Andricus hispanicus is a parthenogenetic species of wasp which causes the formation of marble galls on oak trees. The galls caused by the agamous generation are similar to the closely related Andricus kollari . [1]
Andricus hispanicus occurs in Portugal, Spain, southern France and North Africa, where the host of the sexual generation, Quercus suber , occurs. A. hispanicus was previously included in Andricus kollari, but the two are genetically distinct [2] and require different hosts to complete their life cycle. [1]
Both species have alternating sexual and asexual generations. [3] Sexual females lay their eggs in the developing buds of several species of white oaks using their ovipositor. The wasp causes the formation of a round gall, where the larvae develop until they are ready to emerge as asexual females. Through parthenogenesis, these asexual females produce unfertilised eggs that are deposited on the buds of Quercus suber in Andricus hispanicus, or Quercus cerris in Andricus kollari. As these eggs develop, a small, inconspicuous gall forms around on the bud, different from that formed by the previous generation. [3] The unfertilised eggs give rise to a new sexual generation of adult males and females, which mate and restart the cycle. [3] [1]
Experiments have shown that asexual females of Andricus hispanicus will readily oviposit into buds of Quercus suber but show no interest in Quercus cerris, while the reverse is true for Andricus kollari'. [1]
Quercus cerris, the Turkey oak or Austrian oak, is an oak native to south-eastern Europe and Asia Minor. It is the type species of Quercus sect. Cerris, a section of the genus characterised by shoot buds surrounded by soft bristles, bristle-tipped leaf lobes, and acorns that usually mature in 18 months.
Gall wasps, also traditionally calledgallflies, are hymenopterans of the family Cynipidae in the wasp superfamily Cynipoidea. Their common name comes from the galls they induce on plants for larval development. About 1,300 species of this generally very small creature are known worldwide, with about 360 species of 36 different genera in Europe and some 800 species in North America.
Oak apple or oak gall is the common name for a large, round, vaguely apple-like gall commonly found on many species of oak. Oak apples range in size from 2 to 4 centimetres in diameter and are caused by chemicals injected by the larva of certain kinds of gall wasp in the family Cynipidae.
Andricus quercuscalicis is a gall wasp species inducing knopper galls.
Andricus kollari, also known as the marble gall wasp, is a parthenogenetic species of wasp which causes the formation of marble galls on oak trees. Synonyms for the species include Cynips kollari, Andricus quercusgemmae, A. minor, A. indigenus and A. circulans.
Andricus foecundatrix is a parthenogenetic gall wasp which lays a single egg within a leaf bud, using its ovipositor, to produce a gall known as an oak artichoke gall, oak hop gall, larch-cone gall or hop strobile The gall develops as a chemically induced distortion of leaf axillary or terminal buds on pedunculate oak or sessile oak trees. The larva lives inside a smaller hard casing inside the artichoke and this is released in autumn. The asexual wasp emerges in spring and lays her eggs in the oak catkins. These develop into small oval galls which produce the sexual generation of wasps. A yew artichoke gall caused by the fly Taxomyia taxi also exists, but is unrelated to the oak-borne species. Previous names or synonyms for the species A. fecundator are A. fecundatrix, A. pilosus, A. foecundatrix, A. gemmarum, A. gemmae, A. gemmaequercus, A. gemmaecinaraeformis and A. quercusgemmae.
Cola-nut galls develop as a chemically induced distortion of leaf axillary or terminal buds on pedunculate oak or sessile oak trees, caused by the agamic gall wasp Andricus lignicola which lays single eggs within leaf buds using their ovipositor. A previous name or synonym for the species A. lignicola is A. lignicolus and A. venheurni.
Neuroterus numismalis is a gall wasp that forms chemically induced leaf galls on oak trees. It has both bisexual and agamic (parthenogenetic) generations and forms two distinct galls on oak leaves, the silk button gall and blister gall. The galls can be very numerous with more than a thousand per leaf.
Neuroterus anthracinus is a widely distributed gall wasp that forms chemically induced leaf galls on oak trees. N. anthracinus has both sexual and agamic generations and in consequence forms two distinct galls, the oyster gall and April-bud gall.
Cynips quercusfolii, also known as the cherry gall wasp, is a gall wasp species in the genus Cynips and family Cynipidae. The species is important for the production of commercial nutgall formed on Quercus lusitanica . Galls are located on the underside of leaves, with the majority of galls being on the second and third veins from the petiole of the leaf.
Andricus is a genus of oak gall wasps in the family Cynipidae.
Andricus grossulariae is a gall wasp species inducing agamic acorn cup galls on oak tree acorn cups and sexual phase galls on catkins. Synonyms include Andricus fructuum, Andricus gemellus, Andricus intermedius, Andricus mayri and Cynips panteli.
Andricus aries is a species of gall-forming wasps, in the genus Andricus. The species was named by the French entomologist Joseph-Étienne Giraud, in 1859. It is commonly found in eastern Europe and during the 21st century has spread to western Europe.
Aphelonyx kordestanica is a gall wasp species in the family Cynipidae whose life cycle involves only Palaearctic oaks, Quercus subgen. Quercus, in the section Cerris.
Andricus curvator is a gall wasp which forms chemically induced leaf galls on oak trees and has both agamic and sexual generations. Agamic and sexual generations usually form two distinct galls on oak trees, but in the case of A. curvator there are six galls; the sexual generation usually on the leaf, occasionally in a twig or catkin, and the agamic generation in a bud. The wasp was first described by Theodor Hartig, a German biologist, in 1840 and is found in most of Europe.
Andricus corruptrix is a species of gall-forming wasp, in the genus Andricus. It is found in Europe.
Andricus inflator is a species of gall-forming wasps, in the genus Andricus, which has a sexual and an asexual generation, producing two different galls. The wasp was named by the German biologist Theodor Hartig, in 1840 and is found in Europe.
Andricus infectorius is a species of gall-forming wasp. The species was named by the German biologist Theodor Hartig, in 1843 and is found in Europe.
Andricus mukaigawae is a species of gall wasp native to southeastern Asia. It creates galls on the buds and leaves of oak trees. The galls are sometimes used by other gall wasps unable to create galls of their own, with both species sharing the gall.
Disholcaspis quercusmamma, the oak rough bulletgall wasp, is a species of gall wasp in the family Cynipidae. The quercus in its name is the genus name for oak, while "mamma" is Latin for "breast", presumably a reference to the "nipple" on the gall.
