Epidemiological knowledge on pathogens in ticks feeding on birds in Moldova is scarce. To reduce this gap of information, a total of 640 migrating and native birds of 40 species were caught from 2012 to 2015 and examined for the presence of ticks in the Republic of Moldova. Altogether, 262 ticks belonging to five tick species (Ixodes ricunus n = 24...
In the lower Dniester, polyploid females of the hybrid complex Cobitis taenia are a portion spawning species with asynchronous development of germ cells during the entire breeding period. The spawning season in this water basin begins in the second decade of May and ends in July. In the population, in parallel with females, hermaphrodite individual...
Corn is one of the major technical field crops in the Republic of Moldova, advantageous in bioecological and productive aspects, which is invaded annually by the harmful organisms with considerable parasitic impact. The phytosanitary control results, carried out annually and seasonally, comparatively in the corn plantations, notice a significant di...

As a result, a total of 563 beetle specimens, belonging to 98 species, 51 genera, and 15 families were collected. Among families recorded Carabidae was the one with...
The European legislative on the use of different control strategies against plant-parasitic nematodes, with particular reference to pesticides, is constantly evolving, sometimes causing confusion in the sector operators. This article highlights the nematode control management allowed in the C Zone of the European Union, which includes the use of ch...
The potato cyst nematode Globodera pallida is a major pest of the potato crop. Abamectin is a biological pesticide showing high nematicide activity, but its efficacy to control G. pallida has not been investigated to date. In this study, combination of different abamectin concentrations ranging from 1.125 to 36 µg/mL x exposure times from 24 to 384...
A pot trail and field observations were carried out to assess the pathogenicity of the cyst nematode Heterodera crucifere on cabbage plants (Brassica oleoracea). In the pot experiment H. cruciferae cysts were extracted by the Fenwick can from a soil heavily infested (64 eggs and J2/mL soil) collected from a field in which cabbage plants showed stun...
Progressive generation of total joint implant‐derived wear particles is one of the major risk factors in development of peri‐prosthetic osteolysis especially in the aging society. It is commonly accepted that macrophages predominantly drive the inflammatory response to wear debris particles. Among various surface receptors that activate the macroph...
Prutul de Jos Natural reserve located in the Cahul region of the Republic
of Moldova is a protected area of importance for flora and fauna and presents
a favorable place for migratory bird species. The mosquito surveys have been
conducted in this area since 2011 using CDC traps and dipping techniques. The
mosquito larvae were sampled in ground pool...
The present study documents three specimens of Benthophiloides brauneri from the River Dniester. It is one of the rarest freshwater fishes in Europe, living along the western coast of the Black and Asov Seas, but these new records are 200 river km from the coast. We discuss whether the species has recently started to establish inland populations or...
Background: Over the last two decades, a significant spread of dirofilariasis has been observed in eastern and
central Europe. However, data on the circulation of Dirofilaria spp. in Moldova were absent although direct
neighbor states reported high incidence rates of human dirofilariasis.
Methods: Daily mean temperature data were used to calculate...
Tatianaerhynchites aequatus (L.) (Coleoptera: Rhynchitidae), is an economically important pest species of fruit crops (Rosaceae). This study investigates population genetic structure of T. aequatus at the crossroads of biogeographic regions in Eastern Europe. To estimate gene flow and genetic variation, we sequenced a 794-bp fragment of the mitocho...
The present paper describes some peculiarities of the growth and reproduction of Carassius auratus s. latofrom the ecosystems of Lower Prut and Beleu Lake. This taxon is characterized by asynchronic development of oocytes and lying of three portions of eggs during the reproductive cycle. The histological analysis of the ovaries of Carassius auratus...
Phytoparasitic nematodes can cause severe yield losses to numerous vegetables therefore it is necessary their control. To evaluate the efficacy of two essential oils (EOs) isolated from Thymus vulgaris and Cinnamomum camphora in the control of the potato cyst nematode Globodera rostochiensis an in vitro experiment (hatching test) was carried out. B...
A countrywide field survey of immature mosquitoes was conducted in Moldova with the aim to evaluate the Culicidae species composition in different larval habitats and their distribution in the country.

The diversity and state of the benthic invertebrate communities from the Pruth River (within the borders of the Republic of Moldova) has been investigated during May of 2012-August of 2013. Twelve sampling stations have been chosen along the river, including Costeşti-Stânca reservoir. During the given period 159 taxa of the benthic macroinvertebrat...
Nematode faunal responses were studied under long-term, continuous sugar beet and crop rotations without fertilizer and with the combined application of manure with mineral fertilizers. Differences attributable to the different treatments were assessed in terms of abundance, species diversity of nematode communities, and functional guilds combining...
European Community on the use of pesticides on agricultural crops and according to the necessity to find new control methods at low environmental impact, a pot experiment in glasshouse on tomato was undertaken to verify the efficacy of soil ozonated water treatments against the root-knot nematode Meloidogyne incognita. Moreover, histological observ...
The present study was conducted to identify the microbial flora of pest weevils Sciaphobus squalidus (Gyll.), Tatianaerhynchites aequatus (L.) and Byctiscus betulae L., which may provide novel approaches for insect biocontrol.

Prut is the second largest river in Moldova. It takes its beginning from the South-East side of Goverla peak, 15 km South-Southwest of Vorokhta village in the woody Carpathian mountain massif Cernogora. The total length of the river is 967 km, in Moldova’s borders—695 km, the catchment area is 27,540 km2; Prut waters pours in the Danube at 164 km f...
Characterizing the tick-borne microorganism communities of Ixodes ricinus (sheep tick) and Ixodes persulcatus (taiga tick) from the I. ricinus species complex in distinct geographical regions of Eastern Europe and European Russia, we demonstrated differences between the two ticks. Taiga ticks were more frequently mono- and co-infected than sheep ti...
The mosquito fauna of the Republic of Moldova is poorly known. In an effort to
understand the Culicidae fauna better, mosquito collections have been conducted between early April and
middle November from 2008 to 2012. A total of 10,923 larval specimens and 8,246 adults were collected from
20 regions of Moldova. Altogether 36 species have been recor...
