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 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...
متن کاملThe Description of Zapatella davisae, New Species, (Hymenoptera: Cynipidae) a Pest Gallwasp of Black Oak (Quercus velutina) in New England, USA
— Many species of gall wasp (Cynipidae) essentially co-exist with their host oak tree species. Occasionally, the association becomes destructive to the tree, as is the case with Zapatella davisae, new species. This species is a twig galler, and as such, in the cases of heavy infestation, cause flagging, leaf clumping, and dieback of branches and twigs. Historical records of other species of Zap...
متن کاملThe incidence and diversity of Wolbachia in gallwasps (Hymenoptera; Cynipidae) on oak.
Wolbachia bacteria infect approximately 20% of all insect species, and cause a range of alterations to host reproduction, including imposition of thelytoky. The incidence and phenotypic impact of Wolbachia remains to be established in many insect taxa, and considerable research effort is currently focused on its association with particular reproductive modes and the relative importance of the v...
متن کاملLife history, natural enemies, and management of Disholcaspis quercusvirens (Hymenoptera: Cynipidae) on live oak trees.
Live oak (Quercus virginiana Mill.) trees are hosts to a complex of gall making arthropods. However, the bullet galls produced by the asexual generation of the cynipid Disholcaspis quercuscirens (Ashmead) can esthetically and physically damage nursery and street trees, and thus reduce tree value. We sought to describe the unknown sexual generation of D. quercusvirens, describe the development o...
