The occurrence of Cerambycidae (Lamiinae) was evaluated in trunk and branch samples of cardeiro (Scleronema micranthum), a forest species from the Central Amazon. Samples were exposed to biodegradation for 24 months on the forest soil, during which adults and larvae were collected and their attack was evaluated. From a total of 643 cerambycids collected, 606 were immatures and 37 were adults. T...

Five new spirobifuranocoumarins, dahuribirins A-E (1-5) and two new bifuranocoumarins, dahuribirins F and G (6 and 7) were isolated from Japanese Bai Zhi (the root of Angelica dahurica Benth. et Hook. var. dahurica Benth. et Hook.) and their structures were established by chemical and spectral means.

Two acyl phloroglucinol compounds namely; Sideroxylonal B (1) and Macrocarpal A (2) were isolated from the Sideroxylonal-Rich Extract (SRE) of the juvenile leaves of Eucalyptus cinerea; F. Muell. ex Benth cultivated in Egypt. Identification of the isolated compounds was established on the basis of physico-chemical properties and spectral analysis (1D & 2D NMR). The two compounds were isolated f...

Various viewpoints were proposed to explain the causes of recent years’ severe drought occurred in Yunnan and Guizhou, China. In general there are two parties of viewpoints, the Eucalyptus cause and climate change cause. I think Yunnan-Guizhou drought has been mainly caused by abnormal climate change. Eucalyptus was not significant in the formation of Yunnan-Guizhou drought. However, the forest...

Drying is an important process in the generation of wood products, as it increases quality final products; however, influenced by various anatomical characteristics. The aim this study was to evaluate influence anatomy on drying Parapiptadenia rigida (Benth.) Brenan, Peltophorum dubium (Spreng.) Taub., Eucalyptus grandis W. Hill × urophylla S.T. Blake (hybrid), and Schizolobium parahyba (Vell.)...

the leaves of four cultivated eucalyptus species, eucalyptus microtheca var. microtheca f. muell., eucalyptus spathulata, eucalyptus largiflorens and eucalyptus torquata were collected in spring from kashan and isfahan provinces (central region of iran). after drying the plant materials in shade, their essential oils were obtained by hydro-distillation. the oils were analyzed by capillary gas c...

Summary At the time of description, morphology Ptychaphelenchus eucalypticola Hodda, 2009 indicated it could be assigned to either Aphelenchoididae Skarbilovich, 1947 (Paramonov, 1953) or Parasitaphelenchidae Ruehm, 1956 (Siddiqi, 1980) within Aphelenchoidoidea 1980). Although P. was, tentatively, and remains Aphelenchoididae, its relationships with other aphelenchoids have not been reassessed,...

A set of over 8000 Diversity Arrays Technology (DArT) markers was tested for its utility in high-resolution population and phylogenetic studies across a range of Eucalyptus taxa. Small-scale population studies of Eucalyptus camaldulensis, Eucalyptus cladocalyx, Eucalyptus globulus, Eucalyptus grandis, Eucalyptus nitens, Eucalyptus pilularis and Eucalyptus urophylla demonstrated the potential of...

Eucalyptus is well reputed for its use as medicinal plant around the globe. The present study was planned to evaluate chemical composition, antimicrobial and antioxidant activity of the essential oils (EOs) extracted from seven Eucalyptus species frequently found in South East Asia (Pakistan). EOs from Eucalyptus citriodora, Eucalyptus melanophloia, Eucalyptus crebra, Eucalyptus tereticornis, E...
