Many social aphids form spectacular galls on their host plants, in which hundreds to thousands of aphids thrive for several months or even for over a year. Here, in addition to colony defense against natural enemies, waste disposal is an important task for the gall dwellers to sustain their social life. In open galls, soldier nymphs actively clean colony wastes such as honeydew droplets, cast-off skins, and cadavers by pushing them with their head out of the gall opening. In the gall, the… 

Figures from this paper

Defensive nymphs and water‐repellency in previously unknown galls of the social aphid Colophina monstrifica (Hemiptera: Aphididae: Eriosomatinae)

Observations with a scanning electron microscope revealed that the gall inner surface was densely covered with minute trichomes, which indicates the water repellency of the inner surface, and suggests that young nymphs of C. monstrifica dispose of honeydew globules outside the gall, as known in the congener Colophina clematis.

Defensive nymphs in the water-repellent gall of the social aphid Colophina monstrifica (Hemiptera: Aphididae: Eriosomatinae)

Observations with a scanning electron microscope revealed that the gall inner surface was densely covered with minute trichomes, which indicates the water repellency of the inner surface, and strongly suggests that young nymphs of C. monstrifica dispose of honeydew globules outside the gall, as known in the congener C. clematis.

This manuscript calls for an integrated approach that incorporates such diverse fields as life-history theory, plant mate choice, wasp sexual selection and local mate competition, plant embryology as well as seed and fruit dispersal to jointly solve the many valuable questions that can be addressed in community ecology, co-evolution and species interaction biology.

Gall-Inducing Parasites: Convergent and Conserved Strategies of Plant Manipulation by Insects and Nematodes.

It is suggested that looking at similarities may identify convergent and conserved strategies and shed light on the promise they hold for the development of new management strategies in agriculture and forestry.

Phytohormones Regulate Both “Fish Scale” Galls and Cones on Picea koraiensis

The results indicate that the galls and cones are sink organs, and the development of gall tissues is possibly regulated by phytohormones in a way similar to that of the growth of cones.

Microscopic study of nine galls induced in Populus nigra by aphids of the Iberian Peninsula

The gall histological complexity is related to Pemphigini phylogeny, confirming the importance of such studies in galling aphid taxonomy and possible pathways of galling habit evolution, and a classification of all Eriosomatinae galls is proposed.

Scab formation and wound healing of plant tissue by soldier aphid

It is suggested that the novel system may have evolved in the aphid lineage through enhancement and recruitment of the pre-existing capabilities of haemolymph coagulation and gall formation, which occurs at an animal–plant interface.

Water-repellent plant surface structure induced by gall-forming insects for waste management

A unique type of water-repellent structure on a plant surface is reported, which develops as an insect-induced plant morphology in a social context, thereby realizing a high water repellency with a cooperative interaction between aphids and plants.

An insect-induced novel plant phenotype for sustaining social life in a closed system

A sophisticated biological solution to the waste problem in the closed system is reported: the gall inner surface is specialized for absorbing water, whereby honeydew is promptly removed via the plant vascular system.

Extremely Long-Closed Galls of a Social Aphid

It is found that galls of N. monzeni are initiated in June, that they remain small for at least 21–22 months and that tiny fundatrices survive for over one year, and some galls rapidly expand during April/May in the third year and some remain small and swell up in the fourth year and still others in the fifth year.

Self-sacrificing gall repair by aphid nymphs

It is reported that nymphs of the aphid Nipponaphis monzeni repair their gall self-sacrificingly, the most elaborate social behaviour so far known among aphids.

It is shown experimentally that the soldier caste of an aphid, the gall-forming Pemphigus spyrothecae, fulfils a second, non-defensive, altruistic role: the soldiers actively clean their gall.

Defensive behavior in the aphid Hamamelistes miyabei on its primary host plant, Hamamelis japonica, where it forms a spiny gall is found, and altruistic defenders are described in the primary host generation of an aphid from the tribe Hormaphidini.
