Phospholipids and Lipid Acyl Hydrolase (Phospholipase) in Leaf Galls (Hymenoptera: Cynipidae of Black Oak [Quercus robor L.]).
Phosphatidylcholine, phosphatidylglycerol, phosphatidylethanolamine and cardiolipin are the major phospholipids in young leaves of black oak (Quercus robor L.). Except for phosphatidylcholine, young, developing cynipid-galls on black oak leaves, i.e. the insect-transformed tissues, contain less phospholipid than normal leaf tissues. Lipid acyl hydrolase activity determined by the cleavage of fr...

متن کاملFossil oak galls preserve ancient multitrophic interactions.
Trace fossils of insect feeding have contributed substantially to our understanding of the evolution of insect-plant interactions. The most complex phenotypes of herbivory are galls, whose diagnostic morphologies often allow the identification of the gall inducer. Although fossil insect-induced galls over 300Myr old are known, most are two-dimensional impressions lacking adequate morphological ...
متن کاملClumped distribution of oak leaf miners between and within plants
Leaf miners typically show non-random distributions both between and within plants. We tested the hypothesis that leaf miners on two oak species were clumped on individual host trees and individual branches and addressed whether clumping was influenced by aspects of plant quality and how clumping and/or interactions with other oak herbivores affected leaf-miner survivorship. Null models were us...
متن کاملThe population biology of oak gall wasps (Hymenoptera: Cynipidae).
Oak gall wasps (Hymenoptera: Cynipidae, Cynipini) are characterized by possession of complex cyclically parthenogenetic life cycles and the ability to induce a wide diversity of highly complex species- and generation-specific galls on oaks and other Fagaceae. The galls support species-rich, closed communities of inquilines and parasitoids that have become a model system in community ecology. We...
