Synganglia, salivary gland, midgut, ovary, fat body and muscle alone and in combination from the ixodid tick, Dennacentor variabilis (Say), or the argasid tick, Omithodoros parkeri Cooley, were incubated in vitro in separate experiments with L-[methyl-3H]methionine and farnesoic acid or with [1-14C]acetate. Life stages examined in D. variabilis were 3-72 hold (after eclosion) unfed nymphs, part...
The quantitative anatomical characteristics of Quercus variabilis virgin cork grown in Korea were observed by scanning electron microscopy and compared with suber reproduction from Portugal to obtain basic data for further utilization domestic resources Korean industries. Q. showed a smaller growth ring width higher latecork percentage than cork. proportion cells lenticular channels suber, wher...
خاصیت ضد میکروبی هشت گونه جلبک سبز- آبی (سیانوباکتر) تالاب انزلی به دو روش تقطیر در خلاء و مکانیکی ساده بر روی چند گونه باکتری بررسی شد. نتایج نشان داد که گونه های جلبکی anabaena sp.،anabaena variabilis ، anabaena flos-aquae وaphanizomenon flos-aquae برروی کاهش رشد باکتری استافیلوکوکوس اورئوس و گونه های anabaena flos-aquae و .anabaena oscillaroides بر روی کاهش رشد باکتری اشرشیاکلی مؤثر بودند....
Pratylenchoides camachoi n. sp. from rosemary (Rosmarinus officinalis L.) in Sierra De Cazorla in southeastern Spain is described and illustrated. Pratylenchoides camachoi n. sp. is a bisexual species characterized by a cylindroid, sometimes clavate-shaped, male tail with a uniquely shaped smooth, rounded terminus. Females are characterized by a short esophageal overlap and six lines in the lat...
An Ab molecule or a BCR that is able to bind multiple structurally unrelated Ags is defined as polyreactive. Polyreactive Abs and BCRs constitute an important part of immune repertoires under physiological conditions and may play essential roles in immune defense and in the maintenance of immune homeostasis. In this review, we integrate and discuss different findings that reveal the indispensab...
The experimental vector competence of five laboratory-reared ixodid tick species representing three genera [Amblyomma americanum (L.), Boophilus microplus (Canestrini), D. andersoni Stiles, D. occidentalis Marx, and D. variabilis (Say)] for Babesia equi (Laveran 1901) was evaluated by delayed transfer of male ticks from infected to susceptible equids or by infesting the latter animals with adul...
The present study was aimed to isolate a multiple herbicide resistant strain [(MHR)] of Anabaena variabilis exhibiting resistance against four common rice-field herbicides, viz., Arozin, Alachlor, Butachlor and 2,4-D. The multiple herbicide resistant (MHR) strain was isolated by spontaneous mutational techniques. Of the four spontaneously occurring mutants, Arozin resistant mutant (Ar-R) exhibi...
A state-wide survey was conducted in Florida during the 1997-99 hunting seasons to examine white-tailed deer (Odocoileus virginianus) and feral swine (Sus scrofa) for potential indigenous vectors of the rickettsial agent of heartwater, Cowdria ruminantium. A total of 504 white-tailed deer and 166 feral swine was examined from 30 wildlife management areas across the state. Amblyomma maculatum, a...
(1) Background: Oaks have achieved notoriety for sufficient levels of sympatric species richness allowing hybridization, thus generating substantial phenotypic variation. Leaf fluctuation asymmetry is an important attribute, as it reflects not only genetic variability but also buffering capacity. (2) Methods: We investigated the diversity four-oak (Quercus acutissima, Q. variabilis, fabri, and ...
