<span class="mw-page-title-main">Gall</span> Abnormal growths especially on plants induced by parasitic insects and other organisms

Galls or cecidia are a kind of swelling growth on the external tissues of plants, fungi, or animals. Plant galls are abnormal outgrowths of plant tissues, similar to benign tumors or warts in animals. They can be caused by various parasites, from viruses, fungi and bacteria, to other plants, insects and mites. Plant galls are often highly organized structures so that the cause of the gall can often be determined without the actual agent being identified. This applies particularly to some insect and mite plant galls. The study of plant galls is known as cecidology.

<span class="mw-page-title-main">Gall wasp</span> Superfamily of wasps

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.

<span class="mw-page-title-main">Oak apple</span> Gall found on oak trees

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.

<i>Andricus quercuscalicis</i> Species of wasp

Andricus quercuscalicis is a gall wasp species inducing knopper galls.

<i>Dryocosmus</i> Genus of wasps

Dryocosmus are a genus of gall wasps. They are cyclically parthenogenetic insects that induce galls on plants in the family Fagaceae.

<i>Andricus kollari</i> Species of insect

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.

<i>Andricus foecundatrix</i> Species of wasp

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.

<i>Neuroterus</i> Genus of wasps

Neuroterus is a genus of gall wasps that induce galls on oaks in which the wasp larvae live and feed. Some species produce galls that fall off the host plant and 'jump' along the ground due to the movement of the larvae within.

<i>Andricus lignicola</i> Species of wasp

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.

<i>Cynips</i> Genus of wasps

Cynips is a genus of gall wasps in the tribe Cynipini, the oak gall wasps. One of the best known is the common oak gall wasp, which induces characteristic spherical galls about two centimeters wide on the undersides of oak leaves.

<i>Andricus</i> Genus of wasps

Andricus is a genus of oak gall wasps in the family Cynipidae.

<i>Biorhiza pallida</i> Species of wasp

Biorhiza pallida is a gall wasp species in the family Cynipidae. This species is a member of the tribe Cynipini: the oak gall wasp tribe. Cynipini is the tribe partially responsible for the formation of galls known as oak apples on oak trees. These are formed after the wasp lays eggs inside the leaf buds and the plant tissues swell as the larvae of the gall wasp develop inside. This wasp has a widespread distribution within Europe.

<i>Dryocosmus kuriphilus</i> Species of wasp

Dryocosmus kuriphilus is a species of gall wasp known by the common names chestnut gall wasp, Oriental chestnut gall wasp, and Asian chestnut gall wasp. It is native to China and it is known in many other parts of the world, particularly the Northern Hemisphere, as an introduced species and an invasive horticultural pest. It attacks many species of chestnut, including most cultivated varieties. It is considered the world's worst pest of chestnuts.

<span class="mw-page-title-main">Cynipinae</span> Subfamily of insects

Cynipinae is a subfamily of gall wasps (Cynipidae). Many of the approximately 1,500 described species cause galls on oaks, but some induce galls on other plant species or are inquilines of the gall-inducing species. Species occur on all continents except Antarctica, with most found in the temperate regions of the northern hemisphere. All extant cynipid species are within Cynipinae since the only other recognized subfamily is Hodiernocynipinae which is based on the fossil genus Hodiernocynips.

<span class="mw-page-title-main">Cynipini</span> Tribe of wasps

Cynipini is a tribe of gall wasps. These insects induce galls in plants of the beech and oak family, Fagaceae. They are known commonly as the oak gall wasps. It is the largest cynipid tribe, with about 936 to 1000 recognized species, most of which are associated with oaks. The tribe is mainly native to the Holarctic. Cynipini wasps can act as ecosystem engineers. Their galls can become hosts of inquilines, and the wasps themselves are hosts to parasitoids.

<i>Trichagalma formosana</i> Species of wasp

Trichagalma formosana is a gall wasp species in the family Cynipidae whose life cycle involves only Palaearctic oaks, Quercus subgen. Quercus, in the section Cerris. It is endemic to Taiwan.

<i>Dryocosmus dubiosus</i> North American gall-inducing wasp

Dryocosmus dubiosus is an abundant species of cynipid wasp that produces galls on oak trees in California in North America. Commonly known as the two-horned gall wasp, the wasp oviposits on the leaves and catkins of coast live oaks and interior live oaks. After the eggs hatch, the resulting gall form looks like it has a set of bull's horns.
