Pome fruit growers and crop consultants have expressed concerns about the seasonal release performance of commercial codling moth mating disruption dispenser products. Because of these concerns, we developed a laboratory flow-through volatile collection system (VCS) for measuring the volatile release of the codling moth sex pheromone, codlemone, from commercially available hand-applied dispensers. Under controlled air-flow and temperature conditions, the released vapor was trapped onto a polyurethane foam adsorbent followed by solvent extraction, solvent reduction, and GC/MS determination. Method recovery and breakthrough validations were performed to demonstrate system reliability before determining codlemone release from commercial dispensers field-aged over 140 days. The volatile collection was carried out in a consistent manner among five dispenser types most commonly used by growers, so that direct comparison of performance could be made. The comparison showed differences in the amount of pheromone released and in the patterns of release throughout the season between dispenser types. The variation in release performance demonstrates the need for routine evaluation of commercially marketed mating disruption dispensers. We believe that the simple and cost-effective volatile collection system can assist pheromone dispenser manufacturers in determining seasonal dispenser performance before new products are introduced into the commercial market and in rapidly verifying dispenser release when field-aged dispenser efficacy is in question.  相似文献   

Molecular mapping of the fertility restoration locus Rf1 in sunflower and development of diagnostic markers for the restorer gene     

Barbara Kusterer  Renate Horn  Wolfgang Friedt 《Euphytica》2005,143(1-2):35-42

Fertility restoration by dominant nuclear genes is essential for hybrid breeding based on cytoplasmic male sterility (CMS) to obtain heterotic effects and high seed yields. In sunflower, only the PET1 sterility inducing cytoplasm has been used in commercial hybrid breeding until now. This particular male sterility was derived from an interspecific hybrid Helianthus petiolaris × H. annuus. For the recent work we used the segregating population RHA325(CMS) × HA342, based on the PET1 cytoplasm. Molecular markers were mapped within 1.1 cM around the restoration locus Rf1. At the distal side, the marker OP-K13_454 mapped at a distance of 0.9 cM and E32M36-155R at 0.7 cM from Rf1. At the proximal side the markers E44M70-275A, E42M76-125A and E33M61-136R were mapped at 0.1, 0.2, and 0.3 cM from the restorer locus, respectively. These markers provide an excellent basis for a map based cloning approach and for marker-assisted sunflower breeding.  相似文献   

Time pattern analysis of swimming activity and heart rate under the influence of chloramphenicol in carp (Cyprinus carpio L.) and rainbow trout (Salmo gairdneri R.)     

Martina Reide  Renate Siegmund 《Aquaculture (Amsterdam, Netherlands)》1989,80(3-4):315-324

In industrial fish production there is little information available about the effect of antibiotics on the fish organism. The swimming activity of carp and trout before, during and after treatment with chloramphenicol was observed. Due to the daily rhythmical organization of body function and closely correlated periods of activity and rest, a treatment with chloramphenicol at different times of the day has different effects on swimming activity. A significant increase in heart rate after treatment with chloramphenicol was detected as compared to the controls. These results suggest that treatment with chloramphenicol should be given during the last feeding.  相似文献   

IMAGING OF THE CANINE AND FELINE TEMPOROMANDIBULAR JOINT: A REVIEW     

Tobias  Schwarz  MA  Dr. Med. Vet.  Renate  Weller  Dr. Med. Vet.  Alison M.  Dickie  BVMS  MVM  Martin  Konar  Mag. Med. Vet.  Martin  Sullivan  BVMS  Phd 《Veterinary radiology & ultrasound》2002,43(2):85-97

The radiographic anatomy of the temporomandibular joint in the dog and cat is described in dorsoventral and oblique projections. The positioning for different oblique views in conventional radiography and technical details of computed tomography are reviewed. Typical radiographic features of craniomandibular osteopathy, dysplasia, luxation, subluxation, fractures, ankylosis, degenerative joint disease, infection, and neoplasia involving the temporomandibular joint are discussed.  相似文献

Lomustine and prednisone as a first-line treatment for dogs with multicentric lymphoma: 17 cases (2004-2005)     

Sauerbrey ML  Mullins MN  Bannink EO  Van Dorp TE  Kaneene JB  Obradovich JE 《Journal of the American Veterinary Medical Association》2007,230(12):1866-1869

OBJECTIVE: To assess response rate, median duration of response, adverse effects, and prognostic factors associated with concurrent administration of lomustine and prednisone as a first-line treatment for dogs with multicentric lymphoma. DESIGN: Retrospective case series. ANIMALS: 17 dogs. PROCEDURES: Medical records were reviewed. Information obtained included signalment, physical examination findings, results of diagnostic testing, stage and substage, initial lomustine and prednisone dosages, and total number of lomustine doses administered. RESULTS: Lomustine was administered at a median starting dosage of 67 mg/m(2), PO, every 21 days until 5 doses were given or disease progression was observed. Prednisone was administered at a median starting dosage of 1.8 mg/kg/d (0.82 mg/lb/d), PO, with dosage tapered during the first month of treatment. Six dogs had a complete response, and 3 had a partial response. Mean and median durations of response were 48.8 and 39.5 days, respectively. Median survival time was 111.2 days. In multivariate analyses, female sex and higher total lomustine dose were significantly associated with a longer disease-free inter-val. Neutropenia was the dose-limiting factor, with 4 dogs developing clinically important neutropenia 1 week after administration of a dose of lomustine. CONCLUSIONS AND CLINICAL RELEVANCE: Results suggest that concurrent treatment with lomustine and prednisone was well tolerated in dogs with multicentric lymphoma, but findings did not support the use of this combination for first-line treatment of affected dogs.  相似文献   

Metabolic and clinical traits in horses undergoing feed deprivation for elective orthopaedic surgery     

Reinprecht B  Hackl S  Reisinger R  Zickl M  Spona J  Stanek C  Zentek J 《Berliner und Münchener tier?rztliche Wochenschrift》2007,120(3-4):134-140

The objective of this study was to investigate some metabolic and clinical effects of feed deprivation in horses that were submitted for orthopaedic surgery. The effects of preoperative feed restriction were investigated in 20 horses submitted for elective orthopaedic surgery.The patients were fasted from 12 hours before until 4 hours after surgery. Serum free amino acids, glucose,free fatty acids (FFA), white blood cell counts, creatine kinase (CK) and aspartate aminotransferase (AST) were determined 24 hours before surgery, 2 hours after the end of anaesthesia and 24 and 72 hours after surgery. Besides, abdominal sounds, appetite, faecal quality and body temperature were examined. Serum free amino acids did not react homogenously, concentrations were partly increasing or decreasing. Plasma glucose and FFA increased after surgery and returned to their preoperative levels 72 hours after surgery. A significant rise of the segmented granulocytes occurred 24 hours after surgery, all other parameters of the leukogram did not exceed the physiological range. AST reached its highest activity 24 hours after surgery, whereas CK activities were highest at 2 hours after surgery. Abdominal sounds were significantly reduced until 24 hours after surgery, however, appetite was not depressed. Faecal quality was physiological after surgery. Mean body temperature stayed within the physiological range. In conclusion, a relatively short perioperative fasting period had significant effects on the metabolic traits in horses, however the effects on physiological functions were minor. The consequences of major surgical procedures need to be addressed in future studies.  相似文献   

RADIOGRAPHIC PROTOCOL AND NORMAL ANATOMY OF THE HIND FEET IN THE WHITE RHINOCEROS (CERATOTHERIUM SIMUM)          下载免费PDF全文

Foot pathology is a common and important health concern in captive rhinoceroses worldwide, but osteopathologies are rarely diagnosed, partly because of a lack of radiographic protocols. Here, we aimed to develop the first radiographic protocol for rhinoceros feet and describe the radiographic anatomy of the white rhinoceros (Ceratotherium simum) hind foot (pes). Computed tomographic images were obtained of nine cadaver pedes from seven different white rhinoceroses and assessed for pathology. A single foot deemed free of pathology was radiographed using a range of different projections and exposures to determine the best protocol. 3D models were produced from the CT images and were displayed with the real radiographs to describe the normal radiographic anatomy of the white rhinoceros pes. An optimal radiographic projection was determined for each bone in the rhinoceros pes focusing on highlighting areas where pathology has been previously described. The projections deemed to be most useful were D60Pr‐PlDiO (digit III), D45Pr45M‐PlDiLO (digit II), and D40Pr35L‐PlDiLO (digit IV). The primary beam was centered 5–7 cm proximal to the cuticle on the digit of interest. Articular surfaces, ridges, grooves, tubercles, processes and fossae were identified. The radiographic protocol we have developed along with the normal radiographic anatomy we have described will allow for more accessible and effective diagnosis of white rhinoceros foot osteopathologies.  相似文献
