fauna of the the aphid parasitoids at southern parts of the zagros submountains, and their host associations have been investigated. a total of 24 parasitoid species were identified in association with 30 aphids on 36 host plant species, representing more than 80 tritrophic associations (parasitoid-aphid-plant). aphidius avenae haliday is newly reported from iran. generally, the area of souther...

One Health is an interdisciplinary collaboration that aims at mitigating risks to human health arising from microorganisms present in non-human animal species, which have the potential to be transmitted and cause disease in humans. Different degrees of scientific collaboration and sectoral integration are needed for different types of zoonotic diseases, depending on the health and associated ec...

Predicting outbreaks of zoonotic infections in reservoir hosts that live in highly fluctuating environments, such as Sin Nombre virus (SNV) in deer mice, is particularly challenging because host populations vary widely in response to environmental conditions and the relationship between field infection rates and abundance often appears to contradict conventional theory. Using a stage-structured...

Lice are small, wingless, minor ectoparasites of mammals and birds. More than 540  blood-sucking lice (Phthiraptera: Anoplura) have been described with each host having its own type of louse, suggesting the cospeciation of the lice species with their host. Among these, two lice species from two different genera infest humans: Pediculus humanus and Phthirus pubis (pubic “crab” l...

The Aras reservoir, located in the north-west of Iran, plays an important role in fisheries, drinking and agricultural water supplies and recreational activities in the region. This study was performed to characterize the seasonal fluctuations of phytoplankton communities and their relationship with environmental factors in the Aras reservoir from August 2013 to May 2014. Sampling was carried o...

the main diatomic structure-forming species of the zayandehrud reservoir was investigated by collecting samples from the surface, five, seven and 10 m depths from january 2011 to october 2012 along four linear transects. asterionella formosa hassall, cyclotella ocellata pantocsek and fragilaria crotonensis kitton were revealed as the three structure-forming species among diatomic algae in the r...

Background: An epidemiological study was carried out on the vector(s) and reservoir(s) of cutaneous leishmaniasis in rural areas of Kalaleh District, Golestan Province during 2006 2007. Methods: Totally 4900 sand flies were collected using sticky papers and were subjected to molecular methods for detection of leishmanial parasite. Results: Phlebotomus papatasi was the common species in outdoor ...

one species of eulophidae, oomyzus sokolowskii (kurdjumov), was collected from larvae of the diamondback moth, plutella xylostella (l.) (lep.: plutellidae). this parasitoid is a major gregarious larval-pupal endoparasitoid of p. xylostella that prefers ovipositing into host larvae but depositing its eggs in host prepupae too. this is the first report of the occurrence of this species from iran.

Numerous mammal species, including domestic and wild animals such as ruminants, dogs, cats and rodents, as well as humans, serve as reservoir hosts for various Bartonella species. Some of those species that exploit non-human mammals as reservoir hosts have zoonotic potential. Our understanding of interactions between bartonellae and reservoir hosts has been greatly improved by the development o...

2/3 of the reservoir surface area was approximately covered with dense populations of Myriophyllum, Ceratophyllum and Potamogeton species. The headwaters of the reservoir were considered as hard water and had both carbonatic and non-carbonatic hardness. When they were exposed to lentic condition of the reservoir and its intensive photosynthetic activities of macrophyte communities, the bicarbon...
