abstract this study was carried out to compare disinfecting effects of nanosilver with other feed disinfectants on layer hen performance, immune system, gastrointestinal microflora and intestinal morphology. total of 90 layers (lsl) were divided into five groups consisting: 1-control, 2- formalin (200 ppm), 3- formaycin (200 ppm), 4- nanosilver in drinking water (7.5 ppm) and 5-nanosilver in f...
Miniature inverted-repeat transposable elements (MITEs) are prevalent in eukaryotic species including plants. MITE families vary dramatically and usually cannot be identified based on homology. In this study, we de novo identified MITEs from 41 plant species, using computer programs MITE Digger, MITE-Hunter and/or Repetitive Sequence with Precise Boundaries (RSPB). MITEs were found in all, but ...
a cross-sectional study was carried out to determine the prevalence and species of camel mange mite infestation in raya-azebo district, northern part of ethiopia. accordingly, three hundred and eighty-four camels were examined and mange mite infestation was detected on 64 of camels. only sarcoptes scabiei var. cameli was identified as the only mite species in all skin scraping samples collected...
Predators frequently compete with other species for prey but can also interact by preying on each other’s vulnerable stages. Because eggs and juveniles are more to this intraguild predation than adults, their survival will depend maternal strategies reduce risk. Recently, we reported that adult female predatory mites Gynaeseius liturivorus Ehara (Acari: Phytoseiidae) remaining at oviposition si...
BACKGROUND Few studies have investigated live house dust mite and mite allergen removal from clothing and bedding by washing machines. No studies have investigated the transfer of mites from infested to uninfested clothing and bedding during washing. OBJECTIVE The purpose of this study was to wash different types of clothing and bedding in residential washing machines to determine the live De...
The twospotted spider mite, Tetranychus urticae Koch, is a worldwide pest of numerous agronomic and horticultural plants. Sulfur fungicides are known to induce outbreaks of this pest on several crops, although mechanisms associated with sulfur-induced mite outbreaks are largely unknown. Studies were conducted during 2007-2009 in Oregon and Washington hop yards to evaluate the effect of timing ...
Understanding the impact of a pest species on a particular crop is critical for the success of a pest management program. Field studies were conducted to determine the effect of the twospotted spider mite, Tetranychus urticae Koch, on marketable yield of strawberries during the 2008/2009 and 2009/2010 growing seasons. Low, medium, and high mite infestation levels were established by initial ino...
The contact toxicity activity of an essential oil extracted from Acorus calamus (L.) (Acoraceae) was evaluated against the phytophagous spider mites Tetranychus urticae Koch and macfarlanei Baker & Pritchard (Acari: Tetranychidae) predatory mite Amblyseius longispinosus (Evans) Phytoseiidae). Adult mortality 24 h following application 5% (v/v) concentration exceeded 90% for T. macfarlanei. Appl...
component-resolved diagnosis (crd) using microarray technology has recently been introduced with the aim to improve diagnosis of allergy. the aim of this study was to compare performance of this allergen microarray to those of an established extract-based skin prick testing (spt). 45 patients with allergic rhinitis were studied (16 children and 29 adults). spt to dermatophagoides ...
biology of strawberry spider mite, tetranychus turkestani ugarov& nikolski was studied on cucumber, courgette and melon under laboratory conditions (30±1oc, 70±5% rh and 14:10 l: d). the mean female immature developmental times on cucumber, courgette and melon were recorded as 7.73±0.14, 8.27±0.24 and 9.54±0.36 days respectively. the values of immature death rate were 42.31, 48.93 and 63.63% on...
