During a survey of the flat mites (Tenuipalpidae) on forest trees and agricultural crops in five different sites Apulian territories (Southern Italy) 2019, Brevipalpus recki (Livschitz Mitrofanov) Cenopalpus longirostris were collected Quercus pubescens (Willdenow) (Fagaceae). The authors give an account new record C. longirostris, which was not listed previous Italian fauna, finding B. souther...

Wind-pollinated forest trees usually have high outcrossing rates, but allogamy does not necessarily translate into high pollen movement. The goal of this study was to determine the outcrossing rates, pollen pool genetic structure, and the size of the effective pollination neighborhood in a population of black oak, Quercus velutina, in a Missouri oak-hickory forest. Based on 6 allozyme loci, 12 ...

This survey investigated the relationship between gall morphology and some fitness components in the asexual generation of Cynips quercusfolii L. (Hymenoptera: Cynipidae). Results showed that larger C. quercusfolii galls were formed on the south side of oak trees Quercus infectoria Olivier (Fagales: Fagaceae). Larval chamber diameter in the gall was similar, but gall diameter and gall wall thic...

The circular distributions of plant modulars (branches, leaves) and endophagous herbivory (mines, galls) were investigated within the crowns of four dominant Fagaceae trees in a subtropical evergreen broadleaf forest at Jiulianshan National Nature Reserve, Jiangxi, China. The hypothesis is that more plant modulars and more endophagous herbivory should occur in the crown area perpendicular to th...
