Galls induced by insects can be viewed as an extended phenotype of the inducing insect, and gall-inducing insects specialize on their host plants, often to a greater extent than insects that feed on the same plant without creating galls. [2] The gall's form or type depends on what organism is attacking the plant and where the plant is being ...
Often multiple wasps in different life stages occupy the same gall. The induced galls help establish complex insect communities, promoting the diversification in niche differentiation. Furthermore, the adaptive value of these galls could be attributed their ecological benefits such as nutrition, provision of microenvironment, and enemy avoidance.
Gall-inducing insects are usually species-specific and sometimes tissue-specific on the plants they gall. Gall-inducing insects include gall wasps, gall midges, gall flies, leaf-miner flies, aphids, scale insects, psyllids, thrips, gall moths, and weevils. [36] Many gall insects remain to be described. Estimates range up to more than 210,000 ...
There are two types of first instar nymphs within galls: one type of nymph is thick-legged and attacks insects introduced into galls. Another type of nymph is normal-legged. [ 10 ] Monomorphic first-instar nymphs of Pemphigus dorocola attack moth larvae, a predator , when it is experimentally introduced to the gall. [ 11 ]
In the winter time galls of D. mayri are often opened by predators just as are the galls of D. rosae.These predators may be birds as in the case of other Cynipidae galls: for D. rosae the lesser spotted woodpecker (Picoides minor), [2] for Andricus spp. and Neuroterus spp. the great tit (Parus major).
Rhopalomyia is a genus of gall midges, insects in the family Cecidomyiidae. There are at least 267 described species in Rhopalomyia. [1] Most species in this genus induce galls on plants in the Asteraceae. [1] This genus has a cosmopolitan distribution. [1] Rhopalomyia was first established by Ewald Heinrich Rübsaamen in 1892. [1] Rhopalomyia ...
Cecidomyiidae is a family of flies known as gall midges or gall gnats. As the name implies, the larvae of most gall midges feed within plant tissue, creating abnormal plant growths called galls . Cecidomyiidae are very fragile small insects usually only 2–3 mm (0.079–0.118 in) in length; many are less than 1 mm (0.039 in) long.
