Zusammenfassung
Ceratitis capitata Wied. ist der wichtigste Schädling, der in Jordanien Citrus und Steinfrüchte befällt. Es wird ein Befall von 20–25% für Citrus, 91% für Pfirsich, 55% für Aprikose und 15% für Pflaume geschätzt.Populationsstudien wurden in den Jahren 1960 und 1961 in vier Gebieten durchgeführt. An Citrus traten vier Generationen auf, an Pfirsich, Aprikose und Pflaume zwei Generationen. Es wird das erste Erscheinen der ersten Generation an den einzelnen Fruchtarten angeführt. Das Geschlechterverhältnis war 1 : 1. Die erhaltenen Resultate werden zu den entsprechenden Faktoren in Beziehung gebracht.Der Autor dankt dem Wissenschaftlichen Direktor vielmals für alle Unterstützung während der Arbeit. Besonderer Dank gebührt meinen Kollegen Mr.A. Arafat, Mr.J. Qasim und MissC. Sudah für ihre wertvolle Hilfe. Die Direktoren und Superintendenten der Landwirtschaftlichen Stationen in Tulkarm, Fara'a, Arroub und Jubeiha gewährten jede Hilfe. 相似文献

Polypropylene (PP) fabrics were activated by an atmospheric pressure, dielectric barrier discharge to optimize the effects
of some discharge parameters on the dyeability of PP fabrics. Air and argon plasmas were used to modify the surfaces of the
fabrics, and the effects on dyeability were investigated when the treated fabrics were dyed by leuco and pigment forms of
vat dyestuffs. Surface properties of plasma-treated samples were characterized by Fourier transform infrared spectroscopy
(FTIR-ATR), X-ray photoelectron spectroscopy (XPS), and scanning electron microscopy (SEM). Vat-dyed samples showed a significant
increase in color strength when PP fabrics were pretreated with atmospheric pressure plasmas of either argon or air. 相似文献

Effects of kefir on coccidial oocysts excretion and performance of dairy goat kids following weaning
Daş G Ataşoğlu C Akbağ HI Tölü C Yurtman IY Savaş T 《Tropical animal health and production》2012,44(5):1049-1055
The aim of this study was to investigate effects of kefir, a traditional source of probiotic, on coccidial oocysts excretion
and on the performance of dairy goat kids following weaning. Twin kids were randomly allocated to one of two groups at weaning.
Kids of the first group received 20 ml of kefir daily for 6 weeks (KEF), while kids in the control group were given a placebo
(CON). Individual faecal samples were regularly (n = 18 per kid) taken to quantify the number of coccidial oocysts per gram of faeces (OpG). There were no differences between
the groups in terms of body weight development (P > 0.05) and feed consumption. Kids of both groups were not able to consume enough feed to meet their nutrient requirements
during the first 3 weeks following weaning. KEF had a lower frequency of OpG positive samples than CON (P = 0.043). Kefir did not affect the maximum oocyst excretion and age of the kids at the highest oocyst excretion (P > 0.05). KEF shed numerically 35% lower coccidial oocysts than the controls, which corresponded to a statistical tendency
(P = 0.074) in lowering Log-OpG in comparison to CON. While KEF had a lower frequency of OpG positive samples and tended to
shed lower OPG by around one-third, the frequency of diarrhea, level of highest oocyst excretion, and performance of the kids
remained unaffected. Therefore, it is concluded that overall effects of kefir do not have a significant impact on sub-clinical
infection and performance in weaned kids under relatively high-hygienic farming conditions. 相似文献

In this study, the pathogen and parasite spectra of Turkish populations of the great spruce bark beetle Dendroctonus micans (Kugelann) (Coleoptera: Curculionidae, Scolytinae) are analysed. In addition to the previously studied infective green alga
Helicosporidium, three more pathogens and parasites, i.e. the yeast Metschnikowia sp., the neogregarine Mattesia sp. and a nematode, were recorded here for the first time. The pathogens and parasites occur in different quantities and
combinations in outbreaks of the beetle at five Turkish localities. 相似文献

In the present study, we used 39 plant samples representing six Carthamus taxa collected from different regions of Turkey: 11 of C. dentatus, 5 of C. glaucus, 18 of C. lanatus, 3 of C. persicus, 1 of C. tenuis subsp. tenuis and 1 of C. tenuis subsp. gracillimus. On these samples, we screened nine ISSR markers for polymorphic products. We generated 151 polymorphic bands. In a dendrogram based on these ISSR bands, the first branch was C. tenuis subsp. gracillimus, then C. persicus formed the second group. The rest of the taxa were grouped in two clusters: the first included C. lanatus, C. tenuis subsp. tenuis and C. glaucus, and the second included C. dentatus. Within the first cluster, C. tenuis subsp. tenuis and C. glaucus grouped together and then united to C. lanatus. Representatives of the same taxa consistently clustered together. Also within species, the groupings were generally concordant with their geographical distributions. 相似文献

The dyeing properties of the polypropylene (PP) fabrics using cationic dyestuffs were investigated after surrounded air atmospheric cold-plasma treatment. Surrounded air plasma (SAP) was used to modify fabric surface and to optimize the effects of some discharge parameters on dyeability. Surface morphology and physical-chemical properties of plasma treated fibers were also characterized by Fourier transform infrared attenuated total reflection spectroscopy, X-ray photoelectron spectroscopy, and scanning electron microscopy. Activated surfaces by SAP were grafted with different compounds: 6-aminohexanoic acid, acrylic acid, and hexamethyldisiloxane. Dyeing the plasma-induced grafted PP fabric with basic dye was quite satisfactory when high color strength and good fasteness were considered. 相似文献

A new Microsporidium sp. infects Rhizophagus grandis Gyllenhall, a beetle which preys on the bark beetle Dendroctonus micans Kugellan in Turkey. Mature spores are single, uninucleate, oval in shape (3.75 +/- 0.27 microm in length by 2.47 +/- 0.13 microm in width), with a subapically fixed polar filament. The polar filament is anisofilar, coiled in 7-8 normal and 3-4 reduced coils. Other characteristic features of the microsporidium are the four/five nuclear divisions to form 16/32 (commonly 16) spores, subpersistent sporophorous vesicles (pansporoblasts) remaining till formation of the endospore, and the vesicles dissolved with free mature spores. The polaroplast is divided into three zones: an amorphous zone, dense layers, and a lamellartubular area extending to the central part of the spore. 相似文献

Vegetative compatibility groups in Colletotrichum coccodes from Turkey and their aggressiveness to potato 
下载免费PDF全文
下载免费PDF全文 Black dot, caused by Colletotrichum coccodes, is a common disease of potato in Turkey, affecting tuber quality and yield. The objectives of the current study were to characterize vegetative compatibility groups (VCGs) of C. coccodes isolates from three regions in Turkey, and to assess the correlation between VCGs and aggressiveness of isolates on potato. A total of 147 C. coccodes isolates were recovered from plants showing typical black dot symptoms on stolons, roots and stems. The frequency of nitrate non‐utilizing (nit) nit1/nit3 and NitM phenotypes were 79% and 21%, respectively. Complementation between nit mutants of the isolates and eight European/Israeli EU/I‐VCG tester isolates was used to characterize the VCGs. Amongst the tested isolates, 33.3% were assigned to EU/I‐VCG6, 21.8% to EU/I‐VCG8, 15.7% to EU/I‐VCG4. EU/I‐VCG1, EU/I‐VCG3, EU/I‐VCG5 and EU/I‐VCG7 were classified at 1.4%, 3.4%, 4.8% and 5.4%, frequency, respectively. No isolate was assigned to EU/I‐VCG2 group, while 21 isolates (14.3%) were not assigned to any of the EU/I‐VCGs. The pathogenicity tests indicated significant differences in aggressiveness of the isolates with respect to sclerotia density on potato tissues. The highest densities of sclerotia on roots and crown were obtained with EU/I‐VCG6 isolates and the lowest with EU/I‐VCG1, EU/I‐VCG3 and EU/I‐VCG5 isolates. The results demonstrate that there is significant VCG diversity among C. coccodes isolates from potato plants in Turkey. 相似文献
