Öğe A New Pest Cydalima perspectalis (Walker, 1859) (Lepidoptera: Crambidae) For Düzce(Düzce Üniversitesi, 2016) Öztürk, Nuray; Akbulut, Süleyman; Yüksel, BeşirCydalima perspectalis (Walker) (Lepidoptera: Crambidae) is a harmful species on Buxus spp. that is used as outdoor ornamental plants in parks and gardens. C. perspectalis is originated from the East Asia and it is an invasive species for Turkey. This species has been detected in Germany and Netherland for the first time in Europe in 2007. C. perspectalis were found on the leaves of Buxus sempervirens ve B. sempervirens cv ‘aureavariegata’ species in Istanbul in 2007. Since the spring months 2015, insect damage has been observed on B. sempervirens in the central province of Duzce.Because of pest species at pupal stage, pupa samples and damaged parts of plants has been brought to the Duzce University Faculty of Forestry, Laboratory of Forest Entomology and Protection. Collected pupa samples were placed in an insect rearing cage for adult emergence under constant conditions. Photos of damaged plant parts were taken. Only one pupae out of four was emerged as an adult and identification process was carried out.In addition, the type of damages on plant parts were compared with data in the literature. In conclusion, this insect species was identified as Cydalima perspectalis. This is the first report of C. perspectalis from Duzce. It has a potential to be an important pest on B. sempervirens used in city parks and gardens in Duzce. To control the spread of the pest, periodic monitoring of the population and preventive measures should be carried out.Öğe Antennal responses of Cydia pomonella (L.) exposed to surfaces treated with methoxyfenozide(Wiley, 2013) Barrett, B.A.; Keesey, I.W.; Akbulut, Süleyman; Stamps, W. TerrellElectroantennogram (EAG) measurements were recorded from the antennae of male and female codling moth, Cydia pomonella L., to determine whether adult moths exposed to surfaces treated with the ecdysteroid agonist methoxyfenozide experience a decline in their antennal reception and thus olfactory sensitivity. Such a phenomenon would offer a possible mechanism for the previously reported decreased responsiveness from moths treated with methoxyfenozide to pheromone-and plant volatile-based monitoring lures. Mean EAG data revealed that the antennae from methoxyfenozide-treated male moths appear to be just as sensitive to various doses of synthetic codlemone as the antennae from the control and surfactant-treated moths, but they appeared to be less sensitive to the pheromone component 12OH (collected from female effluvia) than the control male antennae. Mean male EAG responses to the pheromone components E8, E10-12Al and codlemone collected from methoxyfenozide-treated females were significantly less than the responses towards those two pheromone components collected from the control and surfactant-treated females. Female moth exposure to methoxyfenozide did not negatively impact the sensitivity of female antennae to the plant volatile pear ester, but it did towards the apple volatile butyl hexanoate. Data from this study show that adult C. pomonella exposure to methoxyfenozide-treated surfaces does appear to negatively impact, in a minor way, the (i) olfactory sensitivity (or detection) of male antennae towards some components of the female sex pheromone, (ii) the female antennal sensitivity towards a key apple volatile and (iii) the attractiveness of female pheromone effluvia.Öğe Arbutus unedo L. VE Phillyrea latifolia L. İÇİN AKTİF YANICI MADDE VE TOPRAK ÜSTÜ TOPLAM BİYOKÜTLE MİKTARININ TAHMİN EDİLMESİ(2022) Öztürk, Nuray; Baysal, İsmail; Akbulut, SüleymanBu çalışmada, kocayemiş (Arbutus unedo L.) ve akçakesme (Phillyrea latifolia L.) türlerinin bireylerinde aktif yanıcı madde ve toplam biyokütle miktarını belirlemeye yönelik arazi ve laboratuvar çalışmaları gerçekleştirilmiştir.

Only pine trees (Pinus nigra, P. pinaster and P. sylvestris) yielded Bursaphelenchus specimens. Nematodes were identified using several morphological diagnostic characters of the genus (male spicule structure, number of lateral incisures, number and distribution of the male papillae, presence of female vulval flap), and confirmed by using RFLP analysis of the internal transcriber spacer (ITS) regions of ribosomal DNA. Three different species were identified from several sampled areas, namely B. mucronatus, B. pinophilus and B. sexdentati, representing a first report of the last two species for Turkey. The association of B. pinophilus with black pine (P. nigra) is herein reported for the first time.Öğe Cerambycids as plant disease vectors with special reference to pine wilt(CRC Press, 2017) Akbulut, Süleyman; Togashi, Katsumi; Linit, Marc J.The genus Monochamus Dejean belongs to the subfamily Lamiinae of the family Cerambycidae, which is one of the largest and most important among wood-boring families (Linsley 1961). Species from this genus are called “pine sawyers” because the larvae make a loud noise as they tunnel within the wood of host trees. They feed on conifers and broad-leaved trees. In Japan, some species feed on both (Kojima and Nakamura 2011). Many species attack dying, newly dead, or freshly cut trees of the genera Pinus L., Picea Mill., and Abies Mill., and are considered secondary pests. © 2017 by Taylor & Francis Group, LLC.Öğe Comparison of pathogenic potential of Bursaphelenchus species on conifer seedlings between greenhouse and outdoor conditions(Springer, 2015) Akbulut, Süleyman; Yüksel, Beşir; Serin, Metin; Erdem, MahirBursaphelenchus xylophilus is a serious threat to the European conifer forests. In Turkey, four Bursaphelenchus species (B. mucronatus, B. sexdentati, B. anamurius and B. vallesianus) were isolated from wilted pine trees. To determine the effects of Bursaphelenchus species on the wilting of pine trees, a pathogenicity study was conducted comparing greenhouse and outdoor conditions. Three-year-old seedlings of Pinus nigra, P. sylvestris and P. pinaster were used for inoculation tests. Approximately 1000 (+/- 100) nematodes of all life stages in 0.5 ml distilled water were inoculated into each seedling. The first wilting symptoms were observed in the fifth week. Mortalities occurred between the 5th and 13th weeks of the study. B. mucronatus was the most pathogenic nematode species. The most susceptible seedling species was P. pinaster, and P. nigra was the most resistant species. The mean number of wilted seedlings differed significantly among nematode species and seedling species but not between greenhouse and outdoor conditions.Öğe Comparison of the reproductive potential of Monochamus galloprovincialis on two pine species under laboratory conditions(Springer, 2009) Akbulut, SüleymanMonochamus galloprovincialis Olivier (Coleoptera: Cerambycidae) is one of the vectors of the pinewood nematode Bursaphelenchus xylophilus (Steiner and Buhrer) Nickle (Nematoda: Parasitaphelenchidae), the causal agent of pine wilt in susceptible pine trees. It is therefore important to study both the biological and ecological characteristics of the beetle. In this study reproductive potentials of female beetles reared on two pine species were investigated under laboratory conditions and compared using fertility tables constructed for beetles reared on each tree species. Beetle population parameters were compared between tree species. The intrinsic rate of increase and associated population parameters of beetles reared on Pinus sylvestris L. were consistently higher than those reared on P. nigra Arnold. This result suggests that P. sylvestris has a significantly greater positive effect on the reproductive potential of M. galloprovincialis populations than does P. nigra.Öğe Description of Bursaphelenchus anamurius sp n. (Nematoda : Parasitaphelenchidae) from Pinus brutia in Turkey(Brill Academic Publishers, 2007) Akbulut, Süleyman; Braasch, Helen; Baysal, İsmail; Brandstetter, Martin; Burgermeister, WolfgangBursaphelenchus anamurius sp. n. isolated from wilted Turkish pine (Pinus brutia Ten.) wood is described. The new species shares several characters with the hofmanni-group sensu Brasch (2001). It is characterised by a body length of 633 (540-749) mu m and 744 (638-867) mu m for males and females, respectively, stout body (a = 29 in male and 27 in female), stylet 14 mu m long in both males and females, lateral field with three lines, length of postuterine branch one-third to one-half of the vulva to anus distance, conoid female tail (c' = 3.4) with a finely rounded or pointed terminus, very delicate and relatively straight spicules 10 (9-11) mu m long with compact capitulum, broad, not distinctly offset condylus and strong rostrum with a more or less rounded tip lacking a cucullus, shovel-shaped bursa and the presence of seven caudal papillae. Bursaphelenchus anamurius sp. n. differs from other species of the hofmanni-group mainly by having smaller, unusually shaped spicules, shorter condylus and no cucullus. The new species can be differentiated from other Bursaphelenchus species morphologically and by means of ITS-RFLP patterns, particularly by digestion of the PCR product with RsaI, HaeIII, MspI, HinfI and AluI.Öğe Determination of pathogenicity of Bursaphelenchus species on different pine species under natural conditions in Duzce(Springer, 2019) Öztürk, Nuray; Akbulut, Süleyman; Baysal, İsmailThe pinewood nematode, Bursaphelenchus xylophilus is a pathogen of conifer forest trees. This pest is characterized by the sudden death of infected pine trees. In this study, pathogenicity tests of six native Bursaphelenchus species (B. mucronatus, B. sexdentati, B. anamurius, B. vallesianus, B. andrassyi and B. hellenicus) on three pine species (Pinus pinaster, P. nigra and P. sylvestris) using two inoculum doses under natural conditions were conducted. For each treatment, 8 trees of each species were inoculated. For each tree species 8 trees were used as control groups. Inoculated trees were monitored for a year after inoculation. Monthly oleoresin flow measurements were carried out and external symptoms (foliage coloration) observed. Nematode inoculated trees did not die at the end of the study. The amount of oleoresin flow differed significantly among tree species. Inoculated Bursaphelenchus species did not cause any significant difference in the oleoresin flow between inoculated and uninoculated trees. We concluded that Bursaphelenchus species used in this study were not pathogenic to pine trees growing under natural forest stand conditions.Öğe Dreyfusia nordmannianae in Northern and Central Europe: Potential for biological control and comments on its taxonomy(2013) Ravn, Hans Peter; Havill, Nathan P.; Akbulut, Süleyman; Foottit, Robert G.; Serin, Metin; Erdem, Mahir; Kenis, MarcThe silver fir woolly adelgid, Dreyfusia nordmannianae, is the most severe pest occurring on Abies nordmanniana in Central and Northern Europe. The adelgid is particularly damaging to trees in Christmas tree plantations. Dreyfusia nordmannianae is native to the Caucasus region and alien to Europe, where its natural enemy complex is less diverse compared to its area of origin. Mitochondrial and nuclear DNA sequence data from the samples of D. nordmannianae collected in its native range and Europe and from the samples of Dreyfusia piceae and Dreyfusia prelli collected in Europe and North America were examined for phylogenetic structure. There was no evidence of differentiation, suggesting that these Dreyfusia species have recently diverged or require taxonomic revision. All existing published and unpublished reports on natural enemies of D. nordmannianae in its place of origin were reviewed, with the purpose of selecting agents for classical biological control in Europe. The literature review suggested that the most promising agent was the Chamaemyiidae fly, Leucopis hennigrata. A new survey in D. nordmannianae's area of origin - Turkey, Georgia and Russia - showed that L. hennigrata was present in all localities. It was particularly abundant in Turkey, where its impact on populations of D. nordmannianae appears to be high. Its use as a biological control agent is discussed, as well as other biological control strategies. © 2012 Blackwell Verlag, GmbH.Öğe Düzce İlinde Faaliyet Gösteren Parke Endüstrisinin İncelenmesi(Düzce Üniversitesi, 2010) Korkut, Derya Sevim; Akbulut, SüleymanBu çalısmada parke isletmelerinin mevcut durumu, karsılastıkları sorunlar ve gelecekteki hedefleriarastırılmıstır.

This problem has increased the scientific interest in Bursaphelenchus species both in the world and in Turkey. Previously, six Bursaphelenchus species were isolated from wilted pine trees in Turkey. The main goal of this study was to investigate the effects of nematode inoculation on the total carbohydrate concentrations of tree species. Native six Bursaphelenchus species were inoculated on three pine species (Pinus pinaster, P. nigra, and P. sylvestris) under natural stand conditions. Two different doses of nematodes (2000 and 20,000) were used for inoculation. For each treatment, three trees of each species were inoculated. The total carbohydrate concentrations were differed significantly among tree species, nematode species and between nematode doses. The total carbohydrate concentration values were higher in P. pinaster than both P. nigra and P. sylvestris. These results may suggest that pine species responded to nematode inoculation by changing the amount of TCC.Öğe Effect of log seasonality on reproductive potential of Monochamus galloprovincialis reared in Scots pine logs under laboratory conditions(Springer, 2008) Akbulut, Süleyman; Baysal, İsmail; Keten, Akif; Yüksel, BeşirInsect reproduction may be affected by a number of factors including seasonal changes in larval or adult nutrition. The effect of season on the reproductive potential of Monochamus galloprovincialis (Olivier) females reared in Pinus sylvestris L. (Scots pine) logs was investigated by constructing fertility tables for each log that differed only in the season they were cut. Population parameters were compared among three seasonal cohorts. The intrinsic rate of increase and most of the associated population parameters of beetles that emerged from logs cut during spring were higher than for beetles emerged from summer and autumn logs. Slight differences were found between summer and autumn cohorts. We suggest that seasonal differences in the nutritional quality of logs caused differences in M. galloprovincialis survival and reproductive potential.Öğe The effect of log seasonality on the reproductive potential of Monochamus galloprovincialis Olivier (Coleoptera : Cerambycidae) reared in black pine logs under laboratory conditions(Tubitak Scientific & Technical Research Council Turkey, 2007) Akbulut, Süleyman; Keten, Akif; Baysal, İsmail; Yüksel, BeşirMonochamus galloprovincialis (Olivier) is the vector of the pinewood nematode, Bursaphelenchus xylophilus (Steiner and Buhrer) Nickle, in Europe and Asia. Reproduction is probably the most important event in the life history of insects and may be affected by a number of factors, such as seasonal changes in larval or adult nutrition. In this study the effect of season on the reproductive potential of M. galloprovincialis females reared in black pine logs was investigated by constructing fertility tables for each of 43 pine logs that differed only in the season that they were cut. Population parameters were compared among 3 seasonal cohorts. The intrinsic rate of increase and related population parameters of the beetles that emerged from autumn logs were mostly higher than for beetles that emerged from spring and summer logs. These results suggest that seasonal differences in the nutritional quality of the logs (for immature development) and pine twigs (for adult feeding) may have caused the observed differences in M. galloprovincialis survival and reproduction.Öğe Effects of different ecological and silvicultural factors on beetle catches in the Turkish fir (Abies bornmulleriana Mattf.) ecosystems(Springer Heidelberg, 2007) Yıldız, Oktay; Eşen, Derya; Akbulut, SüleymanTo 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.Öğe First record of Aphelenchoides stammeri ( Nematoda: Aphelenchoid dae) from Turkey(Soc Nematologists, 2019) Dayı, Mehmet; Uludamar, Ece B. Kasapoğlu; Akbulut, Süleyman; Elekcioğlu, İbrahim HalilIn previous surveys for the investigation of Bursaphelenchus xylophilus in Turkey, several Bursaphelenchus species, except B. xylophilus, were detected. To determine the insect vectors of these previously reported Bursaphelenchus species, trap trees of each pine species (Pinus brutia and P. nigra) were cut and kept in the field from April to September in 2011. Aphelenchoides stammeri was isolated from wood chip samples of P. nigra from Isparta (Sutguler). A. stammeri was first identified by using morphological features and allometric criteria of females and males. In addition, molecular analysis using sequences of 18S and 28S ribosomal (rRNA) genes of A. stammeri was performed. This is the first report of A. stammeri from Turkey.Öğe First record of Bursaphelenchus vallesianus Braasch, Schonfeld, Polomski, and Burgermeister in Turkey(Tubitak Scientific & Technical Research Council Turkey, 2008) Akbulut, Süleyman; Elekcioğlu, İbrahim Halil; Keten, AkifBursaphelenchus vallesianus isolated from a dead Scots pine, Pinus sylvestris, in the village of Bahcecik northeastern Turkey in an area managed by the Trabzon Regional Forestry Directorate is described and illustrated.
