Insect galls are dramatic examples of extended phenotypes: although composed of host plant tissues, their development is largely controlled by insect genes. Adaptive explanations for gall traits should thus be expressed in terms of impacts on insect fitness, but the extent to which interspecific variation in gall structure is adaptive, and the possible selective pressures driving Cited by: Egan et al. report the discovery of a new trophic interaction in nature whereby a parasitic plant attacks multiple species of insects that manipulate plant tissue when the two co-occur on a shared primary host plant.

On the biology of inhabitants of oak galls of Cynipidae (Hymenoptera) in Britain Article (PDF Available) January with Reads How we measure 'reads'. Abstract 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 Cited by: The most abundant inhabitants of dissected stem galls (n = 3, total insects in 81, mo old galls), included C.

Populations of Callirhytis cornigera (Osten Sacken) and its associated community of natural enemies and inquilines were monitored on pin oak, Quercus palustris Muenchhausen, in Lexington, KY, from to The gall wasp has alternating agamic and sexual generations that differ morphologically and develop in multichambered galls on branches and single.

This note is about galls formed on oak by gall wasps. Gall wasps are small, brown wasps with the abdomen flattened side to side. Abstract. The gall wasp Biorhiza pallida (Hymenoptera: Cynipidae) reproduces by cyclical parthenogenesis.
The adults of the sexual generation develop within galls (oak apples) that contain many larval cells. Folliot [() Annales Des Sciences Naturelles: Zoologie, 12, –] found asexual generation females to be of three reproductive by: Most of the information has been extracted from my Master’s degree final project (University of Barcelona, ), titled “Separation and identification of inquilines from the genus Synergus (Fam.
Cynipidae, Hymenoptera) from galls developed on Mexican species of Quercus”. Both fossil types can be unambiguously identified as galls induced by oak gallwasps (Hymenoptera: Cynipidae) on the basis of striking similarity to modern forms. No other gall inducers produce galls of this size and complexity in the Western Palaearctic (Docters van Cited by: Askew R R () On the biology of the inhabitants of oak galls of Cynipidae (Hymenoptera) in Britain.

Galls increase in size for about 24 months and may house as many as developing wasps. The hollow horns begin to project from galls that are about 2 years old and ultimately serve as escape tunnels. Galls harden and dry after their residents leave and the horns break off.

Cited by: A hyperparasite is a parasite whose host, often an insect, is also a parasite, often specifically a parasitoid. Hyperparasites are found mainly among the wasp-waisted Apocrita within the Hymenoptera, and in two other insect orders, the Diptera (true flies) and Coleoptera (beetles).
Seventeen families in Hymenoptera and a few species of Diptera and Coleoptera are hyperparasitic. Gall wasps, also called gallflies, are a family (Cynipidae) in the wasp superfamily Cynipoidea within the suborder Apocrita of the order common name comes from the galls they induce on plants for larval development.
About species of this generally very small creature (1–8 mm) are known worldwide, with about species of 36 different genera in Europe and some Class: Insecta. Askew RR () On the biology of the inhabitants of oak galls of Cynipidae (Hymenoptera) in Britain.
