Gall Induction

The molecular-based phylogenetic analysis of the subfamily Tephritinae, the subfamily that contains almost all the cecidogenous species of the family Tephritidae, has reassigned several tribes and groups of genera and modified their concepts based on morphology alone to other tribes and, thus, changed the hypothetical scenarios of evolution of fly/host–plant relations and, in particular, the gall induction in different phylogenetic lineages. Gall induction is shown to arise independently within the Myopitini (in two lineages), Cecidocharini, Tomoplagia group of genera, Eurostini, Eutreta, Tephritis group of genera, Platensinini, Campiglossa group of genera, and Sphenella group of genera independently and more or less synchronously due to the shift to host plants with smaller flower heads and sensitive to larval feeding causing tissue proliferation. This was possibly a result of temporary aridization of the grassy biomes in the Nearctic and Afrotropic regions in the late Miocene or early Pliocene.

Gall Induction

Galling insects commonly change the chemical profile of their host plant tissues during gall induction and establishment. As a consequence, galls accumulate a wide range of metabolites in specialized cells, which may be organized in a nutritive tissue and in outer storage cells. The nutrients compartmentalized in nutritive cells may be directly assessed or metabolized via enzymatic mediation, while the gall outer cortex may accumulate secondary metabolites. These secondary metabolitesmay configure a specialized chemical barrier against the attack of natural enemies. Either the nutritive inner cells or the outer cortical cells, with their specific metabolic apparatus, should differentiate under the chemical constraints of each host plant-galling herbivore interaction. This premise is herein addressed by the investigation of the histochemical profile of the non-galled leaves and galls induced by Diptera: Cecidomyiidae on Piper arboreum. The spatial compartmentalization of the nutritive and defensive metabolites indicates the new functions assumed during the redifferentiation of the host plant cells. The enzymatic mediation of the primary metabolites by sucrose synthase and invertases favors the nutritive requirements of the galling Cecidomyiidae or the structural maintenance of the gall. The accumulation of secondary metabolites is restrict to the tissue layers not involved in nutrition, and may act in the chemical protection against predators or parasitoids. Current results systematically document metabolites compartmentalization, evidence the impairment of toxic compounds storage in cells surrounding the larval chamber, as well as, detect the redirection of nutritive substances to the site of the Cecidomyiidae feeding. The activity of sucrose synthase is restrict to the nutritive tissue in the galls on Piper arboreum, and reinforces previous detection of this enzyme mediation in carbohydrate metabolism in Cecidomyiidae galls.

Gall Induction

AbstractThe chalcidoid wasp, Hemadas nubilipennis (Ashmead), induces a reniform gall on the adventitious shoots of lowbush blueberry. Eggs are laid within shoot tissues 5–15 mm below the tip and then the female destroys the apex of the shoot by stabbing with her ovipositor. Stabbing terminates growth of the shoot, and as a result all nutrients flowing into the shoot are redirected towards the gall tissues and larvae. This is a rare example of an insect damaging tissues of the host plant for the benefit of the offspring. It also is suggested that stabbing and gall formation have a pruning effect on the host plant.
