The larva of Seticeros aquilus (Thomson), collected in Quercus humboldtii (Fagaceae) in Colombia, is described and illustrated. Biological notes and a comparison with the larva of Chorenta reticulata described by Duffy (1960) and with the descriptions of the other South American Callipogonini species are presented.

In many but not all recalcitrant Quercus seeds, water loss during drying only occurs through the scar. Consequently, embryo axis sitting on opposite side of scar is well protected from desiccation. However, whether such a mechanism common throughout Fagaceae species unexplored. Similarly, little known about desiccation response other genera. Germination and tolerance Castanopsis sclerophylla (L...

A new genus and two new species belonging to subfamily Cecidophyinae, namely Kyllocarus reticulatusgen.n., sp. n. infesting Lithocarpus brevicaudatus (Skan) Hay. (Fagaceae) and Gammaphytoptus schimaesp. n.infesting Schima superba Gardn. et Champ. (Theaceae) are described and illustrated. Both new species are vagrants on their respective host plants. Cecidophyes digephyrusKeifer, 1966 is newly r...

Cerchysiella mesosae Yang sp. nov. (Hymenoptera: Chalcidoidea: Encyrtidae), is described from China. It is a gregarious koinobiont endoparasitoid in mature larvae of Mesosa myops (Dalman) (Coleoptera: Cerambycidae), a wood boring pest of many broad-leaved tree species in China, particularly Quercus mongolica and Q. liaotungensis (Fagaceae) in forest areas of northeastern China. The new species ...

A new species, Quercus xuanlienensis Binh, Ngoc & Bon, is described from Xuan Lien Nature Reserve, Vietnam. The new species is morphologically similar to Q. edithiae Skan, in having 8-11 pairs of secondary veins, bowl-shaped cupules and ellipsoid to cylindrical-ellipsoid and basally convex nuts. It differs in having serrulate leaf margins only at apical 1/5-1/7, almost entire margins of bracts ...

We investigated clonal population structure and genetic variation in Quercus havardii (sand-shinnery oak), a deciduous rhizomatous shrub that dominates vegetation by forming uninterrupted expanses of ground cover over sandy deposits on the plains of western Texas, western Oklahoma, and eastern New Mexico. Isozyme electrophoresis (15 loci coding 11 enzymes) was used to recognize and map clones a...

The present study aimed at evaluating the antibacterial activity of methanol extract of Ruta chalapensis, L., (Rutaceae), Quercus infectoria Oliver., (Fagaceae) and Canthium parviflorum Lam., (Rubiaceae) against Staphylococcus aureus, Pseudomonas aeruginosa, Enterococcus faecalis, Klebsiella oxytocoa, Klebsiella pneumoniae and Proteus mirabilis. The experiment was carried out using disc diffusi...

This paper reports two new species of Bdellidae, Cyta leliae sp. nov. and Cyta kurdistanicus sp. nov., collected from soil and litter under oak trees, Quercus brantii Lindl. (Fagaceae), wild almond, Amygdalus lycioides Spach (Rosaceae) and grass, Kurdistan Province, Iran. A key is provided to adult female Cyta of the world. 

Quercus ningangensis is an economically and ecologically important tree species belonging to the family Fagaceae. In this study, complete chloroplast (cp) genome of Q. was sequenced assembled, 18 published cp genomes were retrieved for genomic analyses (including sequence divergence, repeat elements, structure) phylogenetic inference. With we found that in are conserved, discovered a codon comp...
