Wood samples (poplar, Scots pine, beech, and lime) were impregnated with melted honeybee wax under vacuum. The wax-impregnated samples were exposed to the wood-decay fungi Trametes versicolor and Neolentinus lepideus for 8 weeks. The larvicidal effect of the beeswax was tested against European old house borer (Hylotrupes bajulus L.). Water uptake, color measurements, and surface hardness were also tested. According to the obtained findings, a 34.6% mass loss was seen in the poplar control wood, and only 3.9% mass loss was found in the 100% beeswax-impregnated samples. The results showed that H. bajulus larvae could digest honeybee wax with wood when beeswax surface treatment was applied. Additionally, an average of 30% larvae mortality rate was achieved on beeswax-treated wood surfaces, compared to a 2.5% rate on the con...

Hazelnut branch waste was used for the first time in oyster mushroom cultivation. In the study, mushrooms were grown by preparing composts from 100 to 50% mixtures of each waste type. Yield, biological activity, spawn run time, total harvesting time and mushroom quality characteristics were determined from harvested mushroom caps. In addition, chemical analysis of lignocellulosic materials (extractive contents, holocellulose, α-cellulose, lignin and ash contents) were carried out as a result of mushroom production and their changes according to their initial amounts were examined. In addition, the changes in the structure of waste lignocellulosic materials were characterized by FTIR analysis. As a result of the study, 172 g/kg yield was found in wheat straw used as a control sample, ...

Çalışmada, Düzce ilinde kereste artıklarından ortaya çıkan meşe ve kayın talaşı ile fındık kabukları mantar yetiştirme ortamı olarak değerlendirilmiştir. Bu kapsamda, kullanılan fındık kabukları Wiley değirmeninde öğütülmüştür. Kayın ve meşe talaşları ise kereste işleyen bir fabrikadan hazır olarak temin edilmiştir. Odun talaşları ve fındık kabukları belli oranlarda karıştırılarak kompostlar hazırlanmıştır. Hazırlanan kompostlar, 121 °C ve 1.1 atm'de steril hale getirilmiştir. Şitaki mantar miseli aşılanan kompostlar 26 °C sıcaklık ve %80 bağıl nem ortamında inkübasyon süresini tamamlamış sonrasında ise 5°C'de bekletilip promordium oluşması için tekrar yetiştirme odasına alınmıştır. Özellikle %100 fındık kabuğu ile üretilen mantarların, meşe ve kayın talaşına göre verim bakımından daha düşük değerler verdiği tespit edilmiştir. Ancak fındık kabuğunun diğer iki materyal ile 1:1 oranında karışımlarından elde edilen verimlilik ve biyolojik etkinlik değerleri yalnızca meşe ve kayın talaşından üretilen mantarlarınki ile yaklaşık aynı oran/değerlerdedir. En yüksek verimlilik ve biyolojik etkinlik değerleri meşe talaşı kompostundan elde edilmiştir. Kimyasal içerik sonuçlarına göre, fındık kabuğu ve karışımları toplam azot ve protein bakımından en yüksek değerlere sahiptir. Toplam enerji, karbonhidrat ve yağ oranları bakımından ise kompost karışımları arasında önemli sayılabilecek farklılık tespit edilmemiştir.

This study aimed to use methanolic propolis extract (MPE) as a treatment material as an antifungal agent for wood preservation. Scots pine and paulownia woods were exposed to Trametes versicolor and Neolentinus lepideus fungi for 12 weeks, and untreated woods were used as the controls. Compared with the control, paulownia wood exposed to N. lepideus had a 47.2% mean mass loss, while the treated wood with 7% MPE had an 11.6% mean mass loss. In addition, a 27.2% mass loss occurred with the control for Scots pine when exposed to N. lepideus, and a 2.5% mass loss occurred with the 7% propolis-treated specimens. Total phenolic content and the phenolic profile of the raw propolis samples were also analyzed. Scanning electron microscopy images showed that the propolis extracts still remained in the wood cells without being degraded after the fungal destruction and the prop...

Solutions were prepared by dissolving waste tar in ethanol:toluene (1v:1v) in concentrations of 5%, 10%, 15% and 20% and treated under vacuum and pressure. In addition, surface coating (SC) was applied by spreading 96% waste tar on the wood surfaces after treatment. Deep-treated and surface-coated (DT+SC) wood samples were exposed to the wood-decay fungi (<em>Corillous versicolor</em> L. and <em>Neolentinus lepideus</em> Fr.) and wood destroying house borer (<em>Hylotrupes bajulus </em>L.) larvaes. Total phenolic content, water uptake, water-repellent efficiency and surface contact angle were tested. The highest mean weight loss (45.23%) was found in the beech wood control samples exposed to <em...

In this context either single or five geometrical surfaces of Scots pine and beech wood specimens were carbonized and exposed to Coniophora puteana (brown rot) and Pleurotus ostreatus (white rot) decay fungi for 12 weeks. According to the results single or five surface carbonized Scots pine specimen showed reduced weight loses when compared to un-carbonized controls. Beech wood specimens, on the other hand, resulted significantly low weight losses only for five surface carbonized specimens. A statically significant difference was found between the control samples of both wood species. In terms of weight loss, no statistically significant difference was found between beech control samples and samples exposed to white rot fungi. These results showed that the combustion process provides efficacy against brown rot in both wood species and white rot only in Scots pine.

The study covered two years, 2015 and 2016, in 21 log depots in seven provinces (Duzce, Bolu, Zonguldak, Bartin, Karabuk, Kastamonu and Sinop). The study area was divided into three sub regions and each sub region was analyzed for insect species, their prevalence and intensities. Overall, four orders, 22 families, 74 genera and 57 species were described in log depots of the study area. Sub region 1 (Düzce-Bolu) showed the highest diversity in terms of insect species and sub region 2 (Zonguldak-Bartin) had the lowest diversity. Dorcus parallelipipedus Linnaeus, 1758 (Coleoptera: Lucanidae) and Rhagium inquisitor Linnaeus, 1758 (Coleoptera: Cerambycidae) were found in all provinces studied. Based on wood species analysis, Scots pine wood had the highest diversity in insect species, followed by fi r, oak and beech. The study also described some important wood-destroying insect species from the...

Scotch pine (Pinus sylvestris), oak (Quercus petreae) and beech (Fagus orientalis) wood species were heat treated at 190°C for 2 h, 212°C for 1 h and 2 h by the ThermoWood® method. Untreated and heat-treated specimens were exposed to white-rot fungus (Pleurotus ostreatus) and brown-rot fungus (Coniophora puteana) for 12 weeks according to procedures defined in JIS K 1571 standard. After weight losses of all specimens were calculated. According to the results, least weight loss was determined on heat treated at 212°C for 2 h. Heat treatment can be used effectively against fungal attack for Scotch pine, oak and beech wood species.

The Bevan damage classification (BDC) system, developed in 1987, was utilized to determine damage severity in log depots in 21 locations throughout seven provinces in Turkey. Pheromone traps were placed in those locations at the beginning of April in 2015 and 2016. Furthermore some stored wood within the log depots were checked and split into small pieces to collect insects that damage wood. The BDC system was used for the first time to measure the severity of insect damage in log depots. Twenty-eight families, 104 genera and 123 species were identified in this study. Based on the BDC system, the highest damage was found from the Cerambycidae and Buprestidae families.Arhopalus rusticuswas determined as the insect responsible for the highest amount of damage with 8.8% severity rating in the pheromone-trapped insects group. When the stored wood material was considered,Hylo...
