in the fauna of Serbia. The genus Heptatoma Meigen, 1803 is cited for the first time in the fauna of Serbia. 40 species are currently known from Serbia, belonging to nine genera. The fauna can be considered relatively poorly studied. Most of the species belong to the Boreal-Eurasian type of fauna 23, followed by the South European group with 8 species, the Mediterranean group with 6 species, European group with 2 species and Central European group with 1 species.

Predators and parasitoids of Cacopsylla pyri (L.) (Hemiptera: Psyllidae) in Serbia

The presence of C. pyri and its natural enemies was studied in both treated and untreated pear orchards in Serbia from 2005 to 2009. Five parasitoid and 21 predator species were identified as present on a considerable number of sites. The following parasitoid species were found: Prionomitus mitratus (Dalman), Psyllaephagus procerus Marcet, Syrphophagus ariantes (Walker), Syrphophagus taeniatus (F?rster) and Tamarixia sp. In the study, the species Psyllaephagus procerus, Syrphophagus ariantes and Tamarixia sp. were for the first time identified as parasitoids of C. pyri and as new species in the Serbian fauna. Among the parasitoids determined, Prionomitus mitratus predominated. Of the predators, the following species in four orders were registered: Dermaptera [Forficula auricularia Linnaeus (Forficulidae)], Heteroptera [Anthocoris nemoralis (Fabricius), Anthocoris nemorum (Linnaeus), Orius (Heterorius) minutus (Linnaeus), Orius (Heterorius) niger Wolff (Anthocoridae), Campylomma verbasci (Mayer-D?r), Deraeocoris (Deraeocoris) ruber (Linnaeus) and Deraeocoris (Knightocarsus) lutescens (Schilling) (Miridae)], Neuroptera [Chrysopa pallens Rambur, Chrysoperla carnea (Stephens), Chrysopa sp. (Chrysopidae)], and Coleoptera [Coccinella septempunctata Linnaeus, Adalia bipunctata Linnaeus, Adalia decempunctata (Linnaeus), Hippodamia tredecimpunctata (Linnaeus), Hippodamia variegata (Goeze), Propylea quatuordecimpunctata (Linnaeus), Calvia (Anisocalvia) quatuordecimguttata (Linnaeus) (Coccinellidae), Cantharis rustica Fall?n, Rhagonycha fulva (Scopoli) and Rh. testacea (Linnaeus) (Cantharidae)]. Of the predators determined, 12 species were registered for the first time as predators of C. pyri in Serbia, while C. rustica, Rhagonycha fulva and Rh. testacea have so far been known neither in Serbia nor in the world as predators of pear suckers.

New thrips species (Insecta: Thysanoptera) for the Serbian fauna

112 species have been listed in the last published check-list of thrips in Serbia. In this paper we introduce three new thrips species for this country. Orothrips priesneri , an aeolothripid species, has a discontinuous Mediterranean distribution. In Serbia it was found at several localities along the course of the Danube, a region with a warm, submediterranean influence. Its general distribution pattern makes its presence in Serbia unexpected. The hygrophilous species Iridothrips iridis was collected on the leaves of Iris pseudacorus in the vicinity of Grocka, near Belgrade. Platythrips tunicatus , which is widespread in Europe, is an oligophagous species related especially to plants from the genus Galium .
