Emine Çıkman  Hasan Sungur Civelek 《Phytoparasitica》2005,33(4):391-396

In a study carried out during 2002 and 2004 in Diyarbakıir and Mardin provinces, southeast Turkey, specimens were collected twice a month from cultivated and non-cultivated plants. Sixteen leafminer (Diptera: Agromyzidae) species were identified. Among them,Agromyza abiens Zetterstedt, 1848;Napomyza elegans (Meigen, 1830);Phytoliriomyza dorsata (Siebke, 1864); andPhytomyza aquilonia Frey, 1964 are new records for the Turkish leafminer http://www.phytoparasitica.org posting July 24, 2005.  相似文献

Creating and Consolidating Locally Managed Irrigation in Turkey: the National Perspective     

Mark Svendsen  D. Hammond Murray-Rust 《Irrigation and Drainage Systems》2001,15(4):355-371

The Turkish program of irrigationmanagement transfer has gained worldwidecelebrity for its speed and effectiveness. This paper describes the program brieflyand assesses its effectiveness from anational perspective. The assessmentincludes changes in staffing levels,operational costs, service fee levels, andcost recovery from farmers. A companionpaper examines impacts at the local leveland looks specifically at changes in systemperformance.  相似文献

A survey of the Eriococcidae (Hemiptera: Coccoidea) of Ankara Province,Turkey     

S.?ülgentürkEmail author  M.?B.?Kaydan  S.?Toros  M.?O.?Gürkan 《Phytoparasitica》2003,31(5):442-445

The Coccoidea of cultivated and non-cultivated areas of Ankara Province, in central Anatolia, Turkey, were surveyed between 1999 and 2001. Eleven species of Eriococcidae were collected, of which nine are new records for Turkey:Acanthococcus greeni Newstead,A. micracanthus Danzig,A. munroi Boratynski,A. roboris (Goux),A. zernae Tereznikova,Rhizococcus cingulatus (Kiritchenko),R. cynodontis (Kiritchenko),R. herbaceus Danzig andR. pseudinsignis (Green). http://www.phytoparasitica.org posting Sept. 30, 2003.  相似文献   

Natural parasitism of<Emphasis Type="Italic">Chrysoperla carnea</Emphasis> by hymenopterous parasitoids in cotton-growing areas of Çukurova,Turkey     

K.?KarutEmail author  C.?Kazak  A.?Arslan  E.??ekero?lu 《Phytoparasitica》2003,31(1):90-93

A 4-year study of parasitoids attackingChrysoperla carnea (Stephens) in the cotton fields of Çukurova, Turkey, revealed the activities of three principal taxa:Telenomus sp. nr.suvae attacks the eggs ofC. carnea: Catolaccus sp. andBaryscapus sp. are larval and pupal parasitoids, respectively. In general, percent egg parasitism increased starting from the second half of June and into July, then decreased until the beginning of August before rising again at the end of growing season. During the early season, weekly parasitism was found to be as high as 94%. Overall, seasonal egg parasitism varied between 13.6% and 62.0% among all study sites. According to the results of a one-year field study at Hac?ali, total larval and pupal parasitism was found to be 12.5% and 55.6%, respectively. Therefore, different factors influencing the effectiveness of the generalist predatorC. carnea against cotton pests, and the differential effects of cotton treatments on both host and parasitoids, need to be evaluated.  相似文献   

Note: Molecular identification of three entomopathogenic nematodes from turkey by PCR-RFLP of the ITS regions     

I. Alper Susurluk  Umut Toprak 《Phytoparasitica》2006,34(1):17-20

Molecular identification methods are widely used for the classification of organisms worldwide. Entomopathogenic nematodes are the most often isolated insect parasitic nematodes in the tropical and subtropical regions. In our investigation, PCR-RFLP (Polymerase Chain Reaction — Restriction Fragment Length Polymorphism) of the ITS region (Internal Transcribed Spacer) on the ribosomal (r) DNA of three entomopathogenic nematodes isolated from Ankara, Turkey, was analyzed for identification. The ITS region of rDNA was amplified by PCR and then digested with the following nine restriction enzymes: Alu I, Dde I, Hae III, Hha I, Hind III, Hinf I, Hpa II, Rsa I and Sau 3AI. The amplified and restricted sequences of the ITS regions were separated by agarose gel electrophoresis and the RFLP patterns of these three species were shown in this study. According to our results, these species were identified asSteinernema feltiae, Steinernema carpocapsae andHeterorhabditis bacteriophora. http://www.phytoparasitica.org posting Nov. 4, 2005.  相似文献

Effects of different ecological and silvicultural factors on beetle catches in the Turkish fir (<Emphasis Type="Italic">Abies bornmülleriana</Emphasis> Mattf.) ecosystems     

Oktay Yıldız  Derya Eşen  Süleyman Akbulut 《Journal of pest science》2007,80(3):145-150

To study the bark beetle attacks on Turkish fir stands and to determine the principle site and stand factors influencing beetle attacks, trap log method was used in the Western Black Sea Region of Turkey. The study was carried out in ten different locations prior to flying time in February 2003. On each experimental plot, three healthy fir trees with 30–50 cm diameter and 200 m apart were cut down with a chainsaw. From each sampling tree, needles were sub-sampled for determination of specific leaf-area and macro-nutrient concentrations. In addition, on each experimental plot, crown closure, basal-area, and stand density were measured. To determine the bulk density and nutrient concentrations of the soil, samples were taken around trees on each plot. The relationship between measured stand variables, the number of beetle species and beetle populations were evaluated using correlation and stepwise multiple regression procedure. Eight different species belonging to four different families from Coleoptera were identified in examining the trap logs. Six of these eight species (Pissodes piceae Illig., Pissodes notatus Fabr., Cryphalus piceae Ratz., Pityophthorus pityographus Ratz., Xyloterus lineatus Oliv., Pityokteines curvidens Germ.) were identified as harmful beetles (HB). The other two (Thanasimus formicarius L. and Rhizophagus dispar Payk.) were identified as predator species. The analysis showed that the total number of HB increased as the site’s slope and needle specific leaf area increased. However, as needle N concentrations increased, HB population decreased. Increased Ca concentration in fir needle reduced total insect attack.  相似文献   

Assessment of Aspergillus fumigatus burden in lungs of intratracheally-challenged turkeys (Meleagris gallopavo) by quantitative PCR,galactomannan enzyme immunoassay,and quantitative culture     

《Comparative immunology, microbiology and infectious diseases》2014,37(5-6):271-279

Aspergillus fumigatus remains a major respiratory pathogen in birds and treatment is still difficult. We challenged different groups of few-day-old turkeys via intratracheal aerosolisation with increasing concentrations (10⁵ up to 10⁸) of conidia using a MicroSprayer^® device. The fungal burden was assessed by real-time PCR, galactomannan dosage, CFU counting and histopathological evaluation in order to provide a comparison of these results within each inoculum groups. Significant mortality, occurring in the first 96 h after inoculation, was only observed at the highest inoculum dose. Culture counts, GM index and qPCR results on the one hand and inoculum size on the other hand appeared to be clearly correlated. The mean fungal burden detected by qPCR was 1.3 log₁₀ units higher than the mean values obtained by CFU measurement. The new model and the markers will be used to evaluate the efficacy of antifungal treatments that could be used in poultry farms.  相似文献
