The reproduction of gall wasps is usually partly parthenogenesis, in which a male is completely unnecessary, and partly two-sex propagation. [2] Most species have alternating generations, with one two-sex generation and one parthenogenic generation annually, whereas some species produce very few males and reproduce only by parthenogenesis, [2] possibly because of infection of the females ...
Andricus quercuscalifornicus (occasionally Andricus californicus), or the California gall wasp, is a small wasp species that induces oak apple galls on white oaks, primarily the valley oak (Quercus lobata) but also other species such as Quercus berberidifolia.
Diplolepis rosae is a gall wasp which causes a gall known as the rose bedeguar gall, bedeguar gall wasp, Robin's pincushion, mossy rose gall, or simply moss gall. [ 1 ] [ 2 ] The gall develops as a chemically induced distortion of an unopened leaf axillary or terminal bud, mostly on field rose ( Rosa arvensis ) or dog rose ( Rosa canina ) shrubs.
Acraspis quercushirta, the jewel oak gall wasp, is a species of gall wasp in the family Cynipidae, [2] [3] tribe Cynipini (oak gall wasps), [4] found in North America. [ 5 ] [ 6 ] Hosts are white oaks , including bur oak , Gambel oak , Chapman oak , swamp chestnut oak , and chestnut oak .
The wasp oviposits on shrub live oak and Gambel oak leaves. [1] The larval chamber is at the center of the gall, connected to the husk by slender, radiating fibers. [1] This wasp is most commonly observed in the American Southwest, as far north as Denver. [2] It is visually similar to, and may be confused with, Atrusca bella. [1]
Andricus quercusstrobilanus, the lobed oak gall wasp, is a species [1] of gall wasp in the family Cynipidae, [2] found in North America. [3] The quercus in its specific name is the genus name for oak, while "strobilus" is derived from the Greek strobilo which means "cone", a reference to the cone shape of the gall; [4] thus the gall is sometimes called pine cone oak gall.
Besbicus mirabilis, formerly Cynips mirabilis, also known as the speckled gall wasp, is a common species of cynipid wasp that produces galls on oak trees in North America. [1] This wasp oviposits on the midrib of the underside (with rare dorsal-side exceptions) of Oregon oak leaves. [1] One to three detachable galls per leaf have been observed. [1]
Andricus quercuscalicis is a gall wasp species inducing knopper galls.. Knopper galls develop as a chemically induced distortion of growing acorns on pedunculate oak (Quercus robur L.) trees, caused by gall wasps, which lay eggs in buds with their ovipositor.
