Grass-associated fungi (grass symbionts) in the family Clavicipitaceae (Ascomycota, Hypocreales) are species whose host range is restricted to the plant family Poaceae and rarely Cyperaceae. The best-characterized species include Claviceps purpurea (ergot of rye) and Neotyphodium coenophialum (endophyte of tall fescue). They have been the focus of considerable research due to their importance i...
Previously only ten species of Hercostomus Loew were known to occur in Tibet, of which only two belong to the H. baishanzuensis group. Here the following six species of the H. baishanzuensis group are described as new to science: Hercostomus bisetus sp. nov., H. deltodontus sp. nov., H. flavus sp. nov., H. galonglaensis sp. nov., H. nuciformis sp. nov. and H. pailongensis sp. nov. A key to the ...
Background and purpose: Flies have a high diversity and are able to transmit many pathogens due to their adaptation and close relationship with humans. Therefore, this study was performed to identify the fauna of medically important flies in the city of Joybar in northern Iran. Materials and methods: This descriptive-analytical study was conducted twice a month in Juybar at selected sites, inc...
Two new species of Didicrum from Argentina are described and illustrated: Didicrum naimae and Didicrum letitiae, based on male and female specimens. Specimens were collected with Malaise traps located in Nahuel Huapi National Park, Patagonian region. Including the two new species of Didicrum, twelve are described from South America.
Although the movement of stable fly, Stomoxys calcitrans (L.), has been studied, its extent and significance has been uncertain. On a local scale (<13 km), fly movement occurs between host animals and resting sites to feed and mate, mainly at on-farm locations where herbivorous livestock regularly congregate. Small numbers emigrate from livestock congregation sites in search of other hosts and ...
Background and Aim: Some medically important species of Muscidae and Fanniidae families are among synanthropic flies and can be seen in human habitats therefore they can be mechanical vectors of different pathogenic microorganisms. Identification and determination of species of these flies is essential for any control program planning. This study was conducted to determine the faunal diversity ...
This is the first record for the subfamily Psychodinae from Ecuador and a new species belonging to genus Arisemus, A. triconnectus, is described.
Background and Aim: Sand flies are responsible for transmission of leishmaniasis, papatasi fever and carrion disease. Warning of sand fly population is the first step for the establishment of baseline data for the vector control operations of visceral leishmaniasis (VL). In order to attempt to the difference between species composition and bieocology of sand flies, the comparative research was...
Myiasis is always resulted by depositionof egg or young larvae of cyclorrhapha flies’ in live tissus of human or animals,which follows by their Development. Although the survival of mentioned larves is depended on existance of livestock and wild animals, the flies can be seen in parks, dairy farms and certain plants and also solid wasts waiting for proper hosts. The frequent study was carr...
No field failure of azinphosmethyl had been noticed in controlling codling moth from Oregon until 1989. However, in a study conducted by Moffitt et al. during 1986 to 1987, a codling moth population from Medford has been reported resistant to diflubenzuron. It was suspected that selection by other commonly used compounds was probably responsible for this resistance. We initiated our work in 198...
