In this paper, three new Phyllocoptini eriophyoid mite species from Yunnan Province, China are described and illustrated: Proiectus rodgeseta sp. nov. on Pinus armandii Franch. (Pinaceae), Proiectus granularpro sp. nov. on Pinus tabuliformis Carr. (Pinaceae) and Phyllocoptrutajuniperiana sp. nov. on Juniperus chinensis Linn. (Cupressaceae). All are vagrants causing no apparent damage to their h...
Aprostocetus pinus sp. nov. (Chalcidoidea: Eulophidae) is newly described as a leaf bud and microstrobilus pest of Pinus massoniana (Pinales: Pinaceae), an important afforestation species in southeast China. Both sexes of the parasitoid are described and illustrated.
Fossil records indicate that the genus Pinus L. split into two subgenera by the Late Cretaceous, although subgenus Strobus (D. Don) Lemmon is less well documented than subgenus Pinus L., especially in eastern Asia. In this paper, Pinus maomingensis sp. nov. is established based on a compressed seed cone from the upper Eocene of the Maoming Basin of southern China. This species is attributed to ...
Fungal endophytes are microfungi that live in plants without causing apparent symptoms of infection. This study was conducted to identify endophytic fungi isolated from leaves of coniferous trees in Bohyeon Mountain of Korea. We collected leaves of two species of coniferous trees, Pinus densiflora and Pinus koraiensis, from 11 sites in the study area. A total 58 isolates were obtained and ident...
Three new species of the genus Stigmaeus Koch, 1836 (Acari: Stigmaeidae) are described from various habitats in Crimea: Stigmaeus kuznetsovi sp. nov. from nests of Microtus socialis (Rodentia: Cricetidae); S. mitrofanovi sp. nov. from galleries of Pityogenes bistridentatus (Coleoptera: Curculionidae) under the bark of Pinus pallasiana, and S. silvestris sp. nov. from rotten log of Pinus pallasi...
Wood borer species of the families Euplatypodidae and Scolytidae were observed attacking trees of Pinus sp. in the Municipality of Ribas do Rio Pardo, state of Mato Grosso do Sul, Brazil, in March 2000. This plantation had been previously burned in an accidental fire in January 2000, causing the trees to become partially or totally unhealthy, rendering them more susceptible to attack of these p...
مقاله حاضر شامل سه طرح تحقیقاتی در سه منطقه ارتفاعی در استان گیلان است. در منطقه ارتفاعی پایینبند به ارتفاع 450 متر در جنگلهای اسالم واقع در طرح سیاهبیل شماره یک، 13 گونه و پروونانس مورد آزمایش قرار گرفته است. در منطقه میانبند واقع در طرح ناو اسالم به ارتفاع 1050 متر، 15 گونه و پروونانس و در منطقه بالابند به ارتفاع 1750 متر واقع در طرح ناو اسالم، 9 گونه و پروونانس کشت گردید. در هر منطقه طرح...
Commercially available enzymes do not contain all the necessary softwood-specific accessory enzymes to obtain high saccharification efficiency. In this work, six saprophytic fungi obtained from Pinus radiata plantation site were screened for the putative softwood-specific accessory enzyme, β-mannanase. A Penicillium sp. was found to produce β-mannanase in both solid (31.6 units/g of dry biomass...
results the results of the study, using the two methods, showed that all methanol extracts of leaves and fruits of the six species possessed antioxidant activity. the antioxidant activity of the samples was compared with the antioxidant activities of butylatedhydroxytoluene (bht), as a synthetic antioxidant and α-tocopherol as a natural antioxidant. methanol extractions of pinus spp. leaves and...
Pinus trifolia Miki 1939 (Pinaceae) was originally proposed based on seed cones from the upper Miocene of Aichi and Gifu Prefectures, central Japan. However, before the publication of P. trifolia, a different name (Pinus fujiii (Yasui) Miki) was given to a female cone with the same morphology. On the other hand, P. fujiii auct. non (Yasui) Miki has been used for seed cones with different morpho...
