Studies were carried out for 90days on the degradation of wood wastes of four economically important Nigerian trees; Terminalia superba, Mansonia altissima, Holoptelia grandis and Milicia excelsa by white rot fungus, Pleurotus tuber-regium a Nigerian edible mushroom. The pH of the wastes dropped to 4.0/4.2, 90days after incubation. On the contrary, amino nitrogen content of the wastes increased...

Invasive plants often experience rapid changes in biological interactions by escaping from their original herbivores at their new habitats, and sometimes re-associating with those herbivores afterwards. However, little is known about whether the temporal changes in herbivorous impact work as a selective agent for defensive traits of invaded plants. Solidago altissima (goldenrod) is a North Amer...

The spotted lanternfly, Lycorma delicatula (White) (Hemiptera: Fulgoridae), was first detected in the United States Berks County, Pennsylvania, 2014. Native to China, this phloem-feeding planthopper threatens agricultural, ornamental, nursery, and timber industries its invaded range through quarantine restrictions on shipments, as well impacts plants themselves. long-term of L. feeding tree spe...

The article contains new information about the locations of rare and spreading species flowering plants in Western Siberia Southern Ural (Kurgan Region, Chelyabinsk Tomsk Republic Altai). Among them, four (Bidens frondosa L., Lappula intermedia (Ledeb.) Popov, Melica altissima Verbascum lychnitis L.) are reported as for three (Aquilegia vulgaris Dianthus barbatus Lepidium sativumL.) Altai, two ...

Host-associated mating is crucial in maintaining the partial reproductive isolation between the host races of Eurosta solidaginis (Diptera: Tephritidae), a fly that forms galls on Solidago altissima and S. gigantea. (We refer to flies reared from S. gigantea as gigantea flies and those reared from S. altissima as altissima flies.) We measured the host preference of males and females of both hos...

The distribution of 14 iridoid glucosides in 14 Plantago L. species (44 samples corresponding to 18 taxa) was shown. P. tenuiflora and P. gentianoides were studied for iridoids for the first time. The iridoid patterns showed a good correlation with morphological and other chemical features of the representatives of genus Plantago. The studied species are grouped together according to the iridoi...
